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

    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
    Bmcp Mitochondrial uncoupler Bmcp knockout flies live longer on low-calorie diets, have a decreased fertility, and gain less weight on high-calorie diets. Bmcp (ucp5) knockout mutants live longer than wild-type on low-calorie diets, but no longer on starvation or high-calorie diets. Ectopic neuronal expression of Bmcp transgene rescues starvation sensitive phenotype of Bmcp knockout mutants [16387864]. Fruit fly
    bwa brain washing bwa (alias Dacer) inactivation increases Drosophila pre-adult development time and anti-oxidative stress capacity. Mean lifespan is increased by 16% in females, by 21% in males and by 19% in total. Maximum lifespan of females, males is also extended by 20 and 12%, respectively [20112046]. Fruit fly
    dnc dunce cAMP phosphodiesterase-deficient dunce mutants have an extended maximum lifespan by about 70% [17369827]. Fruit fly
    esg Escargot Disruption of esg by insertion of the P{GT1} vector 300 bp downstream of its structural part increases male and female lifespan. Heterozygous esg and insc double mutants interact in the course of lifespan determination. The decrease of esg transcription is associated with lifespan increase in mutant esg and insc flies [22661237]. Fruit fly
    Tor Target of rapamycin Expression of a dominant-negative form of Tor extends lifespan [15186745]. Ubiquitious overexpression of dTOR with the da-GAL4 driver of UAS-dTOR(FRB) which contains the 11kDA FKB12-rapamycin binding domain led to a mean and maximum lifespan increase of 15% (24%) and 29% at 29°C and of 50% (26%) and 13% at 25°C, respectively [15186745]. Overexpression of the dominant-negative form of Tor specifically in the fat and muscle tissues is sufficient to extend the mean and maximum lifespan by 24 and 19%, respectively [15186745]. Overexpression of UAS-dTOR(WT) or UAS-dTOR(TED) prevents eclosion to adulthood [15186745]. Fruit fly
    mld molting defective Female, but not male, heterozygous mutants display a 42% increase in mean lifespan at 29 degrees Celsius. DTS-3 +/- female adults exhibit a 50% reduced ecdysone titer and reduced fertility [12610309]. Female, but not male, heterozygoutes also exhibit a temperature-dependent increase in starvation resistance. Fruit fly
    l(3)DTS3 lethal (3) DTS3 Female, but not male, heterozygous mutants exhibit a 42% increase in mean lifespan and resistance to various stresses, with no apparent deficit in fertility or activity [12610309]. Fruit fly
    Indy I'm not dead yet Flies heterozygotic for a disruption in Indy gene have extended mean (87-92%) and maximum (45%) lifespan. Homozygotes for the disruption show only a 10 - 20% increase in mean lifespan [11118146]. Heterozygous insertion of a p-element in the non-coding region of Indy locus leads to a reduction in Indy mRNA expression and causes a significant median lifespan extension in male and female by about 29% and 34%, respectively. At normal or high calorie conditions Indy heterozygote mutants have a significant lifespan extension, but under low calorie conditions, Indy heterozygous mutants have minimal median lifespan extension. Reduction of calorie content from high to normal calorie condition results in 19% decline in Indy mRNA and from normal to low calorie condition results in additional 9% decrease in Indy mRNA. Reduction of calorie content from high to normal calorie conditions in heterozygous Indy mutants leads to 20% reduction in Indy mRNA expression without any additional decrease upon further reduction to low calorie food. Maximum lifespan extension is associated with Indy mRNA levels between 25 - 75% of normal. Long-lived heterozygous Indy mutants on high-calorie food and normal wild-type on low-calorie food have several phenotypes in common: 50 - 60 % reduced mRNA expression levels of Ilp2, Ilp3 and Ilp 5; similar high percentage of anti-FOXO-positive nuclei in fat body cells; higher sensitivity to starvation; do not gain weight; similar decrease in triglycerides and fat storage; normal food intake [19470468]. Mutations in Indy dramatically extend lifespan without a loss in fertility, physical activity, flight velocity or metabolic rate [11118146; 12626742]. Indy encodes a high-affinity dicarboxylate/citrate plasma membrane transporter found most abundantly in adult fat body, oenocytes and midgut cells, the primary sites of intermediary metabolism [12391301]. Indy mutation alters metabolism in a manner similiar to DR and mutants have several phenotypes with long-lived DR files in common, including decreases insulin-like signaling, lipid storage, weight gain, and resistance to starvation, and an increase in spontaneous physical activity [19470468]. Of the Indy206 and Indy302 mutation only one of the two has lower mRNA levels and both do not extend lifespan of female flies in any genetic background. In original genetic background only Indy mutation associated with altered RNA expression extends the lifespan of males. This effect is abolished by back-crossing into standard out-bred genetic backgrounds and is associated with an unidentified locus on the X chromosome. Original Indy line with long-lived males is infected by the cytoplasmic Wolbachia. Longevity of Indy males disappear after tetracycline clearance of this endosymbiont [17571923]. 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
    Ilp2 Insulin-like peptide 2 Flies with an ablation of median neurosecretary cells (which eliminates Ilp2 expression) exhibit a significant increase in mean and maximum lifespan over that of control flies and an increase to oxidative stress and starvation. The mutants also exhibit increased storage of lipid and carbohydrate, reduced fecundity, and reduced tolerance of heat and cold [15708981]. The median and maximum lifespan of females is increased by 33.5% and 40%, respectively. In males the median and maximum lifespan is increased by 10.5% and 27%, respectively [15708981]. Ilp2 RNA interference results in a 24% to 47% increase in median lifespan [19005568]. Ilp2 is transcriptional down-regulated in long-lived mutants. Ilp2 null mutants are significant longer-lived with a 8-13% longer median lifespan, but have a normal DR response. Ilp2 Ilp3 Ilp5 triple null mutants fail to have a normal response to DR. Their response is right shifted, with mutants shorter-lived compared to wild-type on low but longer-lived on high yeast concentrations [20195512]. Fruit fly
    Gr63a Gustatory receptor 63a Gr63a loss-of-function in female flies leads to 30% extended mean lifespan, increased fat deposition, and enhanced resistance to some (but not all) environmental stresses. Lifespan of males is not extended [20422037]. Overexpression of Gr63a has modest negative effect on lifespan [20422037]. Fruit fly
    puc puckered Heterozygous loss-of-function mutations in puc (either pucA241.1 or pucE69) significantly extend median and maximum lifespan and increase resistance to oxidative stress. Heterzyogosity for puc only modestly extends lifespan in animals carrying a hypomorphic allele of the JNK kinase hep [14602080]. puc heterzyogotes do not differ signficantly from wild-type for body size, reproductive activity or developmental timing, but exhibit increased resistance to oxidative stress and starvation [14602080]. Fruit fly
    insc inscuteable insc disruption through an insertion of the P{EPgy2} vector in ts structural part prolongs female lifespan. Heterozygous esg and insc double mutants interact in the course of lifespan determination. The decrease of esg transcription is associated with lifespan increase in mutant esg and insc flies [22661237]. Fruit fly
    aPKC atypical protein kinase C Insertion of a P-based vectors in the structural part of aPKC increase male and female lifespan [22661237]. Fruit fly
    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
    bchs blue cheese Loss of function mutation in bchs results in a 40-45% decrease in mean lifespan and is associated with age-related neurodegenerative phenotype with reduced CNS size and altered morphology as well as accumulation of insoluble ubiquinated proteins and amyloid precursor-like proteins along with an increase in neuronal apoptosis. No pronounced developmental defects were observed and young adults have normal behaviours, indicating that the bchs gene is essential for normal adult survival and longevity [12598614]. bchs mutation reduces mean lifespan by 28 - 54% and maximum lifespan by 24 - 46% [17435236]. Alfy (autophagy-linked FYVE protein) is the conserved human bchs homolog [15292400]. Fruit fly
    Lnk Loss of Lnk function results in increased median (14% in females and 17.5 in males) and maximum lifespan, reduced female fecundity and improves survival under conditions of oxidative stress and starvation. Heterozygousity does not result in any significant differences in lifespan in either males or females. Moreover, lifespan extension in one of the female homozygous mutant is fully rescued by the introduction of a Lnk genomic rescue construct [20333234]. Fruit fly
    Orco Odorant receptor co-receptor Loss-of-function mutation in Orco (alias Or83b) results in olfactory defects, altered adult metabolism, enhanced stress resistance, and life-extension. Fully fed female homozygous Or83b null mutants exhibit a 56% increase in median lifespan and a 30% increase in maximum lifespan. Males are also significantly longer-lived, though to a smaller degree and maximum lifespan is not extended. Heterozygous mutants of both sexes show an intermediate longevity. Lifespan of homozygous Orco null mutants is further increased by DR, but the relative increase in median and mean longevity is significantly greater when mutants were maintained in well-fed conditions [17272684]. Fruit fly
    Rpd3 Histone deacetylase Rpd3 Males heterozygous for hypomorphic (partial loss-of-function) or null mutation of Rpd3 have a lifespan extension of 33% and 41 - 47%, respectively. Females heterozygous for a hypomorphic allele have a 52% increase in lifespan, but females carrying a null mutation have only modest increase in maximum lifespan (but not median lifespan). Longevity increases to the same extent in wild-type under low-calorie diet and rpd3 mutants fed normal diet. DR fails to further increase lifespan of rpd3 mutants. DR leads to a moderate but significant down-regulation of Rpd3, analogous to decrease obtained in heterozygotes carrying rpd3 mutation. rpd3 mutants fed normal food and wild-type fed low-calorie increase Sir2 expression two-fold [12459580]. 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
    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
    mth methuselah Mutants in mth display approximately 35% and 36% increase in average and maximum lifespan as well as enhanced resistance to various forms of stress (including starvation, high temperature, and dietary paraquat) [9794765]. Reduced expression of mth targeted only to the insulin-producing cells of the brain is sufficient to extend lifespan and to enhance oxdative stress resistance [23121290]. IPC-targeted overexpression of β-arrestin alone mimics the longevity phenotype of reduced mth signaling [23121290]. Fruit fly
    chico Insulin receptor substrate-1 Mutation in chico extends mean, median, and maximum lifespan by 56%, 48%, and 42% in homozygotes and 44%, 36%, and 35% in heterozygotes. chico mutation produces dwarf, long-lived females at normal nutrition. Male heterozygous live 13% longer than wild-type, but male homozygous have a shortened lifespan [11292874]. Wild-type and chico mutant females have similar peak lifespan under DR, but the food concentration at which these are achieved is shifted to higher amounts. chico mutation induces a state equivalent to submaximal, DR-induced slowing of aging [11951037]. chico heterzoygous females have a reduced fecundity and homozygous recessive mutants are sterile. chico heterozygous mutants are resistant to starvation but not oxidative stress or temperature stress [11292874].
