Agonizing integrin antagonists?

Cancer Cell. 2009 May 5;15(5):359-61. doi: 10.1016/j.ccr.2009.04.005.

Abstract

A recent study published in Nature Medicine reports that low-dose treatment with RGD-mimetic integrin inhibitors may paradoxically enhance angiogenesis and tumor growth. This work implies that delivery of these agents should be redesigned in order to avoid nanomolar plasma concentrations and to improve their efficacy to treat human cancers.
