c-Met, also known as HGFR (hepatocyte growth factor receptor), is a receptor protein tyrosine kinase encoded by the gene MET. Upon binding its ligand HGF (hepatocyte growth factor), c-Met activates multiple cellular processes including proliferation, adhesion and angiogenesis. Importantly, many studies report that c-Met is overexpressed in various carcinomas, suggesting that targeting HGF/c-Met signaling could be a promising target for cancer treatment.
