Distribution of histone methylation signal among genomic features. C57BL/6J mice were treated with SEB + THC or SEB + vehicle, as described in the legend to Fig. 1. The LN cells were studied for histone markers as described under “Experimental Procedures.” a, the percentage of methylation signal located in the promoter regions (3 kb upstream of TSS), gene body (intron and exon), and intergenic region. b and c, the relative enrichment profile of each histone methylation near the TSS, within the transcript, and near the TTS in the SEB + vehicle-treated (b) and SEB + THC-treated (c) lymph node cells.
