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

    XRCC1 X-ray repair complementing defective repair in Chinese hamster cells 1 XRCC1 was found to be associated with longevity [16518718]. Human
    wwp-1 WW domain Protein (E3 ubiquitin ligase) 1 RNA interference of wwp-1 decreases median lifespan by 9% in wild-type animals and 24% in daf-2 mutants [18006689]. Loss of wwp-1 function by RNAi or mutation reduces lifespan at 25 degree Celsius, but not 20 degree Celsius. wwp-1 overexpression extends lifespan by up to 20%. Reduced levels of wwp-1 completely suppress the extended longevity of eat-2 mutants. Lifespan of wwp-1 mutants across entire food concentration range by bacterial dilution in liquid culture or on solid plates does not noticeable change. There is no difference in wwp-1 mRNA levels under AL and DR. RNAi reduction of pha-4, but not of daf-16 suppresses increased longevity by wwp-1 overexpression. Mutations in iron sulphur component of complex III, isp-1, increases longevity by reducing mitochondrial function. wwp-1 RNAi does not suppress the extended lifespan of isp-1 mutants and has only minor suppressive effects on lifespan of another mitochondrial mutant, clk-1, and in cyc-1 RNAi treated worms. RNAi depletion of wwp-1 has no effect on long lifespan of daf-2 mutants [19553937]. Nematode
    WWOX WW domain containing oxidoreductase WWOX was found to be associated with longevity [22279548]. WWOX was found to be associated with longevity [24244950]. Human
    WRKY6 WRKY transcription factor 6 Deletion of the WRKY6 promoter results in defects in root and leaf cell senescence [11722756]. WRKY6 is a transcription factor involved in controlling processes related to senescence and pathogen defence [11722756] and is a positive regulator of PR1 expression [12000796]. WRKY6 is strongly expressed during senescence [11722756].
    Wortmannin Treatment of Drosophila imago with 0.5 micromolar wortmannin increases median (by 5%) and maximum (by 39%) lifespan in males (p < 0.001), but the lifespan differences in females were statistical insignificant (p > 0.05) [22661237]. Low dose of wortmannin (5 microM) slightly increase the median and maximum lifespan [20017609].
    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
    wip-1 Wiskott-Aldrich syndrome protein (WASP)-Interacting Protein and gene assignment RNA interference decreased median lifespan by 33% in daf-2 mutants. Nematode
    WHI3 WHIskey 3 Deletion of WHI3 decreases replicative lifespan by 25% in the a strain [18340043] and decreases chronological lifespan [21447998 ] Budding yeast
    WRN Werner syndrome, RecQ helicase-like Mutation in WRN causes Werner Syndrome which characteristics includes prematurely aged facies, scleroderma-like skin changes, cataracts, arteriosclerosis, subcutaneous calcification, and diabetes mellitus [McKusick et al. 1963; 5327241]. Inheritance is autosomal recessive and malignancy is frequent. THe frequency is 3 per million individuals in Japan [7460386]. Cells from a Werner heterozygote exit the cell cycle at a faster rate than do normal cells [8265666]. Loss of WRN promoter aberrant mitotic recombination [11316787]. The single nucleotide polymorphism rs1800392 in WRN has been associated with exceptional longevity in a plethora of genetic signatures [22279548]. WRN was found to be associated with longevity [10069711; 20855428; 20855428; 20855428 ;17903295; 22406557; 16405962; 16405962; 16405962; 20855428; 20855428; 20855428; 22279548]. WRN was found to be associated with longevity [24244950]. Human

    vit-1 Vitellogenin-1 vit-1 RNAi animals have a mean lifespan that 103.3% of controls, but not significant different. vit-1 is differentially expressed in daf-16 and daf-2 RNAi animals [12845331]. Nematode
    vit-5 VITellogenin structural genes (yolk protein genes) 5 RNA interference against vit-5 extends mean lifespan by 10-22%. vit-5 is differentially transcribed in daf-16 and daf-2 RNAi animals [12845331]. RNAi knockdown of vit-5 starting at hatching or only during the adulthood significantly extends lifespan of wild-type, but does not alter, or even shortens the lifespan of eat-2 mutants [22810224]. Nematode
    vit-2 VITellogenin structural genes (yolk protein genes) vit-2 RNA interference extends mean lifespan by 21-24%. vit-2 is differentially transcribed in daf-16 and daf-2 RNAi animals [12845331]. vit-2 functions in germ-line development by regulating the abundance of native versus oxidized LDL-like lipoproteins [11408580].
