Chrysin attenuates hepatic steatosis and blood lipid dysregulation in a mouse model of nonalcoholic steatohepatitis
摘要
Abstract
AIM:To investigate the therapeutic effects of chrysin on nonalcoholic steatohepatitis(NASH).METHODS:Eight-week-old male C57BL/6 mice were randomly divided into control group,model group,and chrysin group.The mice in control group were fed with normal diet,and those in model and chrysin groups were fed with methio-nine-and choline-deficient(MCD)diet.After 5 weeks of adaptation,the mice in chrysin group received chrysin treatment(20 mg/kg)by continuous lavage for 6 weeks,while those in control and model groups were given equal volume of saline.During the experiment,the health condition of the mice was monitored.Liver morphology was examined after the mice were sacrificed.Serum triglyceride(TG),total cholesterol(TC),low-density lipoprotein cholesterol(LDL-C),high-den-sity lipoprotein cholesterol(HDL-C),alanine aminotransferase(ALT)and aspartate aminotransferase(AST)levels were measured using a biochemical analyzer.Liver tissue TG and TC levels were measured using assay kits.Liver cell damage and inflammation were assessed by hematoxylin-eosin(HE)staining and F4/80 immunohistochemistry staining.The ex-tent of liver lipid deposition was explored by oil red O staining.Masson staining and Sirius red staining were performed to assess liver fibrosis.Immunohistochemistry was performed to analyze the expression of fibrosis-related molecules.RE-SULTS:Compared with control group,the mice in model group showed significant decrease in body weight,liver wet weight,and liver volume.Serum TG,LDL-C,ALT and AST levels,as well as liver TG and TC levels were significantly elevated,and HDL-C levels were decreased in model group.Pathological staining showed significant inflammatory cell in-filtration,lipid deposition,and liver fibrosis.After the treatment with chrysin,increased body weight and liver weight,a reddish appearance of the liver,relatively smooth surface,and sharp liver edges were observed.Serum TG,LDL-C,AST and ALT levels,and liver TG levels were significantly reduced by chrysin.Inflammatory cell infiltration,lipid deposition,and liver tissue fibrosis were also significantly attenuated by chrysin.CONCLUSION:Chrysin shows a potential as a can-didate drug for the treatment of NASH by inhibiting hepatic steatosis,inflammation,and liver fibrosis.关键词
