Scientists at the University of Virginia have discovered an anti-aging mechanism mediated by an enzyme that metabolizes alcohol. Alcohol dehydrogenase, which in Caenorhabditis elegans and yeast replaces the rejuvenating effect of autophagy, would reduce age-associated glycerol levels, also promoting longevity in mice and humans.
Using a mix of clinical and animal studies, researchers at Yale University have identified an enzyme whose decreased activity appears to be behind some of the beneficial effects of caloric restriction. They published their work in the February 11, 2022, issue of Science.
