Vasostatin, the 1–180 amino acids NH2 domain of calreticulin, inhibits endothelial cell proliferation, angiogenesis, and tumor growth,but the mechanisms underlying these effects are unclear. We show that endothelial cells express the extracellular matrix protein laminin, including chains α5 and γ1 and that vasostatin specifically binds to laminin. When added to endothelial cell cultures, vasostatin specifically inhibits endothelial cell attachment to laminin and by this mechanism, can reduce subsequent endothelial cell growth induced by basic fibroblast growth factor. As an angiogenesis inhibitor that specifically disrupts endothelial cell attachment to components of the extracellular matrix, vasostatin has a unique potential as a cancer therapeutic.
