Fig. 1From: Merging perspectives: genotype-directed molecular therapy for hereditary diffuse gastric cancer (HDGC) and E-cadherin–EGFR crosstalkBidirectional E-cadherin/catenin–EGFR cross talk in epithelial biology. Protein–protein interaction with the extracellular cadherin-binding domains of E-cadherin inhibits ligand-mediated activation of EGFR signaling (right); loss of E-cadherin–EGFR interaction leads to increased activation of PI3K, c-Src, and MAPK kinase pathway activation and phosphorylation and destabilization of the E-cadherin/catenin complex (left)Back to article page
