The Network Pharmacology Analysis of Tonifying Yang Formula for the Treatment of Diminished Ovarian Reserve.

Background: Diminished ovarian reserve (DOR) can lead to amenorrhea, infertility, and even the development of premature ovarian insufficiency, severely affecting the quality of life for women. Therefore, it is important to determine the main components of Tonifying Yang Formula, analyze the active substances and effective targets for treating DOR using Tonifying Yang Formula, and explore its potential mechanisms of action.

Objective: The study is aim to determine the main components of Tonifying Yang Formula, analyze the active substances and effective targets for treating DOR using Tonifying Yang Formula, and explore its potential molecular mechanisms of action, providing important theoretical basis for clinical application.

Methods: The main active components of Tonifying Yang Formula and their potential therapeutic targets for DOR were searched using the Chinese Medicine Systems Pharmacology Database and Analysis Platform, BATMAN-TCM, GeneCards, OMIM, and Uniprot databases. The protein-protein interaction network of shared targets between drugs and diseases was constructed using the STRING database. The shared targets of drugs and diseases were subjected to GO analysis and KEGG pathway enrichment analysis using the DAVID database. AutoDock Vina was used to perform molecular docking between the active substances and key targets of the drug to validate their interaction activities.

Results: The key chemical components in the Tonifying Yang Formula for DOR treatment include quercetin, luteolin, beta-sitosterol, stigmasterol, and kaempferol. The 164 key targets for treating DOR with Tonifying Yang Formula included AKT1, TNF, JUN, TP53, IL6, IL1B, EGFR, VEGFA, INS, and CASP3, among others. GO enrichment analysis revealed that the Tonifying Yang Formula mainly regulates gene expression positively, negatively regulates the apoptotic process, and affects signal transduction. KEGG pathway enrichment analysis showed that Tonifying Yang Formula is mainly involved in cancer-related pathways, the AGE-RAGE signaling pathway in diabetic complications, prostate cancer, lipid and atherosclerosis, fluid shear stress and atherosclerosis, and the IL-17 signaling pathway. Molecular docking results indicated that the core components of the Tonifying Yang Formula had higher docking energies and stable binding with targets such as AKT1, IL6, JUN, TNF, and TP53. This study selected the PI3K/AKT signaling pathway for validation. Through experimental research, we found that Tonifying Yang Formula could improve ovarian reserve function by activating the PI3K/AKT signaling pathway.

Conclusions: The potential mechanism of Tonifying Yang Formula therapy for DOR may be related to the influence of Chinese herbal compounds on pathways such as AKT1, IL6, JUN, TNF, and TP53, regulating the proliferation and apoptosis of ovarian granulosa cells, maintaining the function of the ovarian corpus luteum, regulating the secretion of related hormones, and alleviating ovarian tissue inflammation.
