CRISPR–Cas9 genome editing induces a p53-mediated DNA damage response Inhibition of p53 prevents the damage response and increases the rate of homologous recombination… In the 1990’s, Abcam researchers discovered the cell death gene. Now see: Mechanisms of Recombination conference See also: P53 toxicity is a hurdle to CRISPR/CAS9 screening and engineering in human pluripotent stem cells We demonstrated the toxic response is tp53-dependent and the toxic effect of tp53 severely reduces the efficiency of precise genome-engineering in hPSCs. Reported as:…
