No apparent p53 activation in CRISPR-engineered gene-edited rabbits.

ABSTRACT: Clustered regularly interspaced short palindromic repeats-CRISPR-associated 9 (CRISPR-Cas9) and base editors (BEs) are revolutionary gene-editing technology that has been widely utilized in biology, biotechnology and medicine. However, recent reports show that CRISPR-Cas9-mediated genome editing can induce a p53-mediated stress response and cell cycle arrest in human cells, while not illustrated in gene-editing animals. In the study, to verify whether there is a phenomenon of p53 activation, by analysing nine gene-edited rabbits using CRISPR-Cas9 and BEs, we provide the first evidence that no apparent p53 expression changes in those rabbits generated by Cas9 or BE-edited, suggesting that p53 may not need to consider for application in gene-edited animals.
