ScRNAseq and TCRseq of hepatic and splenic CD8T cells from normal diet fed (ND), HFHC diet fed (HFHC), and resolution induced (RES) mice.

ABSTRACT: To explore key features associated with the resolution process in liver fibrosis, we here applied a unique murine model, in which mice were fed HFHC diet for 24 weeks, and then continued with the HFHC diet (HFHC) or switched to a normal diet (RES) for 5 weeks. We noted that both the frequency and number of intrahepatic CD8+ T cells remained significantly high in RES mice compared to normal diet-fed mice (ND). To reveal the transcriptome profiling-based subtypes of CD8+T cells present during the liver fibosis resolution, we performed scRNA-seq analysis. Total of 25851 cells were clustered into 17 clusters based on the gene signatures. We revealed CD69+CD103-CD8+ Trm cell enrichment in fibrosis resolution livers. scTCR-seq analysis further revealed the clonal enrichment mainly in the Cd44+Sell-S1pr1- liver Trm fractions. In addition, TCR clonotypes enriched in liver CD8+ Trm cells of RES mice were expanded compared to those in liver CD8+ T cells of ND mice, and rarely detected in spleen CD8+ T cells.

Identification of eQTLs for Hepatic Xbp1s and Socs3 Gene Expression in Mice fed a High-Fat, High Caloric Diet

Project description:Non-alcoholic fatty liver disease (NAFLD) is a highly prevalent form of hepatic disease and feeding mice a High-Fat, High-Caloric (HFHC) diet is a standard model of NAFLD. In order to better understand the genetic basis of NAFLD, we conducted an expression quantitative trait locus (eQTL) analysis of mice fed a HFHC diet. 265 (A/J × C57BL/6J) F2 male mice were fed a HFHC diet for 8 weeks. QTL analysis was utilized to identify genomic regions that regulate hepatic gene expression of Xbp1s and Socs3. We identified two overlapping loci for Xbp1 and Socs3 on Chr 1 (164.0-185.4 Mb and 174.4-190.5 Mb, respectively) and Chr 11 (41.1-73.1 Mb and 44.0-68.6 Mb, respectively), and an additional locus for Socs3 on Chr 12 (109.9-117.4 Mb). C57BL/6J-Chr 11A/J/ NaJ mice fed a HFHC diet manifested the A/J phenotype of increased Xbp1s and Socs3 gene expression (p<0.05), while C57BL/6J-Chr 1A/J/ NaJ mice retained the C57BL/6 phenotype. In addition, we replicated the eQTLs on Chr 1 and 12 (LOD scores ? 3.5) using mice from the BXD murine reference panel challenged with CCl4 to induce chronic liver injury and fibrosis. We have identified overlapping eQTLs for Xbp1 and Socs3 on Chr 1 and 11, and consomic mice confirmed that replacing the C57BL/6 with the A/J Chr 11 resulted in an A/J phenotype for Xbp1 and Socs3 gene expression. Identification of the genes for these eQTLs will lead to a better understanding of the genetic factors responsible for NAFLD and potentially other hepatic diseases. Liver samples from eight-week-old AJ and C57BL6J males fed a High Fat High Calorie diet.

Changes of hepatic gene expression in C57BL/6N male mice fed high-fat high-calorie fructose (HFHC) diet for 8 weeks

Project description:In murine NAFL/NASH models, high-fat high-calorie fructose (HFHC) diet fed for 16 weeks induces hepatic steatosis, inflammatory cells infilatration and early stage fibrosis. In addition, HFHC diet 16 weeks but not 8 weeks is accompanied with weight gain and insulin resistance. The aim of this study is to determine the gene expression changes in mouse liver by HFHC diet for 8weeks.

MUTYH is associated with hepatocarcinogenesis in a NASH model mouse

Project description:Mice with MUTYH-null allele (Mutyh+/-, Mutyh-/-) were fed a high-fat/high-cholesterol (HFHC) diet or HFHC + high iron diet. The incidence of liver tumors and histological features of the liver were compared. We used microarray to examine the gene expression patterns associated with hepatocarcinogenesis in our model.

Gene expression data of livers from C57BL/6 fed a normal diet or high-fat-diet

Project description:Obesity is tightly associated with an increased risk of nonalcoholic fatty liver disease (NAFLD). However, the molecular mechanisms of obesity-induced fatty liver remain largely unknown.In order to identify genes that are potentially involved in dysfunctional hepatic lipid homeostasis in obesity, we performed a clustering analysis of Affymetrix arrays,which revealed that a number of mRNAs were dys-regulated in the livers of mice fed a high-fat diet (HFD), compared with mice fed a normal chow diet (ND). To identify genes that are potentially involved in dysfunctional hepatic lipid homeostasis in obesity, male C57BL/6 mice aged 8 weeks were fed a normal diet (ND) or high-fat-diet (HFD) containing 60 Kcal% of fat for 12 weeks. Then mice were sacrificed and total RNAs were isoloated from hepatic tissues. Affymetrix array hybridisation and scanning were performed using Mouse Genome 430 2.0 chips.Total RNA samples obtained from six mice per group (ND and HFD) and pooled by each of the two were used for microarray analysis.

Effects of NAFLD/NASH on hepatic gene expression.

Project description:To characterize gene expression changes in arachidonic acid metabolism pathway genes in the presense of non-alcoholic fatty liver disease (NAFLD)/non-alcoholic steatohepatitis (NASH) mice administered were administered an atherogenic diet for a period of four weeks. Administration of the atherogenic diet resulted in significant enrichment of the arachidonic acid metabolism pathway by gene set enrichment analysis (GSEA). The core enrichment subset of genes was down-regulated in mice administered the atherogenic diet and the majority of the genes that were down-regulated were cytochrome P450s. A total of 4 wild-type mice were administered a standard diet (STD; control group) and 4 wild-type mice were administered a HFHC diet (HFHC).

Albumosomes formed by pre-folding albumin in cytoplasm of hepatocytes maintain mitochondrial homeostasis and inhibit nonalcoholic fatty liver disease

Project description:Wildtype (WT) and albumin-knockout (AKO) were fed with normal diet. We harvested the liver tissues from WT and AKO mice at 3-week, 8-week, and 10-month of age. We then performed gene expression profiling analysis using data obtained from RNA-seq of the six different liver tissues. Wildtype (WT) and albumin-knockout (AKO) mice were fed with Normal diet (ND) or Western diet (WD) for 8 weeks from the age of 8 weeks. We harvested the liver tissues from WT-ND, WT-WD, AKO-ND, AKO-WD mice . We then performed gene expression profiling analysis using data obtained from RNA-seq of the four different liver tissues. Wildtype (WT) mice fed with HFD from the age of 8 weeks were injected by 17-AAG at the 3rd, 4th, 5th, 6.5th, and 8th weeks of the HFD feeding process. The control group was injected by the solvent. Another group of mice at the same age was fed with normal diet (ND). We harvested the liver tissues ND, Ctrl, and 17-AAG mice. We then performed gene expression profiling analysis using data obtained from RNA-seq of the three different liver tissues.
