FOXO

Forkhead box O

Forkhead Box O (FOXO) is a subfamily within the forkhead box transcription factor family, characterized by having a highly conserved DNA-binding domain (FOX). FOXO family in mammals mainly consists of four members, namely FOXO1, FOXO3, FOXO4, and FOXO6. FOXO is involved in regulating key cellular processes such as apoptosis, cell cycle progression, and resistance to oxidative stress, and it is primarily regulated by Akt-mediated phosphorylation. FOXO family is closely related to diseases. It often acts as a tumor suppressor in tumors, can trigger insulin resistance and pancreatic islet β-cell dysfunction in diabetes, and is also involved in the occurrence and development of some neurodegenerative diseases. In addition, it also has the activities of resisting stress and extending lifespan[1].
