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

    IFNG interferon, gamma The distribution of 874T/A polymorphism in the IFNG gene was examined in 174 Italian centenarians (>99 years old, 142 women and 32 men) and 248 <60-year-old control subjects (90 women and 158 men). The +874T allele, known to be associated with low IFN-gamma production, was found less frequently in centenarian women than in centenarian men or in control women whereas no significant differences were observed in the distribution of the two alleles between male or female controls. Allele frequencies in centenarian men were not found significantly different from male controls [11772518].IFNG was found to be associated with longevity [21299522].

The -1082G homozygous genotype, associated with high IL-10 production, was increased in centenarian men but not in centenarian women. No difference was found between centenarians and control subjects regarding the other two SNPs [11857058].IL10 was found to be associated with longevity [20518833].

    Sybu syntabulin (syntaxin-interacting) Sybu is transcriptional downregulated in the cerebral cortex at the age 28 months under different longevity conditions such as under dietary restriction (DR) as well as in feeding switch regimens that result in extended lifespan, like early age switch to DR as well as the reverse switch under the influence of the DR-mimetic α-lipoic acid (i.e. DR switched to ad libitum+ lipoic acid) [Shona et al. 2013]. Norway rat
    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
    Srf Serum Response Factor SRF is activated by the daily variations of a blood signal, resulting in significant changes in the structure and size of live cells throughout the course of the day [23374345]. Daily variations of plasma signal cyclically stimulates SRF. SRF is solicited in an antiphasic manner in humans and rats, a fact that is linked to their activity, diurnal and nocturnal, respectively. SRF activation is accompanied by a remodeling of the cellular "skeleton", resulting in morphological change in cells based on their activity [23374345]. House mouse

    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
    APOC3 apolipoprotein C-III Several small nucleotide polymorphisms in the APOC3 gene were associated with longevity [8018664; 11193221; 16602826]. The Sst I polymorphism was examined in 179 Finnish centenarians. The S2 allele (Sst I restriction site present) occurred more often in the centenarians (frequency, 12.9%) than in the youngest reference population (frequency, 8.8%) [8018664]. Human
    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
    Sod2 Superoxide dismutase 2 (Mn) RNA interference of Sod2 results in increased oxidative stress and early-onset mortality in young adults [12456885]. Overexpression of Sod2 by 5-115% decreases lifespan by 4-5% without any compensatory changes in metablic rate, level of physical activity, or the levels of other antioxidants (Sod, Cat, and glutathione) [10545213]. Targeted overexpression of Sod2 in motor neurons alone extends lifespan by 30% [11113599]. Induced overexpression of Sod2 in adult animals extends lifespan up to 37% [12072463]. Overexpression of catalase in combination with SOD2 has no added benefit for lifespan [12072463]. Animals overexpressing SOD2 or catalase do not exhibit a decrease in metabolism as measured by oxgen consumption [12072463]. Sod2 overexpression results in a 20% increase in mean and maximum lifespan [18067683]. Fruit fly
    Mlp84B Muscle LIM protein at 84B RNA interference of Mlp84B specifically in the heart results in bradycardia and heart rthym abnormalities as well as a shorter mean lifespan in males but not in females [18083727]. Fruit fly
    l(3)neo18 lethal (3) neo18 RNA interference of l(3)neo18 in females increases mean lifespan by 14-18% when applied during development and adulthood in the whole organism and by 8-24% when applied in the neurons. The effect is more variable in males. A consistent increase (8-18%) is however observed for whole organisms RNAi in adults [19747824]. l(3)neo18 (alias CG9762) is translational upregulated upon DR. Under rich nutritional conditions lifespan of l(3)neo18 RNAi knockout animals is indistinguishable from wild-type, while upon DR, lifespan extension is diminished in males and females [19804760]. Fruit fly
    Akt1 CG4006 gene product from transcript CG4006-RA RNA interference of Akt1 in intestinal stem cells, results in impaired regeneration of the intestinal epithelium and a short lifespan. In males and females on mean lifespan is 11.4% and 7.4% lower [20976250]. Fruit fly
    RIMBP2 RIMS binding protein 2 RIMBP2 was found to be associated with longevity [22174011]. Human
    rho-7 rhomboid-7 rho-7 knockout flies have severe neurological defects and a much reduced lifespan [16713954]. Fruit fly
    Loco locomotion defects Reduced expression of Loco due to hetero-deficient results in a 17-20% longer mean lifespan for both male and females, besides the fact that the homozygous deficiency of loco is lethal. Several of these long-lived mutants are more resistant to stresses such as starvation, oxidation and heat. Additionally, mutants have higher Manganese-containing superoxide dismutase (MnSOD) activity, increased fat content an diminished cAMP levels. Loco's RGS domain is required for the regulation of longevity as deletion analysis suggest [21776417]. Fruit fly
    Factors are an extension of GenAge and GenDR.
