20110065640 | ANTI-INVASIVE AND ANTI-ANGIOGENIC COMPOSITIONS - A peptide compound having the sequence Lys-Pro-Ser-Ser-Pro-Pro-Glu-Glu [SEQ ID NO:2] or a substitution variant, addition variant or other chemical derivative thereof inhibits cell invasion, endothelial tube formation or angiogenesis in vitro. A number of substitution variants and addition variants of this peptide, preferably capped at the N- and C-termini, as well as peptidomimetic derivates, are useful for treating diseases and conditions mediated by undesired and uncontrolled cell invasion and/or angiogenesis. Pharmaceutical compositions comprising the above peptides and derivatives are administered to subjects in need of such treatment in a dosage sufficient to inhibit invasion and/or angiogenesis. The disclosed compositions and methods are particularly useful for suppressing the growth and metastasis of tumors. | 03-17-2011 |
20110053864 | Compositions and methods for modulation of cell migration - A peptide includes SEQ ID NO:3, substitution and addition variants thereof which maintain the ability to activate CD44. A complex includes this peptide or an Å6 polypeptide with a CD44 polypeptide. An isolated polypeptide includes the Link region sequence of human CD44, functionally active fragments thereof, substitution variants, and addition variants. A method of treating a disease characterized by aberrant cell migration and/or invasion includes administering to a subject an effective amount of the peptide of SEQ ID NO:3 or an Å6 polypeptide to bind to a CD44 polypeptide and modulate signal transduction activity for a sufficient period of time to treat the disease. Other methods include using the peptide of SEQ ID NO:3 or an Å6 polypeptide for diagnosing, identifying a subpopulation of subjects responsive to treatment, and screening for compounds that bind a CD44 polypeptide. | 03-03-2011 |
