Both embryonic and adult stem cells are endowed with a superior capacity to prevent the accumulation of genetic lesions, repair them, or avoid their propagation to daughter cells, which would be particularly detrimental to the whole organism. Inducible pluripotent stem cells also display a robust DNA damage response, but the stability of their genome is often conditioned by the mutational history...
Pifithrin-alpha (PFT) is an inhibitor of p53 and is known to protect against a variety of p53-mediated genotoxic agents. In this report, we examined the inhibitory effects of PFT against docosahexaenoic acid (DHA)-induced cytotoxicity in the human hepatocellular carcinoma (HCC) cell line HepG2. PFT significantly abrogated DHA-induced cytotoxicity in wild-type HepG2 cells (normal expression of p53)...
