    rpr overexpression Flies with ablated wings caused by overexpressing reaper (UAS-rpr) with a wing-specific Gal4 enhancer trap (1096-Gal4) exhibit only a 14% extension in lifespan compared to controls which exhibit a 61% extension upon DR [22768842]. Fly
    Akh overexpression Overexpression of Akh in a ubiquitousness manner enhances fat metabolism (significant increase in triglyceride synthesis and breakdown under AL), spontaneous activity (148% on AL and 154% on DR), and lifespan on AL (33%). However, despite and increase in movement under DR, lifespan is not increased under a restricted diet [22768842]. Fly +33
    pnc-1 overexpression Overexpression of pnc-1 increases adult survival under oxidative stress but does not extend the lifespan [17335870]. Worm
    Trxr-1 overexpression Overexpression of Trxr-1 (alias GSR; glutathione reductase) in transgenic flies results in increased lifespan and oxidative stress resistance, but only under hyperoxia [10506576]. Fly
    Mir20a Overexpression Overexpression of MiR-20a in mouse embryonic fibroblasts induces senescence by lowering Lrf (a transcriptional repressor of the Mdm2 inhibitor p19ARF [15662416; 9529248]) protein levels and in turn increasing p19ARF levels [18596985]. Mouse
    Dnmt gene therapy Injecting a virus that contains extra copies of a Dnmt into elderly mice restored their faulty memories to it oiriganal capacity of young ones. Halving the amount of Dnmt produced by younger mice, deteriotes their memory to that of non-treated older mice [http://www.medicaldaily.com/news/20120702/10573/aging-memory-dna-enzyme-forgetfulness-young-old.htm]. Mouse
    Elevation of histone expression The elevation of histone expression promotes replicative lifespan extension [20832724]. Yeast
    IME1 transient overexpression Transient overexpression of IME1 resets the replicative lifespan of old cells back to that of young cells [21700873]. Yeast
    NDT80 transient overexpression Transient overexpression of NDT80 rejuvenates old cells [21700873]. Yeast
    VhaSFD overexpression Overexpression of VhaSFD (from a doxycycline-inducible promoter) results in a 5-10% increase in mean lifespan [12620118]. Fly +5 to +10
    unc-78 mutation Mutation in unc-78 has no effect on lifespan [9789046]. unc-78 mutants move slowly [7190524]. 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
    CKIepsilon mutation A mutation in CKIepsilon called tau, if homozygous, shortens the circadian period (by 20%), increases metabolic rate (by 20%), and increases lifespan by 14-16% under conditions of constant darkness [12054192]. Male and female wild-type hamsters are heavier than homozygous mutants throughout the entire lifespan, and heterozygous mutants have intermediate weight [12054192]. Hamster +14 to +16
    sug overexpression Overexpression of sug (from a doxycycline-inducible promoter) results in a 5-9% increase in mean lifespan [12620118]. Fly +5 to +9
    SSD1-V overexpression Overexpression of SSD1 (addition of a SSD1-V allele) increases replicative lifespan by 50%, independently of SIR2 and SIR2 further extends the lifespan, although SIR2 is necessary for SSD1-V cells to attain maximal lifespan [15126388]. SSD1-V also dramatically increases chronological lifespan with lifespan twice as long as ssd1-d cells [19570907]. Addition of SSD1-V allele to an ssd1-d strain suppresses the short lifespan of an MPT5 deletion mutant [11805047] and extend wild-type lifespan [Kaeberlein and Guarente, unpublished]. SSD1-V slightly extends the lifespan of swi4 and ccr4 mutant strains and suppresses the temperature sensitive growth phenotype of mpt5, ccr3, swi4, and swi6 single mutants [11805047]. SSD1-V also suppresses the synthetic lethality caused by deletion of MPT5 in combination with a mutation in SWI4, SWI6, or CCR4 [11805047]. SSD1-V suppresses mutations that affect cell wall stability [1545797; 8386319], RNA polymerase III activity [8510644], RNA splicing [10446233], and PKA activity [1848673; 8200529]. Yeast +50 to +100
    SOD2 overexpression Combined overexpression of SOD1 and SOD2 extends chronological lifespan by 30% in EG103 strain [12586694]. Yeast
    Sod2 overexpression Overexpression of Sod2 by 5-115% decreases lifespan by 4-5% without any compensatory changes in metablic rate, level of physical activity, or the levels of other antioxidants (Sod, Cat, and glutathione) [10545213]. Targeted overexpression of Sod2 in motor neurons alone extends lifespan by 30% [11113599]. Induced overexpression of Sod2 in adult animals extends lifespan up to 37% [12072463]. Overexpression of catalase in combination with SOD2 has no added benefit for lifespan [12072463]. Animals overexpressing SOD2 or catalase do not exhibit a decrease in metabolism as measured by oxgen consumption [12072463]. Sod2 overexpression results in a 20% increase in mean and maximum lifespan [18067683]. Fly +20 to +37 +20
    Sod2 overexpression Two-fold overexpression of Sod2 in young (4-6 months) and old (26-28 months) throughout the life results in decreased lipid peroxidation, increased resistance against paraquat-induced oxidative stress, and decreased age-related decline in mitochondrial ATP production, without any change on lifespan or age-related pathology [19633237]. Mouse
    SOD1 overexpression The overexpression of Sods, mitochondrial Sod2 and cytosolic CuZnSod (Sod1), in combination delays the age-dependent reversible inactivation of mitochondrial aconitase, a superoxide-sensitive enzyme, and extends chronological lifespan by 30% [12586694]. Overexpression of SOD1 with CCS1 levuates the level of Cn, Zn-Sod activity and increased chronological lifespan. However overexpression of SOD1 without high cooper or simultonous overexpression of CCS1 shortened both chronological and replicative lifespan [15659212]. Overexpression of SOD1 has no effect on replicative lifespan [10224252]. Yeast
    SNF1 overexpression Overexpression (high-copy 2 micro expression) of SNF1 shortens replicative lifespan to 75% of wild-type and is accompanied by signs of premature ageing, including proegressive sterility, enlargment and fragmentation of the nucleus, redistribution of Sir3 to the nucleus, and more rapid accumulation of extrachromosomal rDNA circles [10921902]. SNF1 overexpression also reduced chronological lifespan [19164565]. Yeast -25
    SIR3 activating mutation The S755A allele of SIR3 (which prevents phosphorylation of Sir3) results in a 40% increase in mean and maximum lifespan [12640455]. Yeast +40 +40
    SIR2 overexpression Integration of a second copy of SIR2 into the wild-type strain leads to an extension of replicative lifespan by around 35% in W303R strain[10521401]. 0.05% glucose restriction further extends replicative lifespan of SIR2 overexpression mutant [15328540]. Overexpression extends replicative lifespan in several strains, but not in PSY316 Yeast +35
    SGS1 overexpression Overexpression of SGS1 extends the maximum lifespan of cells lacking SRS2, but not the mean lifespan [11861900]. Yeast
    SCP1 overexpression Overexpression of SCP1 leads to elevuated ROS levels and reduces chronological lifespan [15024029]. Yeast
    SGS101 chemical induced overexpression Chemical induced overexpression of SAG101 causes precocious senescence in both attached and detached leaves of transgenic plants [11971136].
