  "textContent": "Researchers from the German Institute of Human Nutrition Potsdam-Rehbruecke (DIfE) and other partner institutions of the German Center for Diabetes Research (DZD) have now identified a previously unknown function of the PICALM protein in skeletal muscle: The protein responds sensitively to physical activity and intermittent fasting. It also plays a decisive role in the formation of new muscle fibers.",
