P53 alone or both ARF and p53 conditional knockout MEFs were transduced with Ad-CMV-Cre (Vector Biolabs) for 3 days, in order to undergo Cre-mediated deletion of the floxed p53 or ARF allele. The elimination of p53 or ... WebThe ARF tumor suppressor is a nucleolar protein that activates p53-dependent checkpoints by binding Mdm2, a p53 antagonist. Despite persuasive evidence that ARF can bind and inactivate Mdm2 in the nucleoplasm, the prevailing view is that ARF exerts its growth-inhibitory activities from within the nucleolus.
