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

    dcp-66 Deacetylase Complex Protein 66 dcp-66 RNAi shortens the mean lifespan by 29% and suppresses lifespan extension by isp-1 mutation, but does not significantly affect lifespan extension neither by eat-2 nor daf-2 mutation [22829775]. Nematode
    tps-2 Trehalose 6-Phosphate Synthase 2 RNA interference mediated inactivation of the trehalose-biosynthetic gene trehalose-6-phosphate synthase-2 (tps-2) decreases daf-2 mutant's long lifespan [20477758]. Nematode
    tps-1 Trehalose 6-Phosphate Synthase 1 RNA interference mediated inactivation of the trehalose-biosynthetic gene trehalose-6-phosphate synthase-1 (tps-1) decreases daf-2 mutant's long lifespan [20477758]. Nematode
    let-4 LEThal 4 let-4 (alias sym-5) is downregulated in space. RNA intereference of let-4 extends mean and 75%ile lifespan by 4%, but reduces maximum lifespan by 25% [22768380]. Nematode
    unc-51 UNCoordinated-51 unc-51(e369) mutation reduces mean but extends maximum lifespan. unc-51(e369) mutation reduces lifespan of eat-2(ad1116) mutants to that of wild-type [18219227]. Nematode
    NAC N-acetyl cysteine Treatment with 10 mM of NAC has no effect on the lifespan of wild-type, but fully abolishes the increased longevity of nuo-6 and severly limits that of isp-1. At high concentration (> 10-15 nM) NAC can be become deleteroius even on the wild-type [21151885]. Nematode
    Vitamin C Treatment with 1 mM vitamin C has no effect on lifespan of wild-type, but significantly shortens the lifespan of both isp-1 and muo-6 mutants [21151885]. Supplementation with vitamin C normalizes the median lifespan of wnr-1 and mir-124 mutants, which both exhibit premature aging [23075628]. Nematode
    Y59A8B.2 RNA interference decreased median lifespan by 59% in daf-2 mutants. Nematode
    Y46G5A.6 phi-3 RNA interference of Y46G5A.6 in adulthood shortens the extends lifespan of daf-2(mu150) mutants. Only a negligible or small reduction in the lifespan of wild-type worms occurs by knockdown of Y46G5A.6 [17392428]. Nematode
    sbds-1 Shwachman-Bodian-Diamond Syndrome protein homolog 1 RNA interference of sbds-1 decreases median lifespan by 24% in daf-2 mutants [18006689]. RNAi knockdown of sbds-1 starting at hatching or only during the adulthood significantly decreases lifespan of eat-2 without affecting wild-type lifespan. SBDS-1 are elevated in eat-2 mutants. Increased content of SBDS-1 is, at least partially, required for lifespan-extension by DR [22810224]. Nematode
    kri-1 human KRIT 1 (Krev interaction trapped/cerebral cavernous malformation 1) homolog RNA interference suppresses glp-1 life-extension but does not shorten lifespan of wildtype strains. kri-1(ok1251) mutation does not shorten the lifespan significantly [22560223]. Nematode
    daf-12 Abnormal DAuer Formation Mutations in daf-2 and daf-12, but not mutations in daf-12 alone, nearly quadruples lifespan [7789761]. Recessive loss of function mutation in daf-12 shortens lifespan. daf-12 activity is required for lifespan extension after germ line ablation [10360574]. daf-12 mutation suppresses the lifespan extension by mutation in daf-28 [8807293]. daf-12 mutants are dauer defective and heterochronic [7219552]. Some daf-12 alleles exhibit synthetic lethality with mutation of age-1 [8807293] or daf-12 [1732156]. Nematode
    cul-1 CULlin 1 RNAi of cul-1 decreases lifespan of daf-2 mutant, but not of wild-type or glp-1 mutant. The CUL-1 complex functions in postmitotic, adult somatic tissues of insulin/insulin-like growth factor-1-signaling mutants to enhance longevity. It may act, at least in part, by promoting the transcriptional activity of DAF-16/FOXO [17392428]. Nematode
    cku-70 Caenorhabditis KU 70 RNA interference of cku-70 further increases the lifespan of daf-2 mutants. Lifespan of daf-16 mutants is slightly decreased by cku-70 RNAi [16099946]. Nematode
    cit-1.2 CyclIn T 1.2 RNA interference cit-1.2 decreases median lifespan by 27% in daf-2 mutants [18006689]. Nematode
    tbc-7 TBC (Tre-2/Bub2/Cdc16) domain family RNA interference of tbc-7 decreased median lifespan by 28% in daf-2 mutants [18006689]. Nematode
    C29F9.1 RNA interference of C29F9.1 decreases median lifespan by 35% in daf-2 mutants [18006689]. Nematode
    mdt-26 MeDiaTor 26 RNA interference of mdt-26 decreases the median lifespan 42% in daf-2 long-lived mutants [18006689]. Nematode
    baf-1 Barrier to Autointegration Factor 1 RNA interference of baf-1 decreases median lifespan by 28% in daf-2 mutants [18006689]. Nematode
