    rsks-1 mutation rsks-1 deletion mutants also live longer. TOR RNA interference further extends lifespan of rsks-1 mutants [17266679]. Worm
    rrf-1 mutation Although rrf-1(pk1417) mutants seem to have elevated DAF-16 activity (as sod-3 transcript level is increased) the mean and maximum lifespan or ability to withstand elevated temperature is not different from wild-type [22574120]. Worm
    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
    smk-1 mutation Loss of smk-1 by temperature sensitive allele suppresses the extended lifespan under optimal bDR, but not the response to DR itself [17476212]. Worm
    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
    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
    eat-2 mutation eat-2 mutations result in partial starvation by disrupting the function of the pharynx and an approximately 50% extension of lifespan. eat-2 mutants life significant longer by up to 57% [9789046]. eat-2(ad1116) mutants have an extended mean, 75%ile and maximum lifespan by 30, 35, and 24% [22810224]. sDR further increases the long lifespan of eat-2 mutants [19239417]. eat-2 mutants live longer than wild-type at high food concentration but are short lived at lower concentrations (via bacterial dilution) [19229346]. eat-2(ad1113) mutation increases mean lifespan by 56% and is non-additive with SCNA overexpression [16782295]. Combining eat-2 mutation with bacterial deprivation DR does not result in an additive increase in lifespan [17081160;17096674]. Loss of function of eat-2 extends lifespan by 20-30%. Lifespan extension is proposed to be similar to DR. eat-2;daf-2 double mutant live longer than daf-2 single mutants [9789046]. Therefore, eat-2 mutants can synergize with daf-2 mutants, but not with clk-1 mutants, for lifespan extension. Lifespan extension conferred by eat-2 is not suppressed by daf-16 mutation [9789046]. Worm +30 to +57 +24
    shc-1 knockout Loss of shc-1 function results in accelerated aging and enhanced senstivity ro heat, oxidative stress and heavy metals. Worm
    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
    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
    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
    cup-4 mutation Lifespan of cup-4 mutants increases only moderately by sDR [19783783]. 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
    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
    ced-3 mutation The ced-3(n1286) allele has no effect on lifespan, although the transgenic animals are defective in apoptosis [12136014]. Worm
    che-11 mutation Loss-of-function muation in che-11 increases lifespan up to 40% (in Bristol N2) [10617200]. che-11 mutants are dye filling defective, defective in osmotic avoidance and dauer formation, and have irregular amphid cilia [2428682]. Worm +40
    che-13 mutation Loss-of-function mutation in che-13 increases lifespan up to 40% (in Bristol N2) [10617200]. che-13 Mutants are dye filling defective, have severely shortened axonemes and ectopic assembly of ciliary structures and microtubules in many sensory neurons as well as are defective in osmotic avoidance and dauer defective [2428682]. Worm +40
    che-2 mutation che-2 recessive loss-of-function mutations extend lifespan up to 50% (in Bristol N2) [10617200]. che-2 mutants are chemotactic defective, slightly small, defective for osmotic avoidance, have ciliated neurons with abnormal stunted ultrastructure, and are dauer defective [2428682; 1732156]. Worm +50
    che-2 mutation Loss-of-function in che-3 extends lifespan by 50-100% depending on the allele, but life-extension is suppressed by daf-16 (in Bristol N2) [10617200]. che-3 mutations have defective sensory neurons [2428682; 10508861] and are defective in dye filling [2428682; 7705621] as well as dauer defective [1732156]. Worm +50 to +100
    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
    daf-10 mutation Loss of function mutation in daf-10 increases lifespan by 60% (in Bristol N2) [10617200]. daf-10 mutants are dauer defective, dye filling defective, octopamine deficient and have abnormal chemotaxis and osmotic avoidance. Mutants in daf-10 display abnormal sensory anatomy, especially amophidial neurons and sheath cells, and cephalic neurons. daf-10 mutant males do not mate [2428682]. Worm +60
    daf-12 mutation Mutations in daf-2 and daf-12, but not mutations in daf-12 alone, nearly quadruples lifespan [7789761]. Recessive loss of function mutation in daf-12 shortens lifespan. daf-12 activity is required for lifespan extension after germ line ablation [10360574]. daf-12 mutation suppresses the lifespan extension by mutation in daf-28 [8807293]. daf-12 mutants are dauer defective and heterochronic [7219552]. Some daf-12 alleles exhibit synthetic lethality with mutation of age-1 [8807293] or daf-12 [1732156]. Worm
    hsb-1 mutation hsb-1(cg116) mutation at 20 degree Celsius extends mean, 75%ile, and maximum lifespan by 57-60%, 52-59%, and 37-69%. Worm +57 to +60 +37 to +69
