Cross communication between the Met receptor tyrosine kinase and the epidermal growth factor receptor ( EGFR ) has been proposed to involve direct association of both receptors and EGFR kinase dependent phosphorylation . ^^^ Whereas specific inhibition of the EGFR kinase activity blocked EGF but not GPCR agonist induced Met receptor transactivation , it was abrogated in the presence of a reducing agent or treatment of cells with a NADPH oxidase inhibitor . ^^^ Our results provide a new molecular explanation for cell surface receptor cross talk involving the Met receptor and thereby link the wide diversity of GPCRs and the EGFR to the oncogenic potential of Met signaling in human carcinoma cells . . ^^^ Reactive oxygen species mediate Met receptor transactivation by G protein coupled receptors and the epidermal growth factor receptor in human carcinoma cells . ^^^
