Calorie restriction has been known formany decades to extend the life span of rodents. Since the more recent discovery that a long-term reduction in nutrient intake also extends life span in nearly every invertebrate model organism used for aging research, the mechanisms behind the longevity benefits of this intervention have been under intense scrutiny. While models have been developed in yeas...
Cyclic adenosine monophosphate (cAMP) plays an important role in many biological processes as a second messenger, and cAMP treatment has been reported to extend the lifespan of wild-type Drosophila melanogaster. Our study showed that exogenous cAMP improved ageing-related phenotypes by increasing the protein level of Sirtuins, which prevented metabolic disorders to mimic the effect of calorie r...
Dietary supplementation with resveratrol may produce calorie restriction-like effects on metabolic and longevity endpoints in mice. In this study, we sought to determine whether resveratrol treatment elicited other hallmark changes associated with calorie restriction, namely bradycardia and decreased body temperature. We found that during short-term treatment, wild-type mice on a calorie-restri...
comes “supersized,” the notion that less is more may seem terribly outof-date. But when it comes to calories, eating fewer may very well turn out to be a prescription for a longer—and healthier—life. The topic of calorie restriction has gotten a lot of attention recently in consumer publications and scientific journals alike. However, the theory that eating fewer calories may promote longevity ...
We investigated the correlations between the reduction in body weight (BW) induced by calorie restriction and reductions in blood pressure (BP) and improvement in metabolic disorders in overweight women with essential hypertension. After eating a standard diet (diet-I) for 2 weeks, women in the calorie-restricted group (n = 25) received a low calorie diet for 2 weeks, and then standard diet-II ...
Calorie restriction (CR) increases lifespan in organisms ranging from budding yeast through mammals. Mitochondrial adaptation represents a key component of the response to CR. Molecular mechanisms underlying this adaptation are largely unknown. Here we show that lysine acetylation of mitochondrial proteins is altered during CR in a tissue-specific fashion. Via large-scale mass spectrometry scre...
