The occurrence of fatty liver disease, resulting from the accumulation of excessive fat within the liver, has been showing a significant and rapid increase. This study aimed to evaluate the therapeutic effects of Cheong-sang-bang-pung-san extract (CB) on fatty liver disease, and to elucidate the underlying mechanisms. We used a high-fat diet (HFD)-fed fatty liver mice and free fatty acid (FFA) induced HepG2 cell lipid accumulation model. The levels of serum, hepatic, and intracellular lipid content were assessed. Histopathological staining was used to evaluate the extent of hepatic lipid accumulation. Real-time polymerase chain reaction and Western blotting were conducted to examine the expression of factors associated with lipid metabolism. We demonstrated that treatment with CB dramatically reduced body weight, liver weight, and fat mass, and improved the serum and hepatic lipid profiles in HFD-induced fatty liver mice. Additionally, CB alleviated lipid accumulation in HFD-fed mice by controlling lipid metabolism, including fatty acid uptake, triglyceride and cholesterol synthesis, and fatty acid oxidation, at the mRNA as well as protein levels. In free fatty acid-treated HepG2 cells, CB significantly reduced intracellular lipid accumulation by regulating lipid metabolism via the activation of AMP-activated protein kinase. These findings provide insights into the mechanisms underlying CB's effects on liver steatosis and position of CB as a potential therapeutic candidate for managing lipid metabolic disorders.
脂肪肝疾病的发生是由于肝脏内脂肪过度堆积所致,且一直呈现出显著且快速的增长态势。本研究旨在评估清上防风散提取物(CB)对脂肪肝疾病的治疗效果,并阐明其潜在机制。我们使用了高脂饮食(HFD)喂养的脂肪肝小鼠和游离脂肪酸(FFA)诱导的HepG2细胞脂质积累模型。评估了血清、肝脏和细胞内脂质含量水平。采用组织病理学染色来评估肝脏脂质积累的程度。进行实时聚合酶链反应和蛋白质免疫印迹法以检测与脂质代谢相关因子的表达。我们证明,CB治疗显著降低了HFD诱导的脂肪肝小鼠的体重、肝脏重量和脂肪量,并改善了血清和肝脏脂质谱。此外,CB通过在mRNA和蛋白质水平上控制脂质代谢,包括脂肪酸摄取、甘油三酯和胆固醇合成以及脂肪酸氧化,减轻了HFD喂养小鼠的脂质积累。在游离脂肪酸处理的HepG2细胞中,CB通过激活AMP激活的蛋白激酶调节脂质代谢,显著减少了细胞内脂质积累。这些发现为CB对肝脂肪变性作用的潜在机制提供了见解,并确立了CB作为治疗脂质代谢紊乱潜在候选药物的地位。
