Description

[0001] Despite interdisciplinary approaches and exhaustive use of classical therapeutic procedures, cancers are still among the leading causes of death. More recent therapeutic concepts aim at incorporating the patient's immune system into the overall therapeutic concept by using recombinant tumor vaccines and other specific measures such as antibody therapy. A prerequisite for the success of such a strategy is the recognition of tumor-specific or tumor-associated antigens or epitopes by the patient's immune system whose effector functions are to be interventionally enhanced. Tumor cells biologically differ substantially from their nonmalignant cells of origin. These differences are due to genetic alterations acquired during tumor development and result, inter alia, also in the formation of qualitatively or quantitatively altered molecular structures in the cancer cells. Tumor-associated structures of this kind which are recognized by the specific immune system of the tumor-harboring host are referred to as tumor-associated antigens. The specific recognition of tumor-associated antigens involves cellular and humoral mechanisms which are two functionally interconnected units: CD.sup.4 and CD8.sup.+ T lymphocytes recognize the processed antigens presented on the molecules of the MHC (major histocompatibility complex) classes II and I, respectively, while B lymphocytes produce circulating antibody molecules which bind directly to unprocessed antigens. The potential clinical-therapeutical importance of tumor-associated antigens results from the fact that the recognition of antigens on neoplastic cells by the immune system leads to the initiation of cytotoxic effector mechanisms and, in the presence of T helper cells, can cause elimination of the cancer cells (Pardoll, Nat. Med. 4:525-31, 1998). Accordingly, a central aim of tumor immunology is to molecularly define these structures. The molecular nature of these antigens has been enigmatic for a long time. Only after development of appropriate cloning techniques has it been possible to screen cDNA expression libraries of tumors systematically for tumor-associated antigens by analyzing the target structures of cytotoxic T lymphocytes (CTL) (van der Bruggen et al., Science 254:1643-7, 1991) or by using circulating autoantibodies (Sahin et al., Curr. Opin. Immunol. 9:709-16, 1997) as probes. To this end, cDNA expression libraries were prepared from fresh tumor tissue and recombinantly expressed as proteins in suitable systems. Immunoeffectors isolated from patients, namely CTL clones with tumor-specific lysis patterns, or circulating autoantibodies were utilized for cloning the respective antigens.

[0002] In recent years a multiplicity of antigens have been defined in various neoplasias by these approaches. The class of cancer/testis antigens (CTA) is of great interest here. CTA and genes encoding them (cancer/testis genes or CTG) are defined by their characteristic expression pattern [Tureci et al, Mol Med Today. 3:342-9, 1997]. They are not found in normal tissues, except testis and germ cells, but are expressed in a number of human malignomas, not tumor type-specifically but with different frequency in tumor entities of very different origins (Chen & Old, Cancer J. Sci. Am. 5:16-7, 1999). Serum reactivities against CTA are also not found in healthy controls but only in tumor patients. This class of antigens, in particular owing to its tissue distribution, is particularly valuable for immunotherapeutic projects and is tested in current clinical patient studies (Marchand et al., Int. J. Cancer 80:219-30, 1999; Knuth et al., Cancer Chemother. Pharmacol. 46:p 46-51, 2000).

[0003] However, the probes utilized for antigen identification in the classical methods illustrated above are immunoeffectors (circulating autoantibodies or CTL clones) from patients usually having already advanced cancer. A number of data indicate that tumors can lead, for example, to tolerization and anergization of T cells and that, during the course of the disease, especially those specificities which could cause effective immune recognition are lost from the immunoeffector repertoire. Current patient studies have not yet produced any solid evidence of a real action of the previously found and utilized tumor-associated antigens. Accordingly, it cannot be ruled out that proteins evoking spontaneous immune responses are the wrong target structures.

[0004] It was the object of the present invention to provide target structures for a diagnosis and therapy of cancers.

[0005] According to the invention, this object is achieved by the subject matter of the claims.

[0006] According to the invention, a strategy for identifying and providing antigens expressed in association with a tumor and the nucleic acids coding therefor was pursued. This strategy is based on the fact that actually testis- and thus germ cell-specific genes which are usually silent in adult tissues are reactivated in tumor cells in an ectopic and forbidden manner. First, data mining produces a list as complete as possible of all known testis-specific genes which are then evaluated for their aberrant activation in tumors by expression analyses by means of specific RT-PCR. Data mining is a known method of identifying tumor-associated genes. In the conventional strategies, however, transcriptoms of normal tissue libraries are usually subtracted electronically from tumor tissue libraries, with the assumption that the remaining genes are tumor-specific (Schmitt et al., Nucleic Acids Res. 27:4251-60, 1999; Vasmatzis et al., Proc. Natl. Acad. Sci. USA. 95:300-4, 1998. Scheurle et al., Cancer Res. 60:4037-43, 2000).

[0007] The concept of the invention, which has proved much more successful, however, is based on utilizing data mining for electronically extracting all testis-specific genes and then evaluating said genes for ectopic expression in tumors.

[0008] The invention thus relates in one aspect to a strategy for identifying genes differentially expressed in tumors. Said strategy combines data mining of public sequence libraries ("in silico") with subsequent evaluating laboratory-experimental ("wet bench") studies.

[0009] According to the invention, a combined strategy based on two different bioinformatic scripts enabled new members of the cancer/testis (CT) gene class to be identified. These have previously been classified as being purely testis-, germ cell- or sperm-specific. The finding that these genes are aberrantly activated in tumor cells allows them to be assigned a substantially new quality with functional implications. According to the invention, these tumor-associated genes and the genetic products encoded thereby were identified and provided independently of an immunogenic action.

[0010] The tumor-associated antigens identified according to the invention have an amino acid sequence encoded by a nucleic acid which is selected from the group consisting of (a) a nucleic acid which comprises a nucleic acid sequence selected from the group consisting of SEQ ID NOs: 1-5, 19-21, 29, 31-33, 37, 39, 40, 54-57, 62, 63, 70, 74, 85-88, a part or derivative thereof, (b) a nucleic acid which hybridizes with the nucleic acid of (a) under stringent conditions, (c) a nucleic acid which is degenerate with respect to the nucleic acid of (a) or (b), and (d) a nucleic acid which is complementary to the nucleic acid of (a), (b) or (c). In a preferred embodiment, a tumor-associated antigen identified according to the invention has an amino acid sequence encoded by a nucleic acid which is selected from the group consisting of SEQ ID NOs: 1-5, 19-21, 29, 31-33, 37, 39, 40, 54-57, 62, 63, 70, 74, 85-88. In a further preferred embodiment, a tumor-associated antigen identified according to the invention comprises an amino acid sequence selected from the group consisting of SEQ ID NOs: 6-13, 14-18, 22-24, 30, 34-36, 38, 41, 58-61, 64, 65, 71, 75, 80-84, 89-100, a part or derivative thereof.

[0011] The present invention generally relates to the use of tumor-associated antigens identified according to the invention or of parts thereof, of nucleic acids coding therefor or of nucleic acids directed against said coding nucleic acids or of antibodies directed against the tumor-associated antigens identified according to the invention or parts thereof for therapy and diagnosis. This utilization may relate to individual but also to combinations of two or more of these antigens, functional fragments, nucleic acids, antibodies, etc., in one embodiment also in combination with other tumor-associated genes and antigens for diagnosis, therapy and progress control.

[0012] Preferred diseases for a therapy and/or diagnosis are those in which one or more of the tumor-associated antigens identified according to the invention are selectively expressed or abnormally expressed.

[0013] The invention also relates to nucleic acids and genetic products' which are expressed in association with a tumor cell and which are produced by altered splicing (splice variants) of known genes or by altered translation with utilization of alternative open reading frames. Said nucleic acids comprise the sequences according to (SEQ ID NO: 2-5, 20, 21, 31-33, 54-57, 85-88) of the sequence listing. Furthermore, the genetic products comprise sequences according to (SEQ ID NO: 7-13, 23, 24, 34-36, 58-61, 89-100) of the sequence listing. The splice variants of the invention can be used according to the invention as targets for diagnosis and therapy of neoplastic diseases.

[0014] Very different mechanisms may cause splice variants to be produced, for example

[0015] utilization of variable transcription initiation sites

[0016] utilization of additional exons

[0017] complete or incomplete splicing out of single or two or more exons,

[0018] splice regulator sequences altered via mutation (deletion or generation of new donor/acceptor sequences),

[0019] incomplete elimination of intron sequences.

[0020] Altered splicing of a gene results in an altered transcript sequence (splice variant). Translation of a splice variant in the region of its altered sequence results in an altered protein which may be distinctly different in the structure and function from the original protein. Tumor-associated splice variants may produce tumor-associated transcripts and tumor-associated proteins/antigens. These may be utilized as molecular markers both for detecting tumor cells and for therapeutic targeting of tumors. Detection of tumor cells, for example in blood, serum, bone marrow, sputum, bronchial lavage, bodily secretions and tissue biopsies, may be carried out according to the invention, for example, after extraction of nucleic acids by PCR amplification with splice variant-specific oligonucleotides. According to the invention, all sequence-dependent detection systems are suitable for detection. These are, apart from PCR, for example gene chip/microarray systems, Northern blot, RNAse protection assays (FDA) and others. All detection systems have in common that detection is based on a specific hybridization with at least one splice variant-specific nucleic acid sequence. However, tumor cells may also be detected according to the invention by antibodies which recognize a specific epitope encoded by the splice variant. Said antibodies may be prepared by using for immunization peptides which are specific for said splice variant. Suitable for immunization are particularly the amino acids whose epitopes are distinctly different from the variant(s) of the genetic product, which is (are; preferably produced in healthy cells. Detection of the tumor cells with antibodies may be carried out here on a sample isolated from the patient or as imaging with intravenously administered antibodies. In addition to diagnostic usability, splice variants having new or altered epitopes are attractive targets for immunotherapy. The epitopes of the invention may be utilized for targeting therapeutically active monoclonal antibodies or T lymphocytes. In passive immunotherapy, antibodies or T lymphocytes which recognize splice variant-specific epitopes are adoptively transferred here. As in the case of other antigens, antibodies may be generated also by using standard technologies (immunization of animals, panning strategies for isolation of recombinant antibodies) with utilization of polypeptides which include these epitopes. Alternatively, it is possible to utilize for immunization nucleic acids coding for oligo- or polypeptides which contain said epitopes. Various techniques for in vitro or in vivo generation of epitope-specific T lymphocytes are known and have been described in detail, for example (Kessler J H, et al. 2001, Sahin et al., 1997) and are likewise based on utilizing oligo- or polypeptides which contain the splice variant-specific epitopes or nucleic acids coding for said oligo- or polypeptides. Oligo- or polypeptides which contain the splice variant-specific epitopes or nucleic acids coding for said polypeptides may also be used for utilization as pharmaceutically active substances in active immunotherapy (vaccination, vaccine therapy).

Conceptionally, said therapeutic approaches may aim at inhibiting the activity of the selectively expressed tumor-associated genetic product. This is useful, if said aberrant respective selective expression is functionally important in tumor pathogenicity and if its ligation is accompanied by selective damage of the corresponding cells. Other therapeutic concepts contemplate tumor-associated antigens as labels which recruit effector mechanisms having cell-damaging potential selectively to tumor cells. Here, the function of the target molecule itself and its role in tumor development are totally irrelevant.

[0059] "Derivative" of a nucleic acid means according to the invention that single or multiple nucleotide substitutions, deletions and/or additions are present in said nucleic acid. Furthermore, the term "derivative" also comprises chemical derivatization of a nucleic acid on a nucleotide base, on the sugar or on the phosphate. The term "derivative" also comprises nucleic acids which contain nucleotides and nucleotide analogs not occurring naturally.

[0060] According to the invention, a nucleic acid is preferably deoxyribonucleic acid (DNA) or ribonucleic acid (RNA). Nucleic acids comprise according to the invention genomic DNA, cDNA, mRNA, recombinantly produced and chemically synthesized molecules. According to the invention, a nucleic acid may be present as a single-stranded or double-stranded and linear or covalently circularly closed molecule.

[0061] The nucleic acids described according to the invention have preferably been isolated. The term "isolated nucleic acid" means according to the invention that the nucleic acid was (i) amplified in vitro, for example by polymerase chain reaction (PCR), (ii) recombinantly produced by cloning, (iii) purified, for example by cleavage and gel-electrophoretic fractionation, or (iv) synthesized, for example by chemical synthesis. An isolated nucleic acid is a nucleic acid which is available for manipulation by recombinant DNA techniques.

[0062] A nucleic acid is "complementary" to another nucleic acid if the two sequences are capable of hybridizing and forming a stable duplex with one another, with hybridization preferably being carried out under conditions which allow specific hybridization between polynucleotides (stringent conditions). Stringent conditions are described, for example, in Molecular Cloning: A Laboratory Manual, J. Sambrook et al., Editors, 2nd Edition, Cold Spring Harbor Laboratory press, Cold Spring Harbor, N.Y., 1989 or Current Protocols in Molecular Biology, F. M. Ausubel et al., Editors, John Wiley & Sons, Inc., New York and refer, for example, to hybridization at 65.degree. C. in hybridization buffer (3.5.times.SSC, 0.02% Ficoll, 0.02% polyvinylpyrrolidone, 0.02% bovine serum albumin, 2.5 mM NaH.sub.2PO.sub.4 (pH 7), 0.5% SDS, 2 mM EDTA). SSC is 0.15 M sodium chloride/0.15 M sodium citrate, pH 7. After hybridization, the membrane to which the DNA has been transferred is washed, for example, in 2.times.SSC at room temperature and then in 0.1-0.5.times.SSC/0.1.times.SDS at temperatures of up to 68.degree. C.

[0063] According to the invention, complementary nucleic acids have at least 40%, in particular at least 50%, at least 60%, at least 70%, at least 80%, at least 90% and preferably at least 95%, at least 98 or at least 99%, identical nucleotides.

[0064] Nucleic acids coding for tumor-associated antigens may, according to the invention, be present alone or in combination with other nucleic acids, in particular heterologous nucleic acids. In preferred embodiments, a nucleic acid is functionally linked to expression control sequences or regulatory sequences which may be homologous or heterologous with respect to said nucleic acid. A coding sequence and a regulatory sequence are "functionally" linked to one another, if they are covalently linked to one another in such a way that expression or transcription of said coding sequence is under the control or under the influence of said regulatory sequence. If the coding sequence is to be translated into a functional protein, then, with a regulatory sequence functionally linked to said coding sequence, induction of said regulatory sequence results in transcription of said coding sequence, without causing a frame shift in the coding sequence or said coding sequence not being capable of being translated into the desired protein or peptide.

[0065] The term "expression control sequence" or "regulatory sequence" comprises according to the invention promoters, enhancers and other control elements which regulate expression of a gene. In particular embodiments of the invention, the expression control sequences can be regulated. The exact structure of regulatory sequences may vary as a function of the species or cell type, but generally comprises 5'untranscribed and 5'untranslated sequences which are involved in initiation of transcription and translation, respectively, such as TATA box, capping sequence, CAAT sequence, and the like. More specifically, 5'untranscribed regulatory sequences comprise a promoter region which includes a promoter sequence for transcriptional control of the functionally linked gene. Regulatory sequences may also comprise enhancer sequences or upstream activator sequences.

[0066] Thus, on the one hand, the tumor-associated antigens illustrated herein may be combined with any expression control sequences and promoters. On the other hand, however, the promoters of the tumor-associated genetic products illustrated herein may, according to the invention, be combined with any other genes. This allows the selective activity of these promoters to be utilized.

[0067] According to the invention, a nucleic acid may furthermore be present in combination with another nucleic acid which codes for a polypeptide controlling secretion of the protein or polypeptide encoded by said nucleic acid from a host cell. According to the invention, a nucleic acid may also be present in combination with another nucleic acid which codes for a polypeptide causing the encoded protein or polypeptide to be anchored on the cell membrane of the host cell or compartmentalized into particular organelles of said cell.

[0068] In a preferred embodiment, a recombinant DNA molecule is according to the invention a vector, where appropriate with a promoter, which controls expression of a nucleic acid, for example a nucleic acid coding for a tumor-associated antigen of the invention. The term "vector" is used here in its most general meaning and comprises any intermediary vehicle for a nucleic acid which enables said nucleic acid, for example, to be introduced into prokaryotic and/or eukaryotic cells and, where appropriate, to be integrated into a genome. Vectors of this kind are preferably replicated and/or expressed in the cells. An intermediary vehicle may be adapted, for example, to the use in electroporation, in bombardment with microprojectiles, in liposomal administration, in the transfer with the aid of agrobacteria or in insertion via DNA or RNA viruses. Vectors comprise plasmids, phagemids or viral genomes. The nucleic acids coding for a tumor-associated antigen identified according to the invention may be used for transfection of host cells. Nucleic acids here mean both recombinant DNA and RNA. Recombinant RNA may be prepared by in-vitro transcription of a DNA template. Furthermore, it may be modified by stabilizing sequences, capping and polyadenylation prior to application. According to the invention, the term "host cell" relates to any cell which can be transformed or transfected with an exogenous nucleic acid. The term "host cells" comprises according to the invention prokaryotic (e.g. E. coli) or eukaryotic cells (e.g. dendritic cells, B cells, CHO cells, COS cells, K562 cells, yeast cells and insect cells). Particular preference is given to mammalian cells such as cells from humans, mice, hamsters, pigs, goats, primates. The cells may be derived from a multiplicity of tissue types and comprise primary cells and cell lines. Specific examples comprise keratinocytes, peripheral blood leukocytes, stem cells of the bone marrow and embryonic stem cells. In further embodiments, the host cell is an antigen-presenting cell, in particular a dendritic cell, monocyte or a macrophage. A nucleic acid may be present in the host cell in the form of a single copy or of two or more copies and, in one embodiment is expressed in the host cell.

[0069] According to the invention, the term "expression" is used in its most general meaning and comprises the production of RNA or of RNA and protein. It also comprises partial expression of nucleic acids. Furthermore, expression may be carried out transiently or stably. Preferred expression systems in mammalian cells comprise pcDNA3.1 and pRc/CMV (Invitrogen, Carlsbad, Calif.), which contain a selective marker such as a gene imparting resistance to G418 (and thus enabling stably transfected cell lines to be selected) and the enhancer-promoter sequences of cytomegalovirus (CMV).

[0070] In those cases of the invention in which an HLA molecule presents a tumor-associated antigen or a part thereof, an expression vector may also comprise a nucleic acid sequence coding for said HLA molecule. The nucleic acid sequence coding for the HLA molecule may be present on the same expression vector as the nucleic acid coding for the tumor-associated antigen or the part thereof, or both nucleic acids may be present on different expression vectors. In the latter case, the two expression vectors may be cotransfected into a cell. If a host cell expresses neither the tumor-associated antigen or the part thereof nor the HLA molecule, both nucleic acids coding therefor are transfected into the cell either on the same expression vector or on different expression vectors. If the cell already expresses the HLA molecule, only the nucleic acid sequence coding for the tumor-associated antigen or the part thereof can be transfected into the cell.

[0071] The invention also comprises kits for amplification of a nucleic acid coding for a tumor-associated antigen. Such kits comprise, for example, a pair of amplification primers which hybridize to the nucleic acid coding for the tumor-associated antigen. The primers preferably comprise a sequence of 6-50, in particular 10-30, 15-30 and 20-30 contiguous nucleotides of the nucleic acid and are nonoverlapping, in order to avoid the formation of primer dimers. One of the primers will hybridize to one strand of the nucleic acid coding for the tumor-associated antigen, and the other primer will hybridize to the complementary strand in an arrangement which allows amplification of the nucleic acid coding for the tumor-associated antigen.

[0072] "Antisense" molecules or "antisense" nucleic acids may be used for regulating, in particular reducing, expression of a nucleic acid. The term "antisense molecule" or "antisense nucleic acid" refers according to the invention to an oligonucleotide which is an oligoribonucleotide, oligodeoxyribonucleotide, modified oligoribonucleotide or modified oligodeoxyribonucleotide and which hybridizes under physiological conditions to DNA comprising a particular gene or to mRNA of said gene, thereby inhibiting transcription of said gene and/or translation of said mRNA. According to the invention, the "antisense molecule" also comprises a construct which contains a nucleic acid or a part thereof in reverse orientation with respect to its natural promoter. An antisense transcript of a nucleic acid or of a part thereof may form a duplex with the naturally occurring mRNA specifying the enzyme and thus prevent accumulation of or translation of the mRNA into the active enzyme. Another possibility is the use of ribozymes for inactivating a nucleic acid. Antisense oligonucleotides preferred according to the invention have a sequence of 6-50, in particular 10-30, 15-30 and 20-30, contiguous nucleotides of the target nucleic acid and preferably are fully complementary to the target nucleic acid or to a part thereof.

[0073] In preferred embodiments, the antisense oligonucleotide hybridizes with an N-terminal or 5' upstream site such as a translation initiation site, transcription initiation site or promoter site. In further embodiments, the antisense oligonucleotide hybridizes with a 3'untranslated region or mRNA splicing site.

[0074] In one embodiment, an oligonucleotide of the invention consists of ribonucleotides, deoxyribonucleotides or a combination thereof, with the 5' end of one nucleotide and the 3' end of another nucleotide being linked to one another by a phosphodiester bond. These oligonucleotides may be synthesized in the conventional manner or produced recombinantly.

[0075] In preferred embodiments, an oligonucleotide of the invention is a "modified" oligonucleotide. Here, the oligonucleotide may be modified in very different ways, without impairing its ability to bind its target, in order to increase, for example, its stability or therapeutic efficacy. According to the invention, the term "modified oligonucleotide" means an oligonucleotide in which (i) at least two of its nucleotides are linked to one another by a synthetic internucleoside bond (i.e. an internucleoside bond which is not a phosphodiester bond) and/or (ii) a chemical group which is usually not found in nucleic acids is covalently linked to the oligonucleotide. Preferred synthetic internucleoside bonds are phosphorothioates, alkyl phosphonates, phosphorodithioates, phosphate esters, alkyl phosphonothioates, phosphoramidates, carbamates, carbonates, phosphate triesters, acetamidates, carboxymethyl esters and peptides.

[0076] The term "modified oligonucleotide" also comprises oligonucleotides having a covalently modified base and/or sugar. "Modified oligonucleotides" comprise, for example, oligonucleotides with sugar residues which are covalently bound to low molecular weight organic groups other than a hydroxyl group at the 3' position and a phosphate group at the 5' position. Modified oligonucleotides may comprise, for example, a 2'-O-alkylated ribose residue or another sugar instead of ribose, such as arabinose.

[0077] Preferably, the proteins and polypeptides described according to the invention have been isolated. The terms "isolated protein" or "isolated polypeptide" mean that the protein or polypeptide has been separated from its natural environment. An isolated protein or polypeptide may be in an essentially purified state. The term "essentially purified" means that the protein or polypeptide is essentially free of other substances with which it is associated in nature or in vivo.

[0078] Such proteins and polypeptides may be used, for example, in producing antibodies and in an immunological or diagnostic assay or as therapeutics. Proteins and polypeptides described according to the invention may be isolated from biological samples such as tissue or cell homogenates and may also be expressed recombinantly in a multiplicity of pro- or eukaryotic expression systems.

[0079] For the purposes of the present invention, "derivatives" of a protein or polypeptide or of an amino acid sequence comprise amino acid insertion variants, amino acid deletion variants and/or amino acid substitution variants.

[0080] Amino acid insertion variants comprise amino- and/or carboxy-terminal fusions and also insertions of single or two or more amino acids in a particular amino acid sequence. In the case of amino acid sequence variants having an insertion, one or more amino acid residues are inserted into a particular site in an amino acid sequence, although random insertion with appropriate screening of the resulting product is also possible. Amino acid deletion variants are characterized by the removal of one or more amino acids from the sequence. Amino acid substitution variants are characterized by at least one residue in the sequence being removed and another residue being inserted in its place. Preference is given to the modifications being in positions in the amino acid sequence which are not conserved between homologous proteins or polypeptides. Preference is given to replacing amino acids with other ones having similar properties such as hydrophobicity, hydrophilicity, electronegativity, volume of the side chain and the like (conservative substitution). Conservative substitutions, for example, relate to the exchange of one amino acid with another amino acid listed below in the same group as the amino acid to be substituted:

[0081] 1. small aliphatic, nonpolar or slightly polar residues: Ala, Ser, Thr (Pro, Gly)

[0082] 2. negatively charged residues and their amides: Asn, Asp, Glu, Gln

[0083] 3. positively charged residues: His, Arg, Lys

[0084] 4. large aliphatic, nonpolar residues: Met, Leu, Ile, Val (Cys)

[0085] 5. large aromatic residues: Phe, Tyr, Trp.

[0086] Owing to their particular part in protein architecture, three residues are shown in brackets. Gly is the only residue without a side chain and thus imparts flexibility to the chain. Pro has an unusual geometry which greatly restricts the chain. Cys can form a disulfide bridge.

[0087] The amino acid variants described above may be readily prepared with the aid of known peptide synthesis techniques such as, for example, by solid phase synthesis (Merrifield, 1964) and similar methods or by recombinant DNA manipulation. Techniques for introducing substitution mutations at predetermined sites into DNA which has a known or partially known sequence are well known and comprise M13 mutagenesis, for example. The manipulation c. DNA sequences for preparing proteins having substitutions, insertions or deletions, is described in detail in Sambrook et al. (1989), for example.

[0088] According to the invention, "derivatives" of proteins or polypeptides also comprise single or multiple substitutions, deletions and/or additions of any molecules associated with the enzyme, such as carbohydrates, lipids and/or proteins or polypeptides. The term "derivative" also extends to all functional chemical equivalents of said proteins or polypeptides. According to the invention, a part or fragment of a tumor-associated antigen has a functional property of the polypeptide from which it has been derived. Such functional properties comprise the interaction with antibodies, the interaction with other polypeptides or proteins, the selective binding of nucleic acids and an enzymatic activity. A particular property is the ability to form a complex with HLA and, where appropriate, generate an immune response. This immune response may be based on stimulating cytotoxic or T helper cells. A part or fragment of a tumor-associated antigen of the invention preferably comprises a sequence of at least 6, in particular at least 8, at least 10, at least 12, at least 15, at least 20, at least 30 or at least 50, consecutive amino acids of the tumor-associated antigen.

[0089] A part or a fragment of a nucleic acid coding for a tumor-associated antigen relates according to the invention to the part of the nucleic acid, which codes at least for the tumor-associated antigen and/or for a part or a fragment of said tumor-associated antigen, as defined above.

[0090] The isolation and identification of genes coding for tumor-associated antigens also make possible the diagnosis of a disease characterized by expression of one or more tumor-associated antigens. These methods comprise determining one or more nucleic acids which code for a tumor-associated antigen and/or determining the encoded tumor-associated antigens and/or peptides derived therefrom. The nucleic acids may be determined in the conventional manner, including by polymerase chain reaction or hybridization with a labeled probe. Tumor-associated antigens or peptides derived therefrom may be determined by screening patient antisera with respect to recognizing the antigen and/or the peptides. They may also be determined by screening T cells of the patient for specificities for the corresponding tumor-associated antigen.

[0091] The present invention also enables proteins binding to tumor-associated antigens described herein to be isolated, including antibodies and cellular binding partners of said tumor-associated antigens.

[0092] According to the invention, particular embodiments ought to involve providing "dominant negative" polypeptides derived from tumor-associated antigens. A dominant negative polypeptide is an inactive protein variant which, by way of interacting with the cellular machinery, displaces an active protein from its interaction with the cellular machinery or which competes with the active protein, thereby reducing the effect of said active protein. For example, a dominant negative receptor which binds to a ligand but does not generate any signal as response to binding to the ligand can reduce the biological effect of said ligand. Similarly, a dominant negative catalytically inactive kinase which usually interacts with target proteins but does not phosphorylate said target proteins may reduce phosphorylation of said target proteins as response to a cellular signal. Similarly, a dominant negative transcription factor which binds to a promoter site in the control region of a gene but does not increase transcription of said gene may reduce the effect of a normal transcription factor by occupying promoter binding sites, without increasing transcription.

[0093] The result of expression of a dominant negative polypeptide in a cell is a reduction in the function of active proteins. The skilled worker may prepare dominant negative variants of a protein, for example, b, conventional mutagenesis methods and by evaluating the dominant negative effect of the variant polypeptide.

[0094] The invention also comprises substances such as polypeptides which bind to tumor-associated antigens. Such binding substances may be used, for example, in screening assays for detecting tumor-associated antigens and complexes of tumor-associated antigens with their binding partners and in a purification of said tumor-associated antigens and of complexes thereof with their binding partners. Such substances may also be used for inhibiting the activity of tumor-associated antigens, for example by binding to such antigens.

[0095] The invention therefore comprises binding substances such as, for example, antibodies or antibody fragments, which are capable of selectively binding to tumor-associated antigens. Antibodies comprise polyclonal and monoclonal antibodies which are produced in the conventional manner.

[0096] It is known that only a small part of an antibody molecule, the paratope, is involved in binding of the antibody to its epitope (cf. Clark, W. R. (1986), The Experimental Foundations of Modern Immunology, Wiley & Sons, Inc., New York; Roitt, I. (1991), Essential Immunology, 7th Edition, Blackwell Scientific Publications, Oxford). The pFc' and Fc regions are, for example, effectors of the complement cascade but are not involved in antigen binding. An antibody from which the pFc' region has been enzymatically removed or which has been produced without the pFc' region, referred to as F(ab').sub.2 fragment, carries both antigen binding sites of a complete antibody. Similarly, an antibody from which the Fc region has been enzymatically removed or which has been produced without said Fc region, referred to Fab fragment, carries one antigen binding site of an intact antibody molecule. Furthermore, Fab fragments consist of a covalently bound light chain of an antibody and part of the heavy chain of said antibody, referred to as Fd. The Fd fragments are the main determinants of antibody specificity (a single Fd fragment can be associated with up to ten different light chains, without altering the specificity of the antibody) and Ed fragments, when isolated, retain the ability to bind to an epitope.

[0097] Located within the antigen-binding part of an antibody are complementary-determining regions (CDRs) which interact directly with the antigen epitope and framework regions (FRs) which maintain the tertiary structure of the paratope. Both the Fd fragment of the heavy chain and the light chain of IgG immunoglobulins contain four framework regions (FR1 to FR4) which are separated in each case by three complementary-determining regions (CDR1 to CDR3). The CDRs and, in particular, the CDR3 regions and, still more particularly, the CDR3 region of the heavy chain are responsible to a large extent for antibody specificity.

[0098] Non-CDR regions of a mammalian antibody are known to be able to be replaced by similar regions of antibodies with the same or a different specificity, with the specificity for the epitope of the original antibody being retained. This made possible the development of "humanized" antibodies in which nonhuman CDRs are covalently linked to human FR and/or Fc/pFc' regions to produce a functional antibody.

[0099] WO 92/04381 for example, describes production and use of humanized murine RSV antibodies in which at least part of the murine FR regions have been replaced with FR regions of a human origin. Antibodies of this kind, including fragments of intact antibodies with antigen-binding capability, are often referred to as "chimeric" antibodies.

[0100] The invention also provides F(ab').sub.2, Fab, Fv, and Fd fragments of antibodies, chimeric antibodies, in which the Fc and/or FR and/or CDR1 and/or CDR2 and/or light chain-CDR3 regions have been replaced with homologous human or nonhuman sequences, chimeric F(ab').sub.2-fragment antibodies in which the FR and/or CDR1 and/or CDR2 and/or light chain-CDR3 regions have been replaced with homologous human or nonhuman sequences, chimeric Fab-fragment antibodies in which the FR and/or CDR1 and/or CDR2 and/or light chain-CDR3 regions have been replaced with homologous human or nonhuman sequences, and chimeric Fd-fragment antibodies in which the FR and/or CDR1 and/or CDR2 regions have been replaced with homologous human or nonhuman sequences. The invention also comprises "single-chain" antibodies.

[0101] The invention also comprises polypeptides which bind specifically to tumor-associated antigens. Polypeptide binding substances of this kind may be provided, for example, by degenerate peptide libraries which may be prepared simply in solution in an immobilized form or as phage-display libraries. It is likewise possible to prepare combinatorial libraries of peptides with one or more amino acids. Libraries of peptoids and nonpeptidic synthetic residues may also be prepared.

[0102] Phage display may be particularly effective in identifying binding peptides of the invention. In this connection, for example, a phage library is prepared (using, for example, the M13, fd or lambda phages) which presents inserts of from 4 to about 80 amino acid residues in length. Phages are then selected which carry inserts which bind to the tumor-associated antigen. This process may be repeated via two or more cycles of a reselection of phages binding to the tumor-associated antigen. Repeated rounds result in a concentration of phages carrying particular sequences. An analysis of DNA sequences may be carried out in order to identify the sequences of the expressed polypeptides. The smallest linear portion of the sequence binding to the tumor-associated antigen may be determined. The "two-hybrid system" of yeast may also be used for identifying polypeptides which bind to a tumor-associated antigen. Tumor-associated antigens described according to the invention or fragments thereof may be used for screening peptide libraries, including phage-display libraries, in order to identify and select peptide binding partners of the tumor-associated antigens. Such molecules may be used, for example, for screening assays, purification protocols, for interference with the function of the tumor-associated antigen and for other purposes known to the skilled worker.

[0103] The antibodies described above and other binding molecules may be used, for example, for identifying tissue which expresses a tumor-associated antigen. Antibodies may also be coupled to specific diagnostic substances for displaying cells and tissues expressing tumor-associated antigens. They may also be coupled to therapeutically useful substances. Diagnostic substances comprise, in a nonlimiting manner, barium sulfate, iocetamic acid, iopanoic acid, calcium ipodate, sodium diatrizoate, meglumine diatrizoate, metrizamide, sodium tyropanoate and radio diagnostic, including positron emitters such as fluorine-18 and carbon-11, gamma emitters such as iodine-123, technetium-99m, iodine-131 and indium-111, nuclides for nuclear magnetic resonance, such as fluorine and gadolinium. According to the invention, the term "therapeutically useful substance" means any therapeutic molecule which, as desired, is selectively guided to a cell which expresses one or more tumor-associated antigens, including anticancer agents, radioactive iodine-labeled compounds, toxins, cytostatic or cytolytic drugs, etc. anticancer agents comprise, for example, aminoglutethimide, azathioprine, bleomycin sulfate, busulfan, carmustine, chlorambucil, cisplatin, cyclophosphamide, cyclosporine, cytarabidine, dacarbazine, dactinomycin, daunorubin, doxorubicin, taxol, etoposide, fluorouracil, interferon-.alpha., lomustine, mercaptopurine, methotrexate, mitotane, procarbazine HCl, thioguanine, vinblastine sulfate and vincristine sulfate. Other anticancer agents are described, for example, in Goodman and Gilman, "The Pharmacological Basis of Therapeutics", 8th Edition, 1990, McGraw-Hill, Inc., in particular Chapter 52 (Antineoplastic Agents (Paul Calabresi and Bruce A. Chabner). Toxins may be proteins such as pokeweed antiviral protein, cholera toxin, pertussis toxin, ricin, gelonin, abrin, diphtheria exotoxin or Pseudomonas exotoxin. Toxin residues may also be high energy-emitting radionuclides such as cobalt-60.

[0104] The term "patient" means according to the invention a human being, a nonhuman primate or another animal, in particular a mammal such as a cow, horse, pig, sheep, goat, dog, cat or a rodent such as a mouse and rat. In a particularly preferred embodiment, the patient is a human being.

[0105] According to the invention, the term "disease" refers to any pathological state in which tumor-associated antigens are expressed or abnormally expressed. "Abnormal expression" means according to the invention that expression is altered, preferably increased, compared to the state in a healthy individual. An increase in expression refers to an increase by at least 10%, in particular at least 20%, at least 50% or at least 100%. In one embodiment, the tumor-associated antigen is expressed only in tissue of a diseased individual, while expression in a healthy individual is repressed. One example of such a disease is cancer, in particular seminomas, melanomas, teratomas, gliomas, colorectal cancer, breast cancer, prostate cancer, cancer of the uterus, ovarian cancer and lung cancer.

[0106] According to the invention, a biological sample may be a tissue sample and/or a cellular sample and may be obtained in the conventional manner such as by tissue biopsy, including punch biopsy, and by taking blood, bronchial aspirate, urine, feces or other body fluids, for use in the various methods described herein.

[0107] According to the invention, the term "immunoreactive cell" means a cell which can mature into an immune cell (such as B cell, T helper cell, or cytolytic T cell) with suitable stimulation. Immunoreactive cells comprise CD34.sup.+ hematopoietic stem cells, immature and mature T cells and immature and mature B cells. If production of cytolytic or T helper cells recognizing a tumor-associated antigen is desired, the immunoreactive cell is contacted with a cell expressing a tumor-associated antigen under conditions which favor production, differentiation and/or selection of cytolytic T cells and of T helper cells. The differentiation of T cell precursors into a cytolytic T cell, when exposed to an antigen, is similar to clonal selection of the immune system.

[0108] Some therapeutic methods are based on a reaction of the immune system of a patient, which results in a lysis of antigen-presenting cells such as cancer cells which present one or more tumor-associated antigens. In this connection, for example autologous cytotoxic T lymphocytes specific for a complex of a tumor-associated antigen and an MHC molecule are administered to a patient having a cellular abnormality. The production of such cytotoxic T lymphocytes in vitro is known. An example of a method of differentiating T cells can be found in WO-A-9633265. Generally, a sample containing cells such as blood cells is taken from the patient and the cells are contacted with a cell which presents the complex and which can cause propagation of cytotoxic T lymphocytes (e.g. dendritic cells). The target cell may be a transfected cell such as a COS cell. These transfected cells present the desired complex on their surface and, when contacted with cytotoxic T lymphocytes, stimulate propagation of the latter. The clonally expanded autologous cytotoxic T lymphocytes are then administered to the patient.

[0109] In another method of selecting antigen-specific cytotoxic T lymphocytes, fluorogenic tetramers of MHC class I molecule/peptide complexes are used for detecting specific clones of cytotoxic T lymphocytes (Altman et al., Science 274:94-96, 1996; Dunbar et al., Curr. Biol. 8:413-416, 1998). Soluble MHC class I molecules are folded in vitro in the presence of .beta..sub.2 microglobulin and a peptide antigen binding to said class I molecule. The MHC/peptide complexes are purified and then labeled with biotin. Tetzamers are formed by mixing the biotinylated peptide-MHC complexes with labeled avidin (e.g. phycoerythrin) in a molar ratio of 4:1. Tetramers are then contacted with cytotoxic T lymphocytes such as peripheral blood or lymph nodes. The tetramers bind to cytotoxic T lymphocytes which recognize the peptide antigen/MHC class I complex. Cells which are bound to the tetramers may be sorted by fluorescence-controlled cell sorting to isolate reactive cytotoxic T lymphocytes. The isolated cytotoxic T lymphocytes may then be propagated in vitro.

[0110] In a therapeutic method referred to as adoptive transfer (Greenberg, J. Immunol. 136(5):1917, 1986; Riddel et al., Science 257:238, 1992; Lynch et al., Eur. J. Immunol. 21:1403-1410, 1991; Kast et al., Cell 59:603-614, 1989), cells presenting the desired complex (e.g. dendritic cells) are combined with cytotoxic T lymphocytes of the patient to be treated, resulting in a propagation of specific cytotoxic T lymphocytes. The propagated cytotoxic T lymphocytes are then administered to a patient having a cellular anomaly characterized by particular abnormal cells presenting the specific complex. The cytotoxic T lymphocytes then lyse the abnormal cells, thereby achieving a desired therapeutic effect.

[0111] Often, of the T cell repertoire of a patient, only T cells with low affinity for a specific complex of this kind can be propagated, since those with high affinity have been extinguished due to development of tolerance. An alternative here may be a transfer of the T cell receptor itself. For this too, cells presenting the desired complex (e.g. dendritic cells) are combined with cytotoxic T lymphocytes of healthy individuals. This results in propagation of specific cytotoxic T lymphocytes with high affinity if the donor had no previous contact with the specific complex. The high affinity T cell receptor of these propagated specific T lymphocytes is cloned and can be transduced via gene transfer, for example using retroviral vectors, into T cells of other patients, as desired. Adoptive transfer is then carried out using these genetically altered T lymphocytes (Stanislawski et al., Nat Immunol. 2:962-70, 2001; Kessels et al., Nat Immunol. 2:957-61, 2001).

[0112] The therapeutic aspects above start out from the fact that at least some of the abnormal cells of the patient present a complex of a tumor-associated antigen and an HLA molecule. Such cells may be identified in a manner known per se. As soon as cells presenting the complex have been identified, they may be combined with a sample from the patient, which contains cytotoxic T lymphocytes. If the cytotoxic T lymphocytes lyse the cells presenting the complex, it can be assumed that a tumor-associated antigen is presented.

[0113] Adoptive transfer is not the only form of therapy which can be applied according to the invention. Cytotoxic T lymphocytes may also be generated in vivo in a manner known per se. One method uses nonproliferative cells expressing the complex. The cells used here will be those which usually express the complex, such as irradiated tumor cells or cells transfected with one or both genes necessary for presentation of the complex (i.e. the antigenic peptide and the presenting HLA molecule). Various cell types may be used. Furthermore, it is possible to use vectors which carry one or both of the genes of interest. Particular preference is given to viral or bacterial vectors. For example, nucleic acids coding for a tumor-associated antigen or for a part thereof may be functionally linked to promoter and enhancer sequences which control expression of said tumor-associated antigen or a fragment thereof in particular tissues or cell types. The nucleic acid may be incorporated into an expression vector. Expression vectors may be nonmodified extrachromosomal nucleic acids, plasmids or viral genomes into which exogenous nucleic acids may be inserted. Nucleic acids coding for a tumor-associated antigen may also be inserted into a retroviral genome, thereby enabling the nucleic acid to be integrated into the genome of the target tissue or target cell. In these systems, a microorganism such as vaccinia virus, pox virus, Herpes simplex virus, retrovirus or adenovirus carries the gene of interest and de facto "infects" host cells. Another preferred form is the introduction of the tumor-associated antigen in the form of recombinant RNA which may be introduced into cells by liposomal transfer or by electroporation, for example. The resulting cells present the complex of interest and are recognized by autologous cytotoxic T lymphocytes which then propagate.

[0114] A similar effect can be achieved by combining the tumor-associated antigen or a fragment thereof with an adjuvant in order to make incorporation into antigen-presenting cells in vivo possible. The tumor-associated antigen or a fragment thereof may be represented as protein, as DNA (e.g. within a vector) or as RNA. The tumor-associated antigen is processed to produce a peptide partner for the HLA molecule, while a fragment thereof may be presented without the need for further processing. The latter is the case in particular, if these can bind to HLA molecules. Preference is given to administration forms in which the complete antigen is processed in vivo by a dendritic cell, since this may also produce T helper cell responses which are needed for an effective immune response (Ossendorp et al., Immunol Lett. 74:75-9, 2000; Ossendorp et al., J. Exp. Med. 187:693-702, 1998). In general, it is possible to administer an effective amount of the tumor-associated antigen to a patient by intradermal injection, for example. However, injection may also be carried out intranodally into a lymph node (Maloy et al., Proc Natl Acad Sci USA 98:3299-303, 2001). It may also be carried out in combination with reagents which facilitate uptake into dendritic cells. In vivo preferred tumor-associated antigens comprise those which react with allogenic cancer antisera or with T cells of many cancer patients. Of particular interest, however, are those against which no spontaneous immune responses pre-exist. Evidently, it is possible to induce against these immune responses which can lyse tumors (Keogh et al., J. Immunol. 167:787-96, 2001; Appella et al., Biomed Pept Proteins Nucleic Acids 1:177-84, 1995; Wentworth et al., Mol Immunol. 32:603-12, 1995).

[0115] The pharmaceutical compositions described according to the invention may also be used as vaccines for immunization. According to the invention, the terms "immunization" or "vaccination" mean an increase in or activation of an immune response to an antigen. It is possible to use animal models for testing an immunizing effect on cancer by using a tumor-associated antigen or a nucleic acid coding therefor. For example, human cancer cells may be introduced into a mouse to generate a tumor, and one or more nucleic acids coding for tumor-associated antigens may be administered. The effect on the cancer cells (for example reduction in tumor size) may be measured as a measure for the effectiveness of an immunization by the nucleic acid.

[0116] As part of the composition for an immunization, one or more tumor-associated antigens or stimulating fragments thereof are administered together with one or more adjuvants for inducing an immune response or for increasing an immune response. An adjuvant is a substance which is incorporated into the antigen or administered together with the latter and which enhances the immune response. Adjuvants may enhance the immune response by providing an antigen reservoir (extracellularly or in macrophages), activating macrophages and stimulating particular lymphocytes. Adjuvants are known and comprise in a nonlimiting way monophosphoryl lipid A (MPL, SmithKline Beecham), saponin such as QS21 (SmithKline Beecham), DQS21 (SmithKline Beecham; WO 96/33739), QS7, QS17, QS18 and QS-L1 (So et al., Mol. Cells 7:178-186, 1997), incomplete Freund's adjuvant, complete Freund's adjuvant, vitamin E, montanide, alum, CpG oligonucleotides (cf. Kreig et al., Nature 374:546-9, 1995) and various water-in-oil emulsions prepared from biologically degradable oils such as squalene and/or tocopherol. Preferably, the peptides are administered in a mixture with DQS21/MPL. The ratio of DQS21 to MPL is typically about 1:10 to 10:1, preferably about 1:5 to 5:1 and in particular about 1:1. For administration to humans, a vaccine formulation typically contains DQS21 and MPL in a range from about 1 .mu.g to about 100 .mu.g.

[0117] Other substances which stimulate an immune response of the patient may also be administered. It is possible, for example, to use cytokines in a vaccination, owing to their regulatory properties on lymphocytes. Such cytokines comprise, for example, interleukin-12 (IL-12) which was shown to increase the protective actions of vaccines (cf. Science 268:1432-1434, 1995), GM-CSF and IL-18.

[0118] There are a number of compounds which enhance an immune response and which therefore may be used in a vaccination. Said compounds comprise costimulating molecules provided in the form of proteins or nucleic acids. Examples of such costimulating molecules are B7-1 and B7-2 (CD80 and CD86, respectively) which are expressed on dendritic cells (DC) and interact with the CD28 molecule expressed on the T cells. This interaction provides a costimulation (signal 2) for an antigen/MHC/TCR-stimulated (signal 1) T cell, thereby enhancing propagation of said T cell and the effector function. B7 also interacts with CTLA4 (CD152) on T cells, and studies involving CTLA4 and B7 ligands demonstrate that B7-CTLA4 interaction can enhance antitumor immunity and CTL propagation (Zheng, P. et al., Proc. Natl. Acad. Sci. USA 95(11):6284-6289 (1998)).

[0119] B7 is typically not expressed on tumor cells so that these are no effective antigen-presenting cells (APCs) far T cells. Induction of B7 expression would enable rumor cells to stimulate more effectively propagation of cytotoxic T lymphocytes and an effector function. Costimulation by a combination of B7/IL-6/IL-12 revealed induction of IFN-gamma and Th1-cytokine profile in a T cell population, resulting in further enhanced T cell activity (Gajewski et al., J. Immunol. 154:5637-5648 (1995)).

[0120] A complete activation of cytotoxic T lymphocytes and a complete effector function require an involvement of T helper cells via interaction between the CD40 ligand on said T helper cells and the CD40 molecule expressed by dendritic cells (Ridge et al., Nature 393:474 (1998), Bennett et al., Nature 393:478 (1998), Schonberger et al., Nature 393:480 (1998)). The mechanism of this costimulating signal probably relates to the increase in B7 production and associated IL-6/IL-12 production by said dendritic cells (antigen-presenting cells). CD40-CD40L interaction thus complements the interaction of signal 1 (antigen/MHC-TCR) and signal 2 (B7-CD28).

[0121] The use of anti-CD40 antibodies for stimulating dendritic cells would be expected to directly enhance a response to tumor antigens which are usually outside the range of an inflammatory response or which are presented by nonprofessional antigen-presenting cells (tumor cells). In these situations, T helper and B7-costimulating signals are not provided. This mechanism could be used in connection with therapies based on antigen-pulsed dendritic cells or in situations in which T helper epitopes have not been defined in known TRA precursors.

[0122] The invention also provides for administration of nucleic acids, polypeptides or peptides. Polypeptides and peptides may be administered in a manner known per se. In one embodiment, nucleic acids are administered by ex vivo methods, i.e. by removing cells from a patient, genetic modification of said cells in order to incorporate a tumor-associated antigen and reintroduction of the altered cells into the patient. This generally comprises introducing a functional copy of a gene into the cells of a patient in vitro and reintroducing the genetically altered cells into the patient. The functional copy of the gene is under the functional control of regulatory elements which allow the gene to be expressed in the genetically altered cells. Transfection and transduction methods are known to the skilled worker. The invention also provides for administering nucleic acids in vivo by using vectors such as viruses and target-controlled liposomes.

[0123] In a preferred embodiment, a viral vector for administering a nucleic acid coding for a tumor-associated antigen is selected from the group consisting of adenoviruses, adeno-associated viruses, pox viruses, including vaccinia virus and attenuated pox viruses, Semliki Forest virus, retroviruses, Sindbis virus and Ty virus-like particles. Particular preference is given to adenoviruses and retroviruses. The retroviruses are typically replication-deficient (i.e. they are incapable of generating infectious particles).

[0124] Various methods may be used in order to introduce according to the invention nucleic acids into cells in vitro or in vivo. Methods of this kind comprise transfection of nucleic acid CaPO.sub.4 precipitates, transfection of nucleic acids associated with DEAE, transfection or infection with the above viruses carrying the nucleic acids of interest, liposome-mediated transfection, and the like. In particular embodiments, preference is given to directing the nucleic acid to particular cells. In such embodiments, a carrier used for administering a nucleic acid to a cell (e.g. a retrovirus or a liposome) may have a bound target control molecule. For example, a molecule such as an antibody specific for a surface membrane protein on the target cell or a ligand for a receptor on the target cell may be incorporated into or attached to the nucleic acid carrier. Preferred antibodies comprise antibodies which bind selectively a tumor-associated antigen. If administration of a nucleic acid via liposomes is desired, proteins binding to a surface membrane protein associated with endocytosis may be incorporated into the liposome formulation in order to make target control and/or uptake possible. Such proteins comprise capsid proteins or fragments thereof which are specific for a particular cell type, antibodies to proteins which are internalized, proteins addressing an intracellular site, and the like.

[0125] The therapeutic compositions of the invention may be administered in pharmaceutically compatible preparations. Such preparations may usually contain pharmaceutically compatible concentrations of salts buffer substances, preservatives, carriers, supplementing immunity-enhancing substances such as adjuvants, CpG and cytokines and, where appropriate, other therapeutically active compounds.

[0126] The therapeutically active compounds of the invention may be administered via any conventional route, including by injection or infusion. The administration may be carried out, for example, orally, intravenously, intraperitonealy, intramuscularly, subcutaneously or transdermally. Preferably, antibodies are therapeutically administered by way of a lung aerosol. Antisense nucleic acids are preferably administered by slow intravenous administration.

[0127] The compositions of the invention are administered in effective amounts. An "effective amount" refers to the amount which achieves a desired reaction or a desired effect alone or together with further doses. In the case of treatment of a particular disease or of a particular condition characterized by expression of one or more tumor-associated antigens, the desired reaction relates to inhibition of the course of the disease. This comprises slowing down the progress of the disease and, in particular, interrupting the progress of the disease. The desired reaction in a treatment of a disease or of a condition may also be delay of the onset or a prevention of the onset of said disease or said condition.

[0128] An effective amount of a composition of the invention will depend on the condition to be treated, the severeness of the disease, the individual parameters of the patient, including age, physiological condition, size and weight, the duration of treatment, the type of an accompanying therapy (if present), the specific route of administration and similar factors.

[0129] The pharmaceutical compositions of the invention are preferably sterile and contain an effective amount of the therapeutically active substance to generate the desired reaction or the desired effect.

[0130] The doses administered of the compositions of the invention may depend on various parameters such as the type of administration, the condition of the patient, the desired period of administration, etc. In the case that a reaction in a patient is insufficient with an initial dose, higher doses (or effectively higher doses achieved by a different, more localized route of administration) may be used.

[0131] Generally, doses of the tumor-associated antigen of from 1 ng to 1 mg, preferably from 10 ng to 100 .mu.g, are formulated and administered for a treatment or for generating or increasing an immune response. If the administration of nucleic acids (DNA and RNA) coding for tumor-associated antigens is desired, doses of from 1 ng to 0.1 mg are formulated and administered.

[0132] The pharmaceutical compositions of the invention are generally administered in pharmaceutically compatible amounts and in pharmaceutically compatible compositions. The term "pharmaceutically compatible" refers to a nontoxic material which does not interact with the action of the active component of the pharmaceutical composition. Preparations of this kind may usually contain salts, buffer substances, preservatives, carriers and, where appropriate, other therapeutically active compounds. When used in medicine, the salts should be pharmaceutically compatible. However, salts which are not pharmaceutically compatible may used for preparing pharmaceutically compatible salts and are included in the invention. Pharmacologically and pharmaceutically compatible salts of this kind comprise in a nonlimiting way those prepared from the following acids: hydrochloric, hydrobromic, sulfuric, nitric, phosphoric, maleic, acetic, salicylic, citric, formic, malonic, succinic acids, and the like. Pharmaceutically compatible salts may also be prepared as alkali metal salts or alkaline earth metal salts, such as sodium salts, potassium salts or calcium salts.

[0133] A pharmaceutical composition of the invention may comprise a pharmaceutically compatible carrier. According to the invention, the term "pharmaceutically compatible carrier" refers to one or more compatible solid or liquid fillers, diluents or encapsulating substances, which are suitable for administration to humans. The term "carrier" refers to an organic or inorganic component, of a natural or synthetic nature, in which the active component is combined in order to facilitate application. The components of the pharmaceutical composition of the invention are usually such that no interaction occurs which substantially impairs the desired pharmaceutical efficacy.

[0134] The pharmaceutical compositions of the invention may contain suitable buffer substances such as acetic acid in a salt, citric acid in a salt, boric acid in a salt and phosphoric acid in a salt.

[0135] The pharmaceutical compositions may, where appropriate, also contain suitable preservatives such as benzalkonium chloride, chlorobutanol, paraben and thimerosal.

[0136] The pharmaceutical compositions are usually provided in a uniform dosage form and may be prepared in a manner known per se. Pharmaceutical compositions of the invention may be in the form of capsules, tablets, lozenges, suspensions, syrups, elixir or in the form of an emulsion, for example.

[0137] Compositions suitable for parenteral administration usually comprise a sterile aqueous or nonaqueous preparation of the active compound, which is preferably isotonic to the blood of the recipient. Examples of compatible carriers and solvents are Ringer solution and isotonic sodium chloride solution. In addition, usually sterile, fixed oils are used as solution or suspension medium.

[0138] The present invention is described in detail by the figures and examples below, which are used only for illustration purposes and are not meant to be limiting. Owing to the description and the examples, further embodiments which are likewise included in the invention are accessible to the skilled worker.

EXAMPLES

Material and Methods

[0155] The terms "in silico", "electronic" and "virtual cloning" refer solely to the utilization of methods based on databases, which may also be used to simulate laboratory experimental processes.

[0156] Unless expressly defined otherwise, all other terms and expressions are used so as to be understood by the skilled worker. The techniques and methods mentioned are carried out in a manner known per se and are described, for example, in Sambrook et al., Molecular Cloning: A Laboratory Manual, 2nd Edition (1989) Cold Spring Harbor Laboratory Press, Cold Spring Harbor, N.Y. All methods including the use of kits and reagents are carried out according to the manufacturers' information.

Datamining-Based Strategy for Determining eCT (Electronically Cloned Cancer/Testis Genes)

[0157] Two in silico strategies, namely GenBank keyword search and the cDNAxProfiler, were combined (FIG. 1). Utilizing the NCBI ENTREZ Search and Retrieval System (http://www.ncbi.nlm.nih.gov/Entrez), a GenBank search was carried out for candidate genes annotated as being specifically expressed in testicular tissue (Wheeler et al., Nucleic Acids Research 28:10-14, 2000). Carrying out queries with the keywords "testis-specific gene", "sperm-specific gene", "spermatogonia-specific gene", candidate genes (GOI, genes of interest) were extracted from the databases. The search was restricted to part of the total information of these databases by using the limits "homo sapiens", for the organism, and "mRNA", for the type of molecule.

[0158] The list of the GOI found was curated by determining different names for the same sequence and eliminating such redundancies.

[0159] All candidate genes obtained by the keyword search were in turn studied with respect to their tissue distribution by the "electronic Northern" (eNorthern) method. The eNorthern is based on aligning the sequence of a GOI with an EST (expressed sequence tag) database (Adams et al., Science 252:1651, 1991) (http://www.ncbi.nlm.nih.gov/BLAST). The tissue origin of each EST which is found to be homologous to the GOI can be determined and in this way the sum of all ESTs produces a preliminary assessment of the tissue distribution of the GOI. Further studies were carried out only with those GOI which had no homologies to EST from nontesticular normal tissues with the exception of placenta and fetal tissue. This evaluation also took into account that the public domain contains wrongly annotated cDNA libraries (Scheurle et al., Cancer Res. 60:4037-4043, 2000) (www.fau.edu/cmbb/publications/cancergenes6.htm).

[0160] The second datamining method utilized was the cDNA xProfiler of the NCBI Cancer Genome Anatomy Project (http://cgap.nci.nih.gov/Tissues/xProfiler) (Hillier et al., Genome Research 6:807-828, 1996; Pennisi, Science 276:1023-1024, 1997). This allows pools of transcriptomes deposited in databases to be related to one another by logical operators. We have defined a pool A to which all expression libraries prepared from testis were assigned, excluding mixed libraries. All cDNA libraries prepared from normal tissues other than testis, ovary or fetal tissue were assigned to pool B. Generally, all cDNA libraries were utilized independently of underlying preparation methods, but only those with a size>1000 were admitted. Pool B was digitally subtracted from pool A by means of the BUT NOT operator. The set of GOI found in this manner was also subjected to eNorthern studies and validated by a literature research.

[0161] This combined datamining includes all of the about 13 000 full-length genes in the public domain and predicts out of these genes a total of 140 genes having potential testis-specific expression. Among the latter were 25 previously known genes of the CT gene class, underlining the efficiency of our strategy.

[0162] All other genes were first evaluated in normal tissues by means of specific RT-PCR. All GOI which had proved to be expressed in nontesticular normal tissues had to be regarded as false-positives and were excluded from further studies. The remaining ones were studied in a large panel of a wide variety of tumor tissues. The antigens depicted below proved here to be ectopically activated in tumor cells.

[0163] RNA Extraction, Preparation of Poly-d (T) Primed eDNA and RT-PCR Analysis

[0164] Total RNA was extracted from native tissue material by using guanidium isothiocyanate as chaotropic agent (Chomczynski & Sacchi, Anal. Biochem. 162:156-9, 1987). After extraction with acidic phenol and precipitation with isopropanol, said RNA was dissolved in DEPC-treated water.

[0165] First strand cDNA synthesis from 2-4 .mu.g of total RNA was carried out in a 20 .mu.l reaction mixture by means of Superscript II (Invitrogen), according to the manufacturer's information. The primer used was a dT(18) oligonucleotide. Integrity and quality of the cDNA were checked by amplification of p53 in a 30 cycle PCR (sense CGTGAGCGCTTCGAGATGTTCCG, antisense CCTAACCAGCTGCCCAACTGTAG, hybridization temperature 67.degree. C.).

[0166] An archive of first strand cDNA was prepared from a number of normal tissues and tumor entities. For expression studies, 0.5 .mu.l of these cDNAs was amplified in a 30 .mu.l reaction mixture, using GOI-specific primers (see below) and 1 U of HotStarTaq DNA polymerase (Qiagen). Each reaction mixture contained 0.3 mM dNTPs, 0.3 .mu.M of each primer and 3 .mu.l of 10.times.reaction buffer. The primers were selected so as to be located in two different exons, and elimination of the interference by contaminating genomic DNA as the reason for false-positive results was confirmed by testing nonreverse-transcribed DNA as template. After 15 minutes at 95.degree. C. to activate the HotStarTaq DNA polymerase, 35 cycles of PCR were carried out (1 min at 94.degree. C., 1 min at the particular hybridization temperature, 2 min at 72.degree. C. and final elongation at 72.degree. C. for 6 min).

[0167] 20 .mu.l of this reaction were fractionated and analyzed on an ethidium bromide-stained agarose gel.

[0168] The following primers were used for expression analysis of the corresponding antigens at the hybridization temperature indicated.

TABLE-US-00001 LDH-C (67.degree. C.) sense TGCCGTAGGCATGGCTTGTGC, antisense CAACATCTGAGACACCATTCC TFT (64.degree. C.) sense TGGATGTCACTCTCATCCTTG, antisense CCATAGTTCCTGTTCTATCTG TSBP (63.degree. C.) sense TCTAGCACTGTCTCGATCAAG, antisense TGTCCTCTTGGTACATCTGAC MS4A12 (66.degree.) sense CTGTGTCAGCATCCAAGGAGC, antisense TTCACCTTTGCCAGCATGTAG BRCO1 (60.degree. C.) sense CTTGCTCTGAGTCATCAGATG, antisense CACAGAATATGAGCCATACAG TPX1 (65.degree. C.) sense TTTTGTCTATGGTGTAGGACC, antisense GGAATGGCAATGATGTTACAG

Preparation of Random Hexamer-Primed cDNA and Quantitative Real Time PCR

[0169] LDHC expression was quantified by means of real time PCR.

[0170] The principle of quantitative real time PCR using the ABI PRISM Sequence Detection System (PE Biosystems, USA) utilizes the 5'-3' exonuclease activity of Taq DNA polymerase for direct and specific detection of PCR products via release of fluorescence reporter dyes. In addition to sense and antisense primers, the PCR employs a doubly fluorescently labeled probe (TaqMan probe) which hybridizes to a sequence of the PCR product. The probe is labeled 5' with a reporter dye (e.g. FAM) and 3' with a quencher dye (e.g. TAMRA). If the probe is intact, the spatial proximity of reporter to quencher suppresses the emission of reporter fluorescence. If the probe hybridizes to the PCR product during the PCR, said probe is cleaved by the 5'-3' exonuclease activity of Taq DNA polymerase and suppression of the reporter fluorescence is removed. The increase in reporter fluorescence as a consequence of the amplification of the target, is measured after each PCR cycle and utilized for quantification. Expression of the target gene is quantified absolutely or relative to expression of a control gene with constant expression in the tissues to be studied. LDHC expression was calculated by means of the .DELTA..DELTA.-C.sub.t method (PE Biosystems, USA), after normalizing the samples to 18s RNA as "housekeeping" gene. The reactions were carried out in duplex mixtures and determined in duplicate. cDNA was synthesized using the High Capacity cDNA Archive Kit (PE Biosystems, USA) and hexamer primers according to the manufacturer's information. In each case 5 .mu.l of the diluted cDNA were used for the PCR in a total volume of 25 .mu.l: sense primer (GGTGTCACTTCTGTGCCTTCCT) 300 nM; antisense primer (CGGCACCAGTTCCAACAATAG) 300 nM; TaqMan probe (CAAAGGTTCTCCAAATGT) 250 nM; sense primer 18s RNA 50 nM; antisense primer 18s RNA 50 nM; 18s RNA sample 250 nM; 12.5 .mu.l TaqMan Universal PCR Master Mix; initial denaturation 95.degree. C. (10 min); 95.degree. C. (15 sec); 60.degree. C. (1 min); 40 cycles. Due to amplification of a 128 bp product beyond the border of exon 1 and exon 2, all LDHC splice variants described were included in the quantification.

Cloning and Sequence Analysis

[0171] Full length genes and gene fragments were cloned by common methods. The sequence was determined by amplifying corresponding antigens by means of the pfu proofreading polymerase (Stratagene). After completion of the PCR, adenosine was ligated by means of HotStarTaq DNA polymerase to the ends of the amplicon in order to clone the fragments into the TOPO-TA vector according to the manufacturer's information. A commercial service carried out the sequencing. The sequences were analyzed by means of common prediction programs and algorithms.

Example 1: Identification of LDH C as a New Tumor Antigen

[0172] LDH C (SEQ ID NO:1) and its translation product (SEQ ID NO:6) have been described as testis-specific isoenzyme of the lactate dehydrogenase family. The sequence has been published in GenBank under accession number NM_017448. The enzyme forms a homotetramer having a molecular weight of 140 kDa (Goldberg, E. et al., Contraception 64(2):93-8, 2001; Cooker et al., Biol. Reprod. 48(6):1309-19, 1993; Gupta, G. S., Crit. Rev. Biochem. Mol. Biol. 34(6):361-85, 1999).

[0173] RT-PCR studies for expression analysis using a primer pair (5'-TGCCGTAGGCATGGCTTGTGC-3', 5'-CAACATCTGAGACACCATTCC-3') which does not cross-amplify the related and ubiquitously expressed isoenzymes LDH A and LDH B and which is based on the LDH C prototype sequence NM_017448 which has previously been described as being testis-specific, confirmed according to the invention the lack of expression in all normal tissues tested, but demonstrated that the stringent transcriptional repression of this antigen in somatic cells has been removed in the case of tumors; cf. Table 1. As has been described classically for CT genes, LDH C is expressed in a number of tumor entities.

TABLE-US-00002 TABLE 1 Expression of LDHC in tumors Tested in Tissue total Positive % Melanoma 16 7 44 Mammary carcinomas 20 7 35 Colorectal tumors 20 3 15 Prostate carcinomas 8 3 38 Bronchial carcinomas 17 8 47 Kidney cell carcinomas 7 4 57 Ovarian carcinomas 7 3 43 Thyroid carcinomas 4 1 25 Cervical carcinomas 6 5 83 Melanoma cell lines 8 5 63 Bronchial carcinoma cell 6 2 33 lines

[0174] The expected size of the amplification product is 824 bp, using the PCR primers mentioned above. According to the invention, however, amplification of multiple additional bands was observed in tumors, but not in testis. Since this is indicative for the presence of alternative splice variants, the complete open reading frame was amplified using LDH-C-specific primers (5'-TAGCGCCTCAACTGTCGTTGG-3', 5'-CAACATCTGAGACACCATTCC-3') and independent full-length clones were sequenced. Alignments with the prototype ORF of the LDH C sequence described (SEQ ID NO:1) and the genomic sequence on chromosome 11 confirm additional splice variants (SEQ ID NO:2-5). The alternative splicing events result in the absence of exon 3 (SEQ ID NO:2), of the two exons 3 and 4 (SEQ ID NO:3), of the exons 3, 6 and 7 (SEQ ID NO:4) or of exon 7 (SEQ ID NO:5) (cf. FIG. 2).

[0175] These new splice variants are generated exclusively in tumors, but not in testis. Alternative splicing causes alterations in the reading frame and results in new possible ORFs encoding the amino acid sequences depicted in SEQ ID NO:7-13 (ORF for SEQ ID NO:7: nucleotide position 59-214 of SEQ ID NO:2 and, respectively, SEQ ID NO:4 ORF for SEQ ID NO:8: nucleotide position 289-939 of SEQ ID NO:2; ORF for SEQ ID NO:9: nucleotide position 59-196 of SEQ ID NO:3; ORF for SEQ ID NO:10: nucleotide position 535-765 of SEQ ID NO:3; ORF for SEQ ID NO:11: nucleotide position 289-618 of SEQ ID NO:4; ORF for SEQ ID NO:12: nucleotide position 497-697 of SEQ ID NO:4; ORF for SEQ ID NO:13: nucleotide position 59-784 of SEQ ID NO:5) (FIG. 2, 3). Apart from premature termination, utilization of alternative start codons is also possible so that the encoded proteins may be truncated both N-terminally and C-terminally.

[0176] While SEQ ID NO:8 and SEQ ID NO:10 represent truncated portions of the prototype protein, the protein sequence of SEQ ID NO:7, SEQ ID NO:9, SEQ ID NO:11, SEQ ID NO:12 and SEQ ID NO:13 are additionally altered and contain only tumor-specific epitopes (printed in bold type in FIG. 3). Peptide regions which could result in tumor-specific epitopes are as follows (the strictly tumor-specific portion produced by frame shifts is underlined):

TABLE-US-00003 SEQ ID NO: 14: (of SEQ ID NO: 7) GAVGMACAISILLKITVYLQTPE SEQ ID NO: 15: (of SEQ ID NO: 9) GAVGMACAISILLKWIF SEQ ID NO: 16: (of SEQ ID NO: 11) GWIIGEHGDSSGIIWNKRRTLSQYPLCLGAEWCLCCEN SEQ ID NO: 17: (of SEQ ID NO: 12) MVGLLENMVILVGLYGIKEELFL SEQ ID NO:18: (of SEQ ID NO: 13) EHWKNIHKQVIQRDYME

[0177] These regions may potentially contain epitopes which can be recognized on MHC I or MHC II molecules by T lymphocytes and which result in a strictly tumor-specific response.

[0178] Not all of the predicted proteins have the catalytic lactate dehydrogenase domain for NADH-dependent metabolization of pyruvate to lactate, which represents the last step of anaerobic glycolysis. This domain would be required for the enzymatic function as lactate dehydrogenase (framed in FIG. 3). Further analyses, for example using algorithms such as TMpred and pSORT (Nakai & Kanehisa, 1992), predict different subcellular localizations for the putative proteins.

[0179] According to the invention, the level of expression was quantified by real time PCR using a specific primer-sample set. The amplicon is present in the junction between exon 1 and exon 2 and thus detects all variants (SEQ ID NO:1-5). These studies too, do not detect any transcripts in normal tissues except testis. They confirm significant levels of expression in tumors (FIG. 4).

[0180] LDHC-specific polyclonal antibodies were produced according to the invention by selecting a peptide from the extreme N-terminal region MSTVKEQLIEKLIEDDENSQ (SEQ ID NO:80). LDHC-specific antibodies were produced in rabbits with the aid of this peptide. Subsequent studies on protein expression confirmed selective LDHC expression in testis and in various tumors. In addition, immunohistological studies in accordance with the invention revealed a distinct colocalization of LDHC with cytochrome C oxidase in mitochondria. This indicates that LDHC plays an important part in the respiratory chain of tumors.

Example 2: Identification of TPTE as a New Tumor Antigen

[0181] The sequences of the TPTE transcript (SEQ ID NO:19) and of its translation product (SEQ ID NO:22) have been published in GenBank under accession number NM_013315 (Walker, S. M. et al., Biochem. J. 360(Pt 2):277-83, 2001; Guipponi M. et al., Hum. Genet. 107(2):127-31, 2000; Chen H. et al., Hum. Genet. 105(5):399-409, 1999). TPTE has been described as a gene coding for a possible transmembrane tyrosinephosphatase, with testis-specific expression located in the pericentromeric region of chromosomes 21, 13, 15, 22 and Y (Chen, H. et al., Hum. Genet. 105:399-409, 1999). Alignment studies in accordance with the invention additionally reveal homologous genomic sequences on chromosomes 3 and 7.

[0182] According to the invention, PCR primers (5'-TGGATGTCACTCTCATCCTTG-3' and 5'-CCATAGTTCCTGTTCTATCTG-3') were generated based on the sequence of TPTE (SEQ ID NO:19) and used for RT-PCR analyses (95.degree. 15 min; 94.degree. 1 min; 63.degree. 1 min; 72.degree. 1 min; 35 cycles) in a number of human tissues. Expression in normal tissues was shown to be limited to testis. As described for the other eCT, TPTE variants were shown according to the invention to be ectopically activated in a number of tumor tissues; cf. Table 2. According to the invention, further TPTE splice variants were identified (SEQ ID NO:20, SEQ ID NO:21, SEQ ID NO:54, SEQ ID NO:55, SEQ ID NO:56, SEQ ID NO:57) which are expressed in testicular tissue and in tumors and which have frame shifts and thus altered sequence regions (FIG. 5).

TABLE-US-00004 TABLE 2 Expression of TPTE in tumors Tested Tissue in total Positive % Melanoma 18 9 50 Mammary carcinomas 20 4 20 Colorectal tumors 20 0 0 Prostate carcinomas 8 3 38 Bronchial carcinomas 23 9 39 Kidney cell carcinomas 7 0 0 Ovarian carcinomas 7 2 29 Thyroid carcinomas 4 0 0 Cervical carcinomas 6 1 17 Melanoma cell lines 8 4 50 Bronchial carcinoma cell 6 2 33 lines Mammalian carcinoma cell 5 4 80 lines

[0183] The TPTE genomic sequence consists of 24 exons (accession number NT_029430). The transcript depicted in SEQ ID NO:19 contains all of these exons. The splice variant depicted in SEQ ID NO:20 is produced by splicing out exon 7. The splice variant depicted in SEQ ID NO:21 shows partial incorporation of an intron downstream of exon 15. As the variants SEQ ID NO:54, SEQ ID NO:55, SEQ ID NO:56, SEQ ID NO:57 indicate, it is alternatively also possible to splice out exons 18, 19, 20 and 21.

[0184] These alternative splicing events result in alterations of the encoded protein, with the reading frame being retained in principle (FIG. 6). For example, the translation product encoded by the sequence depicted in SEQ ID NO:20 (SEQ ID NO:23) has a deletion of 13 amino acids in comparison to the sequence depicted in SEQ ID NO:22. The translation product encoded by the sequence depicted in SEQ ID NO:21 (SEQ ID NO:24) carries an additional insertion in the central region of the molecule and thereby differs from the other variants by 14 amino acids.

[0185] The translation products of the variants SEQ ID NO:54, SEQ ID NO:55, SEQ ID NO:56, SEQ ID NO:57, namely the proteins SEQ ID NO:58, SEQ ID NO:59, SEQ ID NO:60, SEQ ID NO:61, are likewise altered.

[0186] Analyses for predicting the functional domains reveal the presence of a tyrosinephosphatase domain for SEQ ID NO:22, SEQ ID NO:23, SEQ ID NO:24, SEQ ID NO:58, SED ID NO:60 but not for SEQ ID NO:59, SEQ ID NO:61. For all variants, 3-4 transmembrane domains are predicted (FIG. 6).

[0187] Analysis of TPTE antigen expression, using specific antibodies, confirmed selective expression in testis and in a number of different tumors. Colocalization studies moreover revealed that according to the invention TPTE is located together with class I immunoglobulins on the cell surface of tumor cells. Previously, TPTE had been described only as a Golgi-associated protein. Owing to TPTE expression on the cell surface of tumor cells, this tumor antigen is suitable according to the invention as an outstanding target for developing diagnostic and therapeutic monoclonal antibodies. Owing to the predicted membrane topology of TPTE, the extracellulary exposed regions are particularly suitable for this purpose according to the invention. According to the invention, this comprises the peptides FTDSKLYIPLEYRS (SEQ ID NO:81) and FDIKLLRNIPRWT (SEQ ID NO: 82). In addition, TPTE was shown to promote the migration of tumor cells. To this end, tumor cells which had been transfected with TPTE under the control of a eukaryotic promoter and control cells were studied in "Boyden chamber" migration experiments, as to whether they exhibit directed migration. TPTE-transfected cells here had according to the invention markedly (3-fold) increased migration in 4 independent experiments. These functional data indicate that TPTE plays an important part in the metastasizing of tumors. Thus, processes which inhibit according to the invention endogenous TPTE activity in tumor cells, for example by using antisense RNA, different methods of RNA interference (RNAi) by means of expression vectors or retroviruses, and by using small molecules, could result in reduced metastasizing and thus be very important therapeutically. A causal connection between the activity of a phosphatase in tumors and increased migration and increased formation of metastases was established recently for the PTEN tyrosinephosphastase (Iijima and Devreotes Cell 109:599-610, 2002).

Example 3: Identification of TSBP as a New Tumor Antigen

[0188] The electronic cloning method employed according to the invention produced TSBP (SEQ ID NO:29) and the protein derived therefrom (SEQ ID NO:30). The gene has been described previously as being testis-specifically regulated (accession number NM_006781). The gene was predicted to encode a basic protein and to be located on chromosome 6 close to a sequence coding for an MHC complex (C6orf10) (Stammers M. et al., Immunogenetics 51(4-5):373-82, 2000). According to the invention, the previously described sequence was shown to be incorrect. The sequence of the invention is substantially different from the known sequence. According to the invention, 3 different splicing variants were cloned. The differences in the nucleotide sequences of the TSBP variants found according to the invention (SEQ ID NO:31, SEQ ID NO: 32, SEQ ID NO:33) to the known sequence (NM_006781, SEQ ID NO:29) are depicted in FIG. 7 (differences depicted in bold type). They result in frame shifts so that the proteins encoded by the TSBP variants found according to the invention (SEQ ID NO:34, SEQ ID NO:35, SEQ ID NO:36) differ substantially from the previously described protein (SEQ ID NO:30) (FIG. 8).

[0189] It was confirmed according to the invention that this antigen is strictly transcriptionally repressed in normal tissues (PCR primers 5'-TCTAGCACTGTCTCGATCAAG-3' and 5'-TGTCCTCTTGGTACATCTGAC-3'). However, in 25 normal tissues studied, TSBP was expressed, apart from in testis, also in normal lymph node tissue. According to the invention, ectopic activation of TSBP in tumors was also detected, and it therefore qualifies as a tumor marker or tumor-associated antigen (Table 3).

[0190] Although TSBP expression is found in primary tumor tissue, it is not found in permanent cell lines of corresponding tumor entities. Moreover, the gene is in the direct neighborhood of Notch 4 which is specifically expressed in arteries and involved in vascular morphogenesis. These are significant indications of this being a marker for specific endothelial cells. TSBP may therefore serve as a potential marker for tumor endothelia and for neovascular targeting.

[0191] Consequently, the TSBP promoter may be cloned to another genetic product whose selective expression in lymph nodes is desired.

[0192] Analysis of TSBP antigen expression, using specific antibodies, confirmed the selective localization of the protein in testis and lymph nodes and also in melanomas and bronchial carcinomas. In addition, immunohistological studies using GFP-tagged TSBP revealed a distinct perinucleic accumulation.

Example 4: Identification of MS4A12 as a New Tumor Antigen

[0193] MS4A12 (SEQ ID NO:37, accession number NM_017716) and its translation product (SEQ ID NO:38) have been described previously as members of a multigene family related to the B cell-specific antigen CD20, the hematopoietic cell-specific protein HTm4 and the P chain of the high affinity IgE receptor. All family members are characterized by at least four potential transmembrane domains and both the C and the N-terminus are cytoplasmic (Liang Y. et al., Immunogenetics 53(5):357-68, 2001; Liang Y. & Tedder, Genomics 72(2):119-27, 2001). According to the invention, RT-PCR studies on MS4A12 were carried out. The primers were selected based on the published MS4A12 sequence (NM_017716) (sense: CTGTGTCAGCATCCAAGGAGC, antisense: TTCACCTTTGCCAGCATGTAG). In the tissues tested, expression was detected only in testis, colon (6/8) and colorectal carcinomas (colon-Ca's) (16/20) and in colonic metastases (12/15) (FIG. 9).

[0194] The high incidence in colonic metastases makes TSBP an attractive diagnostic and therapeutic target. According to the invention, the predicted extracellular region comprising the protein sequence GVAGQDYWAVLSGKG (SEQ ID NO:83) is particularly suitable for producing monoclonal antibodies and small chemical inhibitors. According to the invention, the intracellular localization of the MS4A12 protein on the cell membrane was also confirmed by fluorescence superposition using plasma membrane markers in confocal immunofluorescence.

TABLE-US-00006 TABLE 4 Expression of MS4A12 in normal tissues and colorectal carcinomas and metastasis Ileum + Colon + Liver - Lung - Lymph nodes - Stomach - Spleen - Adrenal gland - Kidney - Esophagus - Ovary - Rectum + Testis + Thymus - Skin - Mamma - Pancreas - PBMC - PBMC act. - Prostate - Thyroid - Tube - Uterus - Cerebrum - Cerebellum - Colorectal tumors 16/20 Colorectal tumors 12/15 metastases

[0195] Thus, MS4A12 is a cell membrane-located differentiation antigen for normal colon epithelia, which is also expressed in colorectal tumors and metastases.

Example 5: Identification of BRCO1 as a New Tumor Antigen

[0196] BRCO1 and its translation product have not been described previously. The datamining method of the invention produced the EST (expressed sequence tag) AI668620. RT-PCR studies using specific primers (sense: CTTGCTCTGAGTCATCAGATG, antisense: CACAGAATATGAGCCATACAG) were carried for expression analysis. According to the invention, specific expression was found in testicular tissue and additionally in normal mammary gland (Table 5). In all other tissues, this antigen is transcriptionally repressed. It is likewise detected in mammary gland tumors (20 out of 20). BRCO1 is distinctly overexpressed in breast tumors in comparison with expression in normal mammary gland tissue (FIG. 10). Utilizing EST contigs (the following ESTs were incorporated: AW137203, BF327792, BF327797, BE069044, BF330665), more than 1500 bp of this transcript were cloned according to the invention by electronic full-length cloning (SEQ ID NO:39). The sequence maps to chromosome 10p11-12. In the same region, in immediate proximity, the gene for a mammary differentiation antigen, NY-BR-1, has been described previously (NM_052997; Jager, D. et al., Cancer Res. 61(5):2055-61, 2001).

TABLE-US-00007 TABLE 5 Expression of BRCO1 in normal tissues and breast tumors Ileum - Colon - Liver - Lung - Lymph nodes - Stomach - Spleen - Adrenal gland - Kidney - Esophagus - Ovary - Rectum - Testis + Thymus - Skin - Mamma + Pancreas - PBMC - PBMC act. - Prostate - Thyroid - Tube - Uterus - Cerebrum - Cerebellum - Mammary carcinomas ++ (20/20)

[0197] Matched pair (mammary carcinoma and adjacent normal tissue) studies revealed BRCO1 overexpression in 70% of the mammary carcinomas in comparison with the normal tissue.

[0198] Thus, BRCO1 is a new differentiation antigen for normal mammary gland epithelia, which is overexpressed in breast tumors.

Example 6: Identification of TPX1 as a New Tumor Antigen

[0199] The sequence of TPX1 (Acc. No. NM_003296; SEQ ID NO: 40) and of its translation product (SEQ ID NO:41, are known. The antigen has been described previously only as being testis-specific, that is as an element of the outer fibers and of the acrosome of sperms. Previously, an involvement as adhesion molecule in the attachment of sperms to Sertoli cells has been attributed to said antigen (O'Bryan, M. K. et al., Mol. Reprod. Dev. 58(1):116-25, 2001; Maeda, T. et al., Dev. Growth Differ. 41(6):715-22, 1999). The invention reveals, for the first time, aberrant expression of TPX1 in solid tumors (Table 6). Owing to the marked amino acid homology between TPX1 and the neutrophile-specific matrix glycoprotein SGP 28 (Kjeldsen et al., FEBS Lett 380:246-259, 1996), TPX1-specific protein sequences comprising the peptide SREVTTNAQR (SEQ ID NO:84) are suitable according to the invention for preparing diagnostic and therapeutic molecules.

Example 7: Identification of BRCO2 as a New Tumor Genetic Product

[0200] BROC2 and its translation product have not been described previously. The method of the invention produced the ESTs (expressed sequence tag) BE069341, BF330573 and AA601511. RT-PCR studies using specific primers (sense: AGACATGGCTCAGATGTGCAG, antisense: GGAAATTAGCAAGGCTCTCGC) were carried out for expression analysis. According to the invention, specific expression was found in testicular tissue and additionally in normal mammary gland (Table 7). In all other tissues, this genetic product is transciptionally repressed. It is likewise detected in mammary gland tumors. Utilizing EST contigs (the following ESTs were incorporated: BF330573, AL044891 and AA601511), 1300 bp of this transcript were cloned according to the invention by electronic full-length cloning (SEQ ID 62). The sequence maps to chromosome 10p11-12. In the same region, in immediate proximity, the gene for a mammary differentiation genetic product, NY-BR-1, has been described previously (NM_052997; Jager, D. et al., Cancer Res. 61(5):2055-61, 2001), and here the BRCO1 described above under Example 6 is located. Further genetic analyses revealed according to the invention that the sequence listed under SEQ ID NO:62 represents the 3' untranslated region of the NY-BR-1 gene, which has not been described previously.

TABLE-US-00009 TABLE 7 Expression of BRCO2 in normal tissues and breast tumors Tissue Expression Testis + Mamma + Skin - Liver - Prostate - Thymus - Brain - Lung - Lymph nodes - Spleen - Adrenal gland - Ovary - Leukocytes - Colon - Esophagus - Uterus - Skeleton muscle - Epididymis - Bladder - Kidney - Mammary carcinoma +

[0201] BRCO2 is a new differentiation genetic product for normal mammary gland epithelia, which is also expressed in breast tumors.

Example 8: Identification of PCSC as a New Tumor Genetic Product

[0202] PCSC (SEQ ID NO:63) and its translation product have not been described previously. The datamining method of the invention produced the EST (expressed sequence tag) BF064073. RT-PCR studies using specific primers (sense: TCAGGTATTCCCTGCTCTTAC, antisense: TGGGCAATTCTCTCAGGCTTG) were carried out for expression analysis. According to the invention, specific expression was found in normal colon, and additionally in colon carcinomas (Table 5). In all other tissues, this genetic product is transcriptionally repressed. PCSC codes for two putative ORFs (SEQ ID 64 and SEQ ID 65). Sequence analysis of SEQ ID 64 revealed a structural homology to CXC cytokines. In addition, 4 alternative PCSC cDNA fragments were cloned (SEQ ID NO:85-88). In each case, according to the invention, each cDNA contains 3 putative ORFs which code for the polypeptides depicted in SEQ ID NO:89-100.

TABLE-US-00010 TABLE 8 Expression of PCSC in normal tissues and colorectal carcinomas Ileum + Colon + Liver - Lung - Lymph nodes - Stomach - Spleen - Adrenal gland - Kidney - Esophagus - Ovary - Rectum + Testis - Thymus - Skin - Mamma - Pancreas - PBMC - PBMC act. - Prostate - Thyroid - Tube - Uterus - Cerebrum - Cerebellum - Colorectal tumors 19/20 Colorectal tumors 15/15 metastases

[0203] Thus, PCSC is a differentiation antigen for normal colon epithelia which is also expressed in colorectal tumors and in all colon metastases studied. PCSC expression detected in all colorectal metastases according to the invention renders this tumor antigen a very interesting target for prophylaxis and treatment of metastasizing colon tumors.

Example 9: Identification of SGY-1 as a New Tumor Antigen

[0204] The sequences of the SGY-1 transcript (SEQ ID NO:70) and of its translation product (SEQ ID NO:71) have been published in GenBank under accession number AF177398 (Krupnik et al., Gene 238, 301-313, 1999). Soggy-1 has previously been described as a member of the Dickkopf protein family which act as inhibitors and antagonists of the Wnt family of proteins. The Wnt proteins in turn have important functions in embryonic development. Based on the sequence of SGY-1 (SEQ ID NO:70), PCR primers (5'-CTCCTATCCATGATGCTGACG-3' and 5'-CCTGAGGATGTACAGTAAGTG-3') were generated according to the invention and used for RT-PCR analyses (95.degree. 15 min; 94.degree. 1 min; 63.degree. 1 min; 72.degree. 1 min; 35 cycles) in a number of human tissues. Expression in normal tissues was shown to be limited to testis. As described for the other eCT, SGY-1 was shown according to the invention to be ectopically activated in a number of tumor tissues; cf. Table 9.

Example 10: Identification of MORC as a New Tumor Antigen

[0205] The sequences of the MORC transcript (SEQ ID NO:74) and of its translation product (SEQ ID NO:75) have been published in GenBank under the accession number XM_037008 (Inoue et al., Hum Mol Genet. July: 8(7):1201-7, 1999).

[0206] MORC has originally been described as being involved in spermatogenesis. Mutation of this protein in the mouse system results in underdevelopment of the gonads.

[0207] Based on the sequence of MORC (SEQ ID NO:74), PCR primers (5'-CTGAGTATCAGCTACCATCAG-3' and 5'-TCTGTAGTCCTTCACATATCG-3') were generated according to the invention and used for RT-PCR analyses (95.degree. 15 min; 94.degree. 1 min; 63.degree. 1 min; 72.degree. 1 min; 35 cycles) in a number of human tissues. Expression in normal tissues was shown to be limited to testis. As described for the other eCT, MORC was shown according to the invention to be ectopically activated in a number of tumor tissues: cf. Table 10.
