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

    mpk-1 MAP Kinase RNAi against F43C1.2B (encoding mpk-1) decreases mean and maximum lifespan by 8-14% and 14%, respectively [18059442]. Nematode
    tbp-1 TATA-Binding Protein RNAi against tbp-1 decreases mean and maximum lifespan by 15-27% and 21%, respectively [18059442]. Nematode
    Y47D3A RNAi against Y47D3A.29 decreases mean and maximum lifespan by 19-26% and 34% [18059442]. Nematode
    atp-3 ATP synthase subunit RNA interference against atp-3 results in lifespan extension [16103914]. atp-3 RNAi increases lifespan by 46% (mean by 33 and maximum by 70%). RNAi of atp-3 during larval stage is necessary and sufficient for lifespan prologation, while atp-3 RNAi only during the adulthood fails the extend lifespan. atp-3 RNAi results in reduced pharageal pumping, defection and motility as well as ATP levels and body size [12471266]. Nematode
    pas-1 RNAi against pas-1 started after the animal reached the late L4 stage decreases mean lifespan by 18-19% [22103665]. RNAi pas-1 decreases lifespan of daf-2 mutant, but not of WT or glp-1 mutant [17392428]. Nematode
    gdi-1 GDI (RabGDP Dissociation Inhibitor) family RNAi against gdi-1 started after the animal reaches the late L4 stage decreases mean lifespan by 6-7% [22103665]. gdi-1 RNAi decrease median lifespan by 34% in daf-2 mutants [18006689]. 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
    bra-1 BMP receptor Associated protein family bra-1(nk1) mutation reduces mean lifespan by 6-25% [17900898]. Nematode
    daf-5 abnormal DAuer Formation daf-5(e1386) mutation reduces mean lifespan by 19% and maximum lifespan by 21% [17900898]. Nematode
    bar-1 beta-catenin BAR-1 may play a role in regulating daf-16 during dauer formation, particularly in conditions of oxidative stress as it directly interaction with DAF-16 and loss of bar-1 reduces activity of DAF-16 in dauer formation and lifespan. Deletion of bar-1 reduces mean (44%) and maximal (18%) lifespan, which is to a similar degree as seen to daf-16 mutants [15905404]. SMK-1 is important DAF-16 modulation of lifespan and specific stress response [5]. Nematode
    phb-1 mitochondrial ProHiBitin complex 1 phb-1 RNAi shortens lifespan of wild-type, aak-2, cep-1 (p53) and jnk-1 mutants, but increases lifespan of daf-2, daf-7, daf-4, daf-11, gas-1, mev-1, isp-1, clk-1, nhr-49, fat-7 and gld-1 mutants. daf-16 mutation fully suppressed the exceptional long-lifespan of prohibitin-depleted (via RNAi) daf-2 mutants [19812672]. Nematode
    phb-2 mitochondrial ProHiBitin complex 2 phb-2 RNAi shortens lifespan of wild type, aak-2, cep-1 (p53) and jnk-1 mutants, but increases lifespan of daf-2, daf-7, daf-4, daf-11, gas-1, mev-1, isp-1, clk-1, nhr-49, fat-7, gld-1 mutants. daf-16 mutation fully suppressed exceptionally long-lifespan of via RNAi prohibitin-depleted, daf-2 mutants [19812672]. Nematode
    daf-3 abnormal DAuer Formation daf-3(mgDf90) mutation decreases mean lifespan by 0-16% and maximum lifespan by up to 9-21%. daf-3(mgDf90) decreases mean lifespan even by 19% [17900898]. Mutation of daf-3 results in a wild-type lifespan, but greatly extends the lifespan of the long-lived daf-9 mutant [11782415]. daf-3 mutations are dauer defective. Nematode
    glp-1 abnormal Germ Line Proliferation glp-1(qu158) mutations result in defects in germ-line proliferation and extension of lifespan by about 30%, which requires daf-16 [11799246]. glp-1(bn18) mutation increases mean, median, 75th %ile and maximum lifespan by 27-37, 26-33, 24-29 and 35%, respectively [22560223]. glp-1(e2141) mutation increases mean (32%) and maximum (53%) lifespan [18828672]. Two alleles of glp-1 that cause overproliferation of gemrline cells, glp-1(oz112gf) and glp-1(q485), result in a shortened lifespan [11799246]. In glp-1 mutants, Z2 and Z3 generate only a few germ cells, which enter meiosis and differentiate as sperm [3677168]. Nematode
    mev-1 Abnormal MEthyl Viologen sensitivity Loss of function in mev-1 shortens lifespan to 66% of wild-type (i.e. by 34%) and accelerates accumulation of aging-associated biomarkers such as protein carboynls and fluorescent materials. mev-1 mutants are hypersensitive to raised oxygen concentrations and their lifespan decreases dramatically as oxygen concentrations increase [9716135]. Mutation of mev-1 results in paraquat sensitivity, slow grows, and low fecundity. mev-1 mutants have a 50% reduction in superoxide dismutase activt relatively to wild-type [2233820]. Nematode
    nhr-49 Nuclear Hormone Receptor family RNA interference of nhr-49 shortens lifespan by 30-40% and alters fatty acid composition. A mutant allele, nhr(nr2041) results in an even shorter lifespan. nhr-49 mutant animals accumulate fat, due to decreased expression of enzymes involved in fatty acid beta-oxidation [15719061]. Nematode
    pnk-1 PaNtothenate Kinase RNA interference of pnk-1 shortens lifespan in both wild-type and daf-2 mutant animals. pnk-1 transcription is elevated in daf-2 mutants in a daf-16-dependent manner [12690206]. Nematode
    unc-10 UNCoordinated Mutation in unc-10 reduces maximum lifespan 35% [17592521]. Nematode
    W09C5.8 RNAi against W09C5.8 increases mean and maximum lifespan by 62% and 50%, respectively [12447374]. Lifespan extension by RNAi of W09C5.8 is not suppressed by daf-16. Loss of W09C5.8 activity via RNAi can also result in a shortened lifespan, reduced fertility and defects in mitochondrial respiratory chain function [19074434]. W09C5.8 RNAi animals have lower ATP content and oxygen consumption [12447374]. Nematode
    lys-1 LYSozyme lys-1 RNAi in the adulthood extends the lifespan [New longevity regulators]. Overexpression of lys-1 increases mean and maximum lifespan by 5 and 26%, but has no significant effect on median lifespan [22737090]. Nematode
    ztf-12 Zinc finger Transcription Factor family RNA interference of ztf-12 results in a shortened lifespan. ztf-12 is a target of daf-16 [16380712]. Nematode
    lin-40 abnormal cell LINeage 40 RNA interference decreases median lifespan by 24% in wild-type animals, 38% in a daf-2 background and 24% in daf-2/daf-16 double mutants [18006689]. Nematode
    aakb-1 AMP-Activated Kinase Beta subunit 1 RNA interference of aakb-1 results in decreased lifespan and earlier accumulation of lipofuscin [16673436]. Nematode
