    ins-35 mutation Mutation of ins-35 extends lifespan on NGM agar covered with killed or live bacteria as well as in liquid culture medium. ins-35(TM290) mutation extends mean, 75%ile, and maximum lifespan by 15-17, 14-23, and 23-24%. Lifespan extension by ins-35 mutation is totally abolished by daf-16 or skn-1 RNAi inactivation eat-2 RNAi further enhances the extension of lifespan by mutation in ins-35 [22768380]. Mutation of ins-35 enhances pheromone-induced dauer formation [22768380]. Worm +15 to +17 +23 to +24
    shk-1 mutation Mutation of shk-1 extends lifespan on NGM agar covered with killed or live bacteria as well as in liquid culture medium. shk-1(RB1392) mutation extends mean, 75%ile, and maximum lifespan by 19-22, 19-21, and 20-24%. Lifespan extension by unc-17 mutation is totally abolished by RNAi inactivation of either daf-16 or skn-1. eat-2 RNAi shortens the lifespan of shk-1 mutants [22768380]. Mutation of shk-1 enhances pheromone-induced dauer formation [22768380]. Worm +19 to 22 +20 to 24
    ife-2 mutation Loss-of-function mutation in ife-2 reduces protein synthesis and increases maximum lifespan by about 20%. It does not extend the lifespan of daf-16(RNAi) animals. TOR/let-373 RNA interference further extends lifespan of ife-2 mutants. Reduction of protein synthesis increases ATP availability and stress resistance [17266679]. Worm +20
    SNCA overexpression Transgenic lines overexpressing either human wild-type or mutant (A53T) forms of the SNCA (alpha-synclein) gene under a pan-neuronal promoter live on average about 25% longer, even in weak (m577) and strong (e1370) daf-2 mutant backgrounds, and exhibited decreased pharyngeal pumping and egg-laying. Wild-type SNCA crossed into eat-2(ad1113) does not significantly effect lifespan compared to that of the background strain. Pumping rate in wild-type SCNA and A53T SCNA overexpression mutants were less than control already at day 1 of adulthood. The attenuation of lifespan exptesion by SNCA overexpression by growing on thick bacterial lawns, suggests that DR may explain some fo the effects on lifespan. SCNA overexpression increases average lifespan by 21.3% (wild-type) and 16.3% (A53T) [16782295]. Worm +26 to +34 +19 to +31
    glc-4 mutation Mutation of glc-4 extends lifespan on NGM agar covered with killed or live bacteria as well as in liquid culture medium. glc-4(JD31) increases the mean, 75%ile, and maximum lifespan by 13-23, 11-23, 19-34%. Lifespan extension by glc-4 mutation is totally abolished by RNAi inactivation of either daf-16 or skn-1. eat-2 RNAi further enhances the extension of lifespan by glc-4 mutation [22768380]. Mutation of glc-4 suppresses pheromone-induced dauer formation [22768380]. Worm +13 to +23 +18 to +34
    gar-3 mutation Mutation of gar-3 extends lifespan on NGM agar covered with killed or live bacteria as well as in liquid culture medium. gar-3(VC670) mutation extends mean, 75%ile, and maximum lifespan by 5-18, 4-7 and 15-56%. Lifespan extension by gar-3 mutation is not abolished by RNAi inactivation of daf-16, skn-1, or eat-2 [22768380]. Worm +5 to +18 +15 to +56
    daf-2 mutation daf-2 mutants live more than twice as long as controls. daf-2(sa189) mutation extends mean and maximum lifespan by 133 and 129%, respectively, when shifted to 20 degree Celsius. The daf-2(e1370) mutation extends mean and maximum lifespan by 32 and 119%, respectively, when shifted to 25 degree Celsius and by 110 and 145%, respectively, at 20 degree Celsius. daf-2(sa189) mutation extends mean lifespan by 67% as well as maximum lifespan [8247153]. This lifespan extension requires the activity of daf-16 [8247153]. The lifespan extension of daf-2(e1370) mutants is cancelled out by daf-16(m26) mutation. daf-2 mutants still exhibit a long lifespan after ablation of the gonad and germ cells. [8247153]. daf-2(e1370) increases mean (95-118%) and maximum (165%) lifespan [18828672]. daf-2 mutation extends lifespan of wild-type and eat-2 mutants [9789046]. Long lifespan of daf-2 insulin receptor mutation is further extended by sDR. However, daf-2 mutation is not a null mutation, therefore it is still possible that part of sDR-induced increase in lifespan might depend on insulin receptor pathway [17900900]. DR by bacterial dilution extends lifespan of daf-2 mutants [17538612]. IF does not markedly extend lifespan of daf-2 mutants [19079239]. 2% glucose reduce fractions of animals that become dauers at 22.5 degree Celsius in daf-2 mutants. Glucose almost completely suppresses lifespan extension of daf-2 ligand binding domain and tyrosine kinase mutants back to wild-type levels [19883616]. daf-2 mutation increases average lifespan by 157%. Under AL daf-2 mutation increases lifespan by 30%. bDR increases lifespan by 65%. daf-2 mutation further increases lifespan under bDR by 40%. Resistance to oxidative stress is reduced daf-2 mutation [19924292]. daf-2(m577) mutation increases mean and maximum lifespan by 33 and 29%, respectively, while daf-2(e1370) mutation increases mean and maximum lifespan by 101 and 181%, respectively [16782295]. DR from eat-2(ad465) mutation has an addative effect on lifespan of daf-2(e1370) adults, but not on lifespan of daf-2(e1368) adults [18043747]. Mutation in daf-2 in combination with mutation of daf-12 results in nearly 300% increase in lifespan [7789761]. daf-2 mutants are dauer constitutive [7219552] and exhibit reduced brood size [9504918; 9725835]. daf-2 mutants synergize with germ line ablation for lifespan extension [10360574] and also exhibit synergy with clk-1 mutation for lifespan prolongation [8638122]. All the phenotypes of daf-2 mutants are suppressed by mutation of daf-16 [8247153; 8601482; 7789761; 9725835; 9504918]. Mutation of daf-2 increases expression of sod-3 [10428762]. daf-2(e1370) increases mean lifespan by 146% [23097426]. Worm +32 to +146 +119 to +165
    age-1 mutation Recessive knockout mutants of age-1 have a 40-65% increase in mean lifespan and a 65-110% increase in maximum lifespan [8608934; 8700226]. age-1(mg44) zygotic null mutants have a mean (99%) and maximum (117%) lifespan extension [18828672]. Even in axenic culture lifespan of age-1 is extended up to 100%. age-1 mutation significantly extends lifespan under AL, but only slightly under sDR [16720740]. age-1 mutants are dauer constitutive [8056303] and display lower brood size as well as increased embryonic lethality [9504918]. Additionally, age-1 mutants have elevated levels of superoxidase dismutase and catalase activities [8389142]. Worm +99 +117
    cha-1 mutation Mutation of cha-1 extends lifespan on NGM agar covered with killed or live bacteria as well as in liquid culture medium. cha-1(TY1652) mutation extends mean, 75%ile, and maximum lifespan by 23, 29, and 38%. The cha-1(PR1152) allele extends mean, 75%ile, and maximum lifespan by 22-49, 18-25, and 11-21%. Lifespan extension by cha-1 mutation is not abolished by daf-16 RNAi inactivation. eat-2 RNAi shortens the lifespan of cha-1 mutants [22768380]. Worm +22 to +49 +11 to +21
    isp-1 mutation A missense mutation in isp-1 leads to low oxygen consumption, decreased sensitivity to reactive oxygen species, and increased mean (60%) and maximum (100%) lifespan. An isp-1;daf-2 double mutant has a lifespan that is longer than either single mutant, but the lifespan extension of the double mutant is not addative relative to each single mutant [11709184]. Worm +60 +100
    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
    pdk-1 mutation Loss-of-function alleles in pdk-1 extend lifespan by 60% [10364160]. pdk-1(sa680) mutants are dauer constitutive (suppressed by daf-16) [10364160]. Worm +60
    trx-1 mutation Mutants with a deletion in the trx-1 gene display a decrease in lifespan and are sensitive to oxidative stress [16324156]. trx-1 null mutant display reduced mean and maximum lifespan. trx-1 deletion completely suppresses the lifespan extension caused by eat-2 mutation, but only partially suppresses that by daf-2 or osm-5 mutations [16387300]. Worm
    pept-2 mutation Deletion of pept-1 (alias opt-2 or pep-2) results in retarded development, reduced body size and extended reproductive lifespan. It also further extends (60%) the life-extension caused by daf-2 mutations [15155758]. pept-2 mutants exhibit a decrease in fat content. Worm
    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
    pgl-1 mutation pgl-1(bn101) mutant animals that are sterile have a approximately 35% longer lifespan. In contrast, fertile pgl-1(bn101) animals have a wild-type lifespan [11799246]. PGL-1 is required for fertility and proliferation of germ line cells [9741628]. Worm +35
    asg-2 mutation Knockout mutations in asg-2 result in developmental arrest and increased lifespan [11410594]. Worm

    nlp-7 mutation Lifespan of nlp-7 mutants increases only moderately by sDR [19783783]. Worm
    unc-51 mutation unc-51(e369) mutation reduces mean but extends maximum lifespan. unc-51(e369) mutation reduces lifespan of eat-2(ad1116) mutants to that of wild-type [18219227]. 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
    C26B2.2 knockout C26B2.2 knockout mutations extend lifespan [15253933]. Worm
    cdc-25.3 knockout cdc-25.3 knockout mutants also display increased thermotolerance and a 40% lifespan extension [16741121]. Worm +40
    ced-3 mutation The ced-3(n1286) allele has no effect on lifespan, although the transgenic animals are defective in apoptosis [12136014]. Worm
    cep-1 mutation cep-1 mutants live up to 33% longer. which is dependent upon functional daf-16 [17895432]. Worm +33
