RAS signalling through PI3-Kinase controls cell migration via modulation of Reelin expression

Abstract

Ras signalling through PI3K kinase has an important role in tumour initiation and progression. Here, the authors show that the interaction of Ras with PI3-Kinase p110α and the subsequent activation of Rac-GTPase impairs cell -cell interaction by blocking the downstream Reelin/E-cadherin, thus resulting in cell migration.
