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

    Sirt6 sirtuin 6 (silent mating type information regulation 2, homolog) 6 (S. cerevisiae) Sirt6 knockout mice develop signs of premature ageing including a short lifespan [16439206]. Overexpression of Sirt6 in male mice lengthens the median lifespan by 9.9-14.5% and maximum lifespan by 13.1-15.8% [22367546]. Mice without Sirt6 have a higher risk of gastrointestinal cancers. SIRT6 dampens cancer growth by repressing aerobic glycolysis (i.e. conversion of glucose to lactate; a major feature of cancer cells). Loss of Sirt6 increases the number, size and aggressiveness of tumors. Sirt6 loss leads to tumor formation even without activation of oncogenes. Transformed SIRT6-deficient cells exhibit increased glycolysis and tumor growth. Sirt6 inhibits the transcriptional activity of the oncogene Myc via corepression [23217706]. Sirt6 also protects against diet-induced obesity [http://www.biocompare.com/Life-Science-News/127206-Anti-Aging-Gene-Identified-As-Tumor-Suppressor-In-Mice-Research-Finds/]. House mouse
