Integrin alpha v beta 3 antagonists promote tumor regression by inducing apoptosis of angiogenic blood vessels.
摘要:
A single intravascular injection of a cyclic peptide or monoclonal antibody antagonist of integrin α v β 3 disrupts ongoing angiogenesis on the chick chorioallantoic membrane (CAM). This leads to the rapid regression of histologically distinct human tumors transplanted onto the CAM. Induction of angiogenesis by a tumor or cytokine promotes vascular cell entry into the cell cycle and expression of integrin α v β 3 . After angiogenesis is initiated, antagonists of this integrin induce apoptosis of the proliferative angiogenic vascular cells, eaving preexisting quiescent blood vessels unaffected. We demonstrate therefore that ligation of integrin α v β 3 is required for the survival and maturation of newly forming blood vessels, an event essential for the proliferation of tumors.
