Project description:We fed control mice and Slc7a11-LTG mice methionine and Choline Deficient (MCD) to induce NASH. Whole-genome RNA sequencing were then performed in the livers of control and LTG mice fed with MCD.
Project description:It is known that administration of MCD induces a severe state of hepatic fibrosis in mice. To attempt to elucidate molecular mechanism of hepatic fibrosis, we performed whole transcriptome analysis by microarray using RNAs prepared from liver of wild-type mice fed with normal diet (ND) or MCD.
Project description:It is known that administration of MCD induces a severe state of hepatic fibrosis in mice. Recently, many microRNAs (miRNAs) with pro- or anti-fibrotic properties have been identified during hepatic fibrosis. To attempt to elucidate molecular mechanism of hepatic fibrosis involved in miRNA fnction, we performed comprehensive analysis of miRNA expression by microarray using RNAs prepared from liver of wild-type mice fed with normal diet (ND) or MCD.
Project description:The microRNAs expression was markedly altered with the MCD diet. Using a custom microarray platform, we analyzed the expression levels of 1135 mouse microRNA probes in liver tissue that were fed MCD diet.
Project description:The genomic analysis of liver from mice fed with standard or methyl and choline deficient (MCD) diet and treated with dual agonist of GLP1R/GCGR during two weeks before 70% partial hepatectomy (PH) and after 2 weeks PH resulted in a set of genes regulated by diet and other set regulated differentially by treatment in MCD treated animals. These genes are apparently responsible for the reversion and prevention of NAS and improvement in hepatic regeneration induced by drug treatment All microarray analyses were performed with RNA samples obtained from four independent liver from animals with different diet and drug treatmens.

Project description:Chromatin immunoprecipitation DNA-sequencing (ChIP-seq) for the histone modifications H3K27ac and H3K9me3 in liver tissues from Methionine- and choline-deficient diet (MCD) and regular chow diet mice.
Project description:We performed survival analysis of control and MCD groups, and explored underlying tumor suppression mechanisms after dietary intervention, focused on alterations in the energy-dependent signaling pathways, histone modifications, and global gene expression differences on cDNA microarray study. Five- week- old male C57BL6 mice were randomly divided into two groups and fed control diet (control group, LabDiet, Brentwood, MO, USA) or moderate restriced carbohydrate diet formula (MCD, Treat group) in a specific pathogen free zone. All procedures were approved by the institutional animal use and care committee. Following a preliminary feeding of each diet formula for two week, HrasG12V / shp53 / GFP4 gene containing transposon vector were injected into mouse tail vein by hydrodynamic injection method. After 4 weeks of diet supplementation, all mice were sacrificed. Mouse liver tissue was excised for microarray analysis.
Project description:Recent studies have revealed the pivotal role of gut microbiota in the precession of liver diseases including non-alcoholic steatohepatitis (NASH). Many natural herbs, such as Gynostemma pentaphyllum (GP), have been extensively used applied in the treatment prevention of NASH, while the bioactive components and underlying mechanism remain unclear. The aim of this study was to investigate whether the polysaccharides of GP (GPP) has the protective effect on of NASH and to explore the potential mechanism underlying these effects. To investigate the function high dose of GPP(HGPP) in the regulation of hepatic gene expression, C57BL/6 male mice were fed with methionine-choline-deficient (MCD) diet for 4 weeks to induce NASH, and administered daily oral gavage of the sodium carboxymethylcellulose (CMC-Na) for model group, HGPP for experimental group, compared with normal control methionine-choline-sufficient (MCS) group.
