H4K16 acetylation marks active genes and enhancers of embryonic stem cells, but does not alter chromatin compaction [Agilent array]. Mus musculus

We report that acetylation of H4K16 is a new marker of active enhancers and that some enhancers are marked by H3K4me1, MOF and H4K16ac but not by acetylated H3K27 or p300, suggesting that they are novel p300-independent regulatory elements. Overall design: Gene expression in undifferentiated 46c (sox1-gfp) ES cells, and gfp FACS sorted cells after 5 days of differentiation to neural progenitor cells with NB27 and Neuro2 medium supplements. 3 biological replicates were performed for each sample.
