CALD1 and cancer: Gene Set Enrichment Analysis identified several immune-related and oncogenic KEGG pathways that were enriched in the high-CALD1 expression group (Figures 7A,B), including antigen processing and presentation, chemokine signaling, cytokine–cytokine receptor interaction, leukocyte transendothelial migration, vascular smooth muscle contraction, cell adhesion molecules, focal adhesion, MAPK signaling pathway, pathways in cancer, and TGF-beta signaling pathway.
