摘要
目的通过网络药理学和体外实验探讨瓜蒌-薤白药对(Gualou-Xiebai herb pair,GXHP)抗动脉粥样硬化(atherosclerosis,AS)的作用机制。方法利用TCMSP、DrugBank、GeneCards和Therapeutic Target等数据库筛选并收集GXHP的潜在成分、抗AS效应靶点;通过Cytoscape软件将药物靶点与疾病靶点进行网络化展示,通过网络拓扑算法筛选出关键靶基因;并通过STRING数据平台构建蛋白质-蛋白质相互作用(protein-protein interaction,PPI)网络;京都基因和基因组数据库(Kyoto encyclopedia of genes and genomes,KEGG)分析GXHP抗AS所涉及的核心通路。采用CCK-8法检测不同浓度GXHP对Raw264.7细胞的增殖抑制情况;以氧化型低密度脂蛋白(oxidized-low density lipoprotein,ox-LDL)处理Raw264.7细胞48 h,形成泡沫细胞;将细胞分为5组,分别为空白组(无处理)、模型组(80μg/mL ox-LDL处理)、GXHP低剂量组(80μg/mL ox-LDL+0.2 g/L GXHP)、GXHP中剂量组(80μg/mL ox-LDL+0.6 g/L GXHP)和GXHP高剂量组(80μg/mL ox-LDL+1.8 g/L GXHP);气相色谱质谱法(gas chromatography-mass spectrometry,GC-MS)和ELISA法分别检测各组总胆固醇(total cholesterol,TC)、游离胆固醇(free cholesterol,FC)以及炎症因子白细胞介素-6(interleukin-6,IL-6)和细胞间黏附分子-1(intercellular adhesion molecule-1,ICAM-1)的表达;Western blot法检测各组MAPK信号通路核心蛋白,包括磷酸化细胞外信号调节激酶(phosphorylated-extracellular signal-regulated kinases,p-ERK)、磷酸化p38丝裂原活化蛋白激酶(phosphorylated-p38 mitogen-activated protein kinase,p-p38MAPK)和磷酸化细胞核因子p65(phosphorylated-p65,p-p65)的表达。结果确定GXHP含有21种成分,包括槲皮素、亚麻酸乙酯、香叶木素等;21种成分分别对应154个作用靶点和36个核心靶点;KEGG分析发现核心靶点参与多种信号通路,包括脂质和AS、MAPK和PI3K-Akt等信号通路。体外实验结果显示,GXHP浓度在4 g/L时可显著抑制Raw264.7细胞的增殖(P<0.01),并选用1.8、0
Objective To investigate the mechanism of action of Gualou(Trichosanthis Fructus)-Xiebai(Allii Macrostemonis Bulbus)herb pair(GXHP)against atherosclerosis(AS)by network pharmacological analysis and in vitro experiments.Methods The databases of TCMSP,DrugBank,GeneCards,and Therapeutic Target were taken to screen and collect potential components and anti-AS disease targets of GXHP.Cytoscape was used to network display the drug targets and disease targets,and the key target genes were screened by network topology algorithm.The protein-protein interaction(PPI)network was constructed by STRING data platform.The Kyoto Encyclopedia of Genes and Genomes(KEGG)was taken to analyze the core pathways involved in the GXHP anti-AS.CCK-8 assay was applied to measure the proliferation inhibition of Raw264.7 cells treated with different concentrations of GXHP.Raw 264.7 cells were treated with oxidized-low density lipoprotein(ox-LDL)for 48 hours to form foam cells.The cells were assigned into five groups:blank control(no treatment),model(treat with 80μg/mL ox-LDL),and low-(80μg/mL ox-LDL and 0.2 g/L GXHP),medium-(80μg/mL ox-LDL and 0.6 g/L GXHP),and high-(80μg/mL ox-LDL and 1.8 g/L GXHP)dose GXHP groups.Gas chromatography-mass spectrometry(GC-MS)and ELISA were taken to measure the levels of total cholesterol(TC),free cholesterol(FC),and expressions of inflammatory factor interleukin-6(IL-6)and intercellular adhesion molecule-1(ICAM-1)in each group.Western blot was used to measure the expressions of core proteins of MAPK signaling pathway in each group,including phosphorylated-extracellular signal-regulated kinases(p-ERK),phosphorylated-p38 mitogen-activated protein kinase(p-p38MARK),and phosphorylated nuclear factor-κB p65(p-p65).Results It was determined that GXHP contained 21 components,including quercetin,ethyl linolenic acid,diosmetin,etc.The 21 components corresponded to 154 targets of action and 36 core targets,respectively.KEGG analysis showed that the core targets were involved in multiple signaling pathways,including
