| ucp2 | uncoupling protein 2 | Overexpression of zebrafish's ucp2 in nematode increases mean, median, and maximum lifespan by 42, 40, and 26%, which is non-additive with sDR [22737090]. | — |
| aakg-2 | AMP-Activated protein Kinase Gamma subunit 2 | aakg-2 overexpression extends mean, median, and maximum lifespan by 47, 45, and 35%. Overexpression of aakg-2 toegther with D. rerio ucp2 was non-additive with sDR [22737090]. | Nematode |
| unc-51 | UNCoordinated-51 | unc-51(e369) mutation reduces mean but extends maximum lifespan. unc-51(e369) mutation reduces lifespan of eat-2(ad1116) mutants to that of wild-type [18219227]. | Nematode |
| ckr-1 | CholecystoKinin Receptor homolog 1 | ckr-1 RNAi significantly reduces lifespan of eat-2 but not that of age-1 nor clk-1 mutants [19783783]. | Nematode |
| mdt-15 | MeDiaTor 15 | mdt-15(tm2182) mutation does not affect lifespan on ad libitum, but further increases the lifespan when combined with DR (starting at the 4th day of adulthood) even more as wild-type [22132200]. | Nematode |
| CG5389 | — | RNAi of complex V subunit CG5389 results in increased mean longevity under standard laboratory food conditions (3% yeast) in males. RNAi started from the development results in a mild lifespan increase in both sexes (3-11% in females and 3-8% in males). Post-developmental RNAi and silencing limited to neurons has variable effects with reduction in lifespan of up to 9% [19747824]. Under rich media conditions CG5389 knockdown throughout development and adulthood increases mean lifespan by 26% and abolished the lifespan extension by DR (started in the adulthood) in males. Suppression of CG5389 only during the adulthood either via RNAi by tub-GS or via oligomycin (a specific inhibitor of complex V) feeding prevents an increase in longevity under DR (started in the adulthood) in males [19968629]. | Fruit fly |
| Sirt1 | sirtuin 1 (silent mating type information regulation 2, homolog) 1 (S. cerevisiae) | Whole-body deletion of Sirt1 in the adulthood results in mice which are seemingly normal in every way. When mice were given low doses of resveratrol after Sirt1 was disabled, there were no discernible improvement in mitochondrial function or any parameter, while mice with normal Sirt1 function given reservatrol showed dramatic increases in energy, mitochondrial biogenesis and function, AMPK activation and increased NAD+ levels in skeletal muscle. When mice lacking Sirt1 were given low doses of reserveratrol, AMPK was unaffected. When doses were significantly increased in these mice, AMPK was activated in a SIRT1-indepent manner, but still no benefit to mitochondrial function resulted [22560220]. Sirt1 overexpression mimicks the effect on reservatrol on mitochondrial function, but failed to extend lifespan [22560220].
SIRT1 knock-out mouse embryonic fibroblasts (MEFs) have a significant greater replicative capacity in culture. p19ARF levels are significantly reduced in SIRT1 knock-out MEFs [16054100].
Sirt1-null mice do not exhibit lifespan extension upon Dietary Restriction [18335035].
Sirt1 is required for high-magnitude circadian transcription of several core clock genes. It deacetylates Per2, Arntl and histones of clock-controlled genes [18662546].
SIRT1 directly [21187328] and indirectly [20450879] prevents telomere shortening. | House mouse |
| VPS21 | Vacuolar Protein Sorting 21 | Lack of VPS21 reduces lifespan under starvation conditions to a level similiar to that of wild-type cells incubated in synthetic complete medium and therefore blocked the lifespan-extending effect of DR [20657825]. | Budding yeast |
| VPS8 | Vacuolar Protein Sorting 8 | Lack of VPS8 reduces lifespan under starvation conditions to a level similiar to that of wild-type cells incubated in synthetic complete medium and therefore blocked the lifespan-extending effect of DR [20657825]. | Budding yeast |
| MSN2 | Multicopy suppressor of SNF1 mutation 2 | Deletion of MSN2 and MSN4 extends replicative lifespan and is further extended by cyr1::mTn [14741356]. Deletion of MSN2 and MSN4 does not significantly decrease chronological lifespan under AL, but attenuates chronological lifespan extension by water starvation and 0.5% glucose restriction [18225956] as well as cancels out lifespan extension of cyr1::mTn [14741356] and decreases chronological lifespan extension of ras2 deletion mutant [12586694]. Simultaneous deletion of MSN2 and MSN4 has no effect on chronological lifespan, but prevents lifespan extension by RAS2 deletion [12586694]. msn2 msn4 has no effect on replicative lifespan in PSY316, and does not prevent lifespan extension by DR [11000115] or by high osmolarity [12391171]. | Budding yeast |
| MSN4 | Multicopy suppressor of SNF1 mutation 4 | Deletion of MSN2 and MSN4 extends replicative lifespan and is further extended by cyr1::mTn [14741356]. Deletion of MSN2 and MSN4 does not significantly decrease chronological lifespan under AL, but attenuates chronological lifespan extension by water starvation and 0.5% glucose restriction [18225956] as well as cancels out lifespan extension of cyr1::mTn [14741356] and decreases chronological lifespan extension of ras2 deletion mutant [12586694]. Simultaneous deletion of MSN2 and MSN4 has no effect on chronological lifespan, but prevents lifespan extension by RAS2 deletion [12586694]. msn2 msn4 has no effect on replicative lifespan in PSY316, and does not prevent lifespan extension by DR [11000115] or by high osmolarity [12391171]. | Budding yeast |
| HST1 | Homolog of SIR Two (SIR2) 1 | Deletion of HST1 blocks the residual replicative lifespan extension by hxk2 mutant in a sir2;fob1;hst2 triple mutant background [16051752]. However, DR can increases the replicative lifespan to a similar extent in sir2;fob1;hst1;hst2 quadruple mutant cells as in sir2;fob1 double mutant cells under 0.5, 0.05 and 0.005% glucose conditions and even by hxk2 deletion mutant [16741098; 17129213]. | Budding yeast |
| PCK1 | Phosphoenolpyruvate CarboxyKinase 1 | Loss of Pck1 activity blocks chronological lifespan extension caused by water starvation. Knockout of PCK1 dramatically reduces chronological lifespan in both water (extreme DR) and glucose-containing medium. pck-1-K514Q mutation which abrogates enzymatic activity of Pck1, just like SIR2 deletion, extends chronological lifespan in water. Deletion of SIR2 does not alter the lifespan of PCK1 deletion mutant, pck1-K514R, and pck1-K514Q mutants [19303850]. | Budding yeast |
| GSH1 | glutathione (GSH) 1 | Deletion of GSH1 confers deficiency in glutathione biosynthesis and further increases chronological lifespan under 0.5% glucose restriction, but does not extend chronological lifespan under 2% glucose [18840459]. Therefore, GSH1 has a positive interaction with DR [18840459]. | Budding yeast |
| ERG3 | ERGosterol biosynthesis | Deletion of ERG3 decreases replicative lifespan under AL, cancels out replicative lifespan extension of 0.5% glucose DR and results under DR also into a shorter replicative lifespan than under AL [18690010]. | Budding yeast |
| SUR4 | SUppressor of Rvs161 and rvs167 mutations 4 | Deletion of SUR4 cancels out replicative lifespan extension of 0.5% glucose DR [18690010]. | Budding yeast |
| LCB4 | Long-Chain Base 4 | Deletion of LCB4 increases replicative lifespan and cancels out replicative lifespan extension of 0.5% glucose DR [18690010]. | Budding yeast |
| HSP12 | Heat Shock Protein 12 | HSP12 deletion slightly increases mean, medium, and maximum replicative lifespan by 24, 27, and 3% under AL, but totally abolishes the lifespan extending effect of moderate DR [Alan Morgan, personal communication; Herbert et al. in press].
HSP12 encodes a small heat-shock protein which mRNA levels increases in response to diverse environmental stresses (including heat-, osmotic-, and oxidative stress) [11102521; 10722658] and its protein levels are induced upon both DR and high osmolarity. However, HSP12 deletion has no effect on resistance to variety of stresses (including oxidative stress). Hsp12 is monomeric, has negligible in vitro protein chaperone activity, and is intrinsically unstructured/unfolded in water, but switches to a dynamic 4-helical conformation upon membrane binding. These all indicates that Hsp12 has membrane-stabilising "lipid chaperone" functions and while its low levels exerts some negative effects on lifespan high levels of Hsp12 are required for DR-induced lifespan extension [Alan Morgan, personal communication; Herbert et al. in press]. | Budding yeast |
| NFU1 | NifU-like protein 1 | NFU1 mutation slightly shortens the chronological lifespan under AL and the chronological lifespan of NFU1 mutants is not extended by 0.5% glucose DR [20421943]. | Budding yeast |
| FET3 | FErrous Transport 3 | FET3 mutation slightly shortens chronological lifespan under AL. Its chronological lifespan is not extended by 0.5% glucose or amino-acid DR [20421943]. FET3 is one of several iron related genes that are up-regulated in response to increasing strength of glucose DR [18679056]. | Budding yeast |
| ATG16 | AuTophaGy related 16 | Under AL atg16 mutation shortens chronological, but not replicative lifespan. 0.5% glucose DR extends chronological lifespan of atg16 mutants, but amino-acid DR does not extend the short chronological lifespan of atg16 mutants (similar to several other autophagy mutants). ADE4 deletion in atg16 mutants results only in a partial extension of chronological lifespan by 0.5% glucose DR. The long chronological lifespan of tor1 mutants requires ATG16 [20421943]. | Budding yeast |
| ATG2 | AuTophaGy related 2 | ATG2 deletion prevents chronological lifespan extension induced by amino-acid DR [20421943]. | Budding yeast |
| VPS30 | Vacuolar Protein Sorting 30 | VPS30 deletion prevents chronological lifespan extension induced by amino-acid DR [20421943]. | Budding yeast |
| gpa2 | Guanine nucleotide-binding protein alpha-2 subunit | gpa2 (alias git8) encodes the alpha subunit of a heterotrimeric G protein, which acts downstream of Git3. Git8 activity accelerates aging and inhibits the lifespan-extending effect of DR. Constitutive active mutation of gpa2 decreases chronological lifespan under AL (2% glucose) and almost completely cancels out the lifespan extending effect of DR (0.2% glucose) [19266076]. | Fission yeast |
| sty1 | — | Deleting sty1 cancels out chronological lifespan extension and enhanced heat stress resistance by DR. Sty1 (phosphorylated) and Sty1-dependent gene transcription (atf1, gpx1, cta1, fbp1) is activated during DR in the stationary phase, but are barely activated in glucose rich medium [20075862]. | Fission yeast |
