Oncogenic Mutants of RON and MET Receptor Tyrosine Kinases Cause Activation of the β-Catenin Pathway

Abstract excerpt

beta-Catenin is an oncogenic protein involved in regulation of cell-cell adhesion and gene expression. Accumulation of cellular beta-catenin occurs in many types of human cancers. Four mechanisms are known to cause increases in beta-catenin: mutations of beta-catenin, adenomatous polyposis coli, or axin genes and activation of Wnt signaling. We report a new cause of beta-catenin accumulation involving oncogenic...
