title: Src/FAK-mediated regulation of E-cadherin as a mechanism for controlling collective cell movement: insights from in vivo imaging.
abstract: Recent advances in confocal and multi-photon microscopy, together with fluorescent probe development, have enabled cancer biology studies to go beyond the culture dish and interrogate cancer-associated processes in the complex in vivo environment. Regulation of the tumor suppressor protein E-cadherin plays an important role in cancer development and progression and may contribute to the decision between 'single cell' and 'collective invasion' in vivo. Mounting evidence from in vitro and in vivo experiments places the two non-receptor protein tyrosine kinases Src and Focal Adhesion Kinase, at the heart of E-cadherin regulation, and the crosstalk between integrins and cadherins. Here we discuss recent insights, attained using high resolution fluorescent in vivo imaging, into the regulation of E-cadherin and collective invasion. We focus on the regulatory crosstalk between the Src/FAK signaling axis and E-cadherin in vivo.
