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

    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
    rict-1 RICT0r (Rapamycin-Insensitive Companion of TOR) homolog C. elegans with mutations in the TORC2 complex gene rict-1 (Rictor) grow slowly and have small body size, and live slightly longer than wild-type when maintained on “rich” food such as the RNAi feeding strain HT115 and at elevuated temperature (25 degree Celsius) [Soukas et al., 2009 in (Robida-Stubbs et al., 2012)]. rict-1 RNAi at 20 degree Celsius in the adulthood increases mean, median, 75th %ile and maximum lifespan by 12-42, 22-29, 13-32 and 28-54%, respectively, dependent on skn-1. daf-16 is not required for lifespan to be increased by rict-1 RNAi, or when TORC1 and TORC2 are blocked by ragc-1;rict-1 RNAi. rict-1 RNAi extends mean, median, 75th %ile and maximum lifespan in the intestine-specific RNA stains VPS288 by 18, 19, 18 and 16%, respectively [22560223]. Nematode
    rsks-1 RSK-pSeventy (RSK-p70 kinase) homolog RNA interference reducing S6K (rsks-1) mRNA levels by about two-fold extends mean lifespan 13-47% and maximum lifespan by up to 60%. Deletion mutants also live longer. A life-extending effect was also observed in daf-16 mutants and sir-2.1 mutants but not in daf-2 mutants. TOR RNA interference further extends lifespan of rsks-1 mutants [17266679]. DAF-16 reduces expression of rsks-1 [15253933;22560223]. Autophagy is reduced by knockdown of S6 kinase RSKS-1 [22560223], as it increases translation downstream of TORC1 but also promotes autophagy [15296714]. Nematode
    hcf-1 Host Cell Factor-1 hcf-1 is conserved protein [12826401], ubiquitously expression in C. elegans under normal culture conditions and predominantly nuclear [7876203]. HCF-1 forms a complex with DAF-16. hcf-1 inactivation by mutation cause a daf-16-dependent lifespan extension of up to 40% and heightened resistance to specific stimuli. The hcf-1(ok559) mutation increases mean and maximum lifespan by 10-37 and 29%, while the strong hcf-1(pk924) mutation extends mean and maximum lifespan by 29-31 and 53-88%, respectively. In the absence of hcf-1 there is a greater enrichment of DAF-16 at its target gene promoters and more robust DAF-16-mediated regulation of selective transcriptional targets. hcf-1 mutation extends lifespan of glp-1(e2141) mutants which lack germline cells, [18828672]. SKN-1 contributes to the enhanced oxidative stress resistance incurred by hcf-1 mutation. HCF-1 prevents the nuclear accumulation of SKN-1 and represses the transcriptional activation of SKN-1 specifically at target genes involved in cellular detoxification [22568582]. Nematode
    nac-3 NADC (Na+-coupled dicarboxylate transporter) family RNA interference knockdown of nac-3 leads to an 15% increase in average lifespan. Nematode
