Lay Description

Inhibitors of the sodium-glucose co-transporter (SGLT2) are FDA-approved for the treatment of type 2 diabetes (T2DM). Their mechanism of action involves lowering of blood glucose concentration secondary to increased glucose excretion of glucose by the kidney. These drugs also improve body weight, blood pressure, and cardiac function. Based on these pleiotropic effects, including its calorie restriction-mimetic properties, the study team hypothesize that SGLT2 drugs will impact several basic aging-related processes, including reductions in oxidative damage to DNA and proteins, advanced glycation end products (AGE) and receptor for AGE (RAGE), cellular senescence, and mitochondrial function.
