摘要: 运用网络药理学方法探究逍遥丸(Xiaoyao Wan,XYW)治疗肝硬化的潜在作用机制,并进行实验验证。基于ETCM数据库、多种人类疾病数据库查找逍遥丸及肝硬化相关基因靶点,应用String、ToppGene平台及Cytoscape软件等工具分别构建蛋白质互作(PPI)网络、中药-化学成分-作用靶基因网络以及中药-肝硬化相关通路网络。通过网络拓扑结构筛选出逍遥丸治疗肝硬化的核心作用靶基因、关键化学成分,并基于药物作用的通路探讨药效机制。在体外实验中,用逍遥丸关键成分干预肝纤维化细胞系Lx-2后,采用RT-PCR法检测关键基因的表达情况。通过ETCM数据库得到逍遥丸中化学成分505个,作用靶基因848个。通过5个人类疾病相关数据库中检索肝硬化相关基因,合并去冗余后共得到622个肝硬化基因。将848个逍遥丸作用靶基因与164个肝硬化基因取交集后,得到30个重合基因。对互作网络分析后筛选出核心基因节点有9个,为ALB、INS、IL1B、IL6、TNF、PPARG、TLR4、ARG1和GPT。构建中药-化学成分-肝硬化基因网络,并利用Cytoscape软件进行可视化,得到关键化学成分为槲皮素、柴胡皂苷、芹黄素、山柰素等。体外实验证实Lx-2的生长与柴胡皂苷、槲皮素呈剂量依赖性关系,且TNF、TL1B、IL-6、PPARG、TLR4、Collagen、TGFB1、α-SMA的表达均降低。通过网络药理学分析和实验验证得出逍遥丸通过多作用靶基因、多通路来发挥治疗肝硬化的作用。

Abstract:

This study investigates the potential mechanisms of Xiaoyao Wan (XYW) in treating liver cirrhosis using network pharmacology and experimental methods.Gene targets related to XYW and liver cirrhosis were identified from the ETCM database and various human disease databases.Using tools like STRING, ToppGene, and Cytoscape, networks of protein interactions, Chinese herbs-chemical components-target genes, and Chinese herbs-liver cirrhosis pathways were constructed.Key target genes and chemical components were identified.In vitro experiments with the Lx-2 liver fibrosis cell line, treated with key XYW components, showed that the expression of crucial genes was affected.The study found 505 chemical components and 848 target genes associated with XYW.After intersecting with 622 liver cirrhosis genes, 30 overlapping genes were identified.Core genes included ALB, INS, IL1B, IL6, TNF, PPARG, TLR4, ARG1, and GPT.Key chemical components identified were quercetin, saikosaponin, apigenin, and kaempferol.In vitro, saikosaponin and quercetin showed a dose-dependent effect on Lx-2 cells and reduced expression of TNF, IL1B, IL-6, PPARG, TLR4, collagen, TGFB1, and α-SMA.The findings suggest that XYW treats liver cirrhosis through multiple targets and pathways.
