The effects of CD4 T cell Nr4a family on NASH progression

ABSTRACT: NASH is characterized by hepatic steatosis, inflammation, fibrosis and liver damage, which eventually results in liver dysfunction due to cirrhosis or hepatocellular carcinoma. However, the cellular and molecular mechanisms underlying NASH progression remain largely unknown. In this study, we aimed to elucidate the impact of Nr4a family in CD4 T cells in NASH development.

Post-transplant (non-alcoholic steatohepatitis) NASH compared with transplanted normal controls

Project description:Non-alcoholic fatty liver disease (NAFLD) encompasses a spectrum of disease that ranges from simple steatosis, to inflammatory form non-alcoholic steatohepatitis (NASH), cirrhosis, and up to hepatocellular carcinoma. While NASH usually takes decades to develop at a rate of one stage per seven years, in the case of post-trasplant NASH (pt-NASH) develops fibrosis much more rapidly, with almost 50% of liver transplant recipients presenting stage 3 fibrosis by 5 years post-transplant. Archived fresh-frozen transplanted liver biopsy samples from four liver biopsy samples with evidence of NASH (2 recurrent and 2 de novo), two with simple steatosis (both de novo), and five with normal histology as controls had their transcriptome sequenced in two batches for deeper coverage.

The synergestic effects of western diet and carbon tetrachloride (CCl4) to develop non-alcoholic steatohepatitis (NASH) and liver tumor in mice

Project description:NASH is a combination of hepatic steatosis and severe inflammation, which can lead to fatal liver disease such as cirrhosis and hepatocellular carcinoma. While a variety of models have been descirbed, they have several limitations. Therefore, it is of urgent importance to create animal model that recapitulate the physiology, histology and outcome seen in human with NASH. We created western diet-fed and CCl4-treated mouse model. they showed characteristic histological features of NASH such as fibrosis, ballooning and steatosis at 12 weeks and liver cancers developed at 24 weeks. Their transcritomic changes were also similar to those seen in human NASH.

NASH

Project description:Non-alcoholic fatty liver disease (NAFLD) is characterized by a series of pathological changes that can progress from simple fatty liver disease to non-alcoholic steatohepatitis (NASH). The objective of this study is to describe changes in global gene expression associated with the progression of NAFLD. This study is focused on the expression levels of genes responsible for the absorption, distribution, metabolism and excretion (ADME) of drugs. Differential gene expression between three clinically defined pathological groups; normal, steatosis and NASH was analyzed. The samples were diagnosed as normal, steatotic, NASH with fatty liver (NASH fatty) and NASH without fatty liver (NASH NF). Genome-wide mRNA levels in samples of human liver tissue were assayed with Affymetrix GeneChipM-. Human 1.0ST arrays

Tid1 Deficiency Disrupting Mitochondria to Drive NASH-Dependent Hepatocellular Carcinoma Progression

Project description:Non-alcoholic fatty liver disease/steatohepatitis (NAFLD/NASH) is a significant risk factor for hepatocellular carcinoma (HCC). However, a preclinical model of progressive NAFLD/NASH is largely lacking. Here, we report that mice with hepatocyte-specific deletion of Tid1, encoding a mitochondrial cochaperone, tended to develop NASH-dependent HCC. Mice with hepatic Tid1 deficiency showed impairing mitochondrial function and causing fatty acid metabolic dysregulation; meanwhile, sequentially developed fatty liver, NASH, and cirrhosis/HCC in a diethylnitrosamine (DEN) induced oxidative environment. The pathological signatures of human NASH, including cholesterol accumulation and activation of inflammatory and apoptotic signaling pathways, are also present in these mice. Clinically, low Tid1 expression was associated with unfavorable prognosis in patients with HCC. Empirically, hepatic Tid1 deficiency directly disrupts entire mitochondria that play a key role in the NASH-dependent HCC development. Overall, we established a new mouse model that develops NASH-dependent HCC and provides a promising approach to improve the treatment.

circRNA expression profiles of fibroblasts: normal vs. NASH cirrhosis

Project description:The progression from steatosis to nonalcoholic steatohepatitis (NASH) in nonalcoholic fatty liver disease (NAFLD) patients is one of the major causes of liver-related death worldwide and have limited effective therapies. We comparing the circular RNomics of liver fibroblasts isolated from patients with NAFLD-caused cirrhosis and the ones without NAFLD.

Combination of an ACLY inhibitor with a GLP-1R agonist exerts additive benefits on NASH and hepatic fibrosis [NASH Custom panel]

Project description:Increased liver de novo lipogenesis (DNL) is a hallmark of nonalcoholic steatohepatitis (NASH). A key enzyme controlling DNL upregulated in NASH is ATP citrate lyase (ACLY). In mice, inhibition of ACLY reduces liver steatosis, ballooning and fibrosis and inhibits activation of hepatic stellate cells. Glucagon like peptide-1 receptor (GLP-1R) agonists lower body mass, insulin resistance and steatosis without improving fibrosis. Here, we find that combining an inhibitor of liver ACLY, bempedoic acid, and the GLP-1R agonist liraglutide reduces liver steatosis, hepatocellular ballooning, and hepatic fibrosis in a mouse model of NASH. Liver RNA analyses revealed additive downregulation of pathways that are predictive of NASH resolution, reductions in the expression of prognostically significant genes compared to clinical NASH samples, and a predicted gene signature profile that supports fibrosis resolution. These findings support further investigation of this combinatorial therapy to treat obesity, insulin resistance, hypercholesterolemia, steatohepatitis, and fibrosis in people with NASH.

Whole transcriptome profiling of Japanese nonalcoholic fatty liver disease cohort.

Project description:Nonalcoholic steatohepatitis (NASH) is a severe form of nonalcoholic fatty liver disease (NAFLD) that is characterized by hepatic steatosis, inflammation, hepatocellular injury, and fibrosis, which lead to progressed cirrhosis and hepatocellular carcinoma. Despite its increasing prevalence on a global scale, the pathogenesis of NASH progression is not well understood. To elucidate the underlying mechanisms of NASH progression, we conducted transcriptome analyses of Japanese NAFLD cohort in our facility.

Hepatic transcriptomic changes during non-alcoholic steatohepatitis (NASH)-associated liver carcinogenesis in mice

Project description:Hepatocellular carcinoma (HCC), which accounts for 90% of all primary livers tumors, is the fourth most common cancer in the world. The development of HCC is a long-term and complex process, and uncovering the molecular mechanisms associated with HCC development is critical for the disease diagnosis, prevention, and treatment. Exploring these mechanisms using human HCC samples is desirable, but frequently impractical, with a number of limitations and shortcomings. The STAMTM (Stelic Institute & Co, Tokyo, Japan) mouse model of NASH-associated liver carcinogenesis is considered a useful and relevant model for investigating the molecular pathogenesis of NASH-derived HCC. This model resembles the human HCC development associated with progression from simple steatosis to NASH, fibrosis, and HCC. In the present study, by using high-throughput whole genome microarrays (SurePrint G3 Mouse Gene Expression v2, 8x60K; Agilent Technologies, Santa Clara, CA), we examined the transcriptomic profiles in the livers of STAMTM mice at different stages of liver carcinogenesis, including steatosis (6 week time interval), NASH (8 weeks), fibrotic stage (12 weeks), and in full-fledged HCC (20 weeks). The results of microarray analyses showed significant progressive changes in hepatic gene expression during the development of HCC. A total of 970, 1462, 2742, and 2857 of differentially expressed genes were identified in the livers at 6, 8, 12, and 20 weeks, respectively. Detailed analysis of these differentially expressed genes will benefit the understanding of the underlying mechanisms of non-alcoholic fatty liver disease-derived HCC. Transcriptomic profile in the liver of STAM mice at 6 weeks (steatosis; n=3), 8 weeks (steatohepatitis; n=3) 12 weeks (fibrosis; n=4) and 20 weeks (HCC-stage tumor tissue, n=4) weeks. Age-matched control samples were also analyzed.
