Down-regulation of LRIG2 expression by RNA interference inhibits glioblastoma cell (GL15) growth, causes cell cycle redistribution, increases cell apoptosis and enhances cell adhesion and invasion in vitro

Abstract excerpt

The leucine-rich and immunoglobulin-like domains (LRIG) gene family contains LRIG1, 2 and 3. LRIG1 is a negative regulator of EGFR, but little is known about the function of LRIG2. To determine the role of LRIG2 in the progression of glioma, we performed RNA interference-mediated knockdown of LRIG2 in a human glioma cell line (GL15). Downregulation of LRIG2 expression resulted in: rapid EGF-mediated loss of EGFR;...
