Abstract
- Background: Since the human papillomavirus vaccines do not eliminate preexisting infections, nonsurgical alternative approaches to cervical intraepithelial neoplasia (CIN) have been required. We previously reported that FOXP4 (forkhead box transcription factor P4) promoted proliferation and inhibited squamous differentiation of CIN1-derived W12 cells. Since it was reported that FOXP expressions were regulated by the androgen/androgen receptor (AR) complex and AR was expressed on the CIN lesions, in this study we examined the effects of androgen on CIN progression.<br />Methods: Since AR expression was negative in W12 cells and HaCaT cells, a human male skin-derived keratinocyte cell line, we transfected AR to these cell lines and investigated the effects of dihydrotestosterone (DHT) on their proliferation and squamous differentiation. We also examined the immunohistochemical expression of AR in CIN lesions.<br />Results: DHT reduced the intranuclear expression of FOXP4, attenuating cell proliferation and promoting squamous differentiation in AR-transfected W12 cells. Si-RNA treatments showed that DHT induced the expression of squamous differentiation-related genes in AR-transfected W12 cells via an ELF3-dependent pathway. DHT also reduced FOXP4 expression in AR-transfected HaCaT cells. An immunohistochemical study showed that AR was expressed in the basal to parabasal layers of the normal cervical epithelium. In CIN1 and 2 lesions, AR was detected in atypical squamous cells, whereas AR expression had almost disappeared in the CIN3 lesion and was not detected in SCC, suggesting that androgens do not act to promote squamous differentiation in the late stages of CIN.<br />Conclusion: Androgen is a novel factor that regulates squamous differentiation in the early stage of CIN, providing a new strategy for nonsurgical and hormone-induced differentiation therapy against CIN1 and CIN2.<br /> (© 2023 The Authors.
