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

    mrpl-37 Knockdown of mrpl-37 increases lifespan by 41% [23698443]. Nematode
    mrpl-2 Knockdown of mrpl-2 increases lifespan by 54% [23698443]. Nematode
    mrpl-1 Knockdown of mrpl-1 increases lifespan by 57% [23698443]. Nematode
    ttll-9 Tubulin Tyrosine Ligase Like Knockdown of ttll-9 throughout the entire life increases the lifespan by 3% [23698443]. Nematode
    nkcc-1 Na-K-Cl Cotransporter homolog Knockdown of nkcc-1 throughout the entire life increases the lifespan by 23% [23698443]. Nematode
    mrps-5 Knockdown of mrps-5 throughout the entire life increases the lifespan by 60%. mrps-5 RNAi prevents aging-associated functional decline and alters mitochondrial function. Knocking down mrps-5 after early development no longer affects nematode lifespan. When RNAi of mrps-5 was performed during the larval stages only, lifespan increases by 48%, whereas RNAi started from the L4 stage has no effect. mrps-5 RNAi results in fragmented mitochondria. mrps-5 RNAi increases lifespan by 40% in widltype, 37% in daf-16(mu86), 40% in sir-2.1(ok434) 69% in aak-2(ok524) and 112% in mev-1(kn1). Knockdown of cco-1 does not extend the lifespan of mrps-5 RNAi [23698443]. Nematode
    mir-277 Constitutive miR-277 expression shortens lifespan and synthetically lethal with reduced insulin signaling, indicating that metabolic control underlies this phenotype. Transgenic inhibition with a miRNA sponge construct also shortens lifespan [23669073]. miR-277 is downregulated during adult life [23669073]. mir-277 controls branched-chain amino acid catabolism and as a result it can modulate the activity of TOR kinase [23669073]. Fruit fly
    snz snazarus Mutation in snz increases maximum lifespan of both sexes by up to 66%, while the median female lifespan is approximately 85% higher and that of males around 72% [18478054]. 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
    Lnk Loss of Lnk function results in increased median (14% in females and 17.5 in males) and maximum lifespan, reduced female fecundity and improves survival under conditions of oxidative stress and starvation. Heterozygousity does not result in any significant differences in lifespan in either males or females. Moreover, lifespan extension in one of the female homozygous mutant is fully rescued by the introduction of a Lnk genomic rescue construct [20333234]. Fruit fly
    LBR Lamin B receptor Overexpression of Lamin B receptor in the adult muscle and in the abdominal fat body results in a 54% and 46% reduction of mean lifespan, respectively [18494863]. Fruit fly
    kuk kugelkern Overexpression of kugelkern in the adult muscle results in a 60% reduction of mean lifespan [18494863]. Fruit fly
    CG3776 Both overexpression and underexpression of CG3776 (alias Jhebp29) reduces the mean lifespan, where the reduction in males is slightly higher. The lifespan of male flies with under- and overexpressed CG3776 is reduced by 38.8 and 42.6%, respectively when compared with Oregon R flies.The lifespan of female flies with under- and overexpressed CG3776 is reduced by 31.6 and 35%, respectively when compared to Oregon R flies. Among the males and females, relatively to Oregon R and EP835/CyO, the age-specific survival of EP835/EP835 and EP835/Gal4 is reduced in both log-rank and Wilcoxon tests (P < 0.001); survival of EP835/EP835 and EP835/Gal4 differed using the log-rank-test (male: P<0.001; female: P=0.027) [18275960]. Fruit fly
    Gr63a Gustatory receptor 63a Gr63a loss-of-function in female flies leads to 30% extended mean lifespan, increased fat deposition, and enhanced resistance to some (but not all) environmental stresses. Lifespan of males is not extended [20422037]. Overexpression of Gr63a has modest negative effect on lifespan [20422037]. Fruit fly
    esc extra sexcombs Males heterozygous for the null esc4 or the dominant negative esc9 mutation that are progeny of an out-cross to a O-R wild-type strain have median lifespan that is, respectively, 47% and 60% longer than the O-R control. When derived from an out-cross to a longer-lived C-S wild-type strain, heterozygous esc9 flies have a median lifespan that is 43% longer than the C-S control [20018689]. Fruit fly
    Edem1 The mean lifespan of Edem1 mutants of both male and female is increased by more than 30% [19302370]. Fruit fly
    E(z) Enhancer of zeste Flies heterozygous for the protein null E(z)63 or the catalytically inactive E(z)731 mutation that are progeny of an out-cross to an Oregon-R (O-R) wild-type strain exhibit a substantially greater median lifespan than the O-R control (71% and 76%, respectively). When derived from an out-cross to a longer-lived Canton-S (C-S) wild-type strain, the median lifespan of E(z)63 heterozygous is 33% longer than the C-S control [20018689]. Fruit fly
    DNApol-gamma35 DNA polymerase gamma 35kD Overexpression of DNApol-gamma35 (DNA polymerase gamma) in the nervous system results in a decrease in the median lifespan ranging from 39% to 52% [17999718]. 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
    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
    alpha-Man-I alpha Mannosidase I alpha-Man-I mutant fly exhibit enhanced resistance to paraquat and starvation an a 60% increase in mean lifespan for both sexes. After outcrossing, the mutant exhibit, under normal conditions, an increase in mean lifespan of 22% for females and 38% for males. Maximum lifespan is increased by 15%. alpha-Man-I RNAi knockdown results in a 39% increase in mean lifespan [19302370]. Fruit fly
    14-3-3epsilon CG31196 gene product from transcript CG31196-RA Loss of 14-3-3ε results in increased stress-induced apoptosis, growth repression and extended lifespan of flies, in a foxo-dependent manner. Mean lifespan of males and females is increased by 25% and 49%, respectively. Increased 14-3-3ε expression also reverts foxo-induced growth defects. No effect of lifespan is observed when overexpressing 14-3-3ε in adipose tissue, indicating that endogenous foxo activity in this tissue is low under normal conditions [18665908]. Fruit fly
    GH1 Growth hormone 1 Transgenic mice overexpressing bovine GH1 are bigger than controls and display early onset of pathological changes in the kidneys such glomerulosis and glomerulonephritis as well as signs of premature aging such as a shortened lifespan, increased astrogliosis, shortened reproductive lifepsan and early onset of age-related changes in cognitive function, hypothalamic neurotransmitter turnover, and plasma corticosterone levels [14583653]. Cattle
    frh-1 FRataxin (involved in human Friedrich's ataxia) Homolog Complete absence of frataxin,the mitochondrial protein defective in individuals with Friedreich ataxia is lethal, while its partial deficiency extends animal lifespan in a p53 dependent manner. Frataxin knockdown via RNAi extends mean and maximum lifespan by 19 and 37%, respectively [23247094]. Substantial reduction of frataxin protein expression is required to extend lifespan, affect sensory neurons functionality, remodel lipid metabolism and trigger autophagy. Beclin and p53 genes are required to induce autophagy and concurrently reduce lipid storages and extend animal lifespan in response to frataxin suppression. Frataxin expression modulates autophagy in the absence of p53 [23247094]. Nematode
