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

    let-60 LEThal The let-60(n1046gf) activating mutation greatly reduces lifespan of wild-type, weakly suppresses constitutive dauer diapause in daf-2 and age-1 mutants and extends lifespan induced by mutation of daf-2 [16164423]. Nematode
    nlp-7 Neuropeptide-Like Protein nlp-7 RNAi or overexpression reduces oxidative stress resistance and shortens lifespan of wild-type under AL. nlp-7 RNAi significantly reduces extended lifespan of eat-2 mutants, but failed to block lifespan extension of age-1 or clk-1 mutants. Lifespan of nlp-7 mutants increases only moderately by sDR [19783783]. nlp-7 expression is induced under DR via the use of a chemically defined axenic medium [17023606] and by sDR [19783783]. Nematode
    cup-4 Coelomocyte UPtake defective 4 cup-4 RNAi or overexpession reduces oxidative stress resistance and shortens lifespan of wild-type under AL. cup-4 RNAi significantly reduces the extended lifespan of eat-2 mutants, but failed to block lifespan extension of age-1 or clk-1 mutants. Lifespan of cup-4 mutants increases only moderately by sDR [19783783]. Nematode
    tdp-1 TAR DNA-binding Protein homolog 1 tdp-1(ok803) mutation increases mean and maximum lifespan at 20 degree Celsius but not at 25 degree Celsius. tdp-1(ok803) reduce the lifespan of daf-2(e1370) mutants, but does not does not reduces the lifespan of daf-16(mu86) mutants. RNAi against tdp-1 reduces lifepsna of daf-2(e1370) mutants. tdp-1 overexpression strains have a reduced lifespan at 20 and 25 degree Celsius [Vaccaro et al. 2012]. Nematode
    prx-13 PeRoXisome assembly factor Knockdown of prx-13 increases mean and maximum lifespan by 17% (28%!) and 11% respectively. prx-13 knockdown from hatching does no effect [22509016]. Nematode
    prx-11 PeRoXisome assembly factor RNAi against prx-11 increases mean and maximum lifespan 11% [22509016]. Nematode
    prx-5 PeRoXisome assembly factor Postdevelopmental RNAi kockdown of prx-5 in the enhanced RNAi strain eri-1(mg366) increases mean lifespan by 30% [17411345]. Knockdown of prx-5 initiated on the first day of adulthood increases mean and maximum lifespan by 8% (6%!) and 11% respectively. prx-5 knockdown from hatching has no effect on lifespan or slightly shortened lifespan [22509016]. This might indicate that prx-5 is important during development but may exert postedevelopmental detrimental effects on longevity [22509016]. Nematode
    F18F11.1 F18F11.1 knockdown extends mean lifespan by 17% and 11%, respectively [22509016]. Nematode
    bub-3 yeast BUB homolog RNAi against bub-3 increases mean and maximum lifespan by 6-7% and 7%, respectively [18059442]. Nematode
    fzy-1 FiZzY (CDC20 protein family) homolog RNAi against fzy-1 increases mean and maximum lifespan by 17-32% and 14%, respectively [18059442]. Nematode
    R03D7.4 RNAi against R03D7.4 increases mean and maximum lifespan by 9-17% and 7%, respectively [18059442]. Nematode
    ncbp-2 Nuclear Cap-Binding Protein RNAi against ncbp-2 decreases mean and maximum lifespan by 23-25% and 7%, respectively [18059442]. Nematode
    mrpl-47 Mitochondrial Ribosomal Protein, Large RNAi against mrpl-47 extends mean and maximum lifespan by 18% and 50%, respectively [12447374]. This lifespan extension is not suppressed by daf-16 mutation (mgDF74). mrpl-47 knockdown results in lower ATP content and oxygen consumption [12447374]. Nematode
    F13G3.7 RNAi against F13G3.7 increases mean and maximum lifespan by 25% and 50%, respectively. Lifespan extension by F13G3.7 RNAi is dependent on daf-16 [12447374]. Nematode
    wah-1 Worm AIF (apoptosis inducing factor) Homolog wah-1 RNAi in the adulthood extends the lifespan [New longevity regulators]. RNAi against wah-1 started after the animal reaches the late L4 stage extends mean lifespan by 7-8% [22103665]. Nematode
    ucr-1 Ubiquinol-Cytochrome c oxidoReductase complex RNAi against ucr-1 increases mean lifespan by 20% [17608836]. ucr-1 RNAi started after the animal reached the late L4 stage increase mean lifespan by 8-14% [22103665]. Nematode
    F09F7.4 NEK (NEver in mitosis Kinase) Like F09F7.4 RNAi in the adulthood extends the lifespan [New longevity regulators]. RNAi against F09F7.4 started after the animal reached the late L4 stage increases mean lifespan by 6-12% [22103665]. Nematode
    rrt-1 aRginyl aa-tRNA syntheTase rrt-1 RNAi in the adulthood extends the lifespan [New longevity regulators]. Kockdown of rrt-1 via RNAi started after the animal reached the late L4 stage increases lifespan by 15-27% [22103665]. Nematode
    eft-2 Elongation FacTor Post-developmental RNA interference reduces mean lifespan by 15% [17673661]. Knockdown of eft-2 started after the animal reached the late L4 stage increases mean lifespan by 6-27% and 8%, respectively [22103665]. Nematode
    mdh-1 Malate DeHydrogenase RNAi against mdh-1 decreases median lifespan by 10% in wild type animals and by 16% in daf-2 mutants [18006689]. mdh-1 RNAi started after the animal reached the late L4 stage increases mean and maximum lifespan by 4-27% and 9% [22103665]. Nematode
    daf-8 abnormal DAuer Formation daf-8 mutation in adults increases mean lifespan by 9-31% but it did not increase maximum lifespan [17900898]. Nematode
    daf-14 abnormal DAuer Formation daf-14(m77) mutation increases mean lifespan by 21-44% and maximum lifespan by 29% [17900898]. Nematode
    daf-7 abnormal DAuer Formation daf-7 mutation does not significantly change lifespan [8247153]. Mutations in daf-7 cause up to 50% mean and maximum life-extension. This effect is dependent upon daf-3 and on daf-16 but independent of daf-2. daf-7(e1372) increases mean and maximum lifespan by 13-39% and 55%, respectively. daf-7(m62) increases mean and maximum lifespan by 20-29% and 29% [17900898]. RNAi against daf-7 only in the adulthood increases mean and maximum lifespan by 26 and 7%, respectively [17900898]. Nematode
    ragc-1 RAs-related GTP binding protein C homolog ragc-1 RNAi only during adulthood increases mean, median and maximum lifespan by 13-33, 21 and 33-37% respectively, but failed so in skn-1 or daf-16 mutant (with and without FUdR). Interference with TORC1 by ragc-1 RNAi increases heat resistance in daf-16 and skn-1 mutants, but not not in skn-1;daf-16 double mutant. ragc-1 RNAi increases lifespan in a strain in which RNAi is restricted to the intestine (VP288). RNAi of ragc-1 decreases overall mRNA translation but increases autophagy (measured by LGG-1 puncta) [22560223]. Nematode
    raga-1 RAs-related GTP-binding protein A raga-1 RNAi only during adulthood increases mean, median, 75th %ile and maximum lifespan by 9-42, 26-28, 16-52 and 35%, respectively, but failed so in skn-1 or daf-16 mutant (with and without FUdR). Lifespan of the skn-1;daf-16 mutant was unaffected by raga-1 RNAi. Knockdown of raga-1 dramatically increases stress tolerance in an skn-1 but not daf-16-dependent manner [22560223]. Nematode
