ChIP assay of the recruitment of transcription factors to the SLC22A5 gene locus. a Schematic representation of the primers used to amplify the SLC22A5 promoter, intron 1, or intronic enhancer (within intron 2) regions. b Recruitment of ER, Nurr1, CREB1, ATF2, p300, CBP, and Pol II to the SLC22A5 promoter, intron 1, or intronic enhancer (within intron 2) regions. Data were presented as the relative amount of immunoprecipitated DNA normalized to input as measured by q-PCR assay. The data for vehicle-treated samples were arbitrarily set as 1
