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

    INS insulin Expression of human insulin under an inducible heat shock promoter increases nematode lifespan by 25% and is also able to enhance the lifespan of daf-2 mutants [11274053]. INS was found to be associated with longevity [22406557; 19367319; 17989723; 19489743]. 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
    UCP2 uncoupling protein 2 (mitochondrial, proton carrier) Overexpression of human UCP2 in the fly nervous system extends lifespan by 10-30%. Ubiquitous overexpression is lethal [16054055]. Human
