Description
Trimethylated histone H3-lysine 4 is primarily distributed in the form of sharp peaks, extending in neuronal chromatin on average only across 500-1500 base pairs mostly in close proximity to annotated transcription start sites. To explore whether H3K4me3 peaks could also extend across much broader domains, we undertook a detailed analysis of broadest domain cell-type specific H3K4me3 peaks in ChIP-seq datasets from sorted neuronal and non-neuronal nuclei in human, non-human primate and mouse prefrontal cortex (PFC), and blood for comparison. Overall design: We collected separately cortical gray (GM) and subcortical white matter (WM) from 6 adult human subjects without neurological disease and extracted total RNA processed by the RNA-Seq approach.
