In the KEGG pathway analysis, the enriched biological processes were associated with pertussis, complement and coagulation cascades, Staphylococcus aureus infection, PPAR signaling pathway, systemic lupus erythematosus, coronavirus disease, alcoholic liver disease, Chagas disease, cholesterol metabolism, viral protein interaction with cytokines and cytokine receptors, diabetic cardiomyopathy, and cytokine–cytokine receptor interaction (Figure 8B). The gene discussed is PPARA; the disease is systemic lupus erythematosus.
