| ubc-18 | UBiquitin Conjugating enzyme 18 | ubc-18 overexpression is unable to extend lifespan (possibly, UBC-18 is not limiting for WWP-1 function in lifespan). Loss of ubc-18 function by mutation or RNAi reduces lifespan at 25 degree Celsius, but only slightly at 20 degree Celsius. RNAi depletion of ubc-18 completely suppresses increased longevity of eat-2 mutants. RNAi depletion of ubc-18 has no effect on long lifespan of isp-1 or daf-2 mutants. Combined knockdown of wwp-1 and ubc-18 by RNAi does not shorten lifespan any further than RNAi of either single gene. Knockdown of ubc-18 suppresses extended lifespan of wwp-1 overexpression [19553937]. | Nematode |
| trx-1 | ThioRedoXin 1 | Thioredoxins regulate many cellular redox processes. trx-1 is mainly associated with neurons and is expressed in ASJ ciliated sensory neurons and to some extent also on the posterior-most internal cells. trx-1 reduces protein disulfides in the presence of a heterologous thioredoxin reductase. trx-1 null mutant display reduced mean and maximum lifespan [16387300]. Mutants with a deletion in the trx-1 gene display a decrease in lifespan and are sensitive to oxidative stress [16324156]. trx-1 overexpression extends lifespan in wild-type but not in eat-2 mutants. 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. Ectopic expression of trx-1 in ASJ neurons (but not in the intestine) in trx-1 mutants rescues the lifespan-extension conferred by eat-2 mutation. trx-1 overexpression extends lifespan of wild-type but not in eat-2 mutants. trx-1 deletion almost completely suppresses lifespan extension induced by dietary deprivation (DD). DD upregulates trx-1 expression in ASJ neurons. DR activates trx-1 in ASJ neurons which in turn triggers a trx-1-dependent non-cell autonomous mechanism to extend adult lifespan [21334311].

| sod-1 | SOD (superoxide dismutase) | sod-1 overexpression increases mean, median, and maximum lifespan by 32, 25, and 35% [22737090]. | Nematode |
| snap-1 | SNAP (Soluble NSF Attachment Protein) 1 | snap-1 RNAi in the adulthood reduces mean and maximum lifespan by 34 and 50%, respectively [23144747]. | Nematode |
| sir-2.1 | Yeast SIR related 1 | sir-2.1 deletion slightly reduces lifespan of wild-type [16860373]. sir-2.1 overexpression extends lifespan by about 50% and this lifespan extension depends on DAF-16 activity as it is suppressed by mutation in daf-16 and it does not synergize with daf-2 [11242085]. sir-2.1 suppresses longevity of unc-13 and eat-2, but not daf-2 or unc-64 mutants. 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].
Overrexpression of sir-2.1 synergizes with TGF-beta mutation (daf-4 and daf-1) for dauer formation [11242085]. | Nematode |

A nonfunctional wrn-1 DNA helicase decreases the lifespan. The expression of miR-124 in whole wrn-1 mutant worms is significantly reduced. Supplementation with vitamin C normalizes the median lifespan of wnr-1 and mir-124 mutants [23075628]. | Nematode |

Loss of W09C5.8 activity via RNAi can also result in a shortened lifespan, reduced fertility and defects in mitochondrial respiratory chain function [19074434].

| wwp-1 | WW domain Protein (E3 ubiquitin ligase) 1 | RNA interference of wwp-1 decreases median lifespan by 9% in wild-type animals and 24% in daf-2 mutants [18006689]. Loss of wwp-1 function by RNAi or mutation reduces lifespan at 25 degree Celsius, but not 20 degree Celsius. wwp-1 overexpression extends lifespan by up to 20%. Reduced levels of wwp-1 completely suppress the extended longevity of eat-2 mutants. Lifespan of wwp-1 mutants across entire food concentration range by bacterial dilution in liquid culture or on solid plates does not noticeable change. There is no difference in wwp-1 mRNA levels under AL and DR. RNAi reduction of pha-4, but not of daf-16 suppresses increased longevity by wwp-1 overexpression. Mutations in iron sulphur component of complex III, isp-1, increases longevity by reducing mitochondrial function. wwp-1 RNAi does not suppress the extended lifespan of isp-1 mutants and has only minor suppressive effects on lifespan of another mitochondrial mutant, clk-1, and in cyc-1 RNAi treated worms. RNAi depletion of wwp-1 has no effect on long lifespan of daf-2 mutants [19553937]. | Nematode |
