P14ARF: The absence that makes the difference

Risultato della ricerca: Article

Abstract

P14ARF is a tumor suppressor encoded by the CDKN2a locus that is frequently inactivated in human tumors. P14ARF protein quenches oncogene stimuli by inhibiting cell cycle progression and inducing apoptosis. P14ARF functions can be played through interactions with several proteins. However, the majority of its activities are notoriously mediated by the p53 protein. Interestingly, recent studies suggest a new role of p14ARF in the maintenance of chromosome stability. Here, we deepened this new facet of p14ARF which we believe is relevant to its tumor suppressive role in the cell. To this aim, we generated a monoclonal HCT116 cell line expressing the p14ARF cDNA cloned in the piggyback vector and then induced aneuploidy by treating HCT116 cells with the CENP‐E inhibitor GSK923295. P14ARF ectopic re‐expression restored the near‐diploid phenotype of HCT116 cells, confirming that p14ARF counteracts aneuploid cell generation/proliferation.
