Nonalcoholic fatty liver disease (NAFLD) is the most common metabolic liver disease globally, and the incidence of NAFLD has been increasing rapidly year by year. Currently, there is no effective pharmacotherapy for NAFLD. Therefore, studies are urgently needed to explore therapeutic drugs for NAFLD. In this study, we show that isoschaftoside (ISO) dramatically reduces lipid deposition in cells. Meanwhile, ISO treatment reverses the NAFLD and reduces hepatic steatosis in mice. Importantly, we reveal that ISO suppresses the expression of light-chain 3-II (LC3-II) and SQSTM1/p62 in palmitic acid (PA) induced autophagy inhibition in the cell model and the NAFLD mouse model, which suggests that ISO might reverse NAFLD through regulating autophagy flux. We propose that ISO might alleviate hepatic steatosis in NAFLD via regulating autophagy machinery. Consequently, our study suggests that ISO might be of potential clinical value in the field of NAFLD therapy. ISO might have the potential for future therapeutic application.
非酒精性脂肪性肝病(NAFLD)是全球最常见的代谢性肝病,且NAFLD的发病率逐年迅速上升。目前,尚无针对NAFLD的有效药物治疗方法。因此,迫切需要开展研究以探索用于NAFLD的治疗药物。在本研究中,我们发现异荭草苷(ISO)可显著减少细胞内脂质沉积。同时,ISO治疗可逆转NAFLD并减轻小鼠肝脏脂肪变性。重要的是,我们发现ISO在细胞模型和NAFLD小鼠模型中可抑制棕榈酸(PA)诱导的自噬抑制过程中轻链3-II(LC3-II)和SQSTM1/p62的表达,这表明ISO可能通过调节自噬通量来逆转NAFLD。我们提出,ISO可能通过调节自噬机制减轻NAFLD中的肝脏脂肪变性。因此,我们的研究表明ISO在NAFLD治疗领域可能具有潜在的临床价值。ISO可能具有未来治疗应用的潜力。
