The Mesenchymal Epithelial Transition (MET) receptor belongs to a family of Receptor tyrosine kinases (RTKs). The MET proto-oncogene is located on chromosome 7q21–31 and encodes the receptor tyrosine kinase C-Met. It is a 190 kD glycoprotein heterodimer made up of an extracellular α-chain which is linked by a disulphide bond to a transmembrane β-chain. c-Met is initially synthesised as a 170 kD single polypeptide as precursor that is proteolytically cleaved to form the α-chain and the β-chain. TPR-MET oncogenic fusion protein from human osteosarcoma tumor cells was first discovered in 1984. c-Met is a hepatocyte growth factor (HGF) receptor. The initiation of MET signaling begins with the binding of HGF to the MET receptor at cell membrane that causes C-Met dimerization. Subsequent activation is through a process of trans-phosphorylation of the two tyrosine residues in the catalytical regions Y1234 and Y1235, followed by trans-phosphorylation of two docking tyrosines (Y1349 and Y1356). It enables MET to bind to multiple substrates and activate a variety of signaling pathways, such as MAPK, PI3K-AKT cascades, STAT and NF-κB signaling pathways. This is responsible for driving proliferation, cell survival, migration and invasiveness. c-Met is overexpressed in different human tumors, such as thyroid, gastric, pancreatic, breast, cervical and prostate cancers. Increasing evidence indicated that MET may be a common mechanism of resistance to anticancer treatment such as approved EGFR and VEGFR inhibitors, anti-HER2 therapies and a BRAF inhibitor. Hence, the HGF-MET axis has been targeted in solid tumors to overcome the drug resistance.Product Details
