acdh-1 | Acyl CoA DeHydrogenase 1 | RNAi knockdown of acdh-1 starting at hatching or only during the adulthood significantly decreases lifespan of eat-2 without affecting wild-type lifespan. ACDH-1 significantly upregulated in eat-2. Increased content of ACDH-1 is, at least partially, required for lifespan-extension by DR [22810224]. | Nematode |
asp-3 | ASpartyl Protease 3 | RNA interference against asp-3 significantly reduces lifespan of eat-2(ad1116) mutants, without any significant affect on the lifespan of wild-type. Mean and 75%ile lifespan of eat-2 mutants is reduced by 13-14% and 5-9% by asp-3 RNAi. ASP-3 is upregulated in eat-2 mutants [22810224]. | Nematode |
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 |
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 |
HES1 | Homologous to kES1 1 | Deletion of HES1 (alias OSH5) extends replicative lifespan and is non-additive with moderate DR. Elevation of OSH5 levels by an ERG6 promoter reduces mean, median and maximum replicative lifespan by 25, 18 and 29%. HES1 is required for the longevity effect of DR, Perg6-OSH6, Perg6-ERG2 and Perg6-OSH7 (genetic mimetics of DR). Hes1 is upregulated in response to sterol down-regulation including DR. Deletion of OSH5 delays different steps of endocytosis, a sterol-requireing process [Xia et al., unpublished].
Perg6-OSH6 osh5 double mutant have a lifespan significantly shorter than that of Perg6-OSH6 [Xia et al. upublished]. | Budding yeast |
PNC1 | Pyrazinamidase/NiCotinamidase 1 | Cells with 5 copies of PNC1 have a 70% longer replicative lifespan which is cancelled out by SIR2 deletion. PNC1 is upregulated under glucose DR [12736687]. Pnc1 reduces cellular nicotinamide levels, a product and noncompetitive inhibitor of Sir2 deacetylation reaction. Overexpression of PNC1 suppresses the effect of exogenously added nicotinamide on Sir2-dependent silencing at HM loci, telomeres and rDNA loci [12736687; 14729974]. Pnc1 catalyses the breakdown of nicotinamide to nicotinate and ammonia [12736687]. Deletion of PNC1 shortens replicative lifespan approximately by 10% [12736687] and largely prevents replicative lifespan extension of 0.5% glucose restriction. 0.5% glucose restriction slightly extends median replicative lifespan (by 10 - 15%) but not maximum replicative lifespan in pnc1Delta [14724176]. PNC1 overexpression suppresses the inhibitory effect of exogenously added NAM on silencing, lifespan, and Hst1-mediated transcriptional repression [14729974]. Increased expression of PNC1 is both necessary and sufficient for replicative lifespan extension by DR and low-intensity stress. Under non-stressing conditions (2% glucose, 30 degree Celsius), a strain with additional copies of PNC1 (5XPNC1) has 70% longer replicative lifespan than the wild-type and some cells live for more than 70 divisions. Neither DR nor heat stress further increase the lifespan of the 5XPNC1 strain [12736687]. PNC1 deletion decreases chronological lifespan [17110466]. | Budding yeast |
sbds-1 | Shwachman-Bodian-Diamond Syndrome protein homolog 1 | RNA interference of sbds-1 decreases median lifespan by 24% in daf-2 mutants [18006689]. RNAi knockdown of sbds-1 starting at hatching or only during the adulthood significantly decreases lifespan of eat-2 without affecting wild-type lifespan. SBDS-1 are elevated in eat-2 mutants. Increased content of SBDS-1 is, at least partially, required for lifespan-extension by DR [22810224]. | Nematode |
unc-52 | UNCoordinated 52 | RNA interference of unc-52 in adulthood extends mean lifespan by 11% [17411345]. RNAi knockdown of unc-52 starting at hatching or only during the adulthood significantly decreases lifespan of eat-2 without affecting wild-type lifespan. UNC-52 levels are elevated in eat-2 mutants. Increased content of UNC-52 is, at least partially, required for lifespan-extension by DR [22810224]. | Nematode |
