Transcription factor motif enrichment of chromatin accessibility reveals endotype-associated regulator differential activity. A TF motif enrichment of accessible ATAC-seq peaks (all peaks, promoter-associated peaks, and enhancer-associated peaks) using GimmeMotifs maelstrom with the SwissRegulon motif database. B chipenrich enrichment analysis of differentially accessible promoter-associated regions with increased accessibility (top) or decreased accessibility (bottom) using the GOBP and Hallmark ontology databases (Hallmark, H). C-D chipenrich enrichment analysis of differentially accessible enhancer-associated regions with differential accessibility using the (C) GOBP and Hallmark ontology databases or (D) ENCODE-ChEA Consensus and ReMap TF-gene target databases (ENCODE, E; ChEA, C; ReMap, R); FDR p-value < 0.05
