Abstract

Objectives: To investigate the therapeutic effect of Huluan decotion (, HLD) on cyclophosphamide-induced premature ovarian failure (POF) in mice and its regulatory mechanisms.

Methods: Female BALB/c mice were administered cyclophosphamide and administered received different doses of HLD for 28 d. Levels of sex hormone, such as estradiol (E2), follicle stimulating hormone (FSH) and luteinizing hormone (LH) in the sera, were assessed using enzyme-linked immunosorbent assay (ELISA). Follicular structure variances were observed through hematoxylin and eosin (HE) staining, while Forkhead box L2 (FOXL2) expression were analyzed via immune-ohistochemical staining. The primary mechanism of POF were investigated through Western blot analysis.

Results: E2 levels decreased, and FSH and LH levels increased in POF model mice, but these trends were reversed with HLD or premarin administration, the expressions of WNT family member 4 (Wnt4), β-Catenin and FOXL2 were downregulated in POF model mice, whereas high expression levels were observed in control mice and other groups.

Conclusion: HLD effectively treats POF induced with cyclophosphamide in mice by enhancing expressions of Wnt4, β-Catenin and FOXL2.

葫芦丝汤对环磷酰胺所致小鼠自身免疫性卵巢早衰的影响。
目的:探讨葫芦丝汤对环磷酰胺致小鼠卵巢早衰(POF)的治疗作用及其调控机制。方法:雌性BALB/c小鼠分别给予环磷酰胺和不同剂量的HLD治疗28 d,采用酶联免疫吸附试验(ELISA)测定血清中雌二醇(E2)、促卵泡激素(FSH)和促黄体生成素(LH)水平。通过苏木精和伊红(HE)染色观察卵泡结构差异,免疫组织化学染色分析叉头盒L2 (FOXL2)表达。Western blot分析POF的主要机制。结果:POF模型小鼠E2水平降低,FSH和LH水平升高,但HLD或premarin组逆转上述趋势,WNT家族成员4 (Wnt4)、β-Catenin和FOXL2表达下调,而对照组和其他组均高表达。结论:HLD可通过提高Wnt4、β-Catenin和FOXL2的表达,有效治疗环磷酰胺诱导的小鼠POF。
