| AVT1 | Amino acid Vacuolar Transport 1 | Overexpressing or deleting AVT1 is sufficient to extend or shorten replicative lifespan, respectively [23172144].
Overexpression of AVT1 prevents mitochondrial dysfunction, prevents alterations in mitochondrial structure and ΔΨ of aged cells even through the vacuolar acidity is reduced in these cells. AVT1 overexpression extends the mean, median and maximum replicative lifespan by 28, 28, and 22%, respectively [23172144].
Deletion of AVT1 accelerates the development of age-induced mitochondrial dysfunction without effecting the kinetics of vacuolar acidity decline and prevents the suppression of mitochondrial dysfunction by VMA1 and VPH2 overexpression without affecting vacuolar acidity. AVT1 deletion decreases mean, median and maximum replicative lifespan by 21, 22, and 12%, respectively [23172144]. | Budding yeast |
| OSH2 | OxySterol binding protein Homolog 2 | Deletion of OSH2 decreases mean chronological lifespan [20657825]. | Budding yeast |
| VAC14 | VACuole morphology and inheritance mutant 14 | VAC14 mutants have a single vacuole and shortened lifespan on normal media [16293764]. | Budding yeast |
| TEC1 | Transposon Enhancement Control 1 | Tec1 is a positive regulator of chronological lifespan. Absence of TEC1 causes a significant shortened chronological lifespan, but does not block chronological lifespan extension by rapamycin. TEC(AxY) mutation also reduces chronological lifespan, although not so pronounced as strains lacking TEC1. Rapamycin-induced chronological lifespan extension is almost completely blocked by TEC(AxY) allele [21840851]. | Budding yeast |
| NTH2 | Neutral TreHalase 2 | Deletion of NTH2 shortens mean chronological lifespan by 39% (at 30 degree Celsus in BY4742) [22783207].
NTH2 mutant cells have elevated trehalose concentration before they enter the non-proliferative stationary growth phase which remained high during the stationary phase. NTH2 deletion cells have no altered ROS levels in pre-quiescent cells [22783207]. | Budding yeast |
| TPS1 | Trehalose-6-Phosphate Synthase 1 | Deletion of TPS1 decreases intracellular trehalose concentration and shortens the mean chronological lifespan by 74% (at 30 degree Celsus in BY4742) [22783207]. | Budding yeast |
| ESA1 | — | esa1-531 mutant has an even shorter chronological lifespan than PKA1 deletion mutant in both 2% glucose (ad libitum) and water (extreme DR) at 30 degree Celsius, a semipermissive temperature. At the permissive temperature (25 degree Celsius) there is little difference [19303850]. | Budding yeast |
| ACH1 | Acetyl CoA Hydrolase 1 | ACH1 deletion cells accumulate a high amount of extracellular acetic acid and display a reduced mean and maximum chronological lifespan. Maximum lifespan is reduced by 32%. Lifespan shortening is completely abrogated by alleviating the acid stress either by a DR regimen that prevents acetic acid production or by transferring chronologically aging mutant cells to water. Deletion of ACH1 is accompanied by reactive oxygen species accumulation, severe mitochondrial damage, and an early insurgence of apoptosis [22754872]. | Budding yeast |
| SWI4 | SWItching deficient 4 | Deletion of SWI4 shortens replicative lifespan by approximately 90% [11805047]. SSD1-V partially suppresses the short lifespan of a swi4 mutant.
Mutation of swi4 results in slow growth and temperature sensitivity, both of which are suppressed by SSD1-V [11805047]. | Budding yeast |
| SUN4 | — | Disruption of SUN4 shortens mean (87.5% of normal), but not maximum, replicative lifespan in BKY1-14c [Austriaco, N.R. (1996) âUTH1 and the Genetic Control of Aging in the Yeast, Saccharomyces cerevisiae.â Ph.D. Thesis, Massachusetts Institute of Technology; 8810036]
SUN4 mutation causes failure of daughter cells to completely detach and results in a multi-budded morphology [10683261]. | Budding yeast |
| SIM1 | Start Independent of Mitosis 1 | Disruption of SIM1 shortens mean (87.5%), but not maximum, lifespan without causing any other gross changes in cell cycle parameter or growth characteristics [8810036].
Cells bearing deletions in CLB1-4 are unable to undergo mitosis and normally arrest in G2. SIM1 disruption in clb1-4 mutant backgrounds will allow a second round of DNA synthesis without mitosis [8574583]. sim1delta;uth1delta double mutants exhibit various defects, including binucleated cells, benomyl sensitivity, heat shock sensitivity, inability to store glycogen, sensitivity to starvation and failure of spores to germinate [10612745]. | Budding yeast |
| RSR1 | RaS-Related 1 | Deletion of RSR1 (alias BUD1) shortens replicative lifespan [9789734]. | Budding yeast |
| POL1 | POLymerase 1 | Mutation of POL1 results in a 20-60% reduction in mean lifespan (in SS111) [12024027] | Budding yeast |
| NNT1 | Nicotinamide N-methylTransferase 1 | Deletion of NNT1 decreases mean and maximum lifespan by 9 and 19%. 0.5% glucose DR extends the mean and maximum lifespan of NNT1 deletion mutants by 35 and 40%. 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 overexpression increases rDNA silincing, whereas deletion decreases rDNA silencing. Overexpression of human nicotinamide N-methyltransferase also increases rDNA silencing [12736687]. | Budding yeast |
| NCA3 | Nuclear Control of ATPase 3 | Disruption in NCA3 shortens mean (87% of normal), nut not maximum replicative lifespan without causing any other gross changes in cell cycle parameters of growth characteristics [8810036].
In combination with an NCA2 disruption, NCA3 disruption causes a cryosensitive phenotype on non-fermentable carbon sources due to a defect in the F1-F0 ATP synthetase due to misbalancing of alternate spliceforms of mitochondrial mRNA encoding subunits 6 and 8 of the synthase [7586026]. | Budding yeast |
| HSC80 | — | Deletion of HSC82 has no effect on replicative lifespan, but shortens chronological lifespan [11361336]. | Budding yeast |
| HOG1 | High Osmolarity Glycerol response 1 | Deletion of HOG1 shortens replicative lifespan by 25% and prevents lifespan extension by high osmolarity [12391171]. HOG1 is required for many of the transcriptional responses to high osmolarity, including increased glycerol biosynthesis and MSN2/4-dependent stress response [10722658]. HOG1 deletion slightly decreases chronological lifespan and partially suppresses the premature aging phenotype and short lifespan of ISC1 deletion [22445853]. | Budding yeast |
| HAP5 | Heme Activator Protein 5 | Deletion of HAP5 shortens replicative lifespan by approximately 40%. This is not a premature aging phenotype as "old" HAP5 cells do not become premature sterile or exhibit other biomarkers of yeast aging [9271578]. HAP5 null mutants are unable to grow on a non-fermentable carbon source [7828851]. | Budding yeast |
| GPD1 | Glycerol-3-Phosphate Dehydrogenase 1 | GPD1 deletion shortens replicative lifespan by 25% and prevents lifespan extension by high osmolarity [12391171]. Transcripational regulation of GPD1 by osmotic stress requires HOG1 [8196651]. | Budding yeast |
| COQ3 | COenzyme Q 3 | Deletion of COQ3 decreases chronological lifespan and renders cells respiratory deficient and sensitive to hydrogen peroxide [12586694]. | Budding yeast |
| CDC7 | Cell Division Cycle 7 | Transient inactivation of CDC7 results in a shortened replicative lifespan [2698814]. CDC7 participates in silencing and RAS2 modulates its activity [1990268]. | 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 |
| 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 |
| YOL092W | — | Deletion of YOL092W decreases mean and maximum replicative lifespan by 36 and 21%, respectively. Lifespan of YOL092Y deletion mutants is extended by 0.5% glucose restriction [22912585]. | Budding yeast |
| VPS20 | Vacuolar Protein Sorting 20 | VPS20 deletion decreases mean and maximum replicative lifespan by 16% and 19%, respectively, and additionally cancels out the DR-induced replicative lifespan extension [22912585]. | Budding yeast |
