Project description:Background and aims: Liver is a major target organ for alcohol-induced disease and the spectrum of pathological states elicited by alcohol in liver comprises steatosis, alcoholic steatohepatitis, progressive fibrosis and cirrhosis, conditions that may progress to hepatocellular carcinoma. Many experimental animal models of alcoholic steatohepatitis exist that vary in duration, mode of alcohol administration and the degree and types of liver injury produced. While most of these models, regardless whether alcohol is administered through liquid diet or intragastrically, produce steatohepatitis and mild fibrosis, it is widely acknowledged that these models fail to fully recapitulate key characteristics of severe forms of alcoholic liver disease, such as alcoholic hepatitis. Recent studies attempted to combine alcohol and fibrosis and achieved promising results in mouse models that achieve some of the key features of alcoholic liver disease accompanied by exacerbated fibrosis and acute renal injury. This study combined a chronic cholestatic liver fibrosis model induced by 3,5-diethoxycarbonyl-1,4-dihydrocollidine (DDC) with a mouse model of intragastric alcohol feeding. Methods: Adult male C57BL6/J mice were treated with 3,5-diethoxycarbonyl-1,4-dihydrocolidine (DDC) containing diet (0.05% w/w) to induce chronic liver fibrosis. Following DDC-induced fibrogenesis, ethyl alcohol (EtOH) (up to 27 g/ kg/day, up to 28 days) was administered continuously to mice via a gastric feeding tube (Tsukamoto-Frenchmodel of alcoholic liver disease). Results: Exposure to DDC or EtOH alone resulted in liver fibrosis or steatosis, respectively. Combined treatment with DDC and EtOH lead to an additive effect on liver injury, as evident by the development of hepatic inflammation, steatosis, and pericellular fibrosis, and by increased serum transaminase levels, compared to mice treated with either agent alone. Liver transcriptomic changes specific to combined treatment group included pathways involved in the cell cycle and DNA damage. Analyses of feces from these mice revealed alcohol-associated changes to the bile acid profile and gut microbiome. Conclusions: Mice treated with DDC and EtOH displayed several key characteristics of human alcoholic hepatitis, including pericellular fibrosis, increased hepatic bacterial load with dysbiosis, reduced capacity of the microbiome to synthesize secondary bile acids.

Project description:Background and aims: We aimed to study the pathogenesis of AH in an animal model of acute-on-chronic alcoholic liver disease which combines chronic hepatic fibrosis with intragastric alcohol administration. Methods: Adult male C57BL6/J mice were treated with CCl4 (0.2 ml/kg, 2×weekly by intraperitoneal injections for 6 weeks) to induce chronic liver fibrosis. Then, ethyl alcohol (EtOH) (up to 25 g/kg/day, for 3 weeks) was administered continuously to mice via a gastric feeding tube, with or without one-half dose of CCl4. Liver and serum markers were evaluated to characterize acute-on-chronic-alcoholic liver disease in our model. Results: CCl4 or EtOH treatment alone induced liver fibrosis or steatohepatitis, respectively, findings that were consistent with expected pathology. Combined treatment with CCl4 and EtOH resulted in a marked exacerbation of liver injury, as evident by the development of hepatic inflammation, marked steatosis, and pericellular fibrosis, and by increased serum transaminase levels, compared to mice treated with either treatment alone. Liver transcriptomic changes specific to combined treatment group demonstrated close concordance with pathways perturbed in human severe cases of AH. In addition to gene expression changes, E. coli and Candida species were also significantly more abundant in livers of mice co-treated with CCl4 and EtOH. Conclusions: Mice treated with CCl4 and EtOH displayed several key characteristics of human AH, including pericellular fibrosis, increased hepatic bacterial load, and dysregulation of the same molecular pathways. This model may be useful for developing therapeutics for AH.

Project description:To elucidate the effect of the polyphenols contained in alcoholic beverages on the metabolic stress induced by ethanol consumption, four groups of mice were fed for five weeks on Lieber's diet with or without ethanol, with ethanol plus ellagic acid, and with ethanol plus trans-resveratrol. Alcoholic fatty liver was observed in the group fed the ethanol diet but not in those fed the ethanol plus polyphenol diets. Liver transcriptome analysis revealed that the addition of the polyphenols suppressed the expression of the genes related to cell stress that were up-regulated by ethanol alone. Conversely, the polyphenols up-regulated the genes involved in bile acid synthesis, unsaturated fatty acid elongation, and tetrahydrofolate synthesis that were down-regulated by ethanol alone. Because parts of these genes were known to be regulated by the constitutive androstane receptor (CAR), we performed the same experiment in the CAR-deficient mice. As a result, fatty liver was observed not only in the ethanol group but also with the ethanol plus polyphenol groups. In addition, there was no segregation of the gene expression profiles among these groups. These results provide a molecular basis for the prevention of alcohol-induced stress by the polyphenols in alcoholic beverages. Five-week-old C3H/HeN female mice (CLEA, Japan) were acclimated to the maintenance condition (25°C, 8:00-20:00 day / 20:00-8:00 night cycle and 35~40 % humidity), fed a CE-2 diet (CLEA, Japan), and given water ad libitum for one week. Each group of mice (n=4 for wild type mice analysis and n=3 for CAR decficient mice analysis) was fed Lieber's isocaloric diet (Oriental yeast, Japan) containing water, containing ethanol, containing ethanol and ellagic acid (Fluka Biochemika, Switzerland), or containing ethanol and trans-resveratrol (Sigma, USA) (Supplementary Table 1) for one week at 10:00 ad libitum. Then, the mice were fed each diet at 12 g / day for four weeks (Supplementary Fig. 1A). The approximate intake of each polyphenol was 50 mg / kg body weight / day. At 10:00 of the final day of the experimental period, the animals were anesthetized by diethyl ether, sacrificed by cervial fracture, and the heart blood, and the liver were collected.

Project description:Scope: Alcoholic liver disease (ALD) is a major cause of chronic liver disease and is induced by alcohol consumption. Acetaldehyde produced by alcohol metabolism enhances the fibrosis of the liver through hepatic stellate cells. Additionally, alcohol administration causes the accumulation of reactive oxygen species (ROS), which induce hepatocyte-injury-mediated lipid peroxidation. The purpose of this study was to investigate the protective effects of iso-α-acids against alcoholic liver injury in hepatocytes in mice. Methods and results: C57BL/6N mice were fed diets containing isomerized hop extract, which mainly consists of iso-α-acids. After 7 days of feeding, acetaldehyde was administered by a single intraperitoneal injection. The acetaldehyde-induced increases in serum AST and ALT levels were suppressed by iso-α-acids intake. Hepatic gene expression analyses showed the upregulation of the glutathione-S-transferase, alcohol dehydrogenase and aldehyde dehydrogenase genes. In vitro, iso-α-acids induced the nuclear translocation of nuclear factor erythroid 2-like 2 (Nfe2l2; Nrf2), a master regulator of antioxidant and detoxifying systems, and upregulated the enzymatic activities of glutathione-S-transferase and aldehyde dehydrogenase. Conclusions: These results suggest that iso-α-acids intake prevents alcoholic liver disease injury by reducing oxidative stress via the Nrf2-mediated pathway.

Project description:Chronic alcohol abuse has a detrimental effect on the brain and liver. There is no effective treatment for these patients and the mechanism underlying alcohol addiction and consequent alcohol-induced damage of the liver/brain axis remains unresolved. We compared experimental models of alcoholic liver disease (ALD) and alcohol dependence in mice and demonstrated that genetic ablation of IL17 Receptor A (IL17ra-/-), or pharmacological blockade of IL17 signaling effectively suppressed the increased voluntary alcohol drinking in alcohol-dependent mice, and blocked alcohol-induced hepatocellular and neurological damage. The level of circulating IL17A positively correlated with the alcohol use in excessive drinkers, and was further increased in patients with ALD as compared to healthy individuals. Our data suggest that IL17A is a common mediator of excessive alcohol consumption and alcohol-induced liver/brain injury, and targeting IL17A may provide a novel strategy for treatment of alcohol-induced pathology.

Project description:Alcoholic liver diseases (ALDs) encompass a broad spectrum of clinical features of alcoholic fatty liver, alcoholic steatohepatitis and cirrhosis, and increased risk of hepatocellular carcinoma. While the toxic effects of alcohol likely result from complex interactions between genes and the environment, the molecular mechanisms of alcohol-induced liver damage remains undefined. Thus, a better understanding of the mechanisms regulating hepatic cell injury may lead to more effective therapeutic approaches for ALD. Here we compared the miRNA expression profile from tissues from control mice and mice receiving intragastric ethanol feeding. Four microarray hybridization studies were performed on three different pairs of liver-derived RNA from intragastric ethanol feeding and normal mice. The miRNAs differentially overexpressed in livers from ethanol fed mice.
