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

    Oo Olive oil In rats oral treatment with Olive oil (at the age of 10 month for 7 months) increases mean, median and maximum lifespan by 41, 18 and 53%, respectively. Olive oil extends the lifespan with a probability of 0.99 [22498298]. In humans olive oil has positive effects on health and counteracts aging [11905662]. Its effect is suggested to be a function of the dose [19369055]. Fruit fly
    Laz Lazarillo Extracellular forms of Laz have autocrine and paracrine protecting effects for oxidative stress-challanged Drosophila S2 cells. Local effects of GPI-linked Laz inside and outside the nervous system promote survival upon different stress forms, and extend lifespan and healthspan of the flies in a cell-type dependent manner. Ectopic enhancement of Laz expression increases mean, median, and maximum lifespan. Laz overexpression (via the use of a ubiquitous da-GAL4 driver) increases median lifepan by 28.3% (p < 0.0005). Overexpression of Laz specifically in muscles and brain (via GAL4109(2)80 driver) increases median lifespan by 43.5%. Laz overxpression in dopaminergic and serotenergic neurons and epidermis increases median lifespan bt 31.4% (p < 0.0005) [22846641]. Fruit fly
    PDTC Pyrrolidine dithiocarbamate Treatment of Drosophila imago with PDTC increases median (by 11-13%) and maximum (by 11-14%) lifespan in females and males, respectively [22661237]. Fruit fly
    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
