Dietary restriction (DR) robustly increases lifespan across taxa. However, in humans, long-term DR is difficult to maintain, leading to the search for compounds that regulate metabolism and increase lifespan without reducing caloric intake. The magnitude of lifespan extension from two such compounds, rapamycin and metformin, remains inconclusive, particularly in vertebrates. Here, we conducted a meta-analysis… Continue reading #Rapamycin, Not #Metformin, Mirrors #Dietary Restriction-Driven #Lifespan Extension in Vertebrates: A Meta-Analysis

Long-lasting geroprotection from brief rapamycin treatment in early adulthood by persistently increased intestinal autophagy
The licensed drug rapamycin has potential to be repurposed for geroprotection. A key challenge is to avoid adverse side effects from continuous dosing. Here we show that geroprotective effects of chronic rapamycin treatment can be obtained with a brief pulse of the drug in early adulthood in female Drosophila and mice. In Drosophila, a brief, early rapamycin treatment… Continue reading Long-lasting geroprotection from brief rapamycin treatment in early adulthood by persistently increased intestinal autophagy
