Met

Met, the hepatocyte growth factor receptor, is a receptor tyrosine kinase that integrates growth, survival, migration, and tissue-remodelling cues during morphogenesis, wound repair, organ homeostasis, and cancer metastasis[1]. Mechanistically, HGF binding activates c-Met and downstream signaling programs linked to proliferation, motility, invasion, and survival[2]. In disease models, aberrant MET activation supports tumor growth and metastatic progression, making HGF/MET signaling a practical axis for cancer biology and drug-response studies[3]. Compared with the related HGF isoform NK1, full-length HGF activates c-Met through an asymmetric complex, whereas NK1 forms a symmetric c-Met signaling complex[4]. For experimental applications, MET inhibitors and HGF/MET-blocking agents provide tools to test kinase-dependent signaling, invasion, and therapeutic vulnerability in MET-driven models[5].
