Furthermore, KEGG pathway analysis demonstrated that up-regulated co-DEGs participated in chemokine signaling pathway, cytokine-cytokine receptor interaction, IL-17 signaling pathway, rheumatoid arthritis, NF-κB signaling pathway, TNF signaling pathway, and Toll-like receptor signaling pathway (Fig. 3B). The gene discussed is NFKB1; the disease is rheumatoid arthritis.
