Diethyldithiocarbamate, an anti-abuse drug, alleviates steatohepatitis and fibrosis in rodents

ABSTRACT: C57BL/6 mice received methionine/choline deficient (MCD) diet to establish the model of non-alcoholic fatty liver disease (NAFLD) with or without Diethyldithiocarbamate (DDC) treatment. DDC improves hepatic steatosis, ballooning, inflammation and fibrosis in rodent models of NAFLD through modulating lipid metabolism and oxidative stress.

Transcription profiling by array to identify the effects of n-3 polyunsaturated fatty acids on non-alcoholic steatohepatitis in mice

Project description:The pathogenesis of non-alcoholic fatty liver disease (NAFLD) is associated with abnormalities of liver lipid metabolism, especially with the accumulation of saturated fatty acids (FA). On the contrary, a diet enriched with n-3 polyunsaturated FA (n-3-PUFA) has been reported to ameliorate the progression of NAFLD. The aim of our study was to investigate the impact of dietary n-3-PUFA enrichment on the development of NAFLD and liver lipidome. Mice were fed for 6 weeks either high-fat methionine choline-deficient diet (MCD) or standard chow (two groups fed MCD, two control groups, both with or without n-3-PUFA). Genome-wide transcriptome analysis of liver tissue was performed and revealed differences in liver mRNA transcriptomes after MCD as well as n-3-PUFA administration.

The critical and diverse roles of CD4-CD8- double negative T cells in non-alcoholic fatty liver disease

Project description:Methods: RNA transcription profiling of intrahepatic CD4-CD8- double negative T cells were compared between C57BL/6 mice fed with control diet and methionine-choline deficient diet (MCD) for 5 weeks. Results: RNA sequencing data showed that intrahepatic DNT in NAFLD mice exhibited markedly decreased Prf1, Gzmb but increased Il17a expression.

Impact of nonalcoholic fatty liver disease on toxicokinetics of tetrachloroethylene in mice

Project description:We report the effect of NAFLD on liver gene expression changes that could impact tetrachloroethhylene metabolism Methods: We fed male C57Bl/6J mice a base diet (BD), high fat (HFD), or methionine/choline/folate deficient high fat diet (MCD) for 8 weeks and then treated them with vehicle or tetrachloroethylene (PERC, 300 mg/kg ig). We only report "basal" differences herein (aka vehicle-treated). Results: We report that there were diet-specific differences in xenobiotic metabolizing genes, and that these genes may be responsible for NAFLD-induced disruption in PERC metabolism

Transcriptional profiling of mouse liver tissue following control, choline and methonine/choline deficient diet intervention

Project description:Choline and methionine/choline deficient diets are widely used to generate severe rodent hepatic steatosis and steatohepatitis in an attempt to reflect stages of human non-alcoholic fatty liver disease (NAFLD). The underlying mechanism of hepatic injury in these models, and how this reflects human disease remains incompletely understood. We used detailed transcriptional analysis to interrogate the molecular mechanisms of this intervention and its similarity to human disease. Adult C57Bl/6J mice were maintained on control, choline deficient (CDD) or methionine/choline deficient (MCDD) diets for 4 weeks. Isolated liver RNA was used for transcriptional profiling by micro array analysis.

Expression data from mouse liver treated with metformin

Project description:Optimal treatment for nonalcoholic steatohepatitis (NASH) has not yet been established, particularly for individuals without diabetes. We examined the effects of metformin, commonly used to treat patients with type 2 diabetes, on liver pathology in a non-diabetic NASH mouse model. Eight-week-old C57BL/6 mice were fed a methionine- and choline-deficient (MCD) + high fat (HF) diet with or without 0.1% metformin for 8 weeks.

Diethyldithiocarbamate, an anti-abuse drug, alleviates steatohepatitis and fibrosis in rodents through modulating lipid metabolism and oxidative stress.

Project description:Background and purposeDiethyldithiocarbamate (DDC) is a major metabolite of disulfiram that is a potential drug for alcoholism treatment. In the present study, we attempted to explore the possible effect of DDC on non-alcoholic fatty liver disease (NAFLD) and related fibrosis in vivo.Experimental approachC57BL/6 mice and Sprague Dawley (SD) rats received a methionine/choline-deficient (MCD) diet to establish the model of NAFLD with or without DDC treatment. The livers and serum were assessed for histological changes and parameters related to lipid metabolism, liver injury, inflammation and fibrosis. Apoptosis and macrophage related markers were assessed by immunohistochemistry (IHC).Key resultsDDC significantly reduced hepatic steatosis in rats with NAFLD, induced by the MCD diet. DDC reduced the oxidative stress and endoplasmic reticulum stress-related parameters in mice with non-alcoholic steatohepatitis, induced by the MCD diet. IHC for Bax and cleaved caspase-3 showed that DDC inhibited the apoptosis of hepatocytes in the liver. DDC significantly reduced ballooning and Mallory-Denk bodies (MDB) in hepatocytes, accompanied by suppression of serum alanine aminotransferase, aspartate aminotransferase and MDB formation-related genes. DDC significantly alleviated hepatic inflammation, accompanied by suppression of inflammation-related genes. DDC suppressed the infiltration of macrophages, particularly inducible NOS-positive pro-inflammatory macrophages. In addition, DDC significantly alleviated liver fibrosis. Microarray analyses showed that DDC strongly affected lipid metabolism and oxidative stress-related processes and pathways.Conclusion and implicationsDDC improves hepatic steatosis, ballooning, inflammation and fibrosis in rodent models of NAFLD through modulating lipid metabolism and oxidative stress.

Whole body Knockout of PC-TP (Pctp-/-), Hepatic whole RNAseq comparing Wild Type (WT) and knock out mic (KO) as well as Chow Fed and Methionine and choline depleted (MCD) fed mice.

Project description:Previous studies have used this model to show that PC-TP has a protective effect when challenged with a methionine and choline depleted diet, known to induce NAFLD. We performed transcription factor binding experiments and show that PPARs are dysregulated in the contect of PC-TP depletion We then performed gene expression profiling analysis using data obtained from RNA-seq of 3 Mice for WT and KO fed either normal chow or methionine and choline depleted chow.

Hepatocyte-specific knockout of Nicotinamide phosphoribosyltransferase increases susceptibility for liver fibrosis in mice

Project description:We investigated the plasma and liver proteome changes in liver fibrosis in mice induced by hepatocyte-specific knockout of nicotinamide phosphoribosyltransferase (Nampt) upon a low-methionine, choline-free 60% high-fat (MCD) diet at multiple time points. We also investigated whether supplementation with nicotinamide riboside could alleviate liver injury and how the liver proteome changes upon NR supplementation.

TSPO ameliorated the liver fibrosis in non-alcoholic fatty liver disease mice

Project description:The 18-kDa translocator protein TSPO is a conserved ubiquitous high affinity cholesterol binding protein localized in the outer mitochondrial membrane. It plays a critical role in the segregation and transport of cholesterol from the outer to the inner mitochondrial membrane in steroidogenic cells. Imaging studies in humans, using specific TSPO ligands, showed that TSPO is highly expressed and accurately mirrors the histological picture of non-alcoholic fatty liver disease (NAFLD)/nonalcoholic steatohepatitis (NASH). However, the functions of TSPO in simple steatosis (SS) and NASH are unknown. In the present study, we examined the TSPO functions with in vivo NAFLD model. To induce NASH in vivo, we fed the WT and TSPO KO rat with MCD (methionine-choline deficient) diet. Loss of TSPO ameliorated the liver fibrosis through down regulation of bile acid synthesis by reduction of CYP7A1 and CYP27A1 and increase of farnesoid X receptor (FXR).
