RCN3 and cancer: KEGG GSEA analysis demonstrated that RCN3 was mainly involved in “ECM − receptor interaction”, “cytokine-cytokine receptor interaction”, “focal adhesion”, “PI3K − Akt signaling pathway”, “chemokine signaling pathway”, “pathways in cancer”, and “Th1 and Th2 cell differentiation” in COAD, READ, MESO, LIHC, LGG, and KIRC (Supplementary Figure 6).
