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.

Project description:FLORINASH - The role of intestinal microflora in non-alcoholic fatty liver disease (NAFLD) EU FP7-HEALTH, project number 241913<br>Florinash examined the role on the gut microbiota in NAFLD. Metagenomic, proteomic, metabolomic and transcriptomic data were integrated to give provide a systems biology approach to disease-associated studies. Liver biopsies were obtained from patients undergoing bariatric surgery; one was used to diagnose NAFLD, the other was used to examine the host transcriptome in NAFLD. This dataset is part of the TransQST collection.

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.

Project description:Non-alcoholic fatty liver disease (NAFLD) is of increasing prevalence and concern. NAFLD can progress to non-alcoholic steatohepatitis (NASH), to cirrhosis and finally to end-stage liver disease where liver transplantation is required. We aimed to characterise this progression by performing single nuclei transcriptomic analysis of liver biopsies taken from patients across the disease spectrum. We have observed that hepatocytes are the cell type affected mostly by the disease and describe plasticity between cell types which may represent a regenerative process.

Project description:Non-alcoholic fatty liver disease (NAFLD) is a common liver disorder and affects approximately one third of the general population.Recent studies have shown that long non-coding (lncRNA) plays critical roles in a myriad of biological processes and human diseases,Since the roles of lncRNA in NAFLD remain unknown,they were investigated in the study.Our findings indicate that the expression profiles of lncRNAs has changed in NAFLD as compared with normal liver, and may provide novel insight into the molecular mechanism underlying the disease and potential novel diagnostic or therapeutic targets for NAFLD. Microarray expression profiling of mRNAs and lncRNAs were conducted using RNA extracted from five NAFLD liver tissues and five normal liver samples.

Project description:Non-alcoholic fatty liver disease (NAFLD) is the most common chronic liver disorder in industrialized countries. Liver samples from morbidly obese patients with all stages of NAFLD and controls were analysed by array-based DNA methylation and mRNA expression profiling. Bisulphite converted DNA from the 85 samples were hybridised to the Illumina Infinium 450k Human Methylation Beadchip

Project description:Recent studies have identified a genetic variant rs641738 near two genes encoding membrane bound O-acyltransferase domain-containing 7 (MBOAT7) and transmembrane channel-like 4 (TMC4) that associate with increased risk of non-alcoholic fatty liver disease (NAFLD), non-alcoholic steatohepatitis (NASH), alcohol-related cirrhosis, and liver fibrosis in those infected with viral hepatitis1-7. Based on hepatic expression quantitative trait loci analysis it has been suggested that MBOAT7 loss of function promotes liver disease progression1-7, but this has never been formally tested. Here we show that Mboat7 loss, but not Tmc4, in mice is sufficient to promote the progression of NAFLD in the setting of high fat diet. Mboat7 loss of function is associated with accumulation of its substrate lysophosphatidylinositol (LPI) lipids, and direct administration of LPI promotes hepatic inflammatory and fibrotic transcriptional changes in an Mboat7-dependent manner. These studies reveal a novel role for MBOAT7-driven acylation of LPI lipids in suppressing the progression of N

We injected the substrate of MBOAT7, lysophosphatidylinostiol 18:0, or Saline in the portal vein of mice. The livers were then snap frozen and a standard RNA isolation was run to assess transcriptome changes after the addition of LPI's for six hours.
