Class I histone deacetylases HDAC1, 2 and 3 are histone decrotonylases

We characterize histone crotonylation in intestinal epithelium-derived cells through Mass spectrometry, ChIp-Seq and RNA-Seq approaches and show that this modification is removed by class I histone deacetylases, HDAC1, 2 and 3. Overall design: RNA-Seq profile from mouse colon epithelium. ChIP-Seq experiments for H3K18crotonylation and H3K4me3 on mouse colon epithelium. ChIP-Seq experiments for H3K18 crotonylation and H3K18 acetylation on HCT116 cell line treated or not with the HDAC inhibitor MS275 (5 µM) for 18h. All the experiments were performed in triplicate.
