Özet
Polycystic ovary syndrome (PCOS) is a complex reproductive and endocrine disorder affecting 5–10% of women of reproductive age, but the pathophysiology of PCOS still remains unknown. Here, the aim of our study was to analyze the effects of rapamycin treatment that may regulate impaired hormonal levels and folliculogenesis in dehydroepiandrosterone (DHEA)-treated PCOS mouse. We hypothesized that rapamycin may ameliorate the negative effects of PCOS in DHEA-induced PCOS mouse model. The target of rapamycin (TOR) gene product is a serine/threonine kinase that has been implicated in the control of cell growth, proliferation and autophagy, and rapamycin is a potent inhibitor of mTORC1 pathway. In this study, for the first time, mTORC1 and activation products are presented at protein and mRNA levels after rapamycin treatment in DHEA-induced PCOS mouse ovary. We showed that rapamycin treatment may regulate follicular development, hormonal levels and provide ovulation in DHEA-induced PCOS mouse. Additionally, we assessed decreased primordial follicle reserve, increased number of primary and secondary follicles, corpus luteum structure forms again after 10 days of rapamycin treatment. This study presented here suggests rapamycin treatment regulates hormonal phenotype and folliculogenesis in the ovary and also mTOR signalling pathway in granulosa cells of DHEA-induced PCOS mouse ovary which may have potential to attenuate understanding the mechanism of dominant follicle selection and anovulatory infertility.
