摘要:

目的:阐明红花总黄酮药效和网络药理学机制,探讨其关键靶点和相关通路,明确其抗肝纤维化的作用机制。方法:对红花总黄酮进行LC-MS/MS测定及成分分析;通过TCMSP数据库、SWISS ADME数据库及文献查询筛选出有效成分;在Swiss Target Prediction数据库筛选出红花总黄酮相关靶点;在GeneCards 数据库筛选出肝纤维化相关靶点;通过Venny.2.1.0取交集获得红花总黄酮抗肝纤维化靶点;通过STRING数据库进行蛋白互作分析;通过Cytoscape软件进行可视化分析;在Metascape平台进行基因本体(GO)功能和京都基因与基因组百科全书(KEGG)通路分析;运用AutoDock软件对核心靶点和活性成分进行分子对接验证;通过动物模型实验和离体细胞实验验证红花总黄酮抗肝纤维化的作用机制。结果:共鉴定出红花黄酮类成分41个。通过网络药理学分析,获得红花总黄酮抗肝纤维化靶点149个,其中核心靶点23个。GO富集分析共涉及生物过程(BP)、细胞组分(CC)、分子功能(MF)三个方面。KEGG富集结果显示,PI3K/Akt、MAPK等是参与肝纤维化发生发展的通路。通过分子对接验证了活性成分Quercetin、Acacetin、Glabridin分别与Akt1、HIFIA紧密结合。在动物模型实验中,通过HE和Masson染色观察到红花总黄酮给药组纤维增生减少,胶原沉积减少,炎性细胞浸润减少,纤维化的肝脏组织得到改善;Western blotting结果提示,红花总黄酮可以使肝纤维化标志因子α-SMA、Collagen I(P<0.01)和PI3K/Akt信号通路标志蛋白P-PI3K、PI3K、P-Akt、Akt表达量下降(P<0.01);在离体细胞实验中:Western blotting结果提示,红花总黄酮可以使肝纤维化标志因子α-SMA、Collagen I(P<0.01)和PI3K/Akt信号通路标志蛋白P-PI3K、PI3K、P-Akt、Akt表达量下降(P<0.01)。结论:红花总黄酮通过多成分、多靶点、多通路的形式发挥抗肝纤维化的作用,其作用机制可能是通过调控PI3K/Akt信号通路实现的。

Abstract:

AIM: To elucidate the pharmacodynamic and network pharmacological mechanisms of total flavonoids of Carthamus tinctorius L., to explore their key targets and related pathways, and to clarify their mechanism of action against hepatic fibrosis. METHODS: The total flavonoids of Carthamus tinctorius L. were determined by LC-MS/MS and analysed for their compositions; the active ingredients were screened by TCMSP database, SWISS ADME database and literature search; the targets related to total flavonoids of Carthamus tinctorius L. were screened by Swiss Target Prediction database; and the targets related to hepatic fibrosis were screened by GeneCards database; the anti-hepatic fibrosis targets of total flavonoids of Carthamus tinctorius L. were obtained by taking the intersection of Venny.2.1.0; the protein interactions were analysed by STRING database; the visualization analysis was carried out by Cytoscape software; the GO function and KEGG pathway analysis was carried out by Metascape platform; and molecular docking was verified by using AutoDock software for the core targets and active ingredients. The mechanism of anti-hepatic fibrosis of total flavonoids of Carthamus tinctorius L. was verified by animal model and in vitro cell experiments. RESULTS: A total of 41 flavonoid components were identified in Carthamus tinctorius L. Through the network pharmacological analysis, 149 anti-hepatic fibrosis targets of total flavonoids of Carthamus tinctorius L. were obtained, including 23 core targets.The GO enrichment analyses involved a total of three aspects, namely, biological process (BP), cellular component (CC), and molecular function (MF). KEGG enrichment results showed that PI3K/Akt and MAPK are pathways involved in the development of hepatic fibrosis. Molecular docking verified that the active ingredients Quercetin, Acacetin and Glabridin were tightly bound to Akt1 and HIFIA, respectively. In animal model experiments, it was observed by HE and Masson staining that fibroplasia was reduced, collagen deposition was reduced, inflammatory cell infiltration was reduced, and fibrotic liver tissues were improved in total flavonoids of Carthamus tinctorius L. administration group. In isolated cell experiments: Western blotting results suggested that total flavonoids of Carthamus tinctorius L. could decrease the hepatic fibrosis marker factor α-SMA, Collagen1 (P<0.01) and PI3K, Akt protein expression (P<0.01). CONCLUSION: Total flavonoids of Carthamus tinctorius L. exerted anti-hepatic fibrosis effects through multi-components, multi-targets and multi-pathways, and their mechanism of action may be achieved by regulating the PI3K/Akt signalling pathway.
