wwp-1 mutation | Loss of wwp-1 function by mutation reduces lifespan at 25 degree Celsius, but not 20 degree Celsius. Lifespan of wwp-1 mutants across entire food concentration range by bacterial dilution in liquid culture or on solid plates does not noticeable change. Reduced levels of wwp-1 completely suppress the extended longevity of eat-2 mutants [19553937].

skn-1 mutation | skn-1 mutation does not alter lifespan under AL, but cancels out the lifespan extension effect of lDR or food variation at all. Response to lDR in skn-1 mutant is restored by ectopic expression of skn-1 in ASI neurons and gut. Ectopic expression of skn-1b in ASI neurons rescued lDR longevity defects of skn-1. lDR worms exhibit elevated respiration, which is absent in skn-1 mutants. skn-1 is necessary for increased respiration and the increase in respiration is necessary for lDR longevity effect, because two different inhibitors of mitochondrial electron transport chain complex III, myxothiazol and antimycin, suppress lDR longevity without shortening lifespan under AL. IF significantly extends lifespan of skn-1 mutants [19079239]. sDR extends lifespan of a skn-1 loss-of-function mutant (which displays a premature stop codon in all three isoforms) and wild-type to a similar extent [19239417]. skn-1(zu67) mutation decreases mean, median, and maximum lifespan by 11-23, 13-28 and 12-23%, respectively, and totally cancels out lifespan extension by ragc-1 RNAi [22560223]. | Worm | -11 to -23 | -13 to -28 | -12 to -23 |
glp-1 mutation | glp-1(qu158) mutations result in defects in germ-line proliferation and extension of lifespan by about 30%, which requires daf-16 [11799246]. glp-1(bn18) mutation increases mean, median, 75th %ile and maximum lifespan by 27-37, 26-33, 24-29 and 35%, respectively [22560223]. glp-1(e2141) mutation increases mean (32%) and maximum (53%) lifespan [18828672]. Two alleles of glp-1 that cause overproliferation of gemrline cells, glp-1(oz112gf) and glp-1(q485), result in a shortened lifespan [11799246]. In glp-1 mutants, Z2 and Z3 generate only a few germ cells, which enter meiosis and differentiate as sperm [3677168]. | Worm | +27 to +37 | +26 to +33 | +35 |
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 | — | — | — |
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].

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].

aak-2 mutation | aak-2(ok524) knockout mutants have a 12% and 18% shorter mean and maximum lifespan, respectively as well as faster age-dependent accumulation of a lipofuscin-like fluorescent pigment in the intestine [15574588]. aak-2 mutation suppresses lifespan extension and delay of the decline in locomotor activity resulting from sDR [17900900]. aak-2 mutation cancels out the lifespan extension effect of sDR and PD, regardless of the concentration of bacteria or peptones. bDR significantly extends lifespan of aak-2 mutants, but to lesser extent than that of wild-type. eat-2 mutation extends the lifespan of aak-2 mutants to the same extent than that of wild-type. Resveratrol does not increase lifespan of aak-2 mutants [19239417]. daf-2(m577);aak-2(ok524) double mutant has a lifespan that is indistinguishable from those of aak-2(ok524) single mutant [15574588]. | Worm | -12 | — | -18 |
