    sdhC dominant negative overexpression Mutants expressing a dominant negative form of sdhC in the nervous system have a 22% reduced mean lifespan and signs of oxidative stress induction [17854771]. Fly -22
    Coq7 overexpression Transgenic overexpression of mouse Coq7 reverts the extended lifespan of clk-1 mutants [11511092]. Worm
    Overexpression of constitutive nuclear DAF-16 Overexpression of constitutive nuclear forms of DAF-16 increases lifespan only slightly [11381260]. Worm
    Heterozyogus Trp53 truncation mutation Mice heterozyogous for an allele of p53 that removes the 5' portion of the protein demonstrate decreased cancer, permature aging phenotypes, and shortened lifespan in the mixed inbred C57BL/6–129/Sv background. It has been proposed that the this allele of p53 results in increased activity/overexpression [11780111]. Mouse
    Overexpression of truncated TLC1 Overexpression of a truncated allele of TLC1 abrogates telomere silencing [7545955], shortened telomeres and extends replicative lifespan approximately by 20% [9275199]. Deletion of TLC1 might decrease replicative lifespan [Nugent et al., 1996]. Yeast +20
    Constitutive active S6k overexpression Overexpression of a constitutively active form of S6k (alias dS6K) decreases mean lifespan by 34% at 29°C [15186745]. Fly -34
    Dominant-negative S6k Ubiquitous overexpression of a dominant-negative form of S6k (alias dS6K) increases mean lifespan by 22%. Overexpression of a dominant-negative form of S6k protects mutants from deleterious effects of rich food, as if mimicking the effect of DR [15186745]. Fly +22
    p53 dominant negative overexpression Expression of dominant-negative versions of p53 in adult neurons extends lifespan by 58% in females and by 32% in males and increases resistance to genotoxic stress and resistance to oxidative stress, but not to starvation or heat stress, while not affecting egg production or physical activity. Dominant negative Dmp53 expression cancels out lifespan extension effect of DR, low calorie-food (5% SY). Muscle or fat body specific expression of a dominant negative form of Dmp53 as well as globally lack of Dmp53 decreases lifespan [16303568]. Expression of dominant-negative (DN) form of p53 in adult neurons, but not in muscle or fat body cells, extends median lifespan by 19% and maximum lifespan by 8%. The lifespan of dietary-restricted flies is not further extended by simultaneously expressing DN-DMp53 in the nervous system, indicating that a decrease in Dmp53 activity may be part of the DR lifespan-extending effect. Selective expression of DN-Dmp53 in only the 14 insulin-producing cell (IPCs) in the brain extends lifespan to the same extent as expression in all neurons and this lifespan extension is not additive with DR [17686972].

    Gh antagonist overexpression Overexpression of a growth hormone antagonist (a mutated bovine growth hormone that competes with the endogenous one) has no effect on lifespan [12933651]. Mouse
    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
    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
