    Ilp2 mutation Ilp2 null mutants are significant longer-lived with a 8-13% longer median lifespan [20195512]. Fly +8 to +13
    foxo mutation foxo null mutants are highly and significantly shorter-lived than wild-type on all food dilutions apart from 0.1 SY and under starvation. foxo null mutants are not more sensitive to starvation than wild-type [18241326]. Fly
    mdt-15 mutation mdt-15(tm2182) mutation does not affect lifespan on ad libitum, but further increases the lifespan when combined with DR (starting at the 4th day of adulthood) even more as wild-type [22132200]. Worm
    nlp-7 mutation Lifespan of nlp-7 mutants increases only moderately by sDR [19783783]. Worm
    ctbp-1 mutation Genetic inactivation of ctbp-1 results in lifespan extension dependent on daf-16, but independent of sir-2.1. RNAi of lips-7(C09E8.2) suppresses lifespan extension by ctbp-1 inactivation [19164523]. Worm
    HPR1 deletion Deletion of HPR1 decreases replicative lifespan [11756539] Yeast
    CIT2 deletion Deletion of CIT2 has no effect on replicative lifespan [10224252]. Yeast
    clk-3 mutation Mutations in clk-3 slow down development and extend adult lifespan (at 20 degree Celsius in Bristol N2). clk-3 mutation slows growth and rhythms similiar to clk-1a and profounds maternal and zygotic rescue [8638122]. Worm
    COQ3 deletion Deletion of COQ3 decreases chronological lifespan and renders cells respiratory deficient and sensitive to hydrogen peroxide [12586694]. Yeast
    COX1 deletion Deletion of mobile group II intron (intron alpha) from COX1 doubles lifespan and prevents accumulation of senescence-associated DNA concatemer corresponding to this of the mitochondrial genome [10330149]. Deletion encompassing COX1's intron alpha and its upstream exon abolishes the senescence process entirely [2999848].
    COX5 deletion Disruption of the nuclear COX5 gene delays senescence, increase longevity between 7- and 15-fold (in 30 tested isolates) and the onset of senescence is not associated by accumulation of senescence-specific mtDNA molecules. COX5 deletion results in exclusive use of the alternative respiratory pathway and a decrease in production of reactive oxygen species and the prevention of the accumulation of several senescence-specific mitochondrial DNA molecules [10759557].
    CPR7 deletion Deletion of CPR7 has no effect on lifespan replicative lifespan, but increases chronological lifespan [11361336] Yeast
    CTF4 deletion Deletion of CTF4 results in an approximately 75% reduced mean replicative lifespan [12024027]. Yeast
    CYT1 deletion Deletion of CYT1 increases replicative lifespan by 15% in the alpha strain and decreases replicative lifespan by 20% in a strain. Deletion of CYT1 decreases replicative lifespan and cancels out replicative lifespan extension by HAP4 overexpression. Initially, it was shown that deletion of CYT1 also prevents lifespan extension by 0.5% glucose restriction [12124627], but later it was shown that either 0.5 or 0.05 % glucose restriction increases replicative lifespan of cyt1Delta cells [16311627]. Yeast
    daf-18 mutation daf-18 is required for complete dauer formation. daf-18 mutation partially suppresses the lifespan extension of age-1 and daf-2 mutants. daf-18 mutants are defective for dauer formation and form some dauer-like larvae when starved [7789761; 8601482]. Worm
    p53 deletion mutation Mice heterozyogous for an allele of p53 that removes the 5' portion of the protein demonstrate decreased cancer, permature aging phenotypes, and shortened lifespan [11780111]. Mouse
    DNA2 deletion Mutants in DNA2 exhibit an accelerated ageing phenotype including extended cell cycle time, age-related transcriptional silencing defects, and nucleolar reorganization, which are all phenotypes of old wild-type cells. Lifespan of DNA2 mutants is extended by expression of an additional copy of SIR2 or by deletion of FOB1 and therefore the lifespan shortening partially suppressed. Three different alleles of DNA2 (dna2-1, dna2-2, and dna2-20) result in a significant shortened lifespan up to 85%. DNA2 mutation shorten the already short lifespan of SGS1 mutants [12024027]. Yeast
    FOB1 deletion Mutation in FOB1 extends replicative lifespan by 30-50% [10230397]. FOB1 mutation increases replicative lifespan by 25% in the alpha strain and by 10% in a strain [19030232]. FOB1 mutant exhibit an about 20% mean replicative lifespan increase [15722108]. Deletion of FOB1 causes extension in the short life span of the sir2 mutant by around 50% [10521401]. Mutation of the FOB1 gene slows the generation of rDNA circles and thus extends life span by approximately 30% in W303 and 50% in K2307 [10230397]. Even in cells lacking both Sir2 and Fob1, nicotinamide prevents the lifespan extension by DR [16311627]. Yeast
    Homozygous GH1 deletion Mean lifespan in untreated, affected individuals homozyogus for a deletion at the GH1 locus is significantly shorter (P < 0.05) than in affected siblings or the general population. Individuals homozygous for GH1 deletion demonstrate hereditary dwarfism [12915652]. Human
    HDA1 deletion Deletion of HDA1 has no effect on longevity under AL, but acts synergistically with 0.1% glucose restriction to increase replicative lifespan [12213553]. Deletion of HDA1 leads to a slightly increased chronological lifespan [19801973]. Deletion of HDA1 has no effect on the wild-type lifespan in the short-lifespan of YSK771 strain, but suppresses the short-lifespan of SIR3 mutants [10512855]. Null mutation results in increased telomeric silencing and increased histone acetylation [8962081]. Yeast
    YKU70 deletion Deletion fo YKU70 shortens lifespan, but does not accelerate the normal aging process [10521401]. YKU70 null mutants are defective for non-homologous end-joining [8754818] and for telomeric silencing [9635192]. Yeast
    YKU80 deletion Deletion of YKU80 shortens replicative lifespan, but does not accelerate the normal aging process [10521401]. YKU80 null mutant is defective for non-homologous end-joining [8754818] and for telomere silincing [9501103; 9635192] Yeast
    HSC82 deletion Deletion of HSC82 has no effect on replicative lifespan, but shortens chronological lifespan [11361336]. Yeast
    LAC1 deletion Deletion of LAC1 the homolog of LAG1 [9872981] has no effect on replicative lifespan in strain W303R and PSY316 [N. Bishop, G. Liszt, and L. Guarente, unpublished]. LAC1 null mutant has no obvious growth defect [10198056], but is synthetically lethal with LAG1 mutation [9872981]. Yeast
    MSN2 MSN4 double mutation Deletion of MSN2 and MSN4 extends replicative lifespan and is further extended by cyr1::mTn [14741356]. Deletion of MSN2 and MSN4 does not significantly decrease chronological lifespan under AL, but attenuates chronological lifespan extension by water starvation and 0.5% glucose restriction [18225956] as well as cancels out lifespan extension of cyr1::mTn [14741356] and decreases chronological lifespan extension of ras2 deletion mutant [12586694]. Simulatnous deletion of MSN2 and MSN4 has no effect on chronological lifespan, but prevents lifespan extension by RAS2 deletion [12586694]. msn2 msn4 has no effect on replicative lifespan in PSY316, and does not prevent lifespan extension by DR [11000115] or by high osmolarity [12391171].
