    sir-2.1 overexpression 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]. Overrexpression of sir-2.1 synergizes with TGF-beta mutation (daf-4 and daf-1) for dauer formation [11242085]. Worm +50
    Overexpression of constitutive nuclear SKN-1 skn-1 transgenes that overexpress a constitutive nuclear form of SKN-1 in the intestine extend the mean lifespan by 5-21%, independently of DAF-16 [18358814]. Worm +5 to +21
    phi-44 RNAi phi-44 RNAi leads to 46% mean and 50% maximum lifespan extension. Lifespan extension by phi-44 is not suppressed by daf-16. phi-44 RNAi animals have lower ATP content and oxygene consumption [12447374]. Worm +46 +50
    lars-2 mutation A mutation that impairs mitochondrial function was associated with a longer lifespan. Mutation of lrs-2/lars-2(mg312) extends lifespan and is associated with impaired mitochondrial function. The recessive allele mg312 of lars-2 extends lifespan by 200% at 20 degree Celsius and 30% at 25 degree Celsius. Lifespan extension by mg312 was not dependent on daf-16(mgDf47). Homozygous lars-2(mg312) worms had multiple pleotropies like lower rates of growth, pumping and defecation as well as remain the size of early L4 worms and are sterile, with an arrested gonad that exhibited no germ-cell differentiation lars-2 is ubiquitously express, with prominent expression in body-wall muscle and neurons, with a mitochondrial subcellular localisation. Mitochondria of lars-2 are noticeably disorganized, swollen and sometimes fused. lars-2 animals have lower ATP content and oxygen consumption [12447374]. Worm +30 to +200
    age-1 RNAi RNAi against age-1 extends lifespan by 30% [8700226; 8608934]. age-1 RNAi increases mean and maximum lifespan by 36-46% and 48-50% [12447374]. RNAi against age-1 increases mean lifespan by 83% [18828672]. age-1(mg44) zygotic null mutants have a mean (99%) and maximum (117%) lifespan extension [18828672]. Worm +36 to +99 +48 to +117
    sptf-3 Overexpression Overexpression of sptf-3 extends lifespan [18059442]. Worm
    aak-2 overexpression Transgenic animals with a higher aak-2 gene dose live on average 13% longer with a maximum lifespan extension on up to 25% [15574588]. Worm +13 +25
