Cheong-sang-gyeon-tong-tang improves hepatic steatosis by regulating cholesterol metabolism.

Background: Hepatic steatosis is characterized by lipid accumulation in hepatocytes. Cheong-sang-gyeon-tong-tang is a major prescription for all types of headaches in traditional East Asian medicine. Objective: This study aimed to investigate the pharmacological effects of Cheong-sang-gyeon-tong-tang extract (CG) on high-fat diet (HFD)-induced hepatic steatosis in mice and to explore the underlying mechanism. Results: Treatment with CG significantly reduced body weight, liver weight, and epididymal fat mass, as well as improved the serum and hepatic lipid profiles in the HFD-induced fatty liver mouse model. Further, CG alleviated lipid accumulation in HFD-fed mice by controlling lipid metabolism, including triglyceride and cholesterol synthesis, and fatty acid oxidation at the mRNA level. CG also regulated the expression of cholesterol regulatory proteins in HFD-induced fatty liver mice. Conclusions: These results indicate that CG alleviates hepatic steatosis by regulating cholesterol homeostasis in HFD-induced fatty liver mice, thus improving our understanding of the mechanisms by which CG improves hepatic steatosis. Therefore, we propose CG as a therapeutic candidate for lipid metabolic disorders such as fatty liver disease. [ABSTRACT FROM AUTHOR]
