No Mitochondrial Pain, No Longevity Gain

Oxidative stress can motivate cells to live according to the Nietzschean sentiment that goes, “What does not kill us makes us stronger.” Cells, after a brief oxidant challenge, may react by pumping up their production of antioxidants, developing an enhanced antioxidant capacity, and becoming more resistant to subsequent oxidant challenges. These cellular responses, which were recently investigated by Salk Institute scientists, suggest that short-term stress may lead to long-term adap
