Snapshot results from WashU EpiGenome Browser. 5A, 5B, 5C, and 5D showed ChIP-seq and mRNA-seq results of EP300, Klf4, Notch2, and Igf2r gene, respectively. As shown in this figure, transcriptional level of each gene decreased in As treated group compared with control group. The signal of H3K27ac also decreased after treatment. CK* and CK, control group; As** and As, sodium arsenite exposed group.
