The transcriptional regulators aryl hydrocarbon receptor (AHR) and aryl hydrocarbon receptor nuclear translocator (ARNT) modulate the transcription of genes involved in cellular differentiation and proliferation. In this study, we investigated the expression of these transcriptional regulators in the female reproductive tract. AHR and ARNT mRNA transcripts were readily detected by a ribonuclease protection assay in all reproductive tissues examined. The expression of these factors in the endometrium and myometrium did not vary during the menstrual cycle, and was not different in pre- versus post-menopausal women. However, post-menopausal women on continuous hormone replacement therapy had greater expression of AHR but not of ARNT in the endometrium and myometrium when compared with women not taking hormones. Leiomyomas expressed significantly less AHR and ARNT mRNA compared with normal myometrium. The ovaries expressed both AHR and ARNT mRNA, and expression was unaffected by age. Endometriotic ovarian cysts expressed more AHR but not more ARNT mRNA compared with healthy ovarian tissue. However, there were no changes in the expression of AHR or ARNT mRNA in ovarian cancer. In conclusion, the female reproductive tract expresses mRNA for the transcription factors AHR and ARNT, and changes in their expression at select target sites in specific pathological conditions such as endometriosis and uterine leiomyomas suggest a potential role for these factors in the pathogenesis of these conditions.
