PPARA and staphylococcus aureus infection: KEGG pathway analysis indicated that DEmRNAs were primarily enriched in the interleukin-17 (IL-17) signaling pathway, herpes simplex virus-1 infection, Staphylococcus aureus infection, peroxisome proliferator-activated receptor (PPAR) signaling pathway, and arachidonic acid metabolism (Figure 4B and Supplementary Table 3).
