Study on mechanism of regulation of sex hormones in treatment of hyperprolactinemia-induced ovulatory disorder infertility with Bushen Culuan Formula
Transcriptomics was used to investigate the mechanism of action of Bushen Culuan Formula in the treatment of infertility caused by hyperprolactinemia(HPRL),and animal experiments were carried out to verify the results.After establishing an animal model of HPRL-induced infertility,the mice were divided into normal group,model group,Bushen Culuan Formula groups with high-,medium-,and low-doses,and bromocriptine group,and they were observed in terms of the estrous cycle,gonadal index,serum sex hormones,morphology of ovary and mammary gland,follicle count,and fertility.The results showed that the Bushen Culuan Formula could effectively restore the estrous cycle,down-regulate the levels of prolactin(PRL),follicle-stimulating hormone(FSH),and luteinizing hormone(LH),up-regulate the level of estradiol(E2),increase the number of primordial follicles and sinus follicles,and improve the ovulation rate and fertility of mice.Through RNA sequencing combined with biosignature analysis,Bushen Culuan Formula may regulate the metabolism of lipids,antioxidant enzymes,and other substances in the cells of the ovary and pituitary gland through the signaling pathways of cAMP-PKA,Kiss-1/GPR54,and Hippo and exert therapeutic effects.The results of animal experiments showed that Bushen Culuan Formula could up-regulate serum dopamine(DA)level and pituitary DRD2 expression,down-regulate hypothalamus and ovary cAMP levels,as well as protein expressions of the pituitary gland and ovary PKA,CREB,and p-CREB,and treat HPRL-induced infertility by regulating the cAMP-PKA signaling pathway.
