Germinated barley downregulates hepatic stearoyl-CoA desaturase-1 enzyme gene expression in a hepatic steatohepatitis rat model

Steatohepatitis, fibrosis, and cirrhosis are common pathological features in the progression of hepatic steatosis. In the current work, we investigated the effect of germinated barely on the structure and function of the liver and its regulatory mechanism on SDC1 gene expression in a steatohepatitis rat model. Forty-eight adult male white Wistar rats were randomly divided into four groups: Group I, control; Group II, rats fed a germinated barley diet; Group III, rats fed a high-fat diet (HFD); and Group IV, rats fed both germinated barley (GB) and a high-fat diet for 14 weeks. Biochemical, histopathological, immunohistochemical, and morphometric studies, as well as qRT-PCR, were used to analyze the effect of germinated barley on steatohepatitis. The rats in Group IV had a lower liver index percentage and improved altered lipid profile and liver function tests compared to those in Group III. Supplementation of GB with a HFD ameliorated the histopathological features in the livers of rats fed a HFD, decreased the percentage of CD68-positive macrophages, and lowered the upregulated expression of SDC1. Supplementation of a HFD with GB prohibited the deterioration of liver function, lipid profile, and alteration of liver structure; it also decreased the associated hepatic inflammation and downregulated SDC1 in liver tissue.
