Factors

We need to know every factor which determines lifespan.

Lifespan factors often but not always originate from defined genetic elements. They are not just genes, by definition they can be anything for which a Classifications schema can be build for that is related to the regulation of lifespan, such entities may include Single-Nucleotide Polymorphism, transcript variants, proteins and their complexes, compounds (i.e. small molecules like metabolites and drugs), etc. A factor should be based on a defined molecular entity or genomic position and been classified. It shall be highly flexible and scalable Concept.

While individual lifespan factors within each species or precise defined molecular entities will be captured within the Lifespan App, Data Entries of the Data App may summarize for instance the relevance of each factor class (e.g. homologous group; chemical derivate of related structure and properties, etc.) as well as draw overall conclusions. o

    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
    HPR1 HyPerRecombination 1 Deletion of HPR1 decreases replicative lifespan [11756539] Budding yeast
    OSH7 OxySterol binding protein Homolog 7 Overexpression of OSH7 extends mean replicative lifespan. PERG6-OSH7 does not extend the maximum lifespan significantly [Xia et al., unpublished]. Deletion of the CC domain of Osh7 (Perg6-OSH7-ORD) greatly shortens the lifespan. Deletion of the Osh7's CC domain decreases lifespan (Perg6-OSH7-ORD) shortens the lifespan [Tang et al., personal communication]. Osh7 interacts with the late endosome ATPase Vps4 by their C-terminal coiled-coil (CC) domain. 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
    GTR1 GTp binding protein Resemblance 1 GTR1 deletion decreases mean and maximum replicative lifespan under AL by 36 and 51%, respectively, and cancels out the lifespan extending effect of DR [22912585]. Budding yeast
    DAP2 Dipeptidyl AminoPeptidase 2 DAP2 deletion decreases mean and maximum replicative lifespan under AL by 19 and 36%, respectively, and cancels out the lifespan extending effect of moderate DR [22912585]. Budding yeast
    ERG2 ERGosterol biosynthesis 2 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]. Perg6-ERG2 does not extend the lifespan significantly on normal medium, but it reverses the effect of DR. DR greatly shortens the lifespan of Perg6-ERG2 mutants. Perg6-ERG2 shortens the lifespan of nyv1 deletion mutations [Xia et al. unpublished]. Deletion of OSH5 greatly shortens the lifespan of Perg6-ERG2. SIR2 overxpression extends the lifespan of Perg6-ERG2 [Xia et al. unpublished]. Budding yeast
    CCR4 Carbon Catabolite Repression 4 Deletion of CCR4 increases mean chronological lifespan by 20 - 41% (20, 33, 41) in diploid cells [21447998]. In W303R CCR4 deletion shortens replicative lifespan by approximately 80% and results in temperature sensitivity that is suppressed by SSD1-V. SSD1-V partially suppresses the short-lifespan of ccr4 mutant. CCR4 mutation is synthetically lethal in combination with deletion of MPT5 in the absence of SSD1-V [11805047]. Budding yeast
    ACO1 ACOnitase 1 Deletion of ACO1 decreases mean chronological lifespan by 42 - 56% in diploid cells [21447998]. Budding yeast
    RPL6A Ribosomal Protein of the Large subunit 6A Deletion of RPL6A decrease mean replicative lifespan by 25% in the alpha strain [18340043; 18423200], but increases mean replicative lifespan by 40% in the remade strain. Its deletion non-significantly increases mean replicative lifespan in the ORF collection [22377630]. Budding yeast
    BMH2 Brain Modulosignalin Homologue 2 Overexpressing 14-3-3 protein, Bmh2, significantly extends median chronological lifespan by activating stress response [19805817]. Budding yeast
    KES1 KrE11-1 Suppressor Deletion of OSH4 decreases mean replicative lifespan by 18% [Xia et al., unpublished]. Budding yeast
    OSH6 OxySterol binding protein Homolog 6 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. Deletion of the CC domain leads Osh6 to the late endosome. [Fusheng Tang, personal communication]. OSH6 deletion does not affect lifespan under normal conditions, but it abrogates the lifespan extension by 0.5% glucose restriction [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
    SRX1 SulfiRedoXin 1 Extra copy of SRX1 counteracts age-related hyperoxidation of Tsa1 and extends replicative lifespan by 15 - 20% in a TSA1-dependent manner. Replicative lifespan extension in sir2;fob1 double mutant by DR is reduced by SRX1 deletion. Wild-type cells require SRX1 to fully extend lifespan. DR fails to further extend replicative lifespan of cells carrying an extra copy of SRX1. Mutation in CDC35 (adenylate cyclase), a genetic mimetic of DR, is dependent on SRX1 to extend replicative lifespan [21884982]. Budding yeast
    GTS1 Glycine Threonine Serine repeat protein 1 Deletion or overexpression of GTS1 shortens replicative lifespan significantly and slightly, respectively (wt:26, Delta:16 and OE:24) [8573138]. Budding yeast
    TSA1 Thiol-Specific Antioxidant 1 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]. Disruption of TSA1 shortens chronological lifespan [15129730]. Replicative lifespan extension by DR in sir2;fob1 double mutant is reduced by TSA1 deletion mutant. Wild-type cells require TSA1 to fully extend lifespan. Mutation in CDC35 (adenylate cyclase), a genetic mimetic of DR, is dependent on TSA1 to extend lifespan [21884982]. Budding yeast
    ATG7 Autophagy-related protein and dual specificity member of the E1 family of ubiquitin-activating enzymes; mediates the conjugation of Atg12p with Atg5p and Atg8p with phosphatidylethanolamine, required steps in autophagosome formation ATG7 deletion reduces chronological lifespan by 70% [19302372]. Budding yeast
    ATG1 AuTophaGy related 11 ATG1 deletion reduces chronological lifespan by 70% [19302372]. Deletion of ATG1 reduces replicative lifespan by 20% in the alpha strain [18340043]. Budding yeast
    ZDS2 Zillion Different Screens 2 Deletion of ZDS2 decreases replicative lifespan by about 20% [10662670]. ZDS2 null mutation decreases rDNA silencing five-fold, increases silencing at a mutant HMR that lacks the Rap1-binding site in the HNR-E silencer three-fold, and has no effect on telomeric silencing. ZDS2 deletion decreases rDNA silencing, increases rDNA recombination, and increases level of phosphorylated Sir3 [10662670]. Budding yeast
    YUH1 Yeast Ubiquitin Hydrolase 1 Deletion of YUH1 decreases replicative lifespan decreased 30% in the alpha strain [18340043]. Budding yeast
    YPT7 Yeast Protein Two 7 YPT7 deletion decreases replicative lifespan by 15% in the alpha strain [18340043]. Deletion of YPT7 cancels out replicative lifespan extension of 0.5% glucose restriction and results under DR also into a shorter replicative lifespan than under AL [18690010]. Budding yeast
    YPR011C Deletion of YPR011V decreases replicative lifespan by 20% in the a strain [18340043]. Budding yeast
