“…Signaling through MET results in cell survival, proliferation, motility, migration, and complex morphogenetic processes (2,7,8). Although MET signaling is essential for embryonic development and tissue repair in adults (2), aberrant signaling through activating MET mutations (3,4,8), MET overexpression (9,10), or dysregulated autocrine expression of HGF and MET in tumor cells (9)(10)(11)(12)(13) contributes to malignant progression and metastasis of cancer cells (2,7,8). High serum HGF levels (14,15), MET overexpression (10), and extensive MET phosphorylation (16) correlate with increasing cancer stage, malignant potential, and poor prognosis.…”
