Potential relevance to the human ageing process

Main reason for selection

Entry selected based on evidence linking the gene or its product to human longevity and/or multiple age-related phenotypes

Description

A transcription factor of the Fox family, FOXO3, is crucial in development [802]. It also appears to regulate apoptotic signals in conjunction with FAS and AKT1.

A homologue of FOXO3, daf-16, has been associated with ageing in roundworms [628], and overexpression of another homologue, dFOXO, in adult fat body of fruit flies increased longevity in females [1238]. Female mice without FOXO3 showed an ovarian phenotype of follicular activation leading to oocyte death, early depletion of functional ovarian follicles, and secondary infertility [625].

Two studies of genetic variation within FOXO3, have found it to be associated with exceptional human longevity, among people of Japanese [1987] and German [1983] origin. The G allele of FOXO3 single nucleotide polymorphism (SNP) rs2802292 has been associated with longevity in multiple populations. G-allele carriers among combined Japanese, white and black populations have a risk reduction of 10% for total mortality [4357].
