| 中文摘要:目的 采用网络药理学和分子对接的方法分析苦参抗乳腺癌的主要活性成分及潜在分子机制。方法 采用TCMSP、ETCM数据库和查阅国内外文献收集筛选苦参化学成分，通过Swiss Target Prediction 数据库对有效活性成分的靶点进行预测，通过GeneCards、TTD、Drugbank、OMIM收集乳腺癌相关靶点，根据Venny 2.1.0软件筛选出苦参抗乳腺癌疾病靶点；采用Cytoscape软件构建苦参-核心活性成分-靶点网络图，用 STRING数据库分析共有靶点，构建PPI网络图，通过DAVID数据库和Hiplot平台对关键靶点蛋白进行GO功能富集分析和KEGG通路富集分析，并采用Schrodinger软件对活性成分与靶点进行分子对接，同时采用分子生物学方法对关键靶点进行验证。结果 从苦参中共筛选出结构明确的活性成分36个，筛选出70个苦参抗乳腺癌的疾病靶点，其中EGFR、AKT1、ESR1、SRC、CYP19A1、AR、ABCB1等12个核心靶点参与乳腺癌中内分泌抵抗、EGFR酪氨酸激酶抑制剂耐药、雌激素等信号通路，且核心成分与关键靶点AR之间的结合能最高。体外细胞实验显示，苦参提取物可抑制乳腺癌细胞的增殖，诱导细胞凋亡，上调AR蛋白的表达。结论 苦参通过多成分作用于多靶点和多个信号通路，调节复杂的生物过程发挥抗乳腺癌的作用，苦参对AR蛋白的上调可能成为治疗乳腺癌新的治疗策略。 |

| Abstract:Objective To analyze the main active components and potential molecular mechanism of Sophora flavescens against breast cancer based on network pharmacology and molecular docking. Methods The chemical constituents were collected and screened by TCMSP, ETCM database and literature review. The targets of active ingredients were predicted by Swiss Target Prediction database. Breast cancer-related targets were collected by GeneCards, TTD, Drugbank and OMIM. The anti-breast cancer targets of Sophora flavescens were screened by Venny 2.1.0 software. Cytoscape software was used to construct the network diagram of Sophora flavescens-key active ingredients-targets. STRING database was used to analyze the common targets, and PPI network diagram was constructed. GO function enrichment analysis and KEGG pathway enrichment analysis of key target proteins were performed by DAVID database and Hiplot online platform. Schrodinger software was used to calculate the molecular docking between the active ingredients and targets. Molecular biological methods were used to verify the key targets. Results A total of 36 active components with clear structures were screened from Sophora flavescens. 70 anti-breast cancer targets of Sophora flavescens were screened out. 12 core targets including EGFR, AKT1, ESR1, SRC, CYP19A1, AR and ABCB1 participate in endocrine resistance, EGFR tyrosine kinase inhibitors and estrogen signaling pathways in breast cancer. Moreover, the docking score between the core component and the key target AR is the highest. In vitro experiments showed that the extract of Sophora flavescens can inhibit the proliferation of breast cancer cells, induce cell apoptosis and up-regulate AR protein expression. Conclusion It was revealed that Sophora flavescens plays an anti-breast cancer role by regulating complex biological processes through multiple components acting on multiple targets and signaling pathways. The upregulation of AR protein by Sophora flavescens may become a new therapeutic strategy for the treatment of breast cancer. |
