20080229438 | Process of making transgenic mammals that produce exogenous proteins in milk and transgenic mammals produced thereby - The invention relates to a method of producing a protein of interest, comprising making a non-human transgenic mammal that produces said protein in its milk, obtaining said milk from the non-human transgenic mammal and purifying said protein of interest from the milk. Transgenic bovine animals were generated, which are able to produce human growth hormone in mammary glands. The method involves cloning of a genetic construct encoding hGH gene and beta casein promoter conveniently in an expression vector. It also includes transfection procedures into fetal bovine somatic cells, generally fibroblasts, and the nuclear transfer into enucleated bovine oocytes, generating thus transgenic embryos. The method also includes other procedures to generate transgenic embryos for the further expansion of the transgenic herd, such as the subcloning of transgenic female bovines, the superovulation of transgenic cows and their insemination with semen from a non-transgenic or a transgenic male bovine, and the superovulation of non-transgenic cows and their insemination with semen from a transgenic male bovine. Afterwards, transgenic embryos give rise to transgenic cattle that produce human growth hormone in huge amounts in their milk, from which the hormone is completely purified and analysed to fulfill all the requirements for the manufacture of a pure biopharmaceutical product. | 09-18-2008 |

20110016548 | CONTROL OF ENDOGENOUS DNMT1 GENE EXPRESSION BY EXOGENOUS BINARY REGULATORY SYSTEMS - Provided are methods for controlling endogenous gene expression comprising control of the DNA methyltransferase (Dnmt1) for modulation of DNA methylation and epigenetic mechanisms. Provided are transcriptional regulatory systems involving multiple (e.g., three) exogenous binary systems, lacI, tetR and Gal4, for reversible up/down regulation of endogenous target genes Provided are lac operator and repressor modifications for improved repression relative to wild type (WT) lac and tet systems. Provided are endogenous Dnmt1 promoter modifications, comprising targeted lac operator sequences that do not significantly alter promoter activity absent repressors, yet show substantially reduced expression of the targeted allele upon lac repressor introduction. The lacO targeted Dnmt1 allele is introducible into the mouse germline, to provide a respective upregulatable transcriptional control system in vivo (e.g., two binary systems, tet operator/tetVP16 and Gal4 binding sequence/Gal4VP16, and ES cell gene targeting experiments are conducted with a Dnmt1 promoter construct combining all three cis elements. | 01-20-2011 |

In certain embodiments, the method may include inserting a DNA sequence coding for at least a portion of a spider silk fibroin polypeptide, or an analog of a spider silk fibroin polypeptide, positioned between at least a portion of the 5′ and 3′ ends of a silkworm fibroin gene to generate a fusion gene construct having a sequence that encodes for a polypeptide comprising both spider silk fibroin and silkworm silk fibroin sequences. In certain embodiments, the fused gene is able to replace a native gene present in the silkworm such that the transformed silkworm expresses a polypeptide comprising a spider silk fibroin polypeptide, or an analog thereof, and expresses significantly less of the native silkworm silk. | 12-31-2015 |
