Potential relevance to dietary restriction and ageing
- Observations
-
Overexpression of Sir2 (alias dSir2) extends lifespan by up to 57% and specifically median lifespan by 40-60%, whereas a decrease in Sir2 activity by mutation blocks the life-extending effect of DR. Sir2 mutation does not reduce lifespan under ad libitum [1284]. Another study also found that whole-body Sir2 knockdown suppressed the life-extending effects of DR; moreover, Sir2 knockdown in the fat body resulted in suppression of life-extension under yeast-restricted conditions but normal lifespan under normal diet [2622].
