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

    Met Methionine In yeast restriction of the methionine content in the culture extends mean and maximum lifespan by up to 29 and 16% (1/10 methionine content) [15141092].
    JUG Jugelone treatment High jugelone concentrations led to premature death. Low juglone concentrations are tolerated well and cause a prolongation of lifespan that is associated with increased expression of small heat-shock protein HSP-16.2, enhanced glutathione levels, and nuclear translocation of DAF-16. Silencing or deletion of daf-16 prevents jugelone-induced adaptations. RNA-interference for SIR-2.1 has the same effects as daf-16 deletion but does not affect nuclear accumulation of DAF-16. DAF-16- and SIR-2.1-dependent alterations in gene expression after challenge with reactive oxygene species lead to lifespan extension [19597959].
    NAM Nictoinamide adenine mononucleotide Treatment of budding yeast with NAM reduces mean and maximum replicative lifespan by 28 and 37%. NAM treatment blocks the lifespan extending effect of rapamycn [20947565]. Treatment of nematodes with NAM significantly decreases adult lifespan [17335870].
    git3 git3 encodes a G protein-coupled receptor for glucose. git3 deletion increases chronological lifespan in conditions where glucose consumption is not affected. Constitutive activation of the G-alpha subunit acting downstream of Git3 accelerates aging and inhibits the effect of DR. The anti-aging effect of DR and git3 deletion mutation is accompanied by increased respiration and lower ROS production [19266076]. Fission yeast
