WebComplete inhibition of mTORC1 is required to suppress liver cancer development induced by AKT and Ras proto-oncogenes in mice. The mTORC1 effectors, RPS6 and eIF4E, play distinct roles and are both necessary for AKT/Ras hepatocarcinogenesis. These new findings might open the way for innovative therapies against human HCC.

WebOne of the genetic changes induced by retroviruses is the insertion of oncogenes, genetic sequences that are capable of transforming normal cells into cancer cells. Since most viruses have fewer than a dozen genes, compared to ca. 30,000 in the DNA of human cells, studying viruses greatly simplified the search for cancer-causing genes. WebThe p53 tumor suppressor (TP53) also has recurrent synonymous mutations, but, in contrast to those in oncogenes, these are adjacent to splice sites and inactivate them. We estimate that between one in two and one in five silent mutations in oncogenes have been selected, equating to ∼6%-8% of all selected single-nucleotide changes in these genes.
