    Abstract:
    ETHNOPHARMACOLOGICAL RELEVANCE: Diminished ovarian reserve (DOR) was considered a refractory reproductive endocrine condition that negatively affected female reproductivity. Yangjing Zhongyu Decoction (YJZYD) had effects on treating infertility. However, there were few studies on the mechanisms of YJZYD preserving ovarian reserve. AIM OF THE STUDY: To explore the possible mechanisms of YJZYD against DOR by UPLC-ESI-MS/MS, network pharmacology, and experimental validation. METHODS: The chemicals of YJZYD were measured by UPLC-ESI-MS/MS. The correlating targets of YJZYD and DOR were identified by the ETCM database, GeneCards database, and PubMed database. The common targets were employed with the DAVID database and visualized with the PPI network. GO and KEGG enrichment analyses were carried out to explore biological progression and pathways. In vivo experiments, energy production was assessed by ATP, and apoptosis rate was analyzed by TUNEL. The serum FSH, AMH, and E2 levels were evaluated by ELISA. Western blotting and immunohistochemistry were used to measure the expression of SIRT1, PGC1α, NRF1, COX IV, FSHR, CYP19A1, PI3K, p-Akt, Akt, Bcl-2, and Bax. RESULTS: 132 components in YJZYD were identified by UPLC-ESI-MS/MS. 149 overlapped targets were extracted from YJZYD and DOR, and the top 20 common targets included AKT1 and CYP19A1. ATP binding was involved in GO analysis. In the KEGG enrichment analysis, the metabolic pathway was the top, and the PI3K-Akt signaling pathway was included. In vivo experiments, YJZYD improved ovarian index and histomorphology. After YJZYD treatment, serum FSH, E2, and AMH were well-modulated, and the content of ATP was up-regulated. Besides, the expression of Bax was suppressed in ovarian tissue, while the expressions of SIRT1, PGC1α, NRF1, COX IV, FSHR, CYP19A1, PI3K, Bcl-2, and p-Akt/Akt were enhanced. CONCLUSION: YJZYD could attenuate reproductive endocrine disturbance and ovarian lesions in vivo by mediating steroidogenesis, energy metabolism, and cell apoptosis. This study uncovered the mechanisms of YJZYD against DOR, providing a theoretical basis for further study.
