Effect of HGPP on MCD-diet NASH on gene expression during liver of C57BL/6 mice

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. We performed gene expression profiling analysis using data obtained from RNA-seq of liver samples from three groups of mice (including normal group: MCS-induced group, model group: MCD-induced group, experimental group: HGPP group).
