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

    14-3-3epsilon CG31196 gene product from transcript CG31196-RA Loss of 14-3-3ε results in increased stress-induced apoptosis, growth repression and extended lifespan of flies, in a foxo-dependent manner. Mean lifespan of males and females is increased by 25% and 49%, respectively. Increased 14-3-3ε expression also reverts foxo-induced growth defects. No effect of lifespan is observed when overexpressing 14-3-3ε in adipose tissue, indicating that endogenous foxo activity in this tissue is low under normal conditions [18665908]. Fruit fly
    Akt1 CG4006 gene product from transcript CG4006-RA RNA interference of Akt1 in intestinal stem cells, results in impaired regeneration of the intestinal epithelium and a short lifespan. In males and females on mean lifespan is 11.4% and 7.4% lower [20976250]. Fruit fly
    alpha-Man-I alpha Mannosidase I alpha-Man-I mutant fly exhibit enhanced resistance to paraquat and starvation an a 60% increase in mean lifespan for both sexes. After outcrossing, the mutant exhibit, under normal conditions, an increase in mean lifespan of 22% for females and 38% for males. Maximum lifespan is increased by 15%. alpha-Man-I RNAi knockdown results in a 39% increase in mean lifespan [19302370]. Fruit fly
    Atg2 Autophagy-specific gene 2 Atg2 overexpression increases average female lifespan by 28% [18059160]. Fruit fly
    Aut1 Aut1 depletion form the first day of imaginal stage shortens lifespan by 28% on average in Drosophila and causes morphological behavioural features of premature aging [18219227]. Fruit fly
    bam bag of marbles Bam mutants have an extended lifespan due to germ cell loss. Lifespan of females is on average up to 50% higher and that of males on average s up to 27.8% higher [18434551]. Fruit fly
    CG17856 RNAi of CG17856 results in an increase in mean lifespan of 13-18% in females. In the case of males and post-developmental experiments the results are variable [19747824]. Fruit fly
    CG18809 RNAi of CG18809 results in a 7-19% increase in mean lifespan of females, while neural RNAi results in an increased mean lifespan of up to 12% in females. For males the results are variable [19747824]. Fruit fly
    CG3776 Both overexpression and underexpression of CG3776 (alias Jhebp29) reduces the mean lifespan, where the reduction in males is slightly higher. The lifespan of male flies with under- and overexpressed CG3776 is reduced by 38.8 and 42.6%, respectively when compared with Oregon R flies.The lifespan of female flies with under- and overexpressed CG3776 is reduced by 31.6 and 35%, respectively when compared to Oregon R flies. Among the males and females, relatively to Oregon R and EP835/CyO, the age-specific survival of EP835/EP835 and EP835/Gal4 is reduced in both log-rank and Wilcoxon tests (P < 0.001); survival of EP835/EP835 and EP835/Gal4 differed using the log-rank-test (male: P<0.001; female: P=0.027) [18275960]. Fruit fly
    CG5389 RNAi of complex V subunit CG5389 results in increased mean longevity under standard laboratory food conditions (3% yeast) in males. RNAi started from the development results in a mild lifespan increase in both sexes (3-11% in females and 3-8% in males). Post-developmental RNAi and silencing limited to neurons has variable effects with reduction in lifespan of up to 9% [19747824]. Under rich media conditions CG5389 knockdown throughout development and adulthood increases mean lifespan by 26% and abolished the lifespan extension by DR (started in the adulthood) in males. Suppression of CG5389 only during the adulthood either via RNAi by tub-GS or via oligomycin (a specific inhibitor of complex V) feeding prevents an increase in longevity under DR (started in the adulthood) in males [19968629]. Fruit fly
    CG9172 RNAi against CG9172 increases mean lifespan in females by up to 4-12% when applied in both development and adulthood, and up to 46% when applied in adult neurons only. For males the effect is variable [19747824]. Fruit fly
    CLU clusterin Overexpression of the secretory form of human Clusterin in fruit flies increases mean lifespan. hClu overexpression flies also have greater tolerance to heat shock, wet starvation, and oxidative stress and the whole body amounts of reactive oxygen species is lower [22465014].CLU was found to be associated with longevity [16804001]. Fruit fly
    DNApol-gamma35 DNA polymerase gamma 35kD Overexpression of DNApol-gamma35 (DNA polymerase gamma) in the nervous system results in a decrease in the median lifespan ranging from 39% to 52% [17999718]. Fruit fly
    Dys Dystroglycan Loss of dys function in the heart leads to an age-dependent disruption of the myofibrillar organization within the myocardium as well as to alterations in cardiac performance. dys RNAi-mediated knockdown in the mesoderm also shortens lifespan. Mesodermal dys knockout results in a morderate maximum lifespan reduction (13%), but not when exclusively targeted to the heart. In contrast, half of the transheteozygous DysExel618/Dyskx43 deficiency flies die at 29 days compared to 63 days in controls. This indicates that a moderate dye loss-of-function in all muscles, but not in just the heart, reduces the normal lifespan [18221418]. Fruit fly
    E(z) Enhancer of zeste Flies heterozygous for the protein null E(z)63 or the catalytically inactive E(z)731 mutation that are progeny of an out-cross to an Oregon-R (O-R) wild-type strain exhibit a substantially greater median lifespan than the O-R control (71% and 76%, respectively). When derived from an out-cross to a longer-lived Canton-S (C-S) wild-type strain, the median lifespan of E(z)63 heterozygous is 33% longer than the C-S control [20018689]. Fruit fly
    EcR Ecdysone receptor Mutant heterozygotes in EcR live on mean 40%-50% longer than controls [12610309; reviewed in 12610294]. Homozygous mutants in EcR are inviable. The developmental time and weight of EcR+/- mutants is the same as control, but resistance to temperature, oxidative stress, and starvation is increased in heterozygotes [12610309]. Fruit fly
    Edem1 The mean lifespan of Edem1 mutants of both male and female is increased by more than 30% [19302370]. Fruit fly
    Ef1alpha48D Elongation factor 1alpha48D Overexpression of Ef1alpha48D (transformed with a P-element vector and under control of hsp70 regulatory sequences) results in lifespan extension by 18-41%. The decrease in protein synthesis that accompanies aging is preceded by a decrease in EF-1 alpha protein and mRNA [2508089]. Fruit fly
    Eip71CD Ecdysone-induced protein 28/29kD Overexpression of Eip71CD (alias MsrA) in nervous system extends the lifespan by up to 70%, increased resistance to oxidative stress, and delays the onset of senescence-induced decline in activity levels and reproductive capacity. Eip71CD is a downstream effector of foxo [22310715]. Mean and maximum lifespan is increased by up to 2-% in animals that overexpress Eip71CD [20655917]. Fruit fly
    elav embryonic lethal abnormal vision elav mutation significantly decreases the lifespan. Median lifespan in males is 66% lower [20589912]. Fruit fly
    esc extra sexcombs Males heterozygous for the null esc4 or the dominant negative esc9 mutation that are progeny of an out-cross to a O-R wild-type strain have median lifespan that is, respectively, 47% and 60% longer than the O-R control. When derived from an out-cross to a longer-lived C-S wild-type strain, heterozygous esc9 flies have a median lifespan that is 43% longer than the C-S control [20018689]. Fruit fly
    fh frataxin homolog Overexpression of fh in the mitochondria of female transgenic animals increases antioxidant capability, resistance to oxidative stress insults, and longevity [18258192]. Fruit fly
    foxo Forkhead box, sub-group O foxo overexpression extends lifespan. Activation of foxo in the adult pericerbral fat body is sufficient for lifespan extension [15175753]. Overexpression of foxo in the adult adipose tissue alone prolongs lifespan [15192154; 15175753]. Limited activation of foxo reduces the expression of Drosophila insulin-like peptide dilp-2 synthesized in neurons and, represses endogenous insulin-dependent signaling in peripheral fat body [15175753]. foxo is not required for DR, but its activity modulates the response. foxo null mutants are highly and significantly shorter-lived than wild-type on all food dilutions apart from 0.1 SY and under starvation. foxo null mutants are not more sensitive to starvation than wild-type. foxo overexpression in adult fat body under normal nutritional conditions leads to extension of lifespan of females and causes a right shift of the response curve of lifespan to DR [18241326]. Overexpression of dFOXO in adult fat body increases median, by 21-33%, and maximum lifespan as well as lowers the age-specific mortality at all ages, in two independent experiments. Overexpression of dFOXO increases lifespan by lowering the whole mortality trajectory, with no effect on slope (similar to DR). Initiation of dFOXO expression at different ages increases subsequent lifespan with the magnitude of increase decreasing as the animals were put on RU486 (which activates the foxo transgene via UAS) at older ages. The effects of removal of dFOXO overexpression at different ages closely mirrored those of induction of expression and produce shortest lifespan observed in animals taken of RU486 at the earlier ages [17465980]. Fruit fly
    g garnet Loss-of-function mutation in g reduces mean lifespan by 11 - 42% and maximum lifespan by 7 - 30% [17435236]. Fruit fly
    Gadd45 growth arrest and DNA damage-inducible gene 45 Gadd45 overexpression in the nervous system leads to a significant increase of lifespan without a decrease in fecundity and locomotor activity. The lifespan extension effect is more pronounced in males than in females. Additional maximum lifespan is also extended. The maximum lifespan is increased by 50% and 59% for females and males, respectively. The median lifespan is extended by 46 and 77% for females and males, respectively [22661237]. Fruit fly
