Hepatocyte growth factor receptor (HGF receptor) [5] [6] is a protein that in humans is encoded by the MET gene.The protein possesses tyrosine kinase activity. [7] The primary single chain precursor protein is post-translationally cleaved to produce the alpha and beta subunits, which are disulfide linked to form the mature receptor.
Hepatocyte growth factor has been shown to interact with the protein product of the c-Met oncogene, identified as the HGF receptor . [ 6 ] [ 34 ] [ 35 ] Both overexpression of the Met/HGFR receptor protein and autocrine activation of Met/HGFR by simultaneous expression of the hepatocyte growth factor ligand have been implicated in oncogenesis.
[2] [3] The resulting 65 kDa cytoplasmic Tpr-Met oncoprotein forms a dimer mediated through the Tpr leucine zipper. [4] The Tpr-Met fusion protein lacks the extracellular, transmembrane and juxtamembrane domains of c-Met receptor, and has gained the Tpr dimerization motif, which allows constitutive and ligand-independent activation of the kinase.
Hepatocyte growth factor (HGF) stimulates the tyrosine kinase activity of the receptor encoded by the proto-oncogene c-MET. Oncogene, 6(4), 501-504. Michalopoulos, G. K. (1990).
Type 1 PRCC is caused by a genetic mutation or a gain in chromosome 7 where the MET gene is positioned, resulting in the promotion of oncogenic pathways in renal epithelial cells. [6] Typically, the MET gene is upregulated for renal tissue repair and regeneration by encoding the receptor tyrosine kinase c-MET of hepatocyte growth factor. [6]

A proto-oncogene is a normal gene that could become an oncogene due to mutations or increased expression. Proto-oncogenes code for proteins that help to regulate the cell growth and differentiation. Proto-oncogenes are often involved in signal transduction and execution of mitogenic signals, usually through their protein products.
[39] [38] Hypomethylation of a specific L1 located in the MET onco gene is associated with bladder cancer tumorogenesis, [40] Shift work sleep disorder [41] is associated with increased cancer risk because light exposure at night reduces melatonin, a hormone that has been shown to reduce L1-induced genome instability.
