The protein deacetylase, sirtuin 1, is suggested as a master regulator of exercise-induced beneficial effects. Sirtuin 1 modulates mitochondrial biogenesis, primarily via its ability to deacetylate and activate proliferator-activated receptor-γ coactivator-1α (PGC-1α), interacting with AMPK kinase. Redox cell status can also influence this regulatory axis and together they form an ...
