Dynamic histone modification at HCNEs during Drosophila development.

Table shows the percentage of HCNEs that were positive for any of the six analyzed histone modification markers or CBP binding across 12 developmental stages. A dash (−) indicates missing data. An HCNE is considered to have a given marker when at least 10% of its length overlapped with the marker. We observed a prominent presence of H3K27me3 and H3K9me3 among the HCNEs throughout development. Markers associated with the active chromatin state (H3K27ac, H3K9ac, and H3K4me3) displayed stage-specific patterns.Dynamic histone modification at HCNEs during Drosophila development.
