摘要
Luteal phase deficiency (LPD) is a significant contributor to infertility and miscarriage. Bushen Zhuyun Prescription (BSZY) is a traditional Chinese medicine formula that has potential to treat LPD. To investigate the effect of BSZY in treating LPD, SD rats with complete estrous cycles were divided into blank, model, dydrogesterone (DYD), high-dose BSZY (BSZY-HD), and low-dose BSZY (BSZY-LD) groups. All the groups were received mifepristone gavage except for the blank group. The pathological changes were observed in the hypothalamus, and the analysis of follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2), progesterone (P), gonadotropin-releasing hormone (GnRH), and cyclic adenosine monophosphate (cAMP) levels in serum. Additionally, the mRNA and their protein expression levels of estrogen receptor α (ERα), ERβ, G protein-coupled receptor 30 (GPR30), kisspeptin 1 (Kiss1), and GPR54 were assessed; and the key molecules expression in cAMP/protein kinase A (PKA) pathway were analyzed. The results revealed that mifepristone treatment caused a decrease in FSH and cAMP levels and an increase in E2 and LH levels, which were normalised in the BSZY treatment groups. The expression of ERα and ERβ mRNA and protein in the hypothalamus was higher in the BSZY groups compared to the blank group. BSZY also resulted in increased expression of Kiss-1, GPR54, and PKA, as well as decreased expression of cAMP-response element binding protein (CREB), c-Fos, phospho-CREB (p-CREB), and p-c-Fos, compared to model group. No significant difference observed in GPR30 expression between the mifepristone and BSZY groups. The mRNA and protein of Kiss1 and GPR54 were decreased in model group and increased after BSZY treatment, while the mRNA and protein expression of PKA, CREB, c-Fos, p-CREB, and p-c-Fos were also decreased significantly. In conclusion, the findings demonstrate that BSZY could effectively regulate hypothalamic ER, interfere with the Kiss1/GPR54 signal transduction system, activate the cAMP/PKA pathway, and regulate key transduction molecules expression of PKA, CREB, c-Fos, there by effecting the level of reproductive hormones and has the potential to treat LPD-related infertility.
