CYR61, a product of a growth factor-inducible immediate early gene, promotes angiogenesis and tumor growth

Abstract excerpt

CYR61 is a secreted, cysteine-rich, heparin-binding protein encoded by a growth factor-inducible immediate-early gene. Acting as an extracellular, matrix-associated signaling molecule, CYR61 promotes the adhesion of endothelial cells through interaction with the integrin alphaVbeta3 and augments growth factor-induced DNA synthesis in the same cell type. In this study, we show that purified CYR61 stimulates...
