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

    (R)-N-(2-heptyl)-N-methylpropargylamine Addition of 0.66 ng/fly/day (R)-N-(2-heptyl)-N-methylpropargylamine to a sucrose-based diet resulted in no significant effect on lifespan, but lifespan reduction due to galactose feeding is partially suppressed by supplementation with (R)-deprnyl or (R)-N-(2-heptyl)-N-methylpropargylamine [9972869]. Fruit fly
    Pi3K92E Phosphatidylinositol-3-kinase Heterozyogous mutation in Pi3K92E fails to extend lifespan [11292874] and it is recessive lethal. Overexpression of a dominant-negative Pi3K92E (DP110) results in mutants that have impaired regeneration of the intestinal epithelium and are short lived with a reduction of the mean lifespan by 2.8% for males and 5.0% for females [20976250]. Fruit fly
    Cat Catalase Simultaneous overexpression of catalase and Sod1 results in a one-third (i.e. 30%) lifespan extension, a slower rate of mortality acceleration, and a delayed loss in physical performance, but neither has any effect on lifespan alone [8108730]. Targeted overexpression of CAT in the mitochondrial matrix has no effect on lifespan at 25 degree Celsius, slightly shortens lifespan at 29 degree Celsius as is associated with increased resistance to endogenous hydrogen peroxide, paraquat, and cold stress [12521602].
