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

    CETP cholesteryl ester transfer protein, plasma Homozygousity for the I405V variant of CETP is associated with exceptional longevity and larger HDL and LDL particle sizes as well as lower prevalence of hypertension, cardivascular disease, and metabolic disease among Askenazi Jews [14559957]. CETP I405V homozygousity is associated with exceptional longevity and preservation of cognitive function in Askenazi Jews [17190939]. V/V homozygotes tend to have a 9-23% CETP deficiency [9610775; 15243211]. A decrease in CETP function increases HDL (high density lipoproteins) levels in the body, and decreases LDL (low-density lipoprotein). The result of this s that HDL-c levels are approximately equal in individuals with the I/I or I/V genotypes, while there are ten percent higher in V/V individuals [9610775]. Therefore the V/V SNP acts kind like an endogenous *CEPT inhibitor*, which might be the responsible for the increase in longevity but may also have side effects.CETP was found to be associated with longevity [22336474].CETP was found to be associated with longevity [15621216].CETP was found to be associated with longevity [15888337].

    Hsp70Ba Heat-shock-protein-70Ba Hsp70Ba overexpression reduces mean and maximum lifespan up to 30% [19420297]. hsp70 and hsp22 RNA levels are higher in long-lived than in short-lived fly lines. The HDAC inhibitor TSA causes a higher expression of hsp22 and hsp70, and strikingly influences the lifespan in both long and short-lived lines, with variable degrees (up to 25%) [15695762]. Fruit fly

    APOE apolipoprotein E In humans APOE is located on chromosome 19. There are three common allelic variants of APOE (ε2 to ε4). The resulting proteins are referred to as ApoE2, ApoE3 and ApoE4. The respective proteins differ only in single amino acid, but have a dramatic influence on the life of affected humans. The frequency of the epsilon 2 allele of ApoE is significantly increased in centenarians relative the overall control population, while the epsilon 4 allele is significantly decreased in centenarians [8136829]. Among individuals 85 years or older how had good cognition, the mortality of those that had the 2/3 genotype was half that in those who carried the epsilon 3/3 genotype and the mortality in subjects with the epsilon 3/4 genotype is twice that of those who carry the epsilon 3/3 genotype. This 4-fold variation results in 2-year difference in survival [8624216]. The epsilon 4 allele is also associated with higher cholesterol levels and cardiovascolar disease [10818513; 8624216] as well as risk factor for cognitive impariment under age 85 [8624216]. However the APOE polymorphism is not a risk factor for cognitive impairment in individuals older than 85 years [8624216]. The Polymorphism (E2, E3, and E4) was examined in a sample of 228 healthy Italian subjects (124 men and 104 women) aged 18-93, with the result that the frequency of E4 decreased with age and was not found in subjects aged 75 and older [8541369]. By Examining the common polymorphism was in 182 women and 100 men aged > 84 years and in 100 boys and 100 girls younger than 17 years (English, Cambridge) a difference between genotypes in the elderly women and the young sample was observed. However, this did not retain significance when the genotype frequencies of the young sample were adjusted to values expected from the allele frequencies on the basis of Hardy-Weinberg equilibrium and compared to observed genotypes in elderly men and women [9105559]. In a Braxiallian population the common polymorphism was examined in 70 elderly patients aged 80 years or more. No association was observed between the genotypes and longevity, though individuals with the E3E4 genotype had a mean age greater than those with the E3E3 genotype [12185856]. In a Korean population the common polymorphism examination of 103 centenarians (13 men and 90 women, mean age 102.4 +/- 2.6 years) and 6435 adults (5008 men and 1427 women) of mean age 50.7 +/- 7.9 years found that the frequencies of genotypes and alleles of the centenarians were not significantly different from those of the control groups. The frequency of the E4 allele was significantly higher in centenarians with dementia than in centenarians without definitive dementia [12634288]. Examination of the common polymorphism in 224 older (75 years) Jewish Jerusalem residents of Ashkenazi ethnicity (150 males and 74 females) and a group of 441 younger subjects (22 years) revealed that the Ashkenazi older subjects were characterized by an increased percentage of the E2 allele and a decreased percentage of the E4 allele [15621215]. A study of APOE polymorphisms in a samples of 538 Colombian subjects (aged 18-106 years) did not find any differences between young and old subjects [16971231]. APOE correlated highly with longevity in a plethora of genetic signatures and has been associated with Alzheimer's disease [22279548]. ε3 and *ε4 are much more efficient binding lipoprotein receptors [11882522]. The various APOE isoforms interact differently with specific lipoprotein receptors, ultimately altering circulating levels of cholesterol. APOE from VLDL, chylomirons and chylomicron remnants binds to specific receptor cells in the liver. Carriers of the *ε2 allele are less efficient at making and transferring VLDLs and chylomicrons from the blood plasma to the liver because of its binding properties. By contrast, carriers of the ε3 are much more efficient in these processes. While APOE4 and APOE3 bind with approximately equal affinity to lipoprotein receptors, APOE2 binds with less than 2% of this strength [7628082]. Thus, compared with carriers of the *ε3 or *ε4 allele, carriers of the *ε2 allele are slower to clear dietary fat from their blood [3479440]. The difference lipoprotein particles results in differences in regulating hepatic low density lipoprotein (LDL) receptors which in turn contribute to genotypic differences in total and LDL cholesterol levels [1998654; 3277611; 8696954; 8018666; 1867194; 3698268]. While APOE was not found to be associated with longevity in some studies [16799145; 21703254], APOE was found to be associated with longevity in many others [11780357; 11213279; 16487435; [23286790; 15621215; 8018664; 21418511; 8136829; 9792194; 22445811; 12185856; 10069711; 21703254; 17934638; 17234815; 11788960; 17934638; 10643896; 11280044; 14615589; 23040522; 18034366].

    GHR growth hormone receptor Individuals with low GH/IGF-I signaling due to a defect in the growth hormone receptor (GHR) are protected against cancer. Among the human individuals with a defect in GHR no cancer deaths were observed. GHR deficiency does not appear to extend lifespan because it is associated with increased risk of heart disease [21325617]. Variants in GHR were found to be associated with longevity [19489743].

    AKAP10 A kinase (PRKA) anchor protein 10 Male (n= 4766) and female (n = 6202) divided into young (183-9 years) and old (60 years) groups were examined for polymorphisms. A polymorphism that results in an amino acid change from Ile to Val showed the strongest correlation with age. The Val variant was associated with a statistically significant decrease in the length of the electrocardiogram PR interval. An A to G polymorphism in the 3'UTR of D-AKAP2 showed a significant decrease of the G allele in the older sample of both genders. Additionally, the I646V polymorphism was found to be significantly different between young and old in both males and females [12646697]. Human
    MIR21 MIRN21; hsa-mir-21; miR-21; miRNA21 MIR21 is the most highly expressed microRNA gene in octogenarians and centenarians. MIR21 expression is higher under cardiovascular diseases and lower in centenarian offspring. MIR21 is correlated with C-reactive protein and fibrinogen levels. TGF-βR2 mRNA, a MIR21 target, exhibits the highest expression in leukocytes form a subset of octogenarians. MIR-21 may be a biomarker of inflammation [23041385]. Human
    WRN Werner syndrome, RecQ helicase-like Mutation in WRN causes Werner Syndrome which characteristics includes prematurely aged facies, scleroderma-like skin changes, cataracts, arteriosclerosis, subcutaneous calcification, and diabetes mellitus [McKusick et al. 1963; 5327241]. Inheritance is autosomal recessive and malignancy is frequent. THe frequency is 3 per million individuals in Japan [7460386]. Cells from a Werner heterozygote exit the cell cycle at a faster rate than do normal cells [8265666]. Loss of WRN promoter aberrant mitotic recombination [11316787].
