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

    aph-2 Anterior PHarynx defective aph-2 RNAi in the adulthood extends the lifespan [New longevity regulators]. Nematode
    apr-1 APC Related Nematode
    aps-1 AdaPtin, Small chain (clathrin associated complex) 1 aps-1 RNAi in the adulthood extends mean lifespan by 8% without any apparent effect on maximum lifespan [23144747]. Nematode
    aqp-1 AQuaPorin or aquaglyceroporin related 1 aqp-1 expression changes in response to glucose or glycerol. Similar to daf-16 and hsf-1 mutants, aqp-1 mutants were short-lived, and their short lifespan was not further decreased by glucose. Overexpression of aqp-1::GFP rescues short lifespan of aqp-1 deletion mutants and partially prevented glucose from shortening lifespan. Glucose or glycerol feeding downregulates aqp-1 in wild-type. In daf-16 and/or hsf-1 mutants aqp-1 is repressed and glucose feeding does not significantly affect its expression. aqp-1 mutation does not further decrease the short lifespan of daf-16 and/or hsf-1 mutants. aqp-1 transgene is expressed in pharynx and intestine (which behaves as entire endoderm of animal, including adipose tissues). Dietary glucose does not cause significant differences in levels of glucose or glycerol in wild-type vs. aqp-1 mutants [19883616]. Nematode
    arl-8 ARF-Like 8 RNA interference of arl-8 decreases median lifespan by 35% in a daf-2 background and 9% in daf-2/daf-16 double mutants [18006689]. Nematode
    arx-4 ARp2/3 compleX component 4 RNA interference of arx-4 decreases median lifespan by 61% in a daf-2 background and 51% in daf-2/daf-16 double mutants [18006689]. Nematode
    asb-1 ATP Synthase B homolog asb-1 RNAi in the adulthood extends the mean lifespan by 7% without changing the maximum lifespan [23144747]. Nematode
    asb-2 ATP Synthase B homolog 2 RNA interference of abs-2 leads to lifespan extension [16103914]. Nematode
    asg-1 ATP Synthase G homolog 1 RNA interference of asg-1 leads to lifespan extension [15998808]. Nematode
    asg-2 ATP synthase subunit 2 Knockout mutations in asg-2 result in developmental arrest and increased lifespan [11410594]. Nematode
    Ash-2 RNAi extended fertile lifespan. Nematode
    asm-3 Acid SphingoMyelinase 3 RNA interference of asm-3 increases mean lifespan by 50% [17608836]. Nematode
    asp-3 ASpartyl Protease 3 RNA interference against asp-3 significantly reduces lifespan of eat-2(ad1116) mutants, without any significant affect on the lifespan of wild-type. Mean and 75%ile lifespan of eat-2 mutants is reduced by 13-14% and 5-9% by asp-3 RNAi. ASP-3 is upregulated in eat-2 mutants [22810224]. Nematode
    atg-7 AuTophaGy (yeast Atg homolog) 7 RNA interference against atg-7 shortens mean lifespan by 23% and maximum lifespan by 30% in a eat-2 mutant background but not in wild-type animals. Thus, atg7 RNAi does not affect lifespan of wild-type, but totally cancels out the lifespan extension effect of eat-2 mutation [17912023]. Nematode
    atp-2 ATP synthase F1 subunit gamma 2 RNA interference of atp-2 results in extended lifespan [12471266]. atp-2 RNAi significantly extends mean lifespan by 14% [11410594]. 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
    atp-4 ATP synthase subunit 4 RNA interference of atp-4 results in lifespan extension [16103914]. Nematode
    atp-5 ATP synthase subunit 5 RNA interference of atp-5 results extended lifespan [16103914]. Nematode
    B0035.12 RNAi of B0035.12 increases mean and maximum lifespan by 12 and 20%, respectively [19293945]. Nematode
    B0280.9 Nuclear Hormone Receptor family B0280.9 RNAi in the adulthood extends the lifespan [New longevity regulators]. Nematode
    B0393.6 F-box A protein B0393.6 RNAi in the adulthood extends the lifespan [New longevity regulators]. Nematode
    B0491.5 RNA interference of B0491.5 in adulthood results in a 16% increase in mean lifespan [17521386]. Nematode
    B0511.6 RNA interference of B0511.6 in adulthood extended mean lifespan by 50% [17411345]. Nematode
    B0546.3 RNA interference of B0546.3 increases mean lifespan by 27% [17608836]. Nematode
    baf-1 Barrier to Autointegration Factor 1 RNA interference of baf-1 decreases median lifespan by 28% in daf-2 mutants [18006689]. Nematode
    Factors are an extension of GenAge and GenDR.
