(Submitter supplied) The goal of this experiment was to distinguish those genes regulated following acute HNF4alpha depletion compared to a developmental knockout model where gene compensation may comfound results. Expression profile of livers from 8 week old male Hnf4alpha Flox mice that express either albumin cre or the tamoxifen inducible ErT2-albumin cre for liver-specific deletion. Mice were fed a control diet or tamoxifen diet in the case of the ErT2-albumin cre to induce recombination.

(Submitter supplied) Neonatal liver-derived rat epithelial cells (rLEC) from biliary origin are liver progenitor cells that acquire a hepatocyte-like phenotype upon sequential exposure to hepatogenic growth factors and cytokines. Undifferentiated rLEC express several liver-enriched transcription factors including the hepatocyte nuclear factors (HNF) 3β and HNF6, but not the hepatic master regulator HNF4α. In this study, we investigated the impact of the ectopic expression of HNF4α in rLEC on both mRNA and microRNA level by means of microarray technology. more...

(Submitter supplied) A previous study from this laboratory demonstrated that up-regulating HNF4a could reverse the malignant phenotypes of HCC by inducing redifferentiation of HCC cells to hepatocytes. To study the mechanisms of the hepatic differentiation effect by HNF4α, we used the cDNA microarray to detect differential gene expression profiles of Hep3B infected with AdHNF4α and AdGFP. Expression profile analysis revealed that HNF4α positively regulated 1218 mRNAs and negatively regulated 1411 mRNAs for more than 2 times. more...

(Submitter supplied) MicroRNAs is a rapidly expanding area expected to change the way in which diseases will be diagnosed, treated and monitored in the future. Hepatocellular carcinoma (HCC) shows a rising incidence with high mortality but lack of effective targeted therapies. We identified the aberrantly expressed miRNAs involved in HCC through the comparison of miRNA expression profiling in cancerous hepatocytes with that in normal primary human hepatocytes and found 37 dysregulated miRNAs in HCC. more...

(Submitter supplied) Nuclear factor κB (NF-κB) pathway plays an important role in hepatocellular carcinoma (HCC) progression. miR-194 was previously shown to reduce the induction of NF-κB activity upon addition of tumor necrosis factor α (TNFα). To clarify the molecular mechanism responsible for the effect of miR-194 on NF-κB pathway, mRNA microarray assays were performed to identify the genes that were suppressed by miR-194.

(Submitter supplied) A series of dual-channel gene expression profiles obtained using Rosetta/Agilent Whole Mouse Genome oligonucleotide microarrays, 4 x 44K format, was used to identify sex-dependent and HNF4alpha-dependent differences in gene expression in adult mouse liver. This series is comprised of four sex-genotype combinations: adult male wild-type liver (M-WT), adult female wild-type liver (F-WT), adult male liver-specific HNF4alpha knockout liver (M-KO) and adult female liver-specific HNF4alpha knockout liver (F-KO). more...

(Submitter supplied) To obtain a genomic view of hepatocyte nuclear factor-4α (HNF-4α) in the regulation of the inflammatory response, microarray analysis was used to probe the expression profile of an inflammatory response induced by cytokines in a model of knock-down HNF-4α HepG2 cells. The results indicate an extensive role for HNF-4α plays in the regulation of a large number of the liver-specific genes. Majority of genes (71%) affected by cytokine treatment are also affected by HNF-4α knock-down. more...

(Submitter supplied) Physiologically, albumin is produced by hepatocytes. It remains largely unknown how patients are capable of maintaining essential albumin levels even in the condition of liver failure. Here, we delineate a hierarchical regulatory network that controls albumin transcription under different pathophysiological conditions. The ALB core promoter possesses a TATA box and nucleosome-free area, which allows constitutive binding of RNA Pol II and thus initiation of transcription. more...

(Submitter supplied) Background & Aims: HNF4α is an important transcriptional regulator of hepatocyte and pancreatic function. Hnf4α deletion is embryonically lethal with severe defects in visceral endoderm formation, liver maturation and colon development. However, the precise role of this transcription factor in maintaining homeostasis of the adult intestine remains unclear. Herein, we aimed to elucidate the adult intestinal functions of Hnf4α. more...

(Submitter supplied) Background and Aims: HNF4a is a nuclear hormone receptor transcription factor that has been shown to be required for hepatocyte differentiation and development of the liver. It has also been implicated in regulating expression of genes that act in the epithelium of the lower gastrointestinal tract. This implied that HNF4a might be required for development of the gut. Methods: We generated mouse embryos in which HNF4a was ablated in the epithelial cells of the fetal colon using Cre-loxP technology. more...

(Submitter supplied) Hepatocyte Nuclear Factor 4 alpha (HNF4α), a master regulator of hepatocyte differentiation, and circadian regulator Aryl Hydrocarbon-Like Receptor-Like 1 (ARNTL, or BMAL1) though robustly co-expressed in healthy liver, are incompatible within the context of HCC. Differential expression of Bmal1 and Hnf4α may control susceptibility to liver disease and ultimately, hepatocellular carcinoma. We compared gene expression profiles under conditions of inducible loss of hepatic Hnf4α and inducible loss of Hnf4a and Bmal1 in this RNA-seq experiment. more...

(Submitter supplied) Oligo-fucoidan (OF), a sulfated polysaccharide extracted from brown seaweed, exhibits anti-inflammation and antitumor effects, however, knowledge concerning the detailed mechanism of oligo-fucoidan on liver cells is obscure. In this study, we investigate the effect of oligo-fucoidan in normal hepatocytes using transcriptomic analysis. Using an oligo-fucoidan oral gavage in adult wild-type zebrafish, we then used microarrays to detail the global programme of gene expression after fucoidan treatment and identified distinct classes of up- and down-regulated genes during this process.
