All key reproductive events in the human ovary and uterus, including follicle activation, ovulation, implantation, decidualization, luteolysis and menstruation, are dependent upon profound tissue remodelling, characterised by cyclical waves of cell proliferation, differentiation, apoptosis, tissue breakdown and regeneration. FOXO transcription factors, an evolutionarily conserved subfamily of the forkhead transcription factors, have emerged as master regulators of cell fate decision capable of integrating avariety of stress, growth factor and cytokine signaling pathways with the transcription machinery. The ability of FOXOs to regulate seemingly opposing cellular responses, ranging from cell cycle arrest and oxidative stress responses to differentiation and apoptosis, renders these transcription factors indispensable for cyclic tissue remodelling in female reproduction. Conversely, perturbations in the expression or activity of FOXO transcription factors are increasingly linked to common reproductive disorders, such as pregnancy loss, endometriosis, endometrial cancer and primary ovarian insufficiency.

D000071161 Forkhead Box Protein O1 A forkhead box transcription factor that is a major target of INSULIN signaling and regulator of metabolic homeostasis in response to OXIDATIVE STRESS. It binds to the insulin RESPONSE ELEMENT (IRE) and the related Daf-16 family binding element (DBE). Its activity is suppressed by insulin and it also regulates OSTEOBLAST proliferation, controls bone mass, and skeletal regulation of GLUCOSE metabolism. It promotes GLUCONEOGENESIS in HEPATOCYTES and regulates gene expression in ADIPOSE TISSUE. It is also an important CELL DEATH regulator. Chromosomal aberrations involving the FOXO1 gene occur in RHABDOMYOSARCOMA. FOXO1 Protein,Forkhead in Rhabdomyosarcoma Protein
D000071316 Forkhead Box Protein O3 A forkhead box transcription factor and transcriptional activator which triggers type 1 programmed cell death (APOPTOSIS) in the absence of APOPTOSIS INHIBITING PROTEINS, including neuronal cell death induced by OXIDATIVE STRESS. It recognizes and binds to the DNA sequence 5'-(AG)TAAA(TC)A-3' and also functions in post-transcriptional regulation of the c-MYC PROTO-ONCOGENE.
