Research Abstract

Cancer progression and metastasis depend on recruitment of new blood vessels and are characterized by oncogene-driven tumor expression of pro-angiogenic proteins. Most pro-angiogenic factors are soluble endogenous proteins and their receptors are displayed on the surface of endothelial cells. Inhibition of tumor angiogenesis suppresses experimental tumor growth, and is considered a promising new therapeutic approach to treat human cancer. However, clinical application of anti-angiogenesis therapy for suppression of tumor progression would theoretically require long-term administration of angiogenesis inhibitors, but most of them entering clinical trials are rather large molecular weight protein and/or require intravenous administration. We have previously demonstrated that an anti-angiogenesis inhibitor, endostatin, markedly down regulates a variety of growth-, migration-, and angiogenesis-associated genes in exponentially growing human and rat microvascular endothelial cells. In the present study, we searched for compounds and peptides eliciting such anti-angiogenesis molecular signals in endothelial cells in an attempt to identify new therapeutic agents for human tumors. The results demonstrate that three ansamycin antibiotics and a fragment of vasoactive peptide induced antiangiogenesis signals similar to endostatin and that the former suppressed progression of human cancer xenografts as well.
