| VMA2 deletion | VMA2 deletion mutants have a reduced ΔΨ and mitochondrial morphology similar to aged cells. The restoration of the vacuolar acidity in daughter cells requires V-ATPase activity as it is eliminated in VMA2 deletion mutant cells [23172144]. VMA2 deletion mutation decreases the mean replicative lifespan by 80% in the alpha strain [18340043]. Deletion of VMA2 decreases mean, median and maximum replicative lifespan by 84%, 84% and 70%, respectively. DR (0.5% glucose restriction) does not extend the replicative lifespan of VMA2 and shortens it even more [23172144]. | Yeast | -80 to -83.9 | -84.1 | -70.0 |
| 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 | — |
| KSS1 deletion | Deletion of KSS1 results in increased sensitivity to heat shock and oxidative stress and a 25% reduction in median chronological lifespan [17662940]. | Yeast | — | -25 | — |
| AVT1 deletion | Deletion of AVT1 accelerates the development of age-induced mitochondrial dysfunction without effecting the kinetics of vacuolar acidity decline and prevents the suppression of mitochondrial dysfunction by VMA1 and VPH2 overexpression without affecting vacuolar acidity. AVT1 deletion decreases mean, median and maximum lifespan by 21, 22, and 12%, respectively [23172144]. | Yeast | -20.6 | -22.4 | -11.8 |
| Scgdelta deletion | Deletion of Scgdelta has detrimental effects on the flight muscles of adult animals and heart function. Median lifespan is reduced 15-30% [17855453]. | Fly | — | -15 to -30 | — |
| HAC1 deletion | Deletion of HAC1 decreases mean, median and maximum replicative lifespan by 10, 8 and 5%, respectively [23167605]. | Yeast | +10.3 | +8.3 | +5.3 |
| Ilp2 mutation | Ilp2 null mutants are significant longer-lived with a 8-13% longer median lifespan [20195512]. | Fly | — | +8 to +13 | — |
| 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 | — |
| HSP12 deletion | HSP12 deletion slightly increases mean, medium, and maximum replicative lifespan by 24, 27, and 3% under AL, but totally abolishes the lifespan extending effect of moderate DR [Alan Morgan, personal communication; Herbert et al. in press].
HSP12 deletion has no effect on resistance to variety of stresses (including oxidative stress) [Alan Morgan, personal communication]. | Yeast | +24 | +27 | +3 |
| 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]. | Mouse | +25 to +50 | +25 to +50 | +25 to +50 |
| RPL10 deletion | Heterozygosity for RPL10 deletion increases median replicative lifespan by 24% [17174052]. | Yeast | — | +24 | — |
| Efemp1 knockout | Efemp1 knockout mice exhibited an early onset of aging-associated phenotypes including a 20% shorted median lifespan and 30% shorter maximum lifespan, decreased body mass, lordokyphosis, reduced hair growth, and atrophy [17872905]. | Mouse | — | +20 | +30 |
| IDH2 deletion | Deletion of IDH2 increases the mean replicative lifespan by about 30% [16293764]. IDH2 deletion extends mean replicative lifespan by 20% in the alpha strain and in a strain [19030232; 18340043]. IDH2 deletion extends mean, median and maximum lifespan by 15, 19 and 15% [23167605]. | Yeast | +15.4 to +30 | +19.2 | +15.4 |
| TOR1 Deletion | TOR1 deletion extends mean and maximum replicative lifespan by 21 and 25% [16293764] as well as chronological lifespan [21076178]. This lifespan extension is independent of SIR2 and additive with deletion of FOB1 [16293764]. Deletion of TOR1 fails to increase the replicative lifespan of a sir2 mutant [20947565]. Deletion of TOR1 substantially extends chronological lifespan, increasing median survival almost 3-fold (wild-type 4.5 days, tor1 null 12 days), i.e. by 167%. By 21 days in culture, the vast majority of wild-type cells had died (>99.9%), whereas many tor1 null cells remained viable. Deletion of TOR1 also extends the chronological lifespan of the relatively short-lived BY4742 strain, one of the two haploid genetic backgrounds of the widely used Yeast Knockout Collection available from Open Biosystems. Deletion of TOR1 fails to extend chronological lifespan in Petite strains that are unable to respire [17403371]. TOR1 deletion increases replicative lifespan by 30% in the alpha strain and 20% in a strain [19030232]. TOR1 deletion mutant have and increased mean and maximum replicative lifespan by 21% and 6%, respectively [21931558]. Deletion of TOR1 extends replicative lifespan as well as chronological lifespan [21076178] and glucose restriction fails to further extend the long replicative lifespan of tor1Delta [16293764; 16418483; 18225956]. Water starvation (extreme DR) further extends chronological lifespan of tor1 mutants [18225956]. | Yeast | +21 to +30 | +167 | +6 to +25 |
| TMA19 deletion | Deletion of TMA19 increases median replicative lifespan by 16% (P<0.02) [16806052]. TMA19 deletion increases mean replicative lifespan by 25-30% in the alpha and a strains [19030232]. | Yeast | +25 to +30 | +16 | — |
| Heterozyogous fat-specific Insr knockout (FIRKO) | Deletion of Insr specifically in adipose tissue results in a 15-18% increase in mean, median and maximum lifespan. Fat-specific insulin-receptor knockout (FIRKO) reduces fat mass and protects against age-related obesity and its subsequent metabolic abnormality, without an decrease in food intake. Both male and female FIRKO mice have an increase in mean lifespan of around 134 days (18%), with parallel increases in median and maximum lifespan. FIRKO mice consume the same amount of food on per animal basis as control littermates, but have 15-25% lower body-mass and 50-70% reduced fat mass [12543978]. Disruption of Insr in all tissues reults in neonatal lethality [8612577]. | Mouse | +15 to +18 | +15 to +18 | +15 to +18 |
| Whole-body Sirt1 deletion in the adulthood | Whole-body deletion of Sirt1 in the adulthood results in mice which are seemingly normal in every way. When mice were given low doses of resveratrol after Sirt1 was disabled, there were no discernible improvement in mitochondrial function or any paramenter, while mice with normal Sirt1 function given reservatrol showed dramatic increases in energy, mitochondrial biogenesis and function, AMPK activation and increased NAD+ levels in skeletal muscle. When mice lacking Sirt1 were given low doses of reserveratrol, AMPK was unaffected. When doses were significantly increased in these mice, AMPK was activated in a SIRT1-indepent manner, but still no benefit to mitochondrial function resulted [22560220]. | Mouse | — | — | — |

| HNRNPD deletion | HNRNPD deletion leads to accelerated aging as evidenced by strinking telomere erosion, markedly increased DNA damage repsosne at telomere ends, pronounced cellular senescence and rapid premature aging that increases with successive generations [Pont et al., 2012]. | Mouse | — | — | — |
| CKA2 deletion | CKA2 deletion approximately doubles mean chronological lifespan under starvation/extreme DR in BY4741 also increases as well as as heat-shock resistance in SDC medium in the W303-1A and DBY746 genetic backgrounds [20657825]. | Yeast | — | — | — |
