Abstract: Aging is an inevitable risk factor for many diseases, including cardiovascular
diseases, neurodegenerative diseases, cancer, and diabetes. Investigation into the
molecular mechanisms involved in aging and longevity will benefit the treatment of
age-dependent diseases and the development of preventative medicine for agingrelated
diseases. Current evidence has revealed that FoxO3, encoding the transcription
factor (FoxO)3, a key transcription factor that integrates different stimuli in the
intrinsic and extrinsic pathways and is involved in cell differentiation, protein homeostasis,
stress resistance and stem cell status, plays a regulatory role in longevity and in
age-related diseases. However, the precise mechanisms by which the FoxO3 transcription
factor modulates aging and promotes longevity have been unclear until now.
Here, we provide a brief overview of the mechanisms by which FoxO3 mediates signaling
in pathways involved in aging and aging-related diseases, as well as the current
knowledge on the role of the FoxO3 transcription factor in the human lifespan and its
clinical prospects. Ultimately, we conclude that FoxO3 signaling pathways, including
upstream and downstream molecules, may be underlying therapeutic targets in aging
and age-related diseases.
