摘要
该文运用网络药理学和分子对接的方法,研究补肾促卵方治疗多囊卵巢综合征(polycystic ovary syndrome, PCOS)导致不孕的作用机制。首先,通过TCMSP数据库获取补肾促卵方活性成分和药物潜在靶点;应用GeneCards数据库检索PCOS导致不孕的疾病靶点。将药物靶点与疾病靶点经过Uniprot数据库校正后取交集基因。结合STRING数据库和Cytoscape 3.7.2对交集基因进行PPI分析。应用Cytoscape 3.7.2的ClueGO插件对交集基因进行GO富集分析及KEGG信号通路富集分析。最后运用AutoDockVina和MGLtools软件对补肾促卵方关键活性成分与作用靶点进行分子对接验证。结果在补肾促卵方中共获得136个药物活性成分,314个药物靶点,GeneCards数据库获得136个疾病靶点,49个药物与疾病交集基因;GO富集发现,主要涉及肌肉细胞凋亡过程的调节、小分子代谢过程的正调控、核心启动子结合、RNA聚合酶Ⅱ对pri-miRNA转录的调控、跨膜运输的负调控等生物功能;经过KEGG通路富集分析,其主要涉及MAPK、PI3K-Akt、p53、HIF-1等信号通路。分子对接结果显示槲皮素(quercetin)和PTGS2能稳定的结合并通过氨基酸残基THR206、TRP387、ASN382等发生相互作用。该研究初步揭示了补肾促卵方治疗PCOS导致不孕的多成分、多靶点、多途径作用机制,为进一步研究提供依据。
This study used network pharmacology and molecular docking to study the mechanism of Bushen Culuan Formula in the treatment of infertility caused by polycystic ovary syndrome(PCOS). The active ingredients and potential drug targets of Bushen Cu-luan Decoction were obtained by searching the Traditional Chinese Medicine System Pharmacology(TCMSP) database, and the targets of PCOS by searching GeneCards. After the drug targets and disease targets were corrected by Uniprot, the intersection genes were obtained. STRING database and Cytoscape 3.7.2 were used for protein-protein interaction(PPI) analysis of the intersection genes. The ClueGO plug-in of Cytoscape 3.7.2 was employed to perform gene ontology(GO) enrichment and KEGG pathway enrichment for the intersection genes. Finally, molecular docking of the key active ingredients with the targets of Bushen Culuan Formula was performed using AutoDockVina and MGLtools. A total of 136 active ingredients and 314 drug targets of the decoction were obtained from TCMSP, and 136 disease targets from GeneCards. Finally, 49 drug-disease intersection genes were obtained. GO enrichment found that the genes were mainly involved in the regulation of muscle cell apoptosis, positive regulation of small molecule metabolism, core promoter binding, RNA polymerase Ⅱ regulation of pri-miRNA transcription, negative regulation of transmembrane transport and other biological functions. The enriched KEGG pathways mainly included MAPK, PI3 K-Akt, p53, and HIF-1 signaling pathways. The results of molecular docking showed that quercetin and PTGS2 can bind stably and interact through amino acid residues THR206, TRP387, ASN382, etc. This study preliminarily reveals the multi-component, multi-target, and multi-pathway mechanism of Bushen Culuan Formula in the treatment of PCOS-related infertility, which provides a basis for further research.
