Secretome analysis of human liver

ABSTRACT: Non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH) are major contributors of chronic liver disease. There is an urgent need to identity non-invasive biomarkers for early diagnosis. This project preformed secretome analysis of >100 human liver samples with various stages of NAFLD and NASH to identify potential biomarkers.

Microarray analysis among non-alcoholic fatty liver, non-alcoholic steatohepatitis, and type 2 diabetes mellitus rats

Project description:Non-alcoholic fatty liver (NAFL) has the potential to progress to non-alcoholic steatohepatitis (NASH) or to promote type 2 diabetes mellitus (T2DM). However, NASH and T2DM do not always develop coordinately. We established rat models of NAFL, NASH, and NAFL + T2DM to recapitulate different phenotypes associated with NAFLD and its progression. Microarrays were used to identify hepatic gene expression changes in each of these models. The goal is to identify a predictor of different NAFLD progressions. Non-alcoholic fatty liver disease (NAFLD) is recognized as a low-grade systemic inflammatory state with both hepatic and extra-hepatic manifestations. We aimed to identify common key regulators and adaptive pathways in different NAFLD phenotypes. NAFL, NASH and NAFL+T2DM rat models were used to represent simple fatty liver, fatty liver with severe hepatic manifestations, and fatty liver with severe metabolic manifestations, respectively. We applied microarray analysis to characterize the key regulators and adaptive pathways in different NAFLD phenotypes. There are 12 samples in our study which belonged to 4 groups, and each group contains 3 different samples.

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

Expression data from human non-alcoholic fatty liver disease stages

Project description:Global gene expression patterns of 2 human steatosis and 9 human non-alcoholic steatohepatitis (NASH) together with their respective control patterns were analyzed to define the non-alcoholic fatty liver disease (NAFLD) progression molecular characteristics and to define NASH early markers from steatosis. Human liver samples of steatosis and non-alcoholic steatohepatitis were selected for RNA extraction and hybridization on Affymetrix microarrays. This dataset is part of the TransQST collection.

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.

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.

Macrophage-derived thrombospondin1 promotes obesity-associated non-alcoholic fatty liver disease

Project description:Thrombospondin 1 (TSP1) is a multifunctional matricellular protein. Previously we have shown that TSP1 plays an important role in obesity-associated metabolic complications including inflammation, insulin resistance, cardiovascular and renal disease. However, its contribution to obesity-associated non-alcoholic fatty liver disease (NAFLD) or non-alcoholic steatohepatitis (NASH) remains largely unknown and is determined in this study. High fat diet or AMLN diet-induced obese and insulin resistant NAFLD/NASH mouse models were utilized. In addition, tissue specific TSP1 knockout mice were utilized to determine the contribution of different cellular sources of obesity-induced TSP1 to NAFLD/NASH development. The data demonstrated that liver TSP1 levels were increased in experimental obese and insulin resistant NAFLD/NASH mouse models as well as in human obese NASH patients. Moreover, TSP1 deletion in hepatocyte or adipocytes did not protect mice from diet-induced NAFLD/NASH. However, myeloid/macrophage-specific TSP1 deletion protected mice against obesity-associated liver injury, accompanied by reduced liver inflammation and fibrosis. Importantly, this protection is independent of the levels of obesity and hepatic steatosis. Mechanistically, through an autocrine effect, macrophage-derived TSP1 suppressed SMPDL3B expression in liver, which amplified liver pro-inflammatory signaling (TLR4 signal pathway) and promoted NAFLD progression. Together, out data suggest that macrophage-derived TSP1 is a significant contributor to obesity-associated NAFLD/NASH development and progression and may serve as a therapeutic target for this disease.

Differential analysis of gene expression in liver tissues of patients with nonalcoholic fatty liver disease and controls.

Project description:Non-alcoholic fatty liver disease (NAFLD) comprises a collection of chronic liver disorders distinguished by the excessive accumulation of lipids within hepatocytes and the presence of steatosis. It covers a range of liver conditions that vary from simple steatosis (non-alcoholic fatty liver, NAFL) to non-alcoholic steatohepatitis (NASH). In this study, hepatic gene expression was compared among 6 patients with NAFL, 4 with NASH, and 6 healthy controls. All of these samples were collected prior to the liver transplantation procedure. Subsequently, differential genes were identified through comparative analysis of sequencing results, and target genes potentially related to the pathogenesis of NAFLD were further investigated. Numerous potential target genes and pathways have been identified in NAFLD, providing potential targets for therapeutic interventions.

Exosomal microRNA expression profiles of NASH: normal vs. NASH

Project description:Non-alcoholic fatty liver disease (NAFLD) is a predominant form of chronic liver disease, affecting nearly 25 % of the global population. The progression from steatosis to nonalcoholic steatohepatitis (NASH) in NAFLD patients is one of the major causes of liver-related death worldwide. We assessed the miRNA expression profiles of the exosomes derived from the peripheral blood of NASH patients or healthy controls.
