    摘要:

    目的:运用网络药理学和分子对接技术探讨胁腹宁颗粒治疗代谢相关脂肪性肝病(MAFLD) 的活 性成分、作用靶点及分子机制。方法:运用中药系统药理学数据库与分析平台(TCMSP)、Pubchem、SEA、 Swiss Target Prediction、STITCH等数据库筛选胁腹宁颗粒活性成分、预测靶点;利用GEO数据库并使用R语言 limma 包分析MAFLD 差异基因; 运用CTD、Genecards、OMIM 数据库筛选MAFLD 疾病靶点, 采用 Cytoscape3.7.2软件构建化合物-靶点-疾病网络和靶点蛋白质互作(PPI) 网络;通过DAVID数据库进行基因本 体(GO) 功能富集分析和京都基因与基因组百科全书(KEGG) 通路富集分析;利用AutoDock Vina软件进行 胁腹宁颗粒与核心靶点蛋白的分子对接模拟验证,最后利用PyMol软件对分子对接模式进行可视化。结果:共 筛选得到胁腹宁颗粒的活性成分199个,靶点451个,胁腹宁颗粒活性成分与MAFLD交集靶点177个。PPI网 络的拓扑学分析共筛选出29个关键靶点。GO富集分析中有587个显著富集,其中生物过程(BP) 295个,细 胞组分(CC) 420个,分子功能(MF) 107个。主要涉及细胞对胰岛素刺激的反应、葡萄糖输入正调控、胰岛 素受体信号通路、细胞因子活性、炎症反应等。KEGG通路显著富集85条,主要包括代谢相关通路、免疫炎症 相关通路、细胞增殖与凋亡相关信号通路。分子对接结果显示延胡索乙素、大黄素、芒柄花素、芦丁这4个活 性成分与甘油醛-3-磷酸脱氢酶(GADPH)、白细胞介素-6(IL-6)、前列腺素内过氧化物合酶2(PTGS2)、肿 瘤坏死因子(TNF) 紧密结合。结论:网络药理学研究结合分子对接技术证实胁腹宁颗粒可通过代谢相关通 路、免疫炎症相关通路、氧化应激与脂质过氧化相关信号通路多成分、多靶点、多途径治疗MAFLD。

    Abstract:

    Abstract: Objective: To investigate the active components, potential targets, and molecular mechanisms of Xiefuning Granules in treating metabolic-associated fatty liver disease (MAFLD) using network pharmacology and molecular docking technology. Methods: The Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP),PubChem,SEA,Swiss Target Prediction,and STITCH databases were used to screen active components and predict targets of Xiefuning Granules. The GEO database and R language limma package were employed to analyze MAFLD differential genes. The Comparative Toxicogenomics Database (CTD),GeneCards,and OMIM databases were used to screen MAFLD disease targets. Cytoscape 3.7.2 software was utilized to construct compound-target-disease networks and protein-protein interaction (PPI) networks. Gene Ontology (GO) functional enrichment analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis were performed using the DAVID database. Molecular docking simulations between Xiefuning Granules and core target proteins were conducted using AutoDock Vina software, and the docking patterns were visualized using PyMOL software. Results : A total of 199 active components and 451 targets of Xiefuning Granules were screened, with 177 overlapping targets between the active components and MAFLD. Topological analysis of the PPI network identified 29 key targets. GO enrichment analysis revealed 587 significant enrichments,including 295 biological processes (BP), 420 cellular components (CC), and 107 molecular functions (MF), primarily involving cellular response to insulin stimulus, positive regulation of glucose import, insulin receptor signaling pathway, cytokine activity, and inflammatory response. KEGG pathway analysis showed 85 significantly enriched pathways, mainly including metabolism-related pathways, immune-inflammatory-related pathways, and cell proliferation and apoptosis-related signaling pathways. Molecular docking results demonstrated that four active components (tetrahydropalmatine,emodin, formononetin,and rutin) could form stable conformations with glyceraldehyde-3-phosphate dehydrogenase( GAPDH), interleukin-6 (IL-6), prostaglandin-endoperoxide synthase 2 (PTGS2), and tumor necrosis factor (TNF). Conclusion: Network pharmacology combined with molecular docking technology confirmed that Xiefuning Granules can treat MAFLD through multiple components, targets, and pathways, including metabolism-related pathways, immune-inflammatory-related pathways,and oxidative stress and lipid peroxidation-related signaling pathways.
