    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the short lifespan of an MPT5 deletion mutant [11805047] and extend wild-type lifespan [Kaeberlein and Guarente, unpublished].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
    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
    Elevation of histone expression The elevation of histone expression promotes replicative lifespan extension [20832724]. Yeast
    NNT1 overexpression Overexpression of NNT1 by 5-fold extends mean and maximum replicative lifespan by 18 and 23%, which is approximately of the same magnitude as the lifespan extension obtained from DR.DR in NNT1 overexpression mutant fails to significantly affect the lifespan and only results in extended mean lifespan by 12% and reduced maximum lifespan by 11%. NNT1 overxpression increases rDNA silencing [12736687]. Yeast +18 +23
    ERG2 overexpression Overexpression of ERG2 with the promoter of ERG6 (Perg6-ERG2) extends replicative lifespan and this effect was overlapping with moderate DR, because DR can not extend the lifespan of this mutant [Tang et al., unpublished]. Yeast
    TSA1 activating mutation A gain-of-function allele of peroxiredoxin (thioredoxin peroxidase, Tsa1) causes a dominant oxidative stress-resistance and robust premature aging phenotype with reduced mean lifespan. These effect is not provoked by altered Tsa1 levels, nor can it be stimulated by deletion, haploinssufficiency or overexpression of wild-type allele [20729566]. Yeast
    NPT1 overexpression Increased dosage of NPT1 increases SIR2-dependent silencing, stabilizes the rDNA locus and extends replicative lifespan by up to 60%. 0.5% glucose restriction does not significantly further increase replicative lifespan of NPT1 overexpression [11884393]. NPT1 deletion decreases replicative lifespan by 50% [17482543] as well as chronological lifespan [17110466]. Deletion of NPT1 shortens the lifespan in W303R. Replicative lifespan extension of cdc25-10 mutation (assumed to act as a genetic DR-mimetic) is cancelled out by NPT1 deletion [11000115]. Yeast +60
    MDH1 overexpression Overexpression of MDH1 extends replicative lifespan by 25% and does not synergize with 0.5% glucose restriction [18381895]. Yeast +25
    NDE1 NDE2 overexpression Overexpression of NDE1 and NDE2 increases intracellular NAD/NADH ratio by lowering NADH concentration and increases replicative lifespan by 20-25%. This lifespan extension is non-additive with 0.5% glucose restriction [14724176]. Yeast +20 to +25
    LAT1 overexpression In contrast, overexpressing LAT1 extends replicative lifespan, and this lifespan extension was not further increased by 0.5% glucose restriction. Similar to DR, replicative lifespan extension by LAT1 overexpression largely requires mitochondrial respiration [17200108]. Overexpressing Lat1 extends lifespan (20% mean lifespan increase) and this lifespan extension is not further increased by DR. Similar to DR, lifespan extension by LAT1 overexpression largely requires mitochondrial respiration indicating mitochondrial metabolism plays an important role in DR. Interestingly, LAT1 overexpression does not require the Sir2 family to extend lifespan. Lat1 is also a limiting longevity factor in non-dividing cells in that overexpressing LAT1 extends cell survival during prolonged culture at stationary phase. Yeast +20
    HST2 overexpression HST2 overexpression extends replicative lifespan. 0.5% glucose restriction does not increase lifespan of sir2;fob1;hst2 triple mutants [16051752]. DR increases lifespan of all four sir2;fob1;hstX(X = sirtuin) triple mutants [16741098; 17129213]. Yeast
    HAP4 overexpression Overexpression of HAP4 from the ADH1 promoter extends lifespan of PSY316 strain approximately 40% under growth conditions favoring fermentation (2% glucose). Overexpression of HAP4 increases replicative lifespan, but is non-additive with 0.5% glucose restriction in lifespan extension. Lifespan extension by HAP4 overexpression requires SIR2 [12124627]. HAP4 deletion suppresses replicative lifespan extension to 30% and 33% on 0.1% glucose and on elimination of non-essential amino acids, respectively [20178842]. HAP4 overexpressing cells demonstrate a transcriptional response resembling cells undergoing diauxic shift, consume more oxygen, and exhibit increased Sir2-dependent transcriptional silencing at telomeres and rDNA [12124627]. Yeast +30 to +40
    GUT2 overexpression Overexpression of GUT2 extends replicative lifespan by 25% and does not synergize with 0.5% glucose restriction [18381895]. Yeast +25
    AAT1 overexpression Overexpression of AAT1 extends replicative lifespan by 25% and does not synergize with 0.5% glucose restriction [18381895]. Yeast +25
    RAS2 overexpression Overexpression of RAS2 causes a 43% increase in mean and 18% increase in maximum lifespan as well as postpones the age-related increase in generation time [8034612]. Yeast +43 +18
    CLN3 overexpression Overexpression shortens chronological lifespan together with age-dependent increases in genome instability and apoptosis. While around 80% of wild-type cells are alive almost non CLN3 overexpressers are alive (under condition that avoids adaptive regrowth) [17710147]. Yeast
    FBP1 overexpression Overexpression of FBP1 shortens chronological lifespan [16199065]. Yeast
    CTA1 overexpression CTA1 overexpression partially suppresses the shortened chronological lifespan by ISC1 mutation [21707788]. Yeast
    MAPK1 overexpression Overexpression of human MAPK1 (alias ERK2) confers resistance to heat shock and oxidative stress extends median chronological lifespan by 24% and was statistically non-addative with cyr1-1 mutation [17662940]. Yeast +24
    MXR1 overexpression Overexpression of MXR1 (alias MsrA) slightly increases the replicative lifespan [15141092]. Yeast
    MXR2 overexpression Overexpression of MXR2 (alias MsrB) has no effect on replicative lifespan under normal growth conditions, but under DR conditions extends replicative lifespan by 120% [15141092]. Yeast
    YDC1 overexpression YDC1 overexpression decreases chronological lifespan by 40% [19059240]. Yeast -40
    BMH2 overexpression Overexpressing 14-3-3 protein, Bmh2, significantly extends median chronological lifespan by activating stress response [19805817]. Yeast
    OSH3 overexpression Overexpression of OSH3 with the promoter of VAC8 shortens mean replicative lifespan ad promotes vacuolar fusion [Xia et al. unpublished]. Yeast
