In the mid-1970s, Harold Varmus and Michael Bishop began the hunting for cancer genes in the cell genome. They provided evidence that the viral v-Src gene from avian sarcoma virus was taken up by the virus from host cells and incorporated in its genome. The v-Src was transforming since it encoded for a mutated tyrosine kinase protein. Like v-Src, oncogenes are mutant-activated versions of normal cellular genes, called “proto-oncogenes.” Harold Varmus and Michael Bishop’s theory of carcinogenesis explained how chemicals, X-rays, or other DNA injuries activated such endogenous proto-oncogenes, thus initiating cancer. The MET proto-oncogene was originally identified in 1984 in George Vande Woude’s lab, after a shiny decade of discoveries of cancer-causing genes. The treatment of a human osteogenic sarcoma cell line with a chemical carcinogen induced a chromosomal translocation of the TPR (translocated promoter...
