Genome-wide mapping of HIST1H2ac binding sites in MCF-7 cells

Previously, we have shown that HIST1H2ac is overexpressed in MCF-7 breast cancer cell line. It acts as a master regulator of estrogen receptor alpha-dependent gene expression in ER+ breast cancer cells. In the present study, we investigate the genome-wide protein DNA-binding events of HIST1H2ac protein in MCF-7 breast cancer cell line by over-expressing hemagglutinin (HA)-tagged HIST1H2ac and compared with MCF-7 cells over-expressing HA. The protein-bound DNA was recovered by immunoprecipitation using anti-HA antibody. The ChIP DNA and input DNA were sequenced with an Illumina HiSeq 2000 sequencer.
