| Research Abstract |
We identified membrane protein p130 as a novel receptor for angiostatin (AS). Extracellular region of p130 including vWF-like domains binds AS. AS inhibited VEGF-induced NO production, COX-2 expression in vascular endothelial cells and migration of endothelial cells. We found that p130 might mediate such effects of AS. Our data suggest that AS impairs HSP90 association with eNOS, and that AS abrogates JNK activation. In addition, p130 forms a complex with VE-cadherin and beta-catenin in endothelial cells.
