FOXO3

A gene on chromosome 6q21, which encodes a member of the forkhead family of transcription factors, which is thought to act as a trigger for apoptosis.
   
Molecular pathology
A translocation of FOXO9 with MLL is associated with secondary acute leukaemia.

TyrRS's activation of PARP-1 led, in turn, to the activation of a host of protective genes including the tumor-suppressor gene p53 and the longevity genes FOXO3A and SIRT6.
A variation in a single key gene called FOXO3A can triple the chances a person may live past 100, according to Sebastiani and colleagues in their Science article (15).
The gene, FOXO3A, is the second that's been shown to affect life span in people.
If the body were a company, FOXO3A would be a middle manager: It takes instructions from a few "big boss" molecules such as insulin, and in turn directs the activity of hundreds of other genes.
Scientists don't know how the variant of FOXO3A operates to boost longevity.
235) For example, PI3-K/AKT pathway activation by NPM-ALK inhibits FOXO3A (forkhead box O3A), leading to increased cyclin D2 expression and decreased transcription of genes that promote apoptosis [BCL2-like 11 (BIM)] and that negatively regulate the cell cycle (p27).
Kiel scientists have proved that 100-year-old Europeans carry a special sequence variation of the FOXO3A gene.
According to researchers, a variation in the gene FOXO3A has a positive effect on the life expectancy of humans, and is found much more often in people living to 100 and beyond - moreover, this appears to be true worldwide.
