    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and this effect was overlapping with moderate DR, because DR can not extend the lifespan of this mutant [Tang et al., unpublished].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
    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
    OSH6 overexpression Elevation of OSH6 levels by an ERG6 promoter extends mean, median and maximum replicative lifespan by 39, 52 and 18% which is non-additive with 0.5% glucose restriction. It also extends the lifespan of NYV1 mutant [Geber et al., unpublished]. The long lifespan of Perg6-OSH6 is not further extended by deletion of TOR1 [22622083]. OSH6 overexpression decreases total cellular sterol content and reduces Lst8 protein levels. The CC domain of Osh6 is dispensable for longevity [Fusheng Tang, personal communication]. Yeast +39 +52 +18
    OSH7 overexpression Overexpression of OSH7 extends mean replicative lifespan. PERG6-OSH7 does not extend the maximum lifespan significantly [Xia et al., unpublished]. Yeast
    PEP4 overexpression Overexpression of vacuolar aspartyl protease (PEP4) extends chronological lifespan by increasing cytosolic polyamine and S-adenosylmethionine (SAM) levels. Deletion of PEP4 results in both apoptotic and necrotic cell death during chronological aging [21593793]. Yeast
    VPH2 overexpression Overexpression of VPH2 increases the levels of assembled V-ATPase at the vacuolar membrane, increases vacuolar acidity and suppresses age-induced mitochondrial dysfunction of aged cells (17 or 18 cell divisions) which requires the V-ATPase activity. VPH2 overexpression significantly increases mean, median and maximum replicative lifespan by 23, 25 and 34%, respectively [23172144]. Yeast +23.1 +25.0 +34.0
    VMA1 overexpression Overexpression of VMA1 increases vacuolar acidity and suppresses age-induced mitochondrial dysfunction of aged cells (17 or 18 cell divisions) which requires the V-ATPase activity. VMA1 overexpression significantly increases mean, median and maximum lifespan by 39 - 45%, 39 - 48% and 50 - 60%, respectively. DR (0.5% glucose restriction) does not further increase the lifespan of VMA1 overexpression strain [23172144]. Yeast +39.3 to +44.8 +39.3 to +48.3 +50.0 to +60.0
