Non-alcoholic fatty liver disease (NAFLD) is a common liver disorder characterized by hepatic steatosis, inflammation and fibrosis. Ganfule (GFL), a traditional Chinese medicine, has demonstrated therapeutic potential in the treatment of NAFLD but the mechanisms involved are not fully understood.To evaluate the biochemical mechanisms of GFL in treating NAFLD by examining its effects on biological networks, key therapeutic targets, histopathological changes and clinical implications.
Chemical component screening, key target prediction, biological functional enrichment analysis, lipid profile localization analysis and complex network analysis were performed on GFL using multi-database mining, network analysis and molecular docking. An NAFLD rat model was then established and treated with different doses of GFL. Histopathological evaluation and western blotting were used to verify the expression levels of key target proteins in GFL-treated NAFLD rats.
Network analysis analysis identified 12 core targets, 12 core active ingredients and 7 core Chinese medicinal herbs in GFL potentially involved in the treatment of NAFLD. Biological functional enrichment analysis revealed the involvement of lipid metabolism, apoptosis and intracellular signaling pathways. Molecular docking confirmed a strong affinity between GFL's core compounds and certain target proteins. Histopathological examination of an NAFLD rat model showed reduced hepatocellular steatosis after GFL treatment. Western blotting revealed significant downregulation of PPARA and PPARD protein expression and upregulation of PIK3CG and PRKACA protein expression in NAFLD rats treated with lower doses of GFL.
Our results suggest that GFL modulates key proteins involved in lipid metabolism and apoptosis pathways. GFL improved the histopathological features of NAFLD rats by regulating lipid metabolism as well as reducing hepatocyte apoptosis and hepatocellular steatosis. These findings offer insights into the biochemical mechanism of action of GFL and support its use in the treatment for NAFLD.
非酒精性脂肪性肝病(NAFLD)是一种常见的肝脏疾病,其特征为肝脂肪变性、炎症和纤维化。中药肝复乐(GFL)已显示出治疗NAFLD的潜在疗效,但其涉及的机制尚未完全明确。通过研究其对生物网络、关键治疗靶点、组织病理学变化及临床意义的影响,评估GFL治疗NAFLD的生化机制。
利用多数据库挖掘、网络分析和分子对接技术,对GFL进行化学成分筛选、关键靶点预测、生物功能富集分析、脂质谱定位分析和复杂网络分析。随后建立NAFLD大鼠模型,并用不同剂量的GFL进行治疗。采用组织病理学评估和蛋白质免疫印迹法验证GFL治疗的NAFLD大鼠中关键靶点蛋白的表达水平。
网络分析确定了GFL中可能参与NAFLD治疗的12个核心靶点、12种核心活性成分和7种核心中药材。生物功能富集分析揭示了脂质代谢、细胞凋亡和细胞内信号通路的参与。分子对接证实了GFL的核心化合物与某些靶蛋白之间具有很强的亲和力。对NAFLD大鼠模型的组织病理学检查显示,GFL治疗后肝细胞脂肪变性减轻。蛋白质免疫印迹法显示,低剂量GFL治疗的NAFLD大鼠中PPARA和PPARD蛋白表达显著下调,PIK3CG和PRKACA蛋白表达上调。
我们的结果表明,GFL调节参与脂质代谢和细胞凋亡途径的关键蛋白。GFL通过调节脂质代谢以及减少肝细胞凋亡和肝细胞脂肪变性,改善了NAFLD大鼠的组织病理学特征。这些发现为GFL的生化作用机制提供了见解,并支持其用于NAFLD的治疗。
