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

    git3 git3 encodes a G protein-coupled receptor for glucose. git3 deletion increases chronological lifespan in conditions where glucose consumption is not affected. Constitutive activation of the G-alpha subunit acting downstream of Git3 accelerates aging and inhibits the effect of DR. The anti-aging effect of DR and git3 deletion mutation is accompanied by increased respiration and lower ROS production [19266076]. Fission yeast
    gpa2 Guanine nucleotide-binding protein alpha-2 subunit gpa2 (alias git8) encodes the alpha subunit of a heterotrimeric G protein, which acts downstream of Git3. Git8 activity accelerates aging and inhibits the lifespan-extending effect of DR. Constitutive active mutation of gpa2 decreases chronological lifespan under AL (2% glucose) and almost completely cancels out the lifespan extending effect of DR (0.2% glucose) [19266076]. Fission yeast
    sty1 Deleting sty1 cancels out chronological lifespan extension and enhanced heat stress resistance by DR. Sty1 (phosphorylated) and Sty1-dependent gene transcription (atf1, gpx1, cta1, fbp1) is activated during DR in the stationary phase, but are barely activated in glucose rich medium [20075862]. Fission yeast
    atf1 activating transcription factor 1 Activation of transcription factor Atf1 by Sty1 is required for chronological lifespan extension and enhanced heat stress resistance by DR. Deleting atf1 cancels out DR-mediated chronological lifespan extension and enhanced heat stress resistance. Overexpressing atf1 is not sufficient to promote chronological lifespan extension in cells lacking sty1 [20075862]. Fission yeast
    wis1 Constitutive active mutation of wis1 extends chronological lifespan and there is no further beneficial effect of DR [20075862]. Fission yeast
    sck2 serine/threonine protein kinase Sck2 Deletion of sck3 increases maximum chronological lifespan by 200%. Deletion mutant accumulated less reactive oxygen species and had delayed initiation of apoptosis. Additional deletion of pka1 further extend the lifespan of sck3 mutants [16822282]. Fission yeast
    pka1 cAMP-dependent protein kinase 1 pka1 knockouts exhibits a three-fold increase in chronological lifespan with up to 187% longer maximum lifespan [16822282]. Deleting ser/thr cAMP-activated protein kinase pka1 extends chronological lifespan under normal condition, but there is no additive effect with DR [20075862]. Fission yeast
