(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) 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) Specific regulation of target genes by transforming growth factor-β (TGF-β) in a given cellular context is determined in part by transcription factors and cofactors that interact with the Smad complex. In the present study, we determined Smad2 and Smad3 (Smad2/3) binding regions in the promoters of known genes in HepG2 hepatoblastoma cells, and compared them to those in HaCaT epidermal keratinocytes to elucidate the mechanisms of cell type- and context-dependent regulation of transcription induced by TGF-β. more...

(Submitter supplied) Smad2/3 are transcription factors that engage in TGF-beta-induced transcription. We determined and analyzed HepG2 and Hep3B-specific Smad2/3 binding sites by ChIP-chip. We used expression microarrays to compare the Smad2/3 and HNF4alpha binding sites identified by ChIP-chip or ChIP-seq, respectively, to TGF-beta-induced gene expressions.

(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-4α (Hnf4α) is a transcription factor that controls epithelial cell polarity and maturation during embryogenesis. Hnf4α conditional deletion during post-natal development results in minor consequences on intestinal epithelium integrity but promotes activation of the Wnt/β-catenin pathway. Here we show that Hnf4α does not act as a tumor suppressor gene but is crucial to promote gut tumorigenesis in mice. more...

(Submitter supplied) HNF4a is an important liver transcription factor that regulates at least a thousand genes in the liver. Here we used expression profiling in HepG2 cells, a hepatocellular carcinoma cell line, in which HNF4a was knocked down by RNAi to identify some of those target genes. This dataset accompanies the article in Hepatology 2010 Feb;51(2):642-53.

(Submitter supplied) Gastric cancer is one of the most common cancers worldwide, with approximately 1 million patients being diagnosed annually. Better elucidating the mechanisms of tumorigenesis and aggressiveness is important for improving the therapeutic efficiencies of gastric cancer. Since our previous studies indicate that intelectin 1 (ITLN1) is aberrantly expressed in gastric cancer and serves as a prognostic factor for predicting the outcomes of gastric cancer patients, we hypothesized that ITLN1 might participate in the progression and aggressiveness of gastric cancer. more...
