Death and Dessert: Nutrient Signalling Pathways and Ageing

Curr Opin Cell Biol. 2011 Dec;23(6):738-43. doi: 10.1016/ Epub 2011 Aug 9.


Reduction in nutrient intake without malnutrition can delay ageing and extend healthy life in diverse organisms from yeast to primates. This effect can be recapitulated by genetic or pharmacological dampening of the signal through nutrient signalling pathways, making them a promising target for intervention into human ageing and age-related diseases. Here we review the current knowledge of the interactions between nutrient signalling pathways and ageing, focusing on the findings emerged in the past few years.
