Antioxidant treatment partially restored lifespan in the male dOpa1 mutants, but had no effects in the females.
Remarkably, and consistent with previous results, the loss of rde-1 completely restored lifespan declines associated with adr-1; adr-2 loss-of-function (Figure 6b).
We further demonstrate that inactivation of the argonaute gene, rde-1, a critical regulator of RNA interference, completely restores lifespan to normal levels in the context of adr-1 and adr-2 loss of function.
For example, although daughters of very old mother cells have a shorter lifespan, the granddaughters restored lifespan to that observed in the daughters of young mothers (Kennedy et al., 1994).
In the present study, hyperoxia abolished the lifespan extension effect of resveratrol seen under normoxic conditions and failed to act as a compensatory agent in restoring lifespan to previous lengths seen in ambient oxygen.
As expected, the wild-type chico construct was able to fully restore the lifespan of chico/+ to that of wild-type flies.
InR mutants are long-lived, and JHA treatment restores lifespan toward that of wildtype flies.
The deletion of FOB1, a gene required for blocking rDNA replication, suppresses rDNA recombination and ERC formation, extends lifespan in wild-type cells, and restores lifespan in sir2 mutant cells (Defossez et al., 1999).
βHB supplementation to the glucose-containing media partially restored the lifespan, resulting in a lifespan reduction of only 21% compared to the non-glucose treated controls.
First, transgenic expression of tph-1 in ADF or NSM restored the lifespan as a function of food availability.
