Multifaceted functions of the forkhead box transcription factors FoxO1 and FoxO3 in skin

摘要

Background: The ubiquitously expressed forkhead box, class O (FoxO) transcription factors act as signaling integrators in extensive transcriptional networks, ensuring maintenance of cell and tissue homeostasis over time and in response to environmental challenges. Proteins whose biosynthesis is controlled through FoxOs fulfil key functions in antioxidant defense, metabolism, cell cycle regulation and apoptosis.
