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

    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

    RPS6B RPS6B deletion increases mean replicative lifespan by about 30% [16293764]. Deletion of RPS6B, but not of the RPS6A paralog increases replicative median lifespan robustly by 45% [17174052]. Budding yeast
    YSC84 Deletion of YSC84 increases replicative lifespan by 20% in the alpha strain [19030232]. YSC84 deletion increases replicative lifespan by 25% in the alpha strain [18340043]. Budding yeast
    age-2 Homocygous age-2 mutation increases mean (+43%, +31%, +38%) and maximum (+29%, +36%, +18%)) lifespan by about 20%. age-2 mutant exhibit normal motility, slightly higher swimming rates, reduced fertility and somewhat longer development times and slightly larger size at the first egg laying. Lifespan is extended by reducing the initial mortality rate. age-2 mutation complements other aging gene mutations such as age-1, daf-2, spe-26, clk-1, clk-3 and gro-1. A age-1 age-2 double mutant lives longer than animals with individual mutations and exhibits a longer lifespan at 25 degree Celsius than at 20 degree Celsius [10219000]. Nematode
