Figure Lengend Snippet: a Chow-Ruskey diagram of Non-CORE Active Enhancer (non-CORE)-associated genes and Clustered Open Regulatory Element (CORE)-associated genes in PBMC. B cells (red border), Monocytes (purple border), T cells (green border), NK cells (brown border). Monocytes represent the union of CORE-associated genes derived from CD14+ Monocytes and CD16+ Monocytes, while T cells represent the combined set of CORE-associated genes derived from CD4 Memory T cells and CD8 Effector T cells. The color of the borders around each intersection corresponds to the cell types whose genes overlap. The area of each intersection is proportional to the number of genes within the intersection. b Proportion of CORE constituents that overlap with H3K4me1 peaks, relative to the total number of enhancer candidates in each cell type. NK: NK cells, CD14_Mono: CD14+ Monocytes, B: B cells, CD8_Teff: CD8+ Effector T cells, CD4_Tmem: CD4+ Memory T cells. c Heatmap for cell type-specific master regulators. Black: gene present in the CORE-associated genes of the given cell type. White: absent. d Log2-transformed fold changes of normalized TPM of genes in each cell type. Normalized TPM values were retrieved from the PBMC Monaco dataset in the Human Protein Atlas (HPA). Left: comparison between typical enhancer (TE)-associated genes and super-enhancer (SE)-associated genes. Right: comparison between non-CORE-associated genes and CORE-associated genes. P-value was calculated by a two-sided Wilcoxon signed-rank test. e Representative RNA expression for GATA3 , EBF1 , and MAFB . Normalized TPM values were retrieved from the HPA PBMC dataset. CD4 T Mem: CD4+ Memory T cells, CD8 T Mem: CD8+ Memory T cells, NK: NK cells, B mem: Memory B cells, B nai: naïve B cells, cDC: classical Dendritic cells, CD14 Mono: CD14+ Monocytes, CD16 Mono: CD16+ Monocytes. f Enrichment analysis of known TF motifs within CORE and non-CORE constituents across cell types. Colored by enrichment score, modified MinMax-scaled statistical significance (-log10(P-value)).
Article Snippet: To investigate cell type-specific transcriptional regulation of CORE-associated and SE-associated genes in PBMC, we utilized the Monaco PBMC RNA-seq dataset and the HPA PBMC RNA-seq dataset from the Human Protein Atlas (HPA; https://www.proteinatlas.org/ ) [ ].
