PKR is not a universal target of tumor suppressor p53 in response to genotoxic stress.

摘要

It has been recently reported that p53 activation can lead to the induction of PKR-eIF2alpha phosphorylation pathway. However, we demonstrate that PKR and eIF2alpha phosphorylation at serine 51 are not downstream of p53 in response to doxorubicin treatment suggesting that PKR is not a universal target of p53 as proposed.
