    acs-5 RNAi RNA interference of acs-5 increases mean lifespan by 52% [17608836]. Worm +52
    act-4 RNAi Knockdown of act-4 started after the animal reached the late L4 stage decreases mean lifespan by 28% [22103665]. Worm
    Adcy5 knockout Adcy5 knockout mice are to cardiac stress and have an increased median lifespan of 30% as well as an increased maximal lifespan of 12%. Further, they are also protected from age-related reduced bone density and susceptibility to fractures, and reduced cardiac function [17662940]. Mouse +30 +12
    ADE4 deletion ade4 mutation extends chronological lifespan, but not replicative lifespan, and is non-additive with 0.5% glucose or amino-acid DR on chronological lifespan extension. ADE4 deletion in atg16 mutants results only in a partial extension of the chronological lifespan by 0.5% glucose DR [20421943]. Yeast
    AFG3 deletion Deletion of the mitochondrial AAA protease AFG3 increases replicative lifespan by 20% in the alpha and a strains [18340043], but decreases chronological lifespan by 37 - 51% in diploid cells [21447998]. AFG3 deletion changes mean, median and maximum lifespan by 15 to 26% 17 to 30% and -25 to +58%, respectively. AFG3 deletion leads to reduced cytoplasmic mRNA translation and its lifespan extension is independent of Sir2 and Hac1, but requires Gcn4. AFG3 deletion further extends the lifespan of cell deficient in both SIR2 and FOB1, but fails to extend the lifespan of dietary restricted cells or cells lacking GCN4. Gcn4 protein levels are increased in afg3 mutants. The deletion of AFG3 fails to extend the replicative lifespan in the W303AR strain. AFG3 deletion does deletion extend the replicative lifespan at 15°C. Yeast -51 to +20
    age-1 mutation Recessive knockout mutants of age-1 have a 40-65% increase in mean lifespan and a 65-110% increase in maximum lifespan [8608934; 8700226]. age-1(mg44) zygotic null mutants have a mean (99%) and maximum (117%) lifespan extension [18828672]. Even in axenic culture lifespan of age-1 is extended up to 100%. age-1 mutation significantly extends lifespan under AL, but only slightly under sDR [16720740]. age-1 mutants are dauer constitutive [8056303] and display lower brood size as well as increased embryonic lethality [9504918]. Additionally, age-1 mutants have elevated levels of superoxidase dismutase and catalase activities [8389142]. Worm +99 +117
    age-1 RNAi RNAi against age-1 extends lifespan by 30% [8700226; 8608934]. age-1 RNAi increases mean and maximum lifespan by 36-46% and 48-50% [12447374]. RNAi against age-1 increases mean lifespan by 83% [18828672]. age-1(mg44) zygotic null mutants have a mean (99%) and maximum (117%) lifespan extension [18828672]. Worm +36 to +99 +48 to +117
    agmo-1 RNAi RNA interference of agmo-1 decreases median lifespan by 30% in wild type animals and 60% in daf-2 mutants [18006689]. Worm -30
    AGP1 deletion Deletion of AGP1 extends chronological lifespan [16418483]. Yeast
    AIM4 deletion AIM4 (alias SOY1) deletion increases chronological and replication lifespan, which is non-additive with DR. On AL mean and maximum replicative lifespan are extended by 63 and 69%, respectively. DR appears to decrease aim4-induced replication lifespan extension, indicating a negative interaction. aim4 mutation does not change DR-induced chronological lifespan extension [21584246]. Yeast +63 +69
    ain-1 RNAi RNA interference of ain-1 decreases median lifespan by 10% in wild type animals, 20% in a daf-2 background and 44% in daf-2/daf-16 double mutants [18006689]. Worm -10
    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
    AKR1 deletion Deletion of AKR1 decreases replicative lifespan by 40% in the alpha strain [18340043]. Replicative lifespan decreased by 50% in the alpha strain [19030232]. Yeast -40 to -50
