G'rab'bing the microenvironment for invasion

Dev Cell. 2007 Oct;13(4):462-3. doi: 10.1016/j.devcel.2007.09.013.

Abstract

Transformation and metastasis require cell invasion. In this issue of Developmental Cell, Caswell et al. describe a unique mechanism regulating tumor cell invasion. The authors report that an interaction between beta1 integrin and Rab25, a GTPase that has been linked to tumor aggressiveness and metastasis, regulates the recycling of alpha5beta1 integrin to the leading edge of cell pseudopodia.
