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

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.

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.

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.

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.
