Through counting the number of both significantly hypo- and hypermethylated CpG dinucleotides mapping to each of these genomic elements, a clear trend emerged: promoters, gene bodies, and regions not mapping to promoters, genes or enhancers (red bars) were highly hypomethylated in insulinomas as compared to beta cells (~90% of CpGs) (red bars in Fig. 1c , Supplementary Data 7 , 8 ).
In addition, we identified a nominally significant enrichment for microglia/astrocyte OCRs in Alzheimer’s disease, which is consistent with a recent study implicating microglia enhancers in Alzheimer’s disease 38 The cell-specific map of chromatin accessibility generated in this study can be used to deconvolute bulk tissue ATAC-seq data from the human brain cortex.
