Recently, hepatic peroxisome proliferator-activated receptor (PPAR)γ has been implicated in hepatic lipid accumulation. We found that the C3H mouse strain does not express PPARγ in the liver and, when subject to a high-fat diet, is resistant to hepatic steatosis, compared with C57BL/6 (B6) mice. Adenoviral PPARγ2 injection into B6 and C3H mice caused hepatic steatosis, and microarray analysis d...
OBJECTIVE Insulin resistance contributes to the pathogenesis of both polycystic ovary syndrome (PCOS) and non-alcoholic fatty liver disease (NAFLD). The main aim of the present study was the evaluation of non-invasive indices of hepatic steatosis and fibrosis in PCOS women with or without metabolic syndrome (MetS). DESIGN In this cross-sectional study, three non-invasive indices for hepatic s...
Background: We studied the effects of serum iron level, hepatic iron deposition and other metabolic disorders i.e., insulin resistance in hepatic fibrosis development. Materials and methods: Among 60 patients with chronic hepatitis C, we measured serum iron, ferritin and transferrin level. Meanwhile, hepatic biopsies were obtained from 43 patients for whom iron deposition, inflammatory necrosi...
BACKGROUND Sirt6 has been implicated in the regulation of hepatic lipid metabolism and the development of hepatic steatosis. The aim of this study was to address the potential role of Sirt6 in the protective effects of rosiglitazone (RGZ) on hepatic steatosis. METHODS To investigate the effect of RGZ on hepatic steatosis, rats were treated with RGZ (4 mg·kg⁻¹·day⁻¹) by stomach gavage for 6 we...
Hepatic steatosis is defined when the deposition of triglyceride (TG) as lipid droplets in the cytoplasm of hepatocytes in more than 5% of hepatocytes. TG is a preferred storage nutrient as it provide greater caloric density (9 kcal/g) than do carbohydrates (4.5 kcal/g) or protein (4 kcal/g), and is insoluble in water, so they can accumulate to high levels with no adverse osmotic or colloidal e...
Mitochondrial dysfunction and endoplasmic reticulum (ER) stress have been implicated in hepatic steatosis and insulin resistance. The present study investigated their roles in the development of hepatic steatosis and insulin resistance during de novo lipogenesis (DNL) compared to extrahepatic lipid oversupply. Male C57BL/6J mice were fed either a high fructose (HFru) or high fat (HFat) diet to ...
IL-25 or IL-17E is a member of IL-17 cytokine family and has immune-modulating activities. The role of IL-25 in maintaining lipid metabolic homeostasis remains unknown. We investigated the effects of exogenous IL-25 or deficiency of IL-25 on hepatic lipid accumulation. IL-25 expression was examined in paraffin-embedded tissue sections of liver from patients or in the livers from mice. Mouse mod...
The aim of our work was to investigate the role of interleukin-33 (IL-33) and its receptor ST2 in the progression of diet-induced nonalcoholic steatohepatitis (NASH) in mice, and the characteristic expression in livers of patients with NASH. Mice were fed with high-fat diet (HFD) or methionine-choline 4-deficient diet (MCD) and injected intraperitoneally with IL-33. Both mRNA and protein expres...
To identify genetic and environmental factors contributing to the pathogenesis of non-alcoholic fatty liver disease, we examined liver steatosis and related clinical and molecular traits in more than 100 unique inbred mouse strains, which were fed a diet rich in fat and carbohydrates. A >30-fold variation in hepatic TG accumulation was observed among the strains. Genome-wide association stud...
