Fig. 3.
Immunolocalization of histone PTMs in the nuclei of MSNs. Immunolocalization of histone acetylation (Left) including H3 acetyl-lysine14 (acK14) and acetyl-lysine18 (acK18), H4 acetyl-lysine5 (acK5), acetyl-lysine8 (acK8), and acetyl-lysine12 (acK12) and histone H3 methylation (Right) including lysine4 (H3K4) methylation (men) and lysine9 (H3K9) monomethylation (me), dimethylation (me2), and trimethylation (me3). DNA stained with DAPI (Center) and merged images (Right) are shown. Intense DAPI staining in large puncta corresponds to heterochromatin (usually less actively transcribed). (Scale bar, 5 µm.)
