Abstract :
مطالعات نشان دادهاند که استرادیول-17β (E2) هورمون آزاد کننده گنادوتروپین (GnRH) و بیان گیرنده GnRH در هیپوتالاموس و هیپوفیز را تنظیم میکند. مطالعات متعدد نشان دادهاند که GnRH و گیرنده آن در اندامهای تناسلی محیطی نیز بیان میشوند و اطلاعات کمی در مورد آن شناخته شده است. در این مطالعه، به ساختار، وظیفه، بیان محیطی GnRH و گیرنده GnRH و تنظیمات آن با E2 بررسی شد. مطالعات in vivoو in vitro نشان داد که E2 سبب کاهش بیان ژن GnRH و تنظیم بیان گیرنده GnRH به صورت وابسته به زمان میشود. با این وجود، مکانیسم دقیقی تاکنون به وضوح توضیح داده نشده است.
