摘要:


文题释义:
网络药理学:是基于系统生物学的原理阐释疾病发展的过程,研究药物、疾病和靶点之间的协同关系,预测疾病治疗作用靶点和信号通路。
斑马鱼非酒精性脂肪肝模型:斑马鱼具有体型小、养殖成本低、发育迅速、产卵量大、基因组与人类同源性高等特点,受精后5 d斑马鱼的消化系统发育成熟,且幼鱼胚胎透明,可直接观察内脏,可以克服哺乳动物耗时长、用药量大、实验强度大以及细胞模型条件要求严苛、作用环节单一等缺陷。应用蛋黄粉溶液浸泡诱导非酒精性脂肪肝斑马鱼模型,能使幼鱼肝脏出现明显病理损伤。

背景:苦参总黄酮具有抗炎、调节免疫、抗氧化、抗肝损伤等多种药理作用,其对非酒精性脂肪肝的治疗效果和作用机制尚不明确。
目的:利用生物信息学、网络药理学方法及斑马鱼实验验证苦参总黄酮治疗非酒精性脂肪肝的作用机制。
方法:构建非酒精性脂肪肝斑马鱼模型,观察苦参总黄酮治疗后斑马鱼肝脏脂质累积情况、病理形态改变,以及脂质累积、炎症基因的表达变化。通过TCMSP、Swiss Target Prediction、Bat-man数据库获取苦参总黄酮活性成分与非酒精性脂肪肝相关靶点;利用STRING数据库进行蛋白互作网络分析,GO功能富集和KEGG通路富集分析。基于GSE33814数据集,筛选出“苦参总黄酮-非酒精性脂肪肝”交集靶点的差异表达基因并运用R4.3.2软件进行相关性分析、受试者操作特征曲线分析,通过验证集GSE89632验证核心基因;RT-qPCR和Western blot实验验证核心通路相关基因和蛋白表达。
结果与结论:①苦参总黄酮能够改善非酒精性脂肪肝斑马鱼肝脏脂质累积,显著抑制斑马鱼脂质和转氨酶水平的升高(P < 0.05);调节炎症和脂代谢相关基因的表达;②网络药理学中获得168个共同靶点,cytoscape拓扑分析综合筛选出排名前10的核心基因分别为HSP90AA1、STAT3、PIK3R1、MAPK1、AKT1、RXRA、PIK3CA、EGFR、JAK2、ESR1;GO和KEGG分析通路主要集中在胰岛素抵抗、脂质与动脉粥样硬化方面;生物信息分析共获得59个“苦参总黄酮-非酒精性脂肪肝” 差异表达基因,受试者操作特征曲线分析及验证集验证得到6个核心靶点在健康人与非酒精性脂肪肝患者间有显著差异(P < 0.01);③RT-qPCR和Western blot实验结果表明苦参总黄酮能够抑制非酒精性脂肪肝斑马鱼JAK2/STAT3信号通路的激活。以上结果表明,苦参总黄酮通过调节JAK2/STAT3信号通路减轻炎性反应,抑制脂质累积从而改善非酒精性脂肪肝。

Abstract: BACKGROUND: Total flavonoids from Sophora flavescens have a variety of pharmacological effects, including anti-inflammatory, immunomodulatory, antioxidant, and anti-hepatic injury, but the therapeutic effects and mechanisms in non-alcoholic fatty liver disease are not clear. 
OBJECTIVE: To reveal the mechanism of total flavonoids from Sophora flavescens in the treatment of non-alcoholic fatty liver disease using bioinformatics, network pharmacology and zebrafish experimental validation. 
METHODS: A zebrafish model of non-alcoholic fatty liver disease was constructed to observe lipid accumulation, pathomorphologic changes, and expression of inflammatory genes in the liver of zebrafish after treatment with total flavonoids from Sophora flavescens. The active ingredients of total flavonoids from Sophora flavescens and non-alcoholic fatty liver disease-related targets were obtained from TCMSP, Swiss Target Prediction, and Bat-man databases. STRING was used to perform protein-protein interaction network analysis, GO functional enrichment and KEGG pathway enrichment analysis. Based on the GSE33814 dataset, the differentially expressed genes of total flavonoids from Sophora flavescens and non-alcoholic fatty liver disease intersection targets were screened out. Correlation analysis and receiver operating characteristic curve were performed using R4.3.2 software. Core genes were verified by the validation set GSE89632. RT-qPCR and western blot assays were performed to verify the expression of core pathway-related genes and proteins.
RESULTS AND CONCLUSION: (1) Total flavonoids from Sophora flavescens could improve lipid accumulation in the liver of zebrafish with non-alcoholic fatty liver disease, significantly inhibited the elevation of lipid and aminotransferase levels in zebrafish (P < 0.05), and regulated the expression of genes related to inflammation and lipid metabolism. (2) A total of 168 common targets were obtained using the network pharmacology, and top 10 core genes, identified by cytoscape topology analysis, were HSP90AA1, STAT3, PIK3R1, MAPK1, AKT1, RXRA, PIK3CA, EGFR, JAK2, and ESR1. GO and KEGG analysis pathways mainly included insulin resistance, lipids, and atherosclerosis. There were a total of 59 differentially expressed genes after intersection of total flavonoids from Sophora flavescens and non-alcoholic fatty liver disease targets. The receiver operating characteristic curve and validation set analyses yielded six core targets that were significantly different between healthy individuals and patients with non-alcoholic fatty liver disease (P < 0.01). (3) RT-PCR and western blot results verified that total flavonoids from Sophora flavescens inhibited the activation of the JAK2/STAT3 signaling pathway in zebrafish. To conclude, total flavonoids from Sophora flavescens may alleviate the inflammatory response through the JAK2/STAT3 signaling pathway, thus inhibiting lipid accumulation and improving non-alcoholic fatty liver disease.
