Enhancing integrin function by VEGF/neuropilin signaling: implications for tumor biology

Cell Adh Migr. Nov-Dec 2012;6(6):554-60. doi: 10.4161/cam.22419. Epub 2012 Oct 17.

Abstract

This review advances the hypothesis that the ability of integrins to engage their extracellular matrix ligands and signal can be regulated in tumor cells by vascular endothelial growth factor (VEGF), a major angiogenic factor that also has direct effects on the function of tumor cells. More specifically, we will discuss how neuropilins (NRPs), a distinct class of VEGF receptors, enable the function of specific integrins that contribute to tumor initiation and progression.
