Genome-wide maps of H3K27ac ocupancy on chromatin in murine acinar cell line upon EGF treatment and Arid1a silencing

Chromatin Immunoprecipitation-based sequencing (ChIP-seq) of H3K27ac was conduced in murine Kras-mutant acinar cell line 266-6 in the context of Arid1a-knockdown and/or EGF treatment. We found EGFR signaling activation as well as Arid1a silencing leads to additional increase of H3K27ac level genome-widely. And the maximal H3K27ac was achieved by the combined- EGF treatment and Arid1a knockdown. Examination of H3K27ac of Arid1a-intact- and knockdown cells with or without 8-hour EGF treatment.
