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

    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]. 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]. The single nucleotide polymorphism rs1800392 in WRN has been associated with exceptional longevity in a plethora of genetic signatures [22279548]. WRN was found to be associated with longevity [10069711; 20855428; 20855428; 20855428 ;17903295; 22406557; 16405962; 16405962; 16405962; 20855428; 20855428; 20855428; 22279548]. WRN was found to be associated with longevity [24244950]. Human
    TSHR thyroid stimulating hormone receptor Two single nucleotide in the TSHR were associated with increased TSH in both centenarians and their offspring [19837933].TSHR was found to be associated with longevity [19837933]. TSHR was not found to be associated with longevity [19837933]. Human
