HNF4α ChIP on mouse small intestinal epithelium. Chromatin immunoprecipitation analysis of HNF4α binding to HNF1α (Tcf1), phosphoenolpyruvate carboxykinase 1 (Pck1), apolipoprotein C3 (Apoc3), Cdx-2 (Cdx2), trehalase (Treh), and cingulin (Cgn) promoters in mouse small intestinal epithelium. An intron in the IgG gene served as a negative control (IgG). The analyzed promoter regions are all conserved between human and mouse. Enrichments are represented as percent of the total amount of genomic input DNA in ChIP. Significant enrichments are indicated (p-values < 0.001 is shown by ***, p-values < 0.05 is shown by *).
