    Ablation of median neurosecretary cells Flies with an ablation of median neurosecretary cells (which eliminates Ilp2 expression) exhibit a significant increase in mean and maximum lifespan over that of control flies and an increase to oxidative stress and starvation. The mutants also exhibit increased storage of lipid and carbohydrate, reduced fecundity, and reduced tolerance of heat and cold [15708981]. The median and maximum lifespan of females is increased by 33.5% and 40%, respectively. In males the median and maximum lifespan is increased by 10.5% and 27%, respectively [15708981]. Fly +10.5 to +33.5 +27 to +40
    Hsp22-promoter driven reporter overexpression Hsp22-promoter driven reporter overexpression reduces mean and maximum lifespan [19420297]. Fly
    Trichostatin A supplementation Histone deacetylase inhibitor Trichostatin A (TSA) extends the lifespan of Drosophila melanogaster by promoting the hsp22 gene transcription, and affecting the chromatin morphology at the locus of hsp22 gene along the polytene chromosome [15346199]. hsp70 and hsp22 RNA levels are higher in long-lived than in short-lived fly lines. The HDAC inhibitor TSA causes a higher expression of hsp22 and hsp70, and strikingly influences the lifespan in both long and short-lived lines, with variable degrees (up to 25%) [15695762]. Fly +25
    Hsc70-3 overexpression Overexpression of Hsc70-3 increases average female lifespan by 27% [18059160]. Fly +27
    hebe overexpression Adult-specific overexpression of hebe increases the lifespan by 5-30% and modulates late-age female fecundity. Female and male mean lifespan is up to 11% and 24% higher [19011900]. Fly +5 to +30
    GstS1 overexpression GstS1 overexpression increases the mean lifespan by 33% [18059160]. Fly +33
    Gr63a overexpression Overexpression of Gr63a has modest negative effect on lifespan [20422037]. Fly
    Gr63a mutation Gr63a loss-of-function in female flies leads to 30% extended mean lifespan, increased fat deposition, and enhanced resistance to some (but not all) environmental stresses. Lifespan of males is not extended [20422037]. Fly +30
    fh overexpression Overexpression of fh in the mitochondria of female transgenic animals increases antioxidant capability, resistance to oxidative stress insults, and longevity [18258192]. Fly
    esc mutation Males heterozygous for the null esc4 or the dominant negative esc9 mutation that are progeny of an out-cross to a O-R wild-type strain have median lifespan that is, respectively, 47% and 60% longer than the O-R control. When derived from an out-cross to a longer-lived C-S wild-type strain, heterozygous esc9 flies have a median lifespan that is 43% longer than the C-S control [20018689]. Fly +47 to +60 +34
    elav mutation elav mutation significantly decreases the lifespan. Median lifespan in males is 66% lower [20589912]. Fly
    Edem1 mutation The mean lifespan of Edem1 mutants of both male and female is increased by more than 30% [19302370]. Fly +30
    E(z) mutation Flies heterozygous for the protein null E(z)63 or the catalytically inactive E(z)731 mutation that are progeny of an out-cross to an Oregon-R (O-R) wild-type strain exhibit a substantially greater median lifespan than the O-R control (71% and 76%, respectively). When derived from an out-cross to a longer-lived Canton-S (C-S) wild-type strain, the median lifespan of E(z)63 heterozygous is 33% longer than the C-S control [20018689]. Fly +33 to +76
    dys RNAi dys RNAi-mediated knockdown in the mesoderm shortens lifespan [18221418]. Fly
    dys knockout Loss of dys function in the heart leads to an age-dependent disruption of the myofibrillar organization within the myocardium as well as to alterations in cardiac performance. Mesodermal dys knockout results in a morderate maximum lifespan reduction (13%), but not when exclusively targeted to the heart. In contrast, half of the transheteozygous DysExel618/Dyskx43 deficiency flies die at 29 days compared to 63 days in controls. This indicates that a moderate dye loss-of-function in all muscles, but not in just the heart, reduces the normal lifespan [18221418]. Fly -13
    DNApol-gamma35 overexpression Overexpression of DNApol-gamma35 (DNA polymerase gamma) in the nervous system results in a decrease in the median lifespan ranging from 39% to 52% [17999718]. Fly -39 to -52
    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
    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
    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
    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
    Bam mutation Bam mutants have an extended lifespan due to germ cell loss. Lifespan of females is on average up to 50% higher and that of males on average s up to 27.8% higher [18434551]. Fly +27.8 to +50
    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
    Atg2 overexpression Atg2 overexpression increases average female lifespan by 28% [18059160]. Fly +28
    alpha-Man-I RNAi alpha-Man-I RNAi knockdown results in a 39% increase in mean lifespan [19302370]. Fly +39
    alpha-Man-I mutation alpha-Man-I mutant fly exhibit enhanced resistance to paraquat and starvation an a 60% increase in mean lifespan for both sexes. After outcrossing, the mutant exhibit, under normal conditions, an increase in mean lifespan of 22% for females and 38% for males. Maximum lifespan is increased by 15% [19302370]. Fly +22 to +60 +15
