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

    Quercitin Quercitin significantly extends the lifespan in C. elegans. Lifespan extension by quercitin has no effect on reproduction and body length. Quercitin induced lifespan extenison was neither dependent on a dietary restriction mimetic nor on sir-2.1 [19043800].
    LY294002 Treatment of Drosophila imago with 5 micromolar LY294002 increases median (by 14%) and maximum (by 16-22%) lifespan (p<0.001) in females and males, respectively [22661237]. Low dose of LY294002 (5 microM) slightly increase the median and maximum lifespan of fruit fly [20017609]. Fruit fly
    2-ME 2-Mercaptoethanol Animals fed a diet supplemented with 2-mercaptoethanol (2-ME) exhibit an increased mean and maximum lifespan [6334792]. T-cell-dependent immune responses are higher in the 2-ME-fed mice compared to the controls when the animals are young. The accumulation of fluorescent products of lipid peroxidation damage is also delayed in the lymphocytes of the 2-ME-fed mice and tumor onset and incidence is reduced in these animals [6334792]. House mouse
    2-MEA 2-Mercaptoethylanime hydrochloride Addition of 1% by weight 2-MEA to the diet of male LAF mice, started shortly after weaning, increases average lifespan by approximately 30%, but does not extend maximum lifespan [5723482; 11795501]. Addition of 2-MEA to the maternal diet of female mice increases the lifespan of male and female offspring by 15 and 8%, respectively [Harman & Eddy, 1979; 11795501]. Addition of 2-MEA of an antioxidant mixture containing ethoxyquin and 2-MEA to the diet of dietary restricted mice shortens lifespan approximately 20% [2394907]. References ---------------- Harman, D., and Eddy, D. E. (1979). Free radical theory of aging: beneficial effect of adding antioxidants to the maternal mouse diet on life span of offspring: possible explanation of the sex difference in longevity. Age 2, 109-22. House mouse
    DDS 4,4'-diaminodiphenylsulfone In nematode treatment with DDS extends the lifespan [20974969]. DDS causes the delay of aging and decreases the level of a mitochondrial complex as well as lowers oxygen consumption and enhances oxidative stress resistance [20974969]. Pyruvate kinase is bound and inhibited by DDS in vitro and in vivo [20974969]. Hansen disease patients in Korea, who usually have taken DDS for several decades, have a longer lifespan in spite of their socioeconomic disadvantages [19084552]. House mouse
    AP Apple polyphenol Apple polyphenols mainly consists of procyanidins, which are composed of (-)-epicatechins and (+)-catechins. Treatment of C. elegans with 100 microgram/mL apple polyphenol increases mean lifespan of wild-type N2 and FEM-1 by 12.0 and 5.3%, respectively [20717869]. In fruit flies, supplemention of the diet with apple polyphenol significantly extends mean lifespan by 10% and is accompanied by up-regulation of SOD1, SOD2 and CAT as well as downregulation of MTH in aged animals [21319854].
    Asc Ascrobate In budding yeast, the hypersensitivity to oxygene and significantly decreased replicative lifespan of SOD1 deletion can be ameliorated by exogenous ascorbate. If acorbate's negative effects of auto-oxidation are prevented by exchange of medium, ascorbate prolongs mean and maximum replicative lifespan in the atmosphere of air and pure oxygene [15621721].
    Beau I beauveriolide I In budding yeast treatment with beauveriolide I (20 microgram/mL) extends chronological lifespan in BY4741 by around 50% [22790951].
    BTE Black tea extract Black tea extract is a mixture of epicatechins and theaflavins. In fruit fly, upplementation of the diet with black tea extract extends the lifespan by 10% (from 51 to 56 days) and is associated with higher SOD1 and CAT expression [19770032].
    BBE Blueberry extract In fruit fly, supplementation of the diet with 5 mg/mL blueberry extract significantly extends the mean lifespan by 10% and is accompanied by an up-regulation of superoxide dismutase (SOD), catalase (CAT), and Rpn11 and down-regulationg of Methuselah (MTH). Lifespan is only extended in Oregon-R wild-type but not in SOD(n108) or Cat(n1) mutant strains [22197903].
    CSODM Carboxyfullerene SOD mimetic Administration of a small-molecule synthetic enzyme superoxide dismutase mimetic to wild-type (i.e. non-transgenic; non-senescence accelerated) mice starting at middle age significantly extends lifespan and reduces age-associated oxidative stress and mitochondrial radical production. Treatment also improves performance on Morris water maze learning and memory task and therefore rescues age-related cognitive impairment [17079053]. Carboxyfullerene SOD mimetic is an antioxidant with mitochondrial activity and nervous system penetration capability [17079053].
    Curcumin Curcumin increases lifespan in *C. elegans* and is associated with reduced ROS and lipofuscin during aging. Curcumin lifespan extension is attributed to its antioxidative properties. Lifespan extension had effects on body size and pharyngeal pumping rate but not on reproduction. Lifespan-extension by curcumin is abolished in osr-1, sek-1, mek-1, skn-1, unc-43, sir-2.1 and age-1 mutants, whereas curcumin treatment prolongs lifespan of mev-1 and daf-16 mutants [21855561]. *C. elegans* feed low concentration of curcumin have a decreased lipofuscin levels and enhanced the resistance to heat stress and increased mean lifespan by 39% and a maximum lifespan extended by 21.4% [23325575]. In fruit fly that survive an average of 64 days, an increase of mean lifespan to 80 days occurs in flies, with females of one strain and males of another strain experiencing an extension in lifespan. The lifespan response to curcimun exhibits variation in male and female, although the compound extends lifespan in both genders [23325575]. In fruit fly, 0.5 an 1.0 mg/g curcumin in the diet increases mean lifespan by 6.2 and 25% in females and by 15.5 and 12.6 in males, respectively. Lifespan extension by curcumin was associated with the increased superoxide dismutase (SOD) activity, upregulation of Ms-SOD and CuZn-SOD genes, and the downregulation of *dInR*, *ATTD*, *Def*, *CecB* and, *DptB* genes as well as reduction of lipofuscin, malondialdehyde and lipid peroxidation [22653297; 23325575]. Curcumin prolongs life and enhances activity of fruit fly Alzheimer diseased flies [22348084].
    CS Cynomorium songaricum In fruit fly, the yang-tonifying herbal medicine cynomorium songaricum Repr. (CS) supplementation to the diet extends both the mean and the maximum lifespan of adult females, but insignificantly that of males. In females, maximum lifespan (determined by the 90th survival percentile) is increased by up to 11.4% with 10 mg/mL CS and 5.7% with both 20 and 30 mg/mL Cs. Mean lifespan is significantly extended by 15, 18 and 11% upon treatment with 10, 20, and 30 mg/mL CS, respectively (all P <0.001). Increased lifespan by CS is correlated with higher resistance to oxidative stress and starvation and lower lipid hydroxyperoxids levels as well as accompanied by beneficial effects, such as improved mating readiness, increased fecundity, and suppresion of age-related learning impairment in aged animals [22844336].
    CYT1 cytochrome c1 Deletion of CYT1 increases replicative lifespan by 15% in the alpha strain and decreases replicative lifespan by 20% in a strain. Deletion of CYT1 decreases replicative lifespan and cancels out replicative lifespan extension by HAP4 overexpression. Initially, it was shown that deletion of CYT1 also prevents lifespan extension by 0.5% glucose restriction [12124627], but later it was shown that either 0.5 or 0.05 % glucose restriction increases replicative lifespan of cyt1Delta cells [16311627]. Budding yeast
    DCI D-chiro-inositol In fruit flies, D-chiro-inositol supplementation to the diet extends adult longevity in both male and female animals. 20 microMolar dose of D-chiro-inositol extends median lifespan by 16.7 (p < 0.001) for males and 13% (p < 0.001) for females. Lifespan extension by D-chrio-inositol is accompanied by protection against oxidative and starvation stresses, improvement in health span, and not reduction in fecundity. Nuclear localization of foxo increases in D-chiro-inositol-fed animals [22843669].
    DhHP-6 Deterohemin-AlaHisThrValGluLys Deuterohemin containing peptide deterohemin-AlaHisThrValGluLys (DhHP-6) significantly increases mean lifespan (P < 0.05), but not maximum lifespan. DhHP-6 also improves survival rate in acute heat-stress (35 degree Celsius) and rescues sensitivity to paraquat in acute oxidative stress. DhHP-6 treatment up-regulates SOD-3 and also regulates stress resistance genes such as hsp-16.1, hsp16.49 and sir-2.1 daf-16 and sir-2.1 genes are essential for the beneficial effect of DhHP-6 [20528576].
    Diabenol In female NMRI and transgenic HER-2/neu mice supplementation of diabenol with drinking water 5 times a week since the age of 2 months, increases survival and inhibits spontaneous carcinogenesis. In NMRI diabenol does not influence body weight gain dynamics, food and water consumption, but slowed down age-related disturbances in estrous function and increases the lifespan of all and 10% most long-living ones. Diabenol treatment in NMRI mice also inhibits spontaneous tumor incidence (mammary and lymphomas mainly) and increases mammary tumor latency. Diabenol treatment slows down age-related changes in estrous function in HER-2/neu mice, but fails to influence survival and slightly inhibited the incidence and decrease the size of mammary adenocarcinoma metastasis into the lung [15754958]. House mouse
    DATS Diallyl Trisulfide DATS increases longevity apparently by enhancing skn-1. Treatment with 5-10 μM DATS increases lifespan even when treatment is started during young adulthood. DATS increases the lifespan of daf-2 and daf-16 mutants, but not that of eat-2 mutants. DATS treatment leads to the induction of the skn-1 target gene gst-4 and this induction is dependent on skn-1. DATS effect on lifespan is dependent on skn-1 activity in both intestine and ASI neurons [21296648].
    DMSO Dimethyl sulfoxide Treatment with 0.5 and 2% DMSO increases lifespan by 24.4 and 23.0%, respectively. 0.5% DMSO does not affect progeny number or lifespan under thermal stress. Treatment with 0.5% DMSO enhances the mRNA levels of hsp-16.2, hsp-70, lys-7, old-1, and sod-5 by 2.5, 2.9, 1.3, 2.3, and 4.5-fold, respectively, as well as the protein level of lys-7 by 1.5-fold. Lifespan extension confered by DMSO depends on sir-2.1 and daf-16 but not on eat-2 or hsf-1 [20828537].
    SHE-3 Eleutherococcus senticosus Treatment of nematodes with the plant adaptogen Eleutherococcus senticosus (SHE-3; alias Acantopanax senticosus) increase stress resistance and mean lifespan in a dose-dependent manner. 250 microgram/ml SHE-3 signinifanclty increases lifespan between 10 and 20% 9 (P < 0.001), increase maximum lifepsan with 2-3 days and pospones the moment when the first individuals die. With higher concentrations, the effect is weakerm wheras at the highest concentrations (2500 microgram/mL) a lifespan shortenening effect of 15-25% (P < 0.001) occurs. Treatment with SHE-3 induces translocation of DAF-16 and activation of HSP-16 [18536978].
    Ganodermasides A Application of Ganodermasides A extends the replicative lifespan of budding yeast in K6001 strain by regulating UTH1 expression [20093034].
    Ganodermasides B Application of Ganodermasides B extends the replicative lifespan of budding yeast in K6001 strain by regulating UTH1 expression [20093034].
    Gonadermasides C In budding yeast application of gonadermasides C significantly increases the replicative lifespan in the K6001 strain by regulating UTH1 [21512225].
    Gonadermasides D In budding yeast application of gonadermasides D significantly increases the replicative lifespan in the K6001 strain by regulating UTH1 [21512225].
    Hesperidin Hesperidin derived from the Citrus genus extends replicative lifespan at doses of 5 and 10 microMolar. Hesperdin inihibts ROS and UTH1 gene expression, but increases Sir2 and SOD gene expression. UTH1 and SKN7 are involved in lifespan extension mediated by hesperidin [22484922]. Budding yeast
