Potential relevance to dietary restriction and ageing

Observations

Knockdown of Akh by RNAi does not by itself affect lifespan, but significantly inhibits DR-dependent increase in lifespan across a range of yeast concentrations in both females and males. While control females and males exhibit a 113%/22% increase in lifespan under DR, upon Akh inhibition there was a significant reduction in lifespan extension with DR (52%/5%). Besides, muscle-specific inhibition of Akh reduces the DR-dependent increase in lifespan. Akh inhibition also reduces the protective effect of DR on age-related decline in muscle function/activity. Overexpression of Akh enhances fat metabolism, spontaneous activity (148% on ad lib and 154% on DR), and lifespan on ad lib (33%). However, despite an increase in movement under DR, lifespan is not increased under a restricted diet [2597].
