Input: Abstract: Inhibition of v3 or v5 integrin function has been reported to suppress neovascularization and tumor growth, suggesting that these integrins are critical modulators of angiogenesis. Here we report that mice lacking 3 integrins or both 3 and 5 integrins not only support tumorigenesis, but have enhanced tumor growth as well. Moreover, the tumors in these integrin-deficient mice display enhanced angiogenesis, strongly suggesting that neither 3 nor 5 integrins are essential for neovascularization. We also observed that angiogenic responses to hypoxia and vascular endothelial growth factor (VEGF) are augmented significantly in the absence of 3 integrins. We found no evidence that the expression or functions of other integrins were altered as a consequence of the 3 deficiency, but we did observe elevated levels of VEGF receptor-2 (also called Flk-1) in 3-null endothelial cells. These data indicate that v3 and v5 integrins are not essential for vascular development or pathological angiogenesis and highlight the need for further evaluation of the mechanisms of action of v-integrin antagonists in anti-angiogenic therapeutics..
