ETHNOPHARMACOLOGICAL RELEVANCE: Primary ovarian insufficiency (POI), which affects 3.7 % of women under age 40, is characterized by reduced ovarian function and infertility. Although Shoutai Pill (STW) is used for endocrine regulation, its mechanism in treating POI is unclear. Existing studies of POI have focused on ovarian damage, while the pathological changes in the uterus and its interactions with the ovary have not been clarified.
AIM OF THE STUDY: To uncover the mechanism by which STW alleviates POI through the regulation of internal reproductive organs (ovary-uterus axis).
MATERIALS AND METHODS: We combined chemical profiling (UHPLC-Q-Exactive-MS/MS) with network pharmacology to identify STW's active ingredients and targets. A POI model was established in mice using tripterygium glycosides (TG). Mice were treated with STW (1.2, 2.4, or 3.6 g/kg) or a hormone-based positive control consisting of sequential administration of estradiol (0.15 mg/kg) and progesterone (1.5 mg/kg). Serum hormone levels (E2, FSH, LH), estrous cycles, and ovarian and uterine pathology were assessed. Proteomic changes were analyzed using data-independent acquisition (DIA) mass spectrometry, and the key findings were validated through molecular docking, immunohistochemistry, TUNEL, and western blotting.
RESULTS: STW contains 72 active compounds with good oral bioavailability (OB > 28 %). Key ingredients like luteolin and kaempferol were predicted to interact with POI-related genes (e.g., ESR1/2, EGFR, AKT1). In TG-induced POI mice, STW improved general health, rebalanced hormones, normalized estrous cycles, and promoted both follicular development and endometrial repair. Proteomic analysis and molecular docking supported that STW targets the EGFR/PI3K/AKT pathway. In vivo validation confirmed that STW activated this pathway, reducing pro-apoptotic BAX and increasing anti-apoptotic BCL2 in both the ovaries and uteri.
CONCLUSIONS: The results indicate that STW effectively restores hormonal homeostasis, ovarian function, and uterine morphology in POI mice. This therapeutic effect may involve inhibition of the ovarian-endometrial cell apoptosis cascade via activation of the EGFR/PI3K/AKT pathway. These findings provide new insights into the molecular mechanisms of POI and support STW as a potential therapeutic strategy targeting the ovary-uterus axis.
