This invention relates to the application of
secretin in the preparation of drugs for treating
steatohepatitis associated with metabolic dysfunction, belonging to the field of
biomedical technology. This invention provides the application of
secretin in the preparation of drugs for treating
steatohepatitis associated with metabolic dysfunction.
Cell model,
gene knockout,
in vivo complementation, and
exogenous protein intervention experiments were conducted, revealing that
secretin has significant
in vitro and
in vivo protective effects against
steatohepatitis associated with metabolic dysfunction.
In vitro, secretin can significantly improve
oleic acid-induced
lipid accumulation in hepatocytes, inhibit abnormal accumulation of lipid droplets in hepatocytes, reduce the expression of
inflammatory factors in hepatocytes, alleviate
hepatocyte inflammatory damage caused by lipotoxicity, and enter hepatocytes through
endocytosis. It can alleviate high-
fat diet-induced hepatic
steatosis and
inflammatory infiltration in MASH mice, and reduce the degree of
liver fibrosis.
