Project description:A rat insulinoma cell line (INS-1) was generated that contains a FRT site for FLP recombinase mediated site specific integration of specific genes. In addition, the line contains the tetracycline repressor allowing tetracycline (tet) induction of the introduced gene. By comparing the gene expression profiles of uninduced and tet-induced cells, target genes of introduced transcription factors HNF1b, HNF4a2, and HNF6 (onecut1) were identified. Two different clones containing the same transcription factor were analyzed in the non-induced and tet-induced (24 h) state. Keywords: ordered

Project description:∼40,000 HNF6 binding sites were identified in mouse liver chromatin, including several thousand sites showing significant differences in level of HNF6 binding between male and female mouse liver. These sex-biased HNF6 binding sites showed strong enrichment for sex-biased DNase hypersensitive sites and for proximity to genes showing local sex-biased chromatin marks and a corresponding sex-biased expression. ~90% of genome-wide CUX2 binding sites identified previously in female mouse liver (Conforto TL, Zhang Y, Sherman J, Waxman DJ., Mol Cell Biol. 2012;32(22):4611-4627) were also bound by HNF6, giving evidence for genome-wide competition between HNF6 and CUX2 for chromatin binding in female mouse liver. These HNF6/CUX2 common binding sites were enriched for genomic regions more accessible in male than in female mouse liver chromatin, and showed strongest enrichment for male-biased genes, suggesting HNF6 displacement by CUX2 as a mechanism to explain the observed CUX2 repression of male-biased genes in female liver. However, HNF6 binding was sex-independent at a majority of its binding sites, and peak regions of HNF6 binding were frequently associated with co-binding by multiple other liver transcription factors, consistent with HNF6 playing a global regulatory role in both male and female liver. Livers were excised from individual male and female mice, cross-linked and sonicated, then used to identify HNF6 binding sites by ChIP-Seq using antibody specific to HNF6 (sc-13050; Santa Cruz Biotechnology, Inc).

Project description:Ovarian clear cell carcinoma (OCCC) is a morphologically and biologically distinct subtype of ovarian carcinomas. We previously reported a gene expression profile characteristic of OCCC (OCCC signature), which contains hepatocyte nuclear facter-1b ( HNF-1b). To elucidate the biological role of HNF-1b in OCCC, we performed the suppression of the HNF-1b expression in human ovarian cancer cell line RMG2 using short hairpin RNA. We are now evaluating the functional effect using these cells. Affimetrix Human Genome U133A plus 2.0 chips was conducted for HNF1b knockdown and non-silencing cells (five replicates each for RMG2-HNF1b-sh1 and RMG2-HNF1b-sh2, ten replicates for the RMG2-control). All specimens were arrayed in parallel and used for RMA normalization.

Project description:The aim of this study was to test, in vivo, if Foxa2 inhibits HNF6-mediated transcription in the liver. We utilized hepatocyte-specific gene ablation of Foxa2 and the Mouse PromoterChip BCBC 3.0 and Mouse PancChip 5.0 cDNA microarrays to investigate HNF6 binding to its target promoters in vivo in the presence or absence of Foxa2. For the mouse promoter microarray analysis, chromatin immunoprecipitation using anti-HNF6 antibodies was performed on chromatin isolated from Foxa2loxP/loxP Alfp.Cre and control mouse livers. Along with sheared genomic DNA (common reference), the immunoprecipitated DNA was amplified, labeled and hybridized to the Mouse PromoterChip BCBC 3.0. For microarray analysis of gene expression, liver RNAs were isolated from three Foxa2loxP/loxP Alfp.Cre and three control mice. RNAs were reverse transcribed, labeled, and hybridized to the Mouse PancChip 5.0. Overall, our studies demonstrate that HNF6 binds to and regulates its target promoters in vivo in the presence and absence of Foxa2 and that the expression levels of HNF6 targets are not influenced by Foxa2.
