| NPT1 deletion | NPT1 deletion decreases replicative lifespan by 50% [17482543] as well as chronological lifespan [17110466]. Deletion of NPT1 shortens the lifespan in W303R. Replicative lifespan extension of cdc25-10 mutation (assumed to act as a genetic DR-mimetic) is cancelled out by NPT1 deletion [11000115].
NPT1 mutation results in loss of telomere and rDNA silencing [10841563], an effect that is likely caused by a loss of SIR2 activty due to decreased NAD levels. Mutation of NPT1 is synthetical lethal with mutation of QPT1 [11000115]. | Yeast | -50 | — | — |
| Homozygous Gh1 anti-sense transgene | Animals carrying two copies of a Gh1 anti-sense transgene (tg/tg) have a slighlty shorter lifespan (by 5-10%) compared to -/- animals. tg/tg animals are dwarfs and exhibit reduced levels of serum IGF1 [12057928]. | Rat | -5 to -10 | — | — |

| NMT1 mutation | nmt1-451D allele shortens mean and maximum replicative lifespan by 47 and 44% at 24 degree Celsius (permessive temperature). Mutants have decreased resistance to acute and gradual nutrient deprivation, even at the permissive temperature [10921902]. A NMT null mutant is lethal. | Yeast | -47 | — | -44 |

| bar-1 mutation | BAR-1 may play a role in regulating daf-16 during dauer formation, particularly in conditions of oxidative stress as it directly interaction with DAF-16 and loss of bar-1 reduces activity of DAF-16 in dauer formation and lifespan. Deletion of bar-1 reduces mean (44%) and maximal (18%) lifespan, which is to a similar degree as seen to daf-16 mutants [15905404]. | Worm | -44 | — | -18 |

| RAD51 deletion | Rad51 mutations result in a 40% reduced mean replicative lifespan in strain PSY316 [10207108]. RAD51 is required for gene conversion, but not for repair of an HO-induced double-stranded break [8692957]. RAD51 deletion decreases formation of extrachromosomal rDNA circles [10207108]. | — | -40 | — | — |
| RIF deletion | Deletion of RIF1 decrease replicative lifespan by 40% [9275199]. RIF1 deletion increases telomere silencing and length [8319907; 1577274], and therefore likely recruits SIR2 from rDNA to the telomeres which result in lifespan shortening. The sir4-42 allele suppresses the short lifespan of a RIF1 mutant [9275199]. | — | -40 | — | — |
| Hsp22 transposition | Animals that do not express Hsp22 (due to a transposition into its transcriptional starting site) have a 40% decrease in lifespan, exhibit a 30% decrease in locomotor activity and are sensitive to mild stress [20036725]. | Fly | -40 | — | — |
| SOD1 deletion | Deletion of SOD1 decreases replicative lifespan by 40% [17460215]. Cells with a deletion of SOD1 exhibit a profound defect in entry into and survival during stationary phase (i.e. chronological lifespan) in the W303-B strain [8647826; 10222047], which is suppressed by expression of human Bcl-2 [9199172]. Deletion of SOD1 shortens replicative lifespan by approximately 40%. The magnitude of the decrease in lifespan does not appear to dependent on oxygen concentration in the atmosphere [12020810]. Deletion of SOD1 shortens replicative lifespan [10547026] Deletion of SOD1 shortens replicative as well as chronological lifespan [10222047].
Hypersensitivity to oxygene and significantly decreased replicative lifespan of SOD1 deletion can be ameliorated by exogenous ascorbate. If acorbate's negative effects of auto-oxidation are prevented by exchange of medium, ascorbate prolongs mean and maximum replicative lifespan in the atmosphere of air and pure oxygene [15621721].
SOD1 deletion causes sensitivity to hyperoxia as well as methionine and lysine auxotrohies [9199172]. | Yeast | -40 | — | — |

| HAP5 deletion | Deletion of HAP5 shortens replicative lifespan by approximately 40%. This is not a premature aging phenotype as "old" HAP5 cells do not become premature sterile or exhibit other biomarkers of yeast aging [9271578].
