Oxidative stress can lead to cellular senescence, in a p53-dependent pathway. Bach1, a transcription factor that regulates the response to oxidative stress, is now shown to inhibit senescence induced by high oxygen concentrations or by Ras. Bach1 is recruited to a subset of p53 target genes and contributed to impeding p53 action by promoting histone deacetylation.
