  • Patent number: 7645452
    Abstract: This invention relates to a gene encoding RTVP that has been shown to be up-regulated by p53 using differential display-PCR and subsequently by co-transfection studies. RTVP-1 mRNA is abundant in normal mouse and human prostatic epithelial cells and primary tumors, but is significantly down regulated in metastatic mouse and human prostate cancer. In prostate cancer cells overexpression of the mouse RTVP-1 gene (mRTVP-1) induced apoptosis that was accompanied by increased caspase 8, 9 and 3 activities. mRTVP-1-stimulated apoptosis was also associated with increased levels of bax, bad and activated BID; reduced levels of bcl-2 and bcl-XL; and cytosolic cytochrome c accumulation. Adenoviral-vector-mediated mRTVP-1 expression lead to potent growth suppression and antimetastatic activities in an orthotopic mouse model of prostate cancer in vivo. These therapeutic activities were associated with anti-angiogenic effects and importantly a local and systemic immune response.
