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

    aak-2 AMP-Activated Kinase 2 AAK-2 could be a sensor that couples energy levels and insulin-like signals to lifespan. aak-2(ok524) knockout mutants have a 12% and 18% shorter mean and maximum lifespan, respectively as well as faster age-dependent accumulation of a lipofuscin-like fluorescent pigment in the intestine [15574588]. sDR increases AMP:ATP ratio. aak-2 mutation suppresses lifespan extension and delay of the decline in locomotor activity resulting from sDR. A constitutive active mutation of aak-2 is sufficient to cause increase stress resistance as well as to significantly extend lifespan. Both increased stress resistance and extended lifespan is reverted in daf-16 knockdown by RNAi. sod-3 mRNA is increased by constitutive active form of aak-2 and decreased by aak-2 mutation. The increase in sod-3 mRNA is dependent on expression of DAF-16. Worm and human AMPK phosphorylate DAF-16 (greatly enhanced by presence of AMP) at least in six residues (T166, S202, S314, S321, T463 and S466) [17900900]. aak-2 mutation cancels out the lifespan extension effect of sDR and PD, regardless of the concentration of bacteria or peptones. bDR significantly extends lifespan of aak-2 mutants, but to lesser extent than that of wild-type. eat-2 mutation extends the lifespan of aak-2 mutants to the same extent than that of wild-type. Resveratrol does not increase lifespan of aak-2 mutants [19239417]. daf-2(m577);aak-2(ok524) double mutant has a lifespan that is indistinguishable from those of aak-2(ok524) single mutant. Transgenic animals with a higher aak-2 gene dose live on average 13% longer with a maximum lifespan extension on up to 25% [15574588]. Nematode

    age-1 AGEing alteration 1 Recessive knockout mutants of age-1 have a 40-65% increase in mean lifespan and a 65-110% increase in maximum lifespan [8608934; 8700226]. age-1(mg44) zygotic null mutants have a mean (99%) and maximum (117%) lifespan extension [18828672]. Even in axenic culture lifespan of age-1 is extended up to 100%. age-1 mutation significantly extends lifespan under AL, but only slightly under sDR [16720740]. RNAi against age-1 extends lifespan by 30% [8700226; 8608934]. age-1 RNAi increases mean and maximum lifespan by 36-46% and 48-50% [12447374]. RNAi against age-1 increases mean lifespan by 83% [18828672]. age-1 mutants are dauer constitutive [8056303] and display lower brood size as well as increased embryonic lethality [9504918]. Additionally, age-1 mutants have elevated levels of superoxidase dismutase and catalase activities [8389142]. age-1 RNAi and mutation extend lifespan by 30% and 100%, respectively [8700226; 8608934].

    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-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].
