摘要:

目的 基于网络药理学和体外实验分析验证茵陈蒿汤(YCHD)治疗肝纤维化(HF)的核心功能成分群(CFCG)以及潜在通路。 方法 在DisGeNET、Genecards、CMGRN和PTHGRN提取了HF的PPI数据,使用Cytoscape 3.9.1构建权重网络。从TCMSP中收集茵陈蒿汤所有化学成分,用PreADMET Web服务器和SwissTargetPrediction选择茵陈蒿汤潜在活性成分和靶点。构建融合模型获取功能效应空间并评估有效蛋白,得到CFCG,再进一步对所有目标进行GO和KEGG通路富集分析。细胞实验:体外培养人肝星状细胞(LX-2),分别设置空白组(不加TGF-β1刺激)、对照组NC(20 ng/mL TGF-β1刺激)和化合物组(0、50、100、200 μmol/L),CCK-8实验检测药物敏感性,qPCR实验检测化合物对LX-2中Ⅰ型胶原Α1(COL1A1)的影响,Western blotting实验分析评估化合物在TGF-β1刺激下对LX-2中潜在通路的影响,验证潜在治疗机制。 结果 分析得到1005个致病基因,茵陈蒿汤潜在活性成分和靶点分别有226个和1529个,核心功能成分群有52个。根据模型计算结果,选取得分最高的乙酸苄酯、香草酸、苯甲酸甲酯、虎杖苷、月桂酸、阿魏酸进行CCK-8验证发现在200 μmol/L内无细胞毒性;在qPCR实验中,与TGF-β1组相比苯甲酸甲酯、虎杖苷、月桂酸和阿魏酸能够抑制TGF-β1诱导的LX-2活化。GO和KEGG分析及Western blotting验证发现,这4种成分在200 μmol/L浓度时对PI3K、p-PI3K、AKT、p-AKT、ERK、p-ERK、P38 MAPK、p-P38 MAPK有不同程度的抑制。 结论 茵陈蒿汤抗肝纤维化可能是其中的乙酸苄酯、香草酸、苯甲酸甲酯、虎杖苷、月桂酸、阿魏酸等成分通过抑制PI3K-AKT和MAPK通路实现的。

Abstract:

Objective To analyze the core functional component groups (CFCG) in Yinchenhao Decoction (YCHD) and their possible pathways for treating hepatic fibrosis based on network pharmacology. Methods PPI data were extracted from DisGeNET, Genecards, CMGRN and PTHGRN to construct a weighted network using Cytoscape 3.9.1. The data of the chemical components in YCHD were obtained from Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP), and the potential active components and targets were selected using PreADMET Web server and SwissTargetPrediction. A fusion model was constructed to obtain the functional effect space and evaluate the effective proteins to identify the CFCG followed by GO and KEGG pathway enrichment analyses for all the targets. In cultured human hepatic stellate cells (LX-2 cells), the cytotoxicity of different compounds in YCHD was tested using CCK-8 assay; the effects of these compounds on collagen α1 (Col1a1) mRNA expression and the pathways in 20 ng/mL TGF-β1-stimulated cells were analyzed using RT-qPCR and Western blotting. Results A total of 1005 pathogenic genes, 226 potential active components and 1529 potential targets in YCHD and 52 potential targets of CFCG were obtained. Benzyl acetate, vanillic acid, clorius, polydatin, lauric acid and ferulic acid were selected for CCK-8 verification, and they all showed minimal cytotoxicity below the concentration of 200 μmol/L. Clorius, polydatin, lauric acid and ferulic acid all effectively inhibited TGF-β1-induced LX-2 cell activation. At the concentration of 200 μmol/L, all these 4 components inhibited PI3K, p-PI3K, AKT, p-AKT, ERK, p-ERK, P38 MAPK and p-P38 MAPK expressions in TGF-β1-induced LX-2 cells. Conclusion The therapeutic effect of YCHD on hepatic fibrosis is probably mediated by its core functional components including benzyl acetate, vanillic acid, clorius, polydatin, lauric acid and ferulic acid, which inhibit the PI3K-AKT and MAPK pathways in hepatic stellate cells.
