Specific histone modifications associated with gene activation are increased when flexible G0 is compromised. E2F was expressed in the posterior wing to delay cell cycle exit. At 26–28 h wings were dissected and immunostained for the indicated histone modifications and DAPI to label nuclei (A–J). The anterior–posterior boundary is indicated by a white line. The distribution of staining intensity in 217–1312 nuclei, binned into three ranges, is shown at right. Compromising flexible G0 specifically increases H3K27ac and H4K16ac. P values were determined by an unpaired t test; ****< 0.0001. Scale bars = 10 μm in A–J except for anterior (A) and posterior (P) zoomed images where the bar = 2 μm (e.g., BA, BP)
