Hepatocyte growth factor (HGF) is the native peptide ligand of the MET receptor and aberrant HGF/MET activation drives oncogenic pathways involved in the development and progression of several human cancers, including renal, gastrointestinal, lung, and breast carcinomas, as well as glioblastoma multiforme (GBM) (26, 27). This evidence concerns the gene MET and glioblastoma.
