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

    LAT1 LAT1 is suggested to play a role in lifespan extension of DR. Deleting LAT1 abolishes replicative lifespan extension induced by 0.5% and 0.05% glucose restriction. 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. Budding yeast
    SCH9 Transposon-mediated mutagenesis of SCH9, which encodes for a serine threonine kinase homologous to Akt/PKB, increases resistance to oxidants and thermal stress as well as extends chronological lifespan by 30%. SCH9 deletion increases chronological lifespan by up to threefold. Stress-resistance transcription factors Msn2/Msn4 and protein kinase Rim15 are required for this life-extension. Deletion of the mitochondrial antioxidant enzyme superoxide dismutase gene SOD2 prevents the increased chronological lifespan caused by SCH9 deletion [11292860]. Mutations that decrease the activity of the Ras/Cyr1/PKA pathway also extend longevity and increase stress resistance by activating transcription factors Msn2/Msn4 and Sod2 [12855292]. SCH9 deletion mutants exhibit more than 3-fold extension of chronological lifespan. By day 9 of medium depletion all the wild-type cells were dead while 50% sch9 mutants survived [17710147]. Deletion of SCH9 also increases resistance to heat shock and oxidative stress [11292860], and increases replicative lifespan by 18% (in DBY746) [12586694]. SCH9 deletion increases the replicative lifespan by 40% in the alpha strain [18340043] and increases mean chronological lifespan by 97 - 246% (97, 133, 154, 226, 246) in diploid cells [21447998]. Mutation or deletion of SCH9 increases resistance to oxidants and extends chronological lifespan [11292860; 16286010]. The extended lifespan of SCH9 deletion mutants is not further extended by low glucose DR and is independent of Sir2 [16293764]. Deletion of RIM15 or GIS1 reverses chronological lifespan extension associated with sch9Delta. Water restriction further increases chronological lifespan of sch9Delta [18225956]. Deletion of SCH9 results in a longer chronological lifespan [21076178]. Budding yeast
    SWH1 SWH1 (alias OSH1) deletion mutants have an extended replicative lifespan (p=0.02) and DR does not increase the long lifespan of SWH1 deletion mutants [Xia et al. unpublished]. Budding yeast
    YDL180W YDL180W deletion impairs DR-mediated replicative lifespan extension, but does not change lifespan on AL significantly [22912585]. Budding yeast
    ADE4 ADEnine requiring 4 ade4 mutation extends chronological lifespan, but not replicative lifespan, and is non-additive with 0.5% glucose or amino-acid DR on chronological lifespan extension. ADE4 deletion in atg16 mutants results only in a partial extension of the chronological lifespan by 0.5% glucose DR [20421943]. Budding yeast
    AIM4 Altered Inheritance rate of Mi 4 AIM4 (alias SOY1) deletion increases chronological and replication lifespan, which is non-additive with DR. On AL mean and maximum replicative lifespan are extended by 63 and 69%, respectively. DR appears to decrease aim4-induced replication lifespan extension, indicating a negative interaction. aim4 mutation does not change DR-induced chronological lifespan extension [21584246]. Budding yeast
    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
    AAT1 Aspartate AminoTransferase 1 Overexpression of AAT1 extends replicative lifespan by 25% and does not synergize with 0.5% glucose restriction [18381895]. Budding yeast
    ATG10 AuTophaGy related 10 ATG10 deletion cancels out replicative lifespan extension by DR [18690010]. Budding yeast
    ATG11 AuTophaGy related 11 ATG11 deletion extends replicative lifespan under AL and abrogates DR-lifespan extension [18690010]. Budding yeast
    ATG15 AuTophaGy related 15 Deletion of ATG15 does not affect the lifespan significantly on AL, while DR shortens replicative lifespan of ATG15 deletion mutant by 28% [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
    ATG17 AuTophaGy related 17 ATG17 deletion decreases replicative lifespan under AL and blocks DR-lifespan extension. ATG17 mutant's replicative lifespan decreases by 70% on DR [18690010]. Budding yeast
    ATG2 AuTophaGy related 2 ATG2 deletion prevents chronological lifespan extension induced by amino-acid DR [20421943]. Budding yeast
    BMH1 Brain Modulosignalin Homologue 1 Deleting BMH1 extends chronological lifespan by 25% and is associated with activated stress response, decreased ROS levels and increased heat-shock-element-driven transcription activity. BMH1 deletion was non-additive with the genetic DR mimetic cdc25 and tor1. Water starvation (a form of extreme DR) extends chronological lifespan of BMH1 mutant even more as it does in wild-type. BMH1 genetically interacts with DR as well as TOR- and PKA-signaling pathways to regulate lifespan. Phosphorylation of Ser238 on Bmh1 increases during chronological aging, which is delayed by DR or reduced TOR activity [19805817]. Budding yeast
    CDC25 Cell Division Cycle 25 The CDC25-10 allele extends mean and maximum replicative lifespan by 34% and 18%, respectively, at 30 degree Celsius. cdc25-10 mutants have an extended replicative lifespan under AL. Growth on 0.5% glucose restriction does not further extend replicative lifespan of cdc25-10 mutants. CDC25 null mutant is not viable. CDC25 appears to act in the same genetic pathway as SIR2 and NPT1 and is suggested to be genetic model of DR [11000115]. Budding yeast
    CYR1 CYclic AMP Requirement 1 The CDC35-1 allele of the adenylate cyclase CYR1 confers a 75% extension of replicative lifespan at 25 degree Celsius [11000115]. Transposon-mutagenized CYR1 increases resistance to oxidants and extends chronological lifespan by up to 90%. Stress-resistance transcription factors Msn2/Msn4 and protein kinase Rim15 are required for this lifespan extension [11292860]. CYR1 mutation is assumed to act as genetic DR mimetic [11000115]. The CDC35-1 allele of the adenylate cyclase CYR1 confers a 75% extension of replicative lifespan at 25 degree Celsius [11000115]. cyr1-1 mutation extends median chronological lifespan by 28-47% and is non-addative with lifespan extension conferred by overxpression of human MAPK1 [17662940]. 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
    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
    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
    ERG5 ERGosterol biosynthesis 5 Deletion of ERG5 decreases replicative lifespan by 35% in the a strain [18340043], but increases mean chronological lifespan by 26 - 116% (26, 40, 43, 62, 116) in diploid cells [21447998]. Deletion of ERG5 cancels out the replicative lifespan extension of 0.5% glucose restriction [18690010]. Budding yeast
    ERG6 ERGosterol biosynthesis 6 Deletion of ERG6 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
    FRE6 Ferric REductase 6 FRE6 deletion increases mean replicative lifespan by 14% and cancels out the lifespan extending effect of DR [22912585]. 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
    FKH1 ForK head Homolog 1 Deletion of FKH1 or FKH2 has no effect on neither replicative, nor chronological lifespan [18225956]. Deletion of both FKH1 and FKH2 reduces mean chronological lifespan by 50% and abrogates lifespan extension and increased stress resistance conferred from water starvation (extreme DR). Modest increase in FKH1 or FKH2 expression results in a slight increased chronological and replicative lifespan as well as stress resistance [22438832]. Budding yeast
