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

    VPS27 Under starvation conditions VPS27 deletion mutants have a dramatically reduced lifespan [20953148]. Budding yeast
    Foxo3 House mouse
    Y59A8B.2 RNA interference decreased median lifespan by 59% in daf-2 mutants. Nematode
    VPS25 Under starvation conditions VPS25 deletion mutations have dramatically reduced lifespan [20953148]. Budding yeast
    YMR226C Replicative lifespan of TMA29 mutants increases by 35% in the alpha strain and decreases by 10% in the a strain [18340043]. Budding yeast
    YDR124W Deletion of YDR124W increases replicative lifespan by 30% in the alpha and decreases lifespan by 10% in a strain [19030232]. Budding yeast
    C29F9.1 RNA interference of C29F9.1 decreases median lifespan by 35% in daf-2 mutants [18006689]. Nematode
    Vitamin C Treatment with 1 mM vitamin C has no effect on lifespan of wild-type, but significantly shortens the lifespan of both isp-1 and muo-6 mutants [21151885]. Supplementation with vitamin C normalizes the median lifespan of wnr-1 and mir-124 mutants, which both exhibit premature aging [23075628]. Nematode
    mir-34 mir-34 loss triggers a gene expression profile of accelerated brain aging, late-onset brain degeneration and catastrophic decline in survival, while mir-34 upregulation extends median lifespan and mitigated neurodegeneration induced by polyglutamine. Fruit fly
    daf-12 Abnormal DAuer Formation Mutations in daf-2 and daf-12, but not mutations in daf-12 alone, nearly quadruples lifespan [7789761]. Recessive loss of function mutation in daf-12 shortens lifespan. daf-12 activity is required for lifespan extension after germ line ablation [10360574]. daf-12 mutation suppresses the lifespan extension by mutation in daf-28 [8807293]. daf-12 mutants are dauer defective and heterochronic [7219552]. Some daf-12 alleles exhibit synthetic lethality with mutation of age-1 [8807293] or daf-12 [1732156]. Nematode
    ABP1 Actin Binding Protein 1 ABP1 deletion increases replicative lifespan by 30% in the alpha strain and decreases replicative lifespan by 20% in the a strain [18340043]. Deletion of ABP1 increases replicative lifespan by 20% in the alpha strain and decreases replicative lifespan by 20% in the a strain [19030232]. Budding yeast
    ACB1 Acyl-CoA-Binding 1 ACB1 deletion extends chronological lifespan under starvation/extreme DR. Similar heat-shock resistance and resistance to a very hight concentration of acetic acid (but not resistance to oxidative stress) was enhanced by the deletion of ACB1. Deletion of ACB1 in W303-1A and DBY746 genetic backgrounds on synthetic complete media causes severe growth defects and sightly shorter lifespan and also heat-sensitivity [20657825]. Budding yeast
    arf-3 ADP-Ribosylation Factor related 3 RNA interference of arf-3 does not affect lifespan of wild-type but suppresses lifespan extension by isp-1 mutation [22829775].
    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
    Arntl aryl hydrocarbon receptor nuclear translocator-like Arntl knockout mice display symptoms of premature aging including a shorter lifespan, sarcopenia, cataracts, less subcutaneous fat, and organ shrinkage [16847346]. House mouse
    Atm Ataxia telangiectasia mutated homolog (human) Atm-deficient mice are viable, retarded in growth, infertile (male produce no mature sperm and female no gametes), display neurological dysfunction, and exhibit severe defects in T cell maturation while going on to develop thymomas [8917548; 8689683]. The majority of mutant mice rapidly develop thymic lymphomas and die before 4 months of age [8843194]. Cells of Atm(-/-) mice exhibit slow growth also in culture and premature senescence, telomeres are extensively shortened in multiple tissues [8689683]. Mice mutant for Atm and Terc display progressive multi-organ system compromise and features of accelerated aging [12540856]. House mouse
    baf-1 Barrier to Autointegration Factor 1 RNA interference of baf-1 decreases median lifespan by 28% in daf-2 mutants [18006689]. Nematode
    bax Bcl2-associated X protein Inactivation of proapoptotic Bax extends fertile potential and minimized age-related health problems, including bone and muscle loss, excess fat deposition, alopecia, cataracts, deafness, increased anxiety, and selective attention deficit. Bax deficiency does not lead to an increase in tumor incidence. Despite the apparently increased quality of life of aging females lacing Bax, there is no significant differences in overall lifespan [17360389]. House mouse
    BUB1B budding uninhibited by benzimidazoles 1 homolog beta (yeast) Mutations in BUB1B are associated with mosaic variegated aneuplody, a rare human syndrome characterized by aneuplodization, tumour predisposition and several progeroid traits, including short lifespan, growth and mental retardation, cataracts and facial dysmorphisms [16411201; 15475955; 20651707]. Human
    Bub3 budding uninhibited by benzimidazoles 3 homolog (S. cerevisiae) Haploinsufficiency of Bub3 and Rae1, but not haploinsufficiency of either gene by itself, reduces lifespan by 12% and appears to accelerate aging [16476774]. House mouse
    cku-70 Caenorhabditis KU 70 RNA interference of cku-70 further increases the lifespan of daf-2 mutants. Lifespan of daf-16 mutants is slightly decreased by cku-70 RNAi [16099946]. Nematode
    CTA1 CaTalase A 1 CTA1 overexpression partially suppresses the shortened chronological lifespan by ISC1 mutation [21707788]. Budding yeast
    CCL11 chemokine (C-C motif) ligand 11 CCL11 is an age-related systemic factor associated with decreased neurogenesis. Relative levels of CCL11 increase in the plasma during aging an in young mice during Heterochronic Parabiosis [21886162]. House mouse
    CCL11 chemokine (C-C motif) ligand 11 CCL11 exhibits an age-related increase in the plasma and cerebrospinal fluid from healthy human individuals between 20 and 90 years [21886162]. Human
    CCL2 chemokine (C-C motif) ligand 2 CCL2 levels are evaluated in old unpaired and young heterochronic (with old animals) paired mice [21886162]. House mouse
