Housing density does not influence the longevity effect of calorie restriction.

Calorie Restriction, Longevity and Cognitive Function

Sir2 mediates longevity in the fly through a pathway related to calorie restriction.

Calorie restriction can extend life span in a variety of species including mammals, flies, nematodes, and yeast. Despite the importance of this nearly universal effect, little is understood about the molecular mechanisms that mediate the life-span-extending effect of calorie restriction in metazoans. Sir2 is known to be involved in life span determination and calorie restriction in yeast mother...

The Benefits of Calorie Restriction and Calorie Restriction Mimetics as Related to the Eye.

The effects of calorie restriction without malnutrition seem to possess many beneficial effects in numerous disease states. Recently, studies related to calorie restriction mimetics that biochemically mimic the effects of calorie restriction are also becoming increasingly popular. Both calorie restriction and calorie restriction mimetics trigger an adaptive response reminiscent of mild-stress o...

Lifespan extension by calorie restriction relies on the Sty1 MAP kinase stress pathway.

Either calorie restriction, loss-of-function of the nutrient-dependent PKA or TOR/SCH9 pathways, or activation of stress defences improves longevity in different eukaryotes. However, the molecular links between glucose depletion, nutrient-dependent pathways and stress responses are unknown. Here, we show that either calorie restriction or inactivation of nutrient-dependent pathways induces life...

Aging, adiposity, and calorie restriction.

CONTEXT Excessive calorie intake and subsequent obesity increases the risk of developing chronic disease and decreases life expectancy. In rodent models, calorie restriction with adequate nutrient intake decreases the risk of developing chronic disease and extends maximum life span. OBJECTIVE To evaluate the physiological and clinical implications of calorie restriction with adequate nutrient...
