Most importantly, the result of the KEGG analysis revealed that co-expressed genes and DEGs of BSG tended to enrich in the following terms: ECM-receptor interactions, complement and coagulation cascades, Staphylococcus aureus infection, p53 signaling pathway, and protein digestion and absorption (Fig. 7e, Table 3). The gene discussed is BSG; the disease is staphylococcus aureus infection.
