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

    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
    VWA5A von Willebrand factor A domain containing 5A VWA5A was found to be associated with longevity [21782286]. Human
    VPS36 Vacuolar Protein Sortin 36 VPS36 deletion mutants have a chronological lifespan as long as wild type BY4741. Thus, Vps36 is not necessary for the starvation/extreme DR-dependent lifespan extension [20657825]. Budding yeast
    VPS30 Vacuolar Protein Sorting 30 VPS30 deletion prevents chronological lifespan extension induced by amino-acid DR [20421943]. Budding yeast
    VPS20 Vacuolar Protein Sorting 20 VPS20 deletion decreases mean and maximum replicative lifespan by 16% and 19%, respectively, and additionally cancels out the DR-induced replicative lifespan extension [22912585]. Budding yeast
    VPS13D vacuolar protein sorting 13 homolog D (S. cerevisiae) VPS13D was found to be associated with longevity [22279548]. Human
    vps-34 related to yeast Vacuolar Protein Sorting factor 34 vps-34 RNAi does not significantly change lifespan of wild-type, but cancels out the lifespan extension effect of eat-2 mutation [18282106]. Nematode
    VMA2 Vacuolar Membrane Atpase 2 VMA2 deletion mutants have a reduced ΔΨ and mitochondrial morphology similar to aged cells. The restoration of the vacuolar acidity in daughter cells requires V-ATPase activity as it is eliminated in VMA2 deletion mutant cells [23172144]. VMA2 deletion mutation decreases the mean replicative lifespan by 80% in the alpha strain [18340043]. Deletion of VMA2 decreases mean, median and maximum replicative lifespan by 84%, 84% and 70%, respectively. DR (0.5% glucose restriction) does not extend the replicative lifespan of VMA2 and shortens it even more [23172144]. Budding yeast
    Vitamin D receptor vitamin D (1,25- dihydroxyvitamin D3) receptor Vitamin D receptor was not found to be associated with longevity [21051524]. Human
    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]. Nematode
    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
    vig-1 VIG (Drosophila Vasa Intronic Gene) ortholog vig-1 RNAi in the adulthood extends the lifespan [New longevity regulators]. Nematode
    VEGFA vascular endothelial growth factor A VEGFA was found to be associated with longevity [17574707]. VEGFA was not found to be associated with longevity [17574707]. Human
    Vegf Vascular endothelial growth factor A Vegf exhibits rhythmic expression in the liver [17360649]. Vegf expression is affected by the circadian organization of molecular clockwork. Levels of Vegf mRNA fluctuate in a circadian fashion. Period2 and Cryptochrome inhibit the Vegf promoter [14612524]. House mouse
    VDR vitamin D (1,25- dihydroxyvitamin D3) receptor VDR was found to be associated with longevity [21051524]. VDR was not found to be associated with longevity [20407924]. VDR was found to be associated with longevity [20407924]. Human
    VASH1 vasohibin 1 VASH1 was found to be associated with longevity [22279548]. Human
    VAM7 VAcuolar Morphogenesis 7 VAM7 deletion decreases replicative lifespan under AL and blocked DR-mediated lifespan extension. Replicative lifespan decreases by 70% on DR in VAM7 deletion mutant [18690010]. Budding yeast

    utx-1 human UTX (Ubiquitously transcribed TPR on X) homolog utx-1 RNAi extended mean lifespan by 30%, dependent on DAF-16 activity and not additive in daf-2 mutants [21803287]. utx-1 heterogous knockout also extended lifespan. Nematode

    gpa-1 G Protein, Alpha subunit Up to 10% maximum lifespan extension in gpa-1 knockouts and a 10% decrease when gpa-1 is overexpressed. Loss-of-function of gpa-1 did not extend the lifespan of daf-2 mutants. Nematode
    gpc-1 G Protein, Gamma subunit Up to 10% increase in mean lifespan in knockouts, dependent on daf-16. Nematode
    ARO7 AROmatic amino acid requiring 7 Under starvation/extreme DR deletion of ARO7 increases mean chronological lifespan and confers higher resistance to heat-shock, but made cell more sensitive to acetic acid and leads to growth defects. In W303-1A background ARO7 deletion causes an even more severe growth defect and mutants are short-lived [20657825]. Budding yeast
    Factors are an extension of GenAge and GenDR.
