Chromatin immunoprecipitation of wild type and Foxa2 knock-out mouse liver using anti-HNF6 anitbodies to test whether Foxa2 inhibits HNF6-mediated transcription in the liver

ABSTRACT: 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 contro
