摘要:

目的 探讨五子衍宗丸对卵巢储备功能减退小鼠的治疗作用及潜在机制。 方法 利用雷公藤多苷建立卵巢储备功能减退小鼠模型,将雌性C57BL/6J小鼠随机分为对照组、模型组、五子衍宗丸低剂量组(五子衍宗丸-L,1.82 g·kg-1·d-1)和五子衍宗丸高剂量组(五子衍宗丸-H,3.64 g·kg-1·d-1),8只/组,灌胃给药28 d。计算小鼠卵巢指数,通过ELISA检测激素水平,HE染色观察卵巢组织形态。利用RNA-seq筛选五子衍宗丸治疗卵巢储备功能减退的关键信号通路。结合网络药理学,使用多重数据库分析五子衍宗丸的潜在作用靶点与通路。通过免疫组化和Western blotting检测小鼠卵巢组织中TGF-β1/PI3K/Akt/mTOR通路关键蛋白表达,TUNEL染色及Western blotting评估颗粒细胞(GCs)凋亡水平。此外,收集人GCs样本进行Western blotting,验证该通路在卵巢储备功能减退患者中的表达。 结果 与模型组相比,五子衍宗丸使卵巢指数恢复(P<0.05),抗缪勒管激素及雌二醇水平升高,卵泡刺激素降低(P<0.05),并改善卵巢组织形态,使GCs功能恢复,闭锁卵泡减少。RNA-seq显示PI3K/Akt通路在五子衍宗丸治疗后显著富集。网络药理学显示,TGF-β、PI3K-Akt及凋亡通路是五子衍宗丸潜在作用的关键通路。免疫组化及Western blotting提示五子衍宗丸上调卵巢组织TGF-β1、PI3K、Akt和mTOR蛋白表达(P<0.05),TUNEL染色及Western blotting表明五子衍宗丸抑制GCs凋亡(P<0.05)。卵巢储备功能减退患者GCs中TGF-β1/PI3K/Akt/mTOR通路蛋白表达下调(P<0.05)。 结论 五子衍宗丸通过上调TGF-β1/PI3K/Akt/mTOR信号通路,抑制GCs过度凋亡,从而改善卵巢储备功能。

Abstract:

Objective To investigate the efficacy of Wuzi Yanzong Pill (WZYZP) for improving diminished ovarian reserve (DOR) in mice and explore the underlying mechanism. Methods Female C57BL/6J mice were randomly divided into control group, Tripterygium wilfordii polyglycoside-induced DOR model group, and two WZYZP groups treated with WZYZP at daily doses of 1.82 or 3.64 g/kg for 28 days (n=8). Ovarian index of the mice was calculated, hormone levels were detected with ELISA, and ovarian histopathological changes were observed using HE staining. RNA sequencing was performed to identify the key signaling pathways involved in WZYZP treatment for DOR. Network pharmacology analysis was used to predict the potential targets and pathways of WZYZP. Immunohistochemistry and Western blotting were used to detect ovarian expressions of the key proteins in the TGF‑β1/PI3K/Akt/mTOR pathway. Granulosa cell (GC) apoptosis levels were assessed with TUNEL staining and Western blotting. In addition, human GCs samples were collected from DOR patients for validating the expressions of the TGF‑β1/PI3K/Akt/mTOR pathway using Western blotting. Results In the mouse models of DOR, WZYZP treatment significantly improved the ovarian index, increased anti-Müllerian hormone (AMH) and estradiol (E2) levels, decreased follicle stimulating hormone (FSH) level, alleviated ovarian pathologies, enhanced GC function, and reduced atretic follicles. RNA-seq revealed significant enrichment of the PI3K/Akt pathway after WZYZP treatment. Network pharmacology analysis suggested that the TGF‑β, PI3K‑Akt, and apoptosis pathways were the key pathways potentially targeted by WZYZP. WZYZP treatment significantly upregulated the expressions of TGF‑β1, PI3K, Akt, and mTOR in mouse ovarian tissues and inhibited GC apoptosis. Western blotting of human GCs further verified the down‑regulation of TGF‑β1/PI3K/Akt/mTOR pathway in DOR patients. Conclusion WZYZP improves ovarian reserve by upregulating the TGF‑β1/PI3K/Akt/mTOR signaling pathway and inhibiting excessive apoptosis of GCs.
