This review discusses how FOXO transcription factors integrate ovarian and uterine hormonal cues with stress, growth factor, and cytokine signals to regulate processes essential for reproductive tract remodeling, including cell-cycle arrest, oxidative stress responses, differentiation, and apoptosis. It links aberrant FOXO expression or activity to reproductive disorders such as endometriosis, endometrial cancer, primary ovarian insufficiency, and pregnancy failure, and summarizes evidence across model organisms and pathway mechanisms like evolutionary conservation. A major limitation is that the article is a narrative review, presenting associations and mechanistic framing rather than reporting new original experimental results or quantifying effect sizes. Relevance to endometriosis: endometriosis is explicitly listed among disorders linked to aberrant FOXO transcription factor expression or perturbed activity, though the paper’s main focus is FOXO biology in female reproductive tract disorders broadly.

Abstract

All fundamental reproductive events in the human ovary and uterus, including ovulation, implantation and menstruation, are dependent upon profound tissue remodelling, characterized by cyclical waves of cell proliferation, differentiation, recruitment of inflammatory cells, apoptosis, tissue breakdown and regeneration. Although the rise and fall in ovarian hormones, estradiol and progesterone, orchestrate these reproductive events, FOXO transcription factors, an evolutionary conserved subfamily of forkhead transcription factors, have emerged major downstream effector molecules, capable of integrating hormonal cues with a variety of stress, growth factor and cytokine signal transduction pathways. 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 the reproductive tract. Aberrant expression or perturbed activity of FOXO transcription factors are increasingly linked to prevalent reproductive disorders, such as endometriosis, endometrial cancer, primary ovarian insufficiency and pregnancy failure, which in turn highlights their potential as therapeutic targets.
