PRC complexes can silence large regions in a cell-type-specific manner. (A) SUZ12 ChIP-chip analysis of a 500-kb region of the HOXA cluster, using three different cell lines. (B) SUZ12, EZH2, and H3me3K27 ChIP-chip analysis of a 500-kb region of the HOXA cluster, using human Ntera2 cells. The coding regions of the indicated genes are shown by the black boxes.
