Biological process analysis revealed an enrichment of genes specific to septic arthritis that are involved in calcium ion cellular response, NF-κb signaling, TLR4 signaling pathway, cytokine response, actin cytoskeleton organization, etc., whereas the KEGG process revealed arthritis-specific enriched genes involved in NF-κb signaling. The gene discussed is NFKB1; the disease is bacterial arthritis.
