    l(3)neo18 RNAi Under rich nutritional conditions lifespan of l(3)neo18 (alias CG9762) RNAi knockout animals is indistinguishable from wild-type, while upon DR, lifespan extension is diminished in males and females [19804760]. Fly
    CG5389 RNAi RNAi of complex V subunit CG5389 results in increased mean longevity under standard laboratory food conditions (3% yeast) in males. RNAi started from the development results in a mild lifespan increase in both sexes (3-11% in females and 3-8% in males). Post-developmental RNAi and silencing limited to neurons has variable effects with reduction in lifespan of up to 9% [19747824]. Under rich media conditions CG5389 knockdown throughout development and adulthood increases mean lifespan by 26% and abolished the lifespan extension by DR (started in the adulthood) in males. Suppression of CG5389 only during the adulthood either via RNAi by tub-GS or via oligomycin (a specific inhibitor of complex V) feeding prevents an increase in longevity under DR (started in the adulthood) in males [19968629]. Fly -9 to +26
    Sod1 knockdown Sod1 knockdown by RNAi blunts the lifespan extension by a high sugar-low protein diet, but not a low-calorie diet [22672579]. Fly
    Sod2 RNAi RNA interference of Sod2 results in increased oxidative stress and early-onset mortality in young adults [12456885]. Fly
    Akh knockdown Knockdown of the adipokinetic hormone (Akh) by RNAi (with an RU486-inducible and ubiquitously expressing Actin 5C-GS Gal4 strain) does not by itself affect lifespan, but significantly inhibits the 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%). Global Akh knockdown reduces starvation resistance by 24% upon DR, but no significant change upon AL. Also Akh RNAi repressed the DR-dependent increase in cold-stress resistance. Fat body and neuronal-specific inhibition of Akh by using RU486-inducible S(1)106-GS-Gal4 and Elav-GS-Gal4 enhancer traps, respectively, does not reduce lifespan extension upon DR. But, muscle-specific inhibition of Akh using RU486-inducible muscle enhancer trap (Mhc-GS-Gal4) reduces the DR-dependent increase in lifespan. While control exhibit a 47.2% lifespan extension, animals with muscle-specific Akh inhibition fails to result in any increase upon DR (i.e. completely blocked the DR lifespan extension). Muscle-specific Akh inhibition diminishes the increase in triglyceride synthesis and breakdown present normally under DR. A significant reduction in lifespan extension also occurs with a noninducible muscle driver (Mhc-Gal4). Controls on DR exhibit significant higher levels of spontaneous activity compared to Akh RNAi-inhibited animals at all ages. Akh inhibition reduces the protective effect of DR on age-related decline in muscle function/activity [22768842]. Fly
    CG4389 knockdown Muscle specific RNAi knockdown of CG489 which reduces its mRNA levels by 25-35%, significantly reduces the DR-dependent lifespan extension. CG4389 RNAi animals exhibit only 20% increase while controls display an lifespan increase by 123% upon DR [22768842]. Fly
    CG7834 knockdown Muscle specific RNAi knockdown of CG7834 which reduces its mRNA levels by 25-35%, significantly reduces the DR-dependent lifespan extension. CG7834 RNAi animals exhibit only a 14% increase compared to the 55% lifespan-increase in controls upon DR [22768842]. Fly
    Fat-body specific Akh knockdown Fat-body specific Akh RNAi results in increased spontaneous activity and a small but significant increase in lifespan upon AL [22768842]. Fly
    Cbs RNAi Cbs RNAi partially abrogates increased lifespan by DR, but has no effect on fully fed animals. Cbs upregulation is required for increased lifespan under low-nutrient conditions. Response of male flies to DR is muted in comparison with females [21930912]. Fly
    car mutation Loss-of-function mutation in car results in reduction of mean lifespan by 34 - 63% and maximum lifespan by 28 - 29% [17435236]. Fly -34 to -63 -28 to -29
    Sirt6 RNAi Decreased expression of Sirt6 by RNA interference causes lethality during development. Sirt6 silencing in neurons shortens mean lifespan by 20% [17159295]. Fly -20
    Sir2 RNAi Decreased expression of Sir2 and Sir2-like genes in all cells causes lethality during development. Suppression of the Sir2 in neurons decreases the median lifespan by 10-30%, while ubiquitous silencing of the Sir2-like genes shortens lifespan. The effects are server at 28°C that at 25°C [17159295]. Fly -10 to -30
    Sirt2 RNAi Decreased expression of Sirt2 by RNA interference causes lethality during development. Silencing in neurons shortened mean lifespan by 20% [17159295]. Fly -20
    Akt1 RNAi RNA interference of Akt1 in intestinal stem cells, results in impaired regeneration of the intestinal epithelium and a short lifespan. In males and females on mean lifespan is 11.4% and 7.4% lower [20976250]. Fly -11.4 to -7.4
    Aut1 RNAi Aut1 depletion by RNAi form the first day of imaginal stage shortens lifespan by 28% on average in Drosophila and causes morphological behavioural features of premature aging [18219227]. Fly -28
    bsk RNAi RNA interference of bsk in intestinal stem cells, results in short lived mutants with impaired intestinal homeostasis and tissue regeneration. The mean lifespan of males is 16.4% lower and those of female is reduced by 10.2% [20976250]. Fly -10.2 to -16.4
    CG17856 RNAi RNAi of CG17856 results in an increase in mean lifespan of 13-18% in females. In the case of males and post-developmental experiments the results are variable [19747824]. Fly +13 to +18
    CG18809 RNAi RNAi of CG18809 results in a 7-19% increase in mean lifespan of females, while neural RNAi results in an increased mean lifespan of up to 12% in females. For males the results are variable [19747824]. Fly +7 to +19
    CG9172 RNAi RNAi against CG9172 increases mean lifespan in females by up to 4-12% when applied in both development and adulthood, and up to 46% when applied in adult neurons only. For males the effect is variable [19747824]. Fly +4 to +46
    Ilp2 RNAi Ilp2 RNA interference results in a 24% to 47% increase in median lifespan [19005568]. Fly +24 to +47
    Mlp84B RNAi RNA interference of Mlp84B specifically in the heart results in bradycardia and heart rythm abnormalities as well as a shorter mean lifespan in males but not in females [18083727]. Fly
