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

    Atg7 Autophagy-specific gene 7 Knockouts of Atg7 are short-lived with a 30% reduction in maximum lifespan and are hypersensitive to nutrient and oxidative stress [18056421; 19550147]. Fruit fly
    ImpL2 Ecdysone-inducible gene L2 Lmp-L2 over-expression, ubiquitous or restricted to DILP-producing cells and/or gut and fat body, extends lifespan even if induced at adult onset [21108726]. Overexpression of ImpL2 increases mean and maximum lifespan by 15% and 23%, respectively. Lifespan is reduced when Impl2 is strongly over-expressed throughout the adult by the conditional GS driver, act-GS-GAL4 or da-GS-Gal3, while restricted over-expression of the ImpL2 in fat cells by using S106-GS-Gal4, which increases mRNA level about 6-fold extends lifespan in both sexes [22366109]. mRNA for Impl2 was strongly elevated in sterile, long-lived flies [18434551]. 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
    dj-1beta dj-1β Loss of function mutation in dj-1beta shortens maximum lifespan by 40% and results in increased sensitivity to oxidative stress and motor impairments [17651920]. Fruit fly

    rb ruby Loss-of-function mutation reduces mean lifespan by 33% and maximum lifespan by 22% [17435236]. Fruit fly
    Zw Zwischenferment Mean lifespan of G6PD overexpressor flies is extended in comparison with driver and responder controls, armadillo-GAL4 (up to 38%), Tubulin-GAL4 (up to 29%), C23-GAL4 (up to 27%), da-GAL4 (up to 24%), D42-GAL4 (up to 18%) and Appl-GAL4 (up to 16%). The maximum lifespan is also increased [18809674]. G6PD enzymatic activity as well as levels of NADPH, NADH, and the GSH/GSSG ration are increased [18809674]. Fruit fly
    Dcr-2 Dicer-2 Median lifespan of homozyogous and transheterozyogous Dcr-2 mutants is reduced by 18-36% in males and by 27-36% in females. Dcr-2 loss changes the expression of mostly metabolic genes implicated in stress resistance and aging. Dcr-2 mutants are hypersensitive to oxidative, endoplasmic reticulum, starvation and cold stress as well as abnormal lipid and carbohydrate metabolism [21889502]. Fruit fly
    MTF-1 Metal response element-binding Transcription Factor-1 MTF-1 overexpression in either the peripheral nervous system or motorneurons extends both mean and maximum lifespan by 40% in males [18775584]. Fruit fly
    mir-14 mir-14 stem loop Mutating mir-14 decreases lifespan in both sexes. mir-14 reduces the mean and maximum lifespan of females by 55 and 36%, respectively, while those of males is reduced by 29 and 21%, respectively [12725740]. Fruit fly
    Atg8a Autophagy-related 8a Mutations in Atg8a results in reduced lifespan and increased sensitivity to oxidative stress while enhanced expression in older fly brains extends average adult lifespan by 56% and promotes resistance to oxidative stress [18059160]. Atg8a mutation reduces the maximum lifespan by 25% under starvation conditions [17617737]. Loss-of-function mutation in Atg8a reduces mean lifespan by 11 - 25% and maximum lifespan by 3 - 22% [17435236]. Fruit fly
    mys myospheroid mys mutants exhibit ameliorated age-related declines in locomotor activity and an increase in mean lifespan of 20% [14570233]. Fruit fly
    Naam Nicotinamide amidase Naam overexpression increases mean and maximum lifespan by 30% in both females and males. The lifespan extension is reversed by Sir2 mutants, indicating the it is dependent on Sir2 [18678867]. Fruit fly
    POSH Plenty of SH3s Neural-specific overexpression of POSH extends the mean lifespan of adult flies by 14% at 25°C. Ectopic expression of POSH during development results in morphological abnormalities [11868902]. Fruit fly
    Jafrac1 thioredoxin peroxidase 1 Neuronal overexpression of Jafrac1 significantly increases both mean and maximum lifespan, while neuronal knockdown as well as loss of function mutation, causes a reduction in lifespan by 30%. The mean lifespan is 26% and 29% higher in females and males, respectively. The maximum lifespan is increased by 22% and 26% in females and males, respectively [19720829]. There is a consistent and significant lifespan extension (15% mean lifespan increase) in both males and females when Jafrac1 is overexpressed in somatic cells. Jafrac1 overexpression using the weaker 5961FS driver moderately but significantly extends lifespan [20976250]. Fruit fly
    NF1 Neurofibromin 1 NF1 mutants have a shortened lifespan and exhibited increased vulnerability to heat and oxidative stress as well as reduced mitochondrial respiration and elevated ROS production. Overexpression of NF1 increases mitochondrial respiration and reduced ROS production. It increases mean lifespan by 49% in males and 68% in females and maximum lifespan by 38% in males and 52% in females. It also improved reproductive fitness [17369827]. Fruit fly
    Thor Null mutation in Thor (alias d4E-BP) causes a significant decrease in longevity (-25% median lifespan in males). Thor is strongly upregulated during starvation. foxo and Thor null mutants are compromised in stress resistant. Stress resistance of foxo null mutants is rescued by Thor overexpression [16055649]. Thor is upregulated on the protein level in a foxo-independent manner upon DR, while it is transcriptional induced in a foxo-dependent fashion by starvation. Thor null mutants cancel out DR-induced lifespan extension, because mutants exhibit a diminished change in lifespan when nutrient conditions were varied. Ubiquitously expression of Thor rescued DR response in females and males. Thor null mutants have a wild-type similar reduction in egg production upon DR. Ubiquitously overexpression of wild-type Thor causes no change under AL, but an activated allele (with more than 3-fold increased binding activity to delF4E) significantly extends lifespan of females (weak allele) and females as well as males (strong allele). Mean lifespan is extended by 11 to 40%. Median lifespan of males and females is enhanced by by 11 and 22%, respectively. Maximum lifespan is extended by 16 and 18% for males and females, respectively. Under DR (0.25% YE) there is no lifespan extension, beyond the effect of DR alone, in all (wild-type, weak and strong) Thor alleles [19804760]. Lifespan of animals with increased Pten and 4E-BP activity in muscle exhibit and extended mean and maximum lifespan by 20% and 15.8% [21111239]. Fruit fly
    Cct1 CTP:phosphocholine cytidylyltransferase 1 Overexpression of Cct1 from a doxycycline-inducible promoter results in a 6 - 8% increase in mean lifespan (in the PdL x rtTA; Oregon-R x rtTA strain) [12620118]. Cct1 exhibits a non-coding region difference unique to animals under experimental evolution selected for longevity and is upregulated in head of animals that were selected for longevity at all ages beyond the day of eclosion [23106705]. Fruit fly
