We reveal a novel pro-survival role for mammalian p38α in response to H2O2 which involves an up-regulation of antioxidant defenses. response allows WT cells to maintain an efficient activation of the mTOR/p70S6K pathway. Accordingly the loss of p38α leads to ROS accumulation in response to H2O2 which causes cell death and inactivation of mTOR/p70S6K signaling.… Continue reading We reveal a novel pro-survival role for mammalian p38α in response
