    ATG18 deletion The replicative lifespan of ATG18 deletion mutant is not shorter than that of wild-type under DR [18690010]. Yeast
    Terc deletion Telomerase null mice exhibit age-dependent telomere shortening and shortened lifespan with succeeding generations. Median lifespan is reduced by 26% in G6 Terc(-/-) mice compared to wild-type or G1-G3 Terc(-/-) (18 months vs. 24 months). G6 Tec(-/-) display hair greying, hair loss, and ulcerative skin lesions, as well as impaired response to wound healing and hematoitopitic ablation, and an increased incidence of cancer [10089885]. Cells from Terc(-/-) mice (G4 and upward) exhibit chromosomes lacking detectable teloemre repeats, aneuplody, and end-to-end fusions [9335332]. Mouse -26
    tdp-1 mutation tdp-1(ok803) mutation increases mean and maximum lifespan at 20 degree Celsius but not at 25 degree Celsius. tdp-1(ok803) reduce the lifespan of daf-2(e1370) mutants, but does not does not reduces the lifespan of daf-16(mu86) mutants [Vaccaro et al. 2012]. Worm
    TCO89 deletion TCO89 deletion increases chronological lifespan, increases mitochondrial oxygen consumption, but decreases mitochondrial and cellular ROS in early stationary phase [21641548]. Deletion of TCO89 cancels out replicative lifespan extension by moderate DR [18690010]. Yeast
    TAE2 deletion TAE2 deletion decreases replicative lifespan by 30% in the a strain [18340043]. Yeast -30
    SWH1 deletion SWH1 (alias OSH1) deletion mutants have an extended replicative lifespan (p=0.02) and DR does not increase the long lifespan of SWH1 deletion mutants [Xia et al. unpublished]. Yeast
    Rgn knockout Survival among make animals lacking Rgn (alias SMP30) is 50% at 180 days compared to 100% among controls [N. Maruyama, unpublished data]. SMP30-/- mutant mice are indstuguishibale form their SMP30+/+ littermates in terms of development and fertilization capacity [12368201]. However, -/- mice were more susceptible to liver injury after treatment with anti-FAS antibody. SMP30-/- hepatocytes cultures in vitro are more susceptible to apoptosis induced by tumor-necrosis factor (TNF-alpha) plus actinomycin D (ActD) than SMP30+/+ hepatocytes. Mouse
    Sod2 homozygous knockout Sod2(-/-) mice are born smaller, pale and less vigorous, and die with 7-10 days. The major problems are dilated cardiomyopathy, accumulaiton of lipid in various tissues particularly liver and skeletal muscle, and metabolic acidosis [7493016]. In another strain background Sod2(-/-) mice have severe anemia, degeneration of neurons in the basal ganglia and brainstem, and progressive weakness, fatigue, and cricling behavior [8790408]. Treatment of Sod(-/-) mice with superoxide dismuate/catalase mimetics (EUK-8, EUK-134, or EUK-189) partially rescues the short lifespan (mean lifespan 14-28 days) and other phenotypes [9462746]. Mouse
    Sod knockout Sod knockout blunts the lifespan extension by a high sugar-low protein diet, but not a low-calorie diet [22672579]. Fly
    Pou1f1 knockout Snell dwarf mutation (Pit1dw) due to knockout of Pou1f1 results in a dramatic lifespan extension. The mean, median and maximum lifespan is increased by 40-50% for Snell dwarf (Pit1dw/Pit1dw) DW/J females, and 25-50% for dwarf DWC3F1 males and females with a compound heterozygous Pit1dw/Pit1dw-J genotype. Although, Snell dwarf (Pit1dw/Pit1dw) DW/J males exhibit aspects of delayed senescence, their median lifespan is by about 25% shorter, probably due to the affects of housing conditions [11718806]. Mice homozygous for loss-of-function mutations at Pit1 locus have a mean and maximum lifespan extension over 40%. Mutant dwJ/dw animals exhibit delays in age-dependent collagen cross-linking and in six age-senstive indices of immune system status. Pituitary transplantation into dwarf mice does not reverse the lifespan extension effect. Male Snell dwarf mice become obese and exhibit proportionately high leptin levels in old age [11371619].

    SLM4 deletion SLM4 deletion blocks replicative lifespan extension by moderate DR, but does not affect lifespan on AL significantly [22912585]. Yeast +2 -10
    slcf-1 mutation slcf-1 mutation increases average lifespan by 40%. DR (by dilution of bacteria on solid medium or by bacterial deprivation) failes to extend slcf-1 mutant's long lifespan and lifespan is even reduced by lowering bacteria concentration (i.e. higher strength of DR) [21040400]. Worm +40
    SIT4 deletion SIT4 deletion slightly increases chronological lifespan and totally abolishes the lifespan shortening due to ISC1 deletion [21707788]. Yeast
    Sirt6 knockout Sirt6 knockout mice develop signs of premature ageing including a short lifespan [16439206]. Mice without Sirt6 have a higher risk of gastrointestinal cancers. Loss of Sirt6 increases the number, size and aggressiveness of tumors. Sirt6 loss leads to tumor formation even without activation of oncogenes. Transformed SIRT6-deficient cells exhibit increased glycolysis and tumor growth [23217706]. Mouse
    Sirt1 knockout Sirt1 knock-out mouse embryonic fibroblasts (MEFs) have a significant greater replicative capacity in culture. p19ARF levels are significantly reduced in Sirt1 knock-out MEFs [16054100]. Sirt1-null mice do not exhibit lifespan extension upon Dietary Restriction [18335035]. Mouse
    sir-2.1 deletion sir-2.1 deletion slightly reduces lifespan of wild-type [16860373]. sir-2.1 suppresses longevity of unc-13 and eat-2, but not daf-2 or unc-64 mutants [16860373]. sir-2.1 is therefore partially required for lifespan extension from mutation of eat-2 [16860373], but is completely independent for lifespan extension from DR using a reduced feeding protocol [Kaeberlein et al. in press]. sDR increases lifespan of wild-type and sir-2.1 mutants to the same extent [19239417]. Worm
    SFA1 YHB1 double mutation sfa1;yhb1 double mutant cancels out the ability of moderate DR to extend replicative lifespan, but not chronological lifespan. Indicating that NO homeostasis during DR-induced replicative lifespan extension is crucial. Deleting YHB1 partially abolished DR-induced replicative lifespan extension, whereas deleting SFA1 alone had no effect. Yhb1 and Sfa1 may play redundant roles [21584246]. Yeast
    sgg transposition Several insertions of P-based vectors in the structural part of sgg are associated with alterations of male and female lifespan [22661237]. Fly
    SCH9 Deletion SCH9 deletion increases chronological lifespan by up to threefold. Stress-resistance transcription factors Msn2/Msn4 and protein kinase Rim15 are required for this life-extension. Deletion of the mitochondrial antioxidant enzyme superoxide dismutase gene SOD2 prevents the increased chronological lifespan caused by SCH9 deletion [11292860]. Mutations that decrease the activity of the Ras/Cyr1/PKA pathway also extend longevity and increase stress resistance by activating transcription factors Msn2/Msn4 and Sod2 [12855292]. SCH9 deletion mutants exhibit more than 3-fold extension of chronological lifespan. By day 9 of medium depletion all the wild-type cells were dead while 50% sch9 mutants survived [17710147]. Deletion of SCH9 also increases resistance to heat shock and oxidative stress [11292860], and increases replicative lifespan by 18% (in DBY746) [12586694]. SCH9 deletion increases the replicative lifespan by 40% in the alpha strain [18340043] and increases mean chronological lifespan by 97 - 246% (97, 133, 154, 226, 246) in diploid cells [21447998]. Mutation or deletion of SCH9 increases resistance to oxidants and extends chronological lifespan [11292860; 16286010]. The extended lifespan of SCH9 deletion mutants is not further extended by low glucose DR and is independent of Sir2 [16293764]. Deletion of RIM15 or GIS1 reverses chronological lifespan extension associated with sch9Delta. Water restriction further increases chronological lifespan of sch9Delta [18225956]. Deletion of SCH9 results in a longer chronological lifespan [21076178]. Yeast +18 to +300
    RTG3 deletion RTG3 deletion mutation causes an increase in mean replicative in lifespan by 55% increase at 2% glucose, suggesting that expression of genes regulated by Rtg1-Rtg3 has a negative effect on longevity in 2% glucose (in YPK9). A null mutant has 123% increased mean lifespan at 0.1% glucose relative to a wild-type strain at 2% glucose, indicating that reduced glucose and an RTG3 mutation have an additive effect on lifespan (in YPK9) [11024000]. RTG3 null mutant cannot grow on acetate medium and requires glutamate or aspartate for growth [9032238]. Yeast +55
    RTG2 deletion RTG2 is required for replicative lifespan extension associated with the retrograde response, a pathway that signals the functional status of mitochondria to the nucleus to regulate the expression of several genes [11024000]. RTG2 is not required for replicative lifespan extension by DR [11024000]. RTG2 null mutants are not petite [8422683], but display various nutrient auxotrphies and alterations of carbohydrate metabolism [7727418]. Yeast
    rsks-1 mutation rsks-1 deletion mutants also live longer. TOR RNA interference further extends lifespan of rsks-1 mutants [17266679]. Worm
    RPS6B deletion RPS6B deletion increases mean replicative lifespan by about 30% [16293764]. Deletion of RPS6B, but not of the RPS6A paralog increases replicative median lifespan robustly by 45% [17174052]. Yeast +30 +45
    RPO41 mutation RPO41 mutants exhibit reduced chronological lifespan accompanied by imbalanced mitochondrial translation, conditional inactivation of respiration, elevated production of reactive oxygen species, and increased oxidative stress [16782871]. Yeast
    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
