Figure 4. Endothelial cell (EC)-activating perturbations in vitro elicit EC subtype-specific transcriptional responses.
(A) Upset plots of up- and downregulated differentially expressed genes (DEGs) across EC subtypes with siERG (gray), IL1B (pink), and TGFB2 (blue). Upset plots visualize intersections between sets in a matrix, where the columns of the matrix correspond to the sets, and the rows correspond to the intersections. Intersection size represents the number of genes at each intersection. (B) Pathway enrichment analysis (PEA) for EC3-4 up- and downregulated DEGs with TGFB2 compared to control media. (C) PEA for EC2-4 up- and downregulated DEGs with IL1B compared to control media. (D) PEA for EC1-4 up- and downregulated DEGs with siERG compared to siSCR. (E) PEA comparing up- and downregulated DEGs that are mutually exclusive and shared between IL1B and siERG in EC3.
