MET also regulates tumour cell migration, invasion and metastasis.25, 28 Signalling molecules activated by MET promote tumour metastasis by changing the expression of proteins involved in cytoskeletal rearrangements (cadherins, Arp2/3, N‐WASP) and cell adhesion (paxillin, integrins and focal adhesion kinase).29, 30, 31. This evidence concerns the gene CDH17 and neoplasm.
