Diabetes drug has unexpected, broad implications for healthy aging

LA JOLLA—Metformin is the most commonly prescribed type 2 diabetes drug, yet scientists still do not fully know how it works to control blood sugar levels. In a collaborative effort, researchers from the Salk Institute, The Scripps Research Institute and Weill Cornell Medical College have used a novel technology to investigate why it functions so well. The findings, which identified a surprising number of biochemical “switches” for various cellular processes, could also explain why metformin has been shown to extend health span and life span in recent studies. The work was published in Cell Reports on December 3, 2019.
