Genome-wide maps of H3K27ac, H3K4me1, JUN and p-JUN in JUN overexpressed or JUN inactivated fibroblasts

To further dissect whether and how activated JUN reconfigures the chromatin landscape, we performed Chromatin Immunoprecipitation (ChIP)-seq analyses for H3K4me1 and H3K27ac. Based on the significant increase of H3K27ac levels at H3K4me1+ sites, we identified 3,017 JUN-activated enhancers in JUN WT cells. In contrast, JUN AA fails to significantly induce H3K27ac accumulation at these regions. Their enrichment levels at JUN-activated enhancers were significantly decreased after JNKi treatment. Besides, these enhancers are directly driven by JUN, especially phosphorylated JUN. ChIP-seq of H3K27ac, H3K4me1, JUN and p-JUN in JUN overexpressed or JUN inactivated fibroblasts
