daf-1 mutation | daf-1(mk40) mutation increases mean lifespan by 18-46% and maximum lifespan by 29% [17900898]. The daf-1(m40) allele has no effect on lifespan and fails to prevent lifespan extension by sir-2.1 overexpression, but it results in a temperautre-sensitive, dauer-constitutive phenotype in larvae [11242085]. | Worm | +18 to +46 | — | +29 |
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-11 mutation | Lifespan of daf-11(m84) mutant is not significant different from wild type [8247153]. | Worm | — | — | — |
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 | — | — | — |
daf-14 mutation | daf-14(m77) mutation increases mean lifespan by 21-44% and maximum lifespan by 29% [17900898]. | Worm | +21 to +44 | — | +29 |
daf-15 mutation | Mutations in daf-15 (raptor) extends adult lifespan by 15-30% in a daf-16 dependent manner. daf-15 mutation are dauer defective [15253933]. | Worm | +15 to +30 | — | — |
daf-16 mutation | daf-16(m26) mutation slightly, insignificantly decreases lifespan, but completely suppresses lifespan extension of daf-2(e1370) adults [8247153]. daf-16 is required for lifespan extension by mutation of daf-2 or age-1 [8247153]. Mutations in daf-16 suppressed life-extension caused by mutations in daf-2 [8247153]. Loss of function alleles of daf-16 shorten lifespan, but some alleles have lifespan equal to wild-type [8247153]. daf-16 mutation significantly reduces lifespan under AL (-20%), but does not prevent lifespan extension by sDR. In another experiment daf-16 mutation totally suppresses lifespan extension by sDR [16720740]. sDR does not stimulate DAF-16 translocation to the nucleus, but daf-16 mutation cancelled out the ability of sDR to extend lifespan and to delay the decline in locomotor activity [17900900]. DR by bacterial dilution extends lifespan of daf-16 mutants [17538612]. daf-16 mutation decreases lifespan under AL, but fails to prevent bDR to further extend lifespan [18331616]. IF-induced lifespan-extension by either 24h/48h/72h per 4 days is significantly diminished in null mutants of daf-16. All these regimens extend lifespan of daf-16 to a lesser extent than wild-type. daf-16 partially mediates IF-induced longevity [19079239]. Glucose or glycerol does not shorten lifespan of daf-16 mutants [19883616]. daf-16 mutation cancels out the lifespan extension effect of sDR and PD, regardless of the concentration of bacteria or peptones. bDR significantly extends lifespan of daf-16 mutants, but to a lesser extent than that of wild-type. eat-2 mutation extends the lifespan of daf-16 mutants to the same extent than that of wild-type. Resveratrol extends lifespan of daf-16 mutants [19239417]. daf-16 RNAi completely blocks lifespan extension by daf-2 mutation, but only partially by bDR. daf-16 RNAi attenuates protection against oxidative stress by bDR. daf-16 expression is induced by bDR [19924292]. Knockdown of daf-16 decreases mean and maximum lifespan by 50% and 54%, respectively [22509016]. DAF-16 reduces expression of rsks-1 and daf-15 [15253933; 22560223]. daf-16(mu86) mutation decreases mean (44%) and maximum (18%) lifespan [15905404]. daf-16(mgDf47) decreases mean (18-37%) and maximum (29%) lifespan [18828672]. daf-16 mutants are dauer defective [7219552] and completely suppress all the phenotypes of daf-2 and age-1 mutations, including lifespan extension, dauer arrest, reduced fertility, and viability defects [8247153; 7789761; 9504918; 7789761]. Mutations in daf-16 also suppress lifespan extension of animals that have a germ line ablation [10360574]. Sex-specific lifespan potential requires daf-16 [10747056].
daf-16 mutation suppresses enhanced UV resistance as well as increase longevity of daf-2, daf-23, spe-26, and clk-1 mutants. Mutation in daf-16 does not alter the reduced fertility in spe-26. daf-16 mutants are more fertile than wild-type [8807294]. | Worm | -18 to -37 | — | -29 |
daf-17 mutation | Mutation of daf-17 does not affect lifespan significantly [8247153]. | Worm | — | — | — |
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 | — | — | — |
daf-19 mutation | Loss-of-function mutations in daf-19 increase lifespan up to 50% [10617200]. daf-19 mutants are dauer constitutive, dye-filling defective, and lack sensory cilia [7219552; 9475731]. | Worm | +50 | — | — |
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].

daf-3 mutation | daf-3(mgDf90) mutation decreases mean lifespan by 0-16% and maximum lifespan by up to 9-21%. daf-3(mgDf90) decreases mean lifespan even by 19% [17900898]. Mutation of daf-3 results in a wild-type lifespan, but greatly extends the lifespan of the long-lived daf-9 mutant [11782415]. daf-3 mutations are dauer defective. | Worm | 0 to -19 | — | -9 to -21 |
daf-4 mutation | daf-4(e1374) mutation increases mean and maximum lifespan by 40-120% and 76-83%. daf-4(m63) allele has no effect on lifespan and fails to prevent lifespan extension by sir-2.1 [11242085]. mutation of daf-4 results in a temperature-sensitive, dauer-constitutive phenotype in larvae. sir-2.1 overexpression in the daf-4(m63) background results in an increase in the severity of the dauer-constitutive phenotype [11242085]. | Worm | +40 to +120 | — | +76 to +83 |
daf-5 mutation | daf-5(e1386) mutation reduces mean lifespan by 19% and maximum lifespan by 21% [17900898]. | Worm | -19 | — | -21 |
daf-6 mutation | Loss-of-function mutations in daf-6 extend lifespan by up to 50% [10617200]. daf-6 mutants are dauer defective, chemotaxis defective, osmotic aviodance (osm), male mate poorly, and, dye filling defective [2428682]. Mutants of daf-6 have defective sheath cells causing the amphid and phasmids pores to be closed. | Worm | +50 | — | — |
daf-7 mutation | daf-7 mutation does not significantly change lifespan [8247153]. Mutations in daf-7 cause up to 50% mean and maximum life-extension. This effect is dependent upon daf-3 and on daf-16 but independent of daf-2. daf-7(e1372) increases mean and maximum lifespan by 13-39% and 55%, respectively. daf-7(m62) increases mean and maximum lifespan by 20-29% and 29% [17900898]. | Worm | +13 to +39 | — | +29 to +55 |
daf-8 mutation | daf-8 mutation in adults increases mean lifespan by 9-31% but it did not increase maximum lifespan [17900898]. | Worm | +9 to +31 | — | — |
daf-9 mutation | Mutations in daf-9 increase lifespan up to 52% [11740945]. Mutation of daf-9 extends mean and maximum lifespan at 15 degree Celsius by 15-75% and 28-96%, respectively [11782415]. Lifespan extension conferred by mutation of daf-9 is suppressed by mutation of daf-12, but not by mutation of daf-16. daf-3 mutation results in a wild-type lfiespan, but greatly extends the long-lived daf-9 mutant lifespan. daf-9 mutants are dauer-constitutive [3350212], exhibit gonadal cell migration defect [11782415], and a post-dauer molting defect. | Worm | +15 to +75 | — | +28 to +96 |
daz-1 mutation | Mutation of daz-1 has no effect on lifespan [11799246]. daz-1 mutants are sterile and have a gonad that contains small nuclei and no oocytes [10662646]. Although sperm production is normal, oocytes precursors arrest at meiotic prophase and undergo apoptosis | Worm | — | — | — |
eat-1 mutation | Loss-of-function mutations in eat-1 extend lifespan byy 10-30%. Lifespan extension is proposed to be similar to DR [9789046]. eat-1 mutants have defects in pharyngeal feeding behavior [8462849]. | Worm | +10 to +30 | — | — |
eat-10 mutation | The eat-10(ad606) allele exhibits no significant extension of lifespan [9789046], but displays defects in pharyngeal feeding behaviour [8462849]. | Worm | — | — | — |
eat-13 mutation | The eat-13(ad522) allele extends lifespan by 30%. Extension of lifespan is proposed to be similar to DR [9789046]. eat-1 mutants have defects in pharyngeal feeding behavior [8462849]. | Worm | +30 | — | — |
eat-18 mutation | Mutations in eat-18 extend lifespan by 15-60%. Lifespan extension is proposed to be similar to DR [9789046]. eat-1 mutants have defects in pharyngeal feeding behavior [8462849]. | Worm | +15 to +60 | — | — |
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].
