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

    yata yata mutation shortens the maximum lifespan by 68% and results in progressive deterioration of the nervous tissues and aberrant accumulation of Sec23 [19209226]. Fruit fly
    Tsc1 CG6147-PA Tuberous sclerosis complex genes 1 Ubiquitously overexpression of UAS constructs (via the daughterless (da)-GAL-4 driver) containing dTSC1 extends mean lifespan at 29°C by 14% [15186745]. Fruit fly
    S6k RPS6-p70-protein kinase Ubiquitous overexpression of a dominant-negative form of S6k (alias dS6K) increases mean lifespan by 22% and overexpression of a constitutively active form of S6k decreases mean lifespan by 34% at 29°C. Overexpression of a dominant-negative form of S6k protects mutants from deleterious effects of rich food, as if mimicking the effect of DR [15186745]. Fruit fly
    Cbs Ubiquitous or neuron-specific transgenic overexpression of Cbs enhances longevity in fully-fed animals. Cbs RNAi partially abrogates increased lifespan by DR, but has no effect on fully fed animals. Cbs upregulation is required for increased lifespan under low-nutrient conditions. Response of male flies to DR is muted in comparison with females. Adult-specific ubiquitous expression of Cbs is sufficient to increase female mean and maximum lifespan by 12 - 43% and 10%, respectively. Males, whose lifespan is relatively less affected by DR, exhibite a smaller, but still significant increase in lifespan by 7% upon Cbs overexpression. Neuronal overexpression also increases lifespan, albeit modestly (approximately 12% mean and 15% maximum lifespan extension), whereas overexpression in the fat body and in the gut has no effect [21930912]. Fruit fly
    rut rutabaga Two rutabaga mutants, rut1 and rut2080, have significantly shortened lifespans [17369827]. Fruit fly
    Trx-2 thioredoxin-2 Trx-2 mutants have a 25% reduction in maximum lifespan and exhibit lower tolerance to oxidative stress while animals carrying multiple copies of Trx-2 exhibit higher tolerance [17567437]. Fruit fly
    PDTC Pyrrolidine dithiocarbamate Treatment of Drosophila imago with PDTC increases median (by 11-13%) and maximum (by 11-14%) lifespan in females and males, respectively [22661237]. Fruit fly
    LY294002 Treatment of Drosophila imago with 5 micromolar LY294002 increases median (by 14%) and maximum (by 16-22%) lifespan (p<0.001) in females and males, respectively [22661237]. Low dose of LY294002 (5 microM) slightly increase the median and maximum lifespan of fruit fly [20017609]. Fruit fly
    Spargel Tissue-specific overexpression of dPGC-1 in stem and progenitor cells within the digestive tract of females flies extends the mean and maximum lifespan of females by up to 33% and 37%. Those mutants display a delay in the onset of aging-related changes in the intestine, leading to improved tissue homoeostasis in old flies [22055505]. Fruit fly
    tim timeless TIMELESS (TIM) oscillation are attenuated in the cerebral clock neurons of elderly flies [23223368]. Tim01 mutants have nearly a 50% reduced fecundity [14667147]. Fruit fly
    Edem1 The mean lifespan of Edem1 mutants of both male and female is increased by more than 30% [19302370]. Fruit fly
    ovo The dominant ovoD1 allele extends female lifespan by approximately 50%. It does not synergize or prevent life-extension caused by chico [10617470; 11292874]. ovoD1 mutants are sterile [Mevel-Ninio et al. 1991]. Fruit fly
    kermit The disruption of kermit (alias dGIPC) function results in premature loss of locomotor activity and reduced mean lifespan [21029723]. Fruit fly
    Tequila Tequila exhibits a coding region difference unique to animals under experimental evolution selected for longevity [23106705]. Tequila is upregulated with age and microbial infection, while downregulated with oxidative stress [11095759; 17196240; 15475297]. Fruit fly
    Ten-a Tenascin accessory Ten-a exhibits a coding region difference unique to animals under experimental evolution selected for longevity and is differentially expressed in the head in for longevity selected lines [23106705]. Fruit fly
    Surf1 surfeit gene 1 Surf1 knockdown results in larval lethality. However, knockdown in the central nervous system (CNS) not only bypasses the larval lethality but it results in an increase in maximum lifespan of about 20-30% [16172499]. Fruit fly
    sun Stunted sun mutations increases lifespan and resistance to oxidative stress [15133470] Fruit fly
    Cat Catalase Simultaneous overexpression of catalase and Sod1 results in a one-third (i.e. 30%) lifespan extension, a slower rate of mortality acceleration, and a delayed loss in physical performance, but neither has any effect on lifespan alone [8108730]. Targeted overexpression of CAT in the mitochondrial matrix has no effect on lifespan at 25 degree Celsius, slightly shortens lifespan at 29 degree Celsius as is associated with increased resistance to endogenous hydrogen peroxide, paraquat, and cold stress [12521602]. Fruit fly
    Sod1 Superoxide dismutase Simultaneous overexpression of catalase and Sod (alias Sod1) results in a one-third lifespan extension, a slower rate of mortality acceleration, and a delayed loss in physical performance, but neither has any effect on lifespan alone [8108730]. General overexpression of Sod (also known as Cu/ZnSOD) alone is sufficient to extend lifespan by up to 48%. Simultaneous overexpression of catalase with Cu/ZnSOD has no added benefit, presumably due to a pre-existing excess of catalase [9858546]. Sod1 reduction by knockdown or knockout blunts the lifespan extension by a high sugar-low protein diet, but not a low-calorie diet [22672579]. Sod mutant flies display infertility and a reduction in lifespan [2539600]. Fruit fly
    sgg shaggy Several insertions of P-based vectors in the structural part of sgg are associated with alterations of male and female lifespan [22661237]. Fruit fly
    SdhB Succinate dehydrogenase B SdhB mutants are hypersensitive to oxygen and displays signs of premature aging, including a 66% decrease in mean lifespan and a 17% decrease in maximum lifespan [17056719]. Fruit fly
    CG5389 RNAi of complex V subunit CG5389 results in increased mean longevity under standard laboratory food conditions (3% yeast) in males. RNAi started from the development results in a mild lifespan increase in both sexes (3-11% in females and 3-8% in males). Post-developmental RNAi and silencing limited to neurons has variable effects with reduction in lifespan of up to 9% [19747824]. Under rich media conditions CG5389 knockdown throughout development and adulthood increases mean lifespan by 26% and abolished the lifespan extension by DR (started in the adulthood) in males. Suppression of CG5389 only during the adulthood either via RNAi by tub-GS or via oligomycin (a specific inhibitor of complex V) feeding prevents an increase in longevity under DR (started in the adulthood) in males [19968629]. Fruit fly
    CG18809 RNAi of CG18809 results in a 7-19% increase in mean lifespan of females, while neural RNAi results in an increased mean lifespan of up to 12% in females. For males the results are variable [19747824]. Fruit fly
    CG17856 RNAi of CG17856 results in an increase in mean lifespan of 13-18% in females. In the case of males and post-developmental experiments the results are variable [19747824]. Fruit fly
    CG9172 RNAi against CG9172 increases mean lifespan in females by up to 4-12% when applied in both development and adulthood, and up to 46% when applied in adult neurons only. For males the effect is variable [19747824]. Fruit fly
