Live longer on MARS: a yeast paradigm of mitochondrial adaptive ROS signaling in aging

Abstract

Adaptive responses to stress, including hormesis, have been implicated in longevity, but their mechanisms and out comes are not fully understood. Here, I briefly summarize a longevity mechanism elucidated in the budding yeast chronological lifespan model by which Mitochondrial Adaptive ROS Signaling (MARS) promotes beneficial epigenetic and metabolic remodeling. The potential relevance of MARS to the human disease Ataxia-Telangiectasia and as a potential anti-aging target is discussed.
