Anti-Angiogenic Gene Therapy of Prostate Cancer with Lentiviral Vectors
Abstract
Tumor progression induces the growth of endothelial cells by releasing angiogenic factors. This is accompanied by down-regulation of local tissue inhibitors of endothelian cell proliferation such as angiostatin and endostatin. Both proteins target normal endothelial cells and effectively regress large tumors in animals. However, animal studies demonstrate that an effective treatment requires long-&term administration of angiogenesis inhibitors. Thus, delivery of angiogenesis inhibitor genes to tumor sites should increase local concentration of these proteins, leading to the retardation of tumor progression and metastasis. During the past fiscal year, we have established stable human prostate cancer cell lines derived from PC3 cells transduced with HIV7/endo, HIV7/angio or both together.
