Some of the significantlyaltered KEGG pathways were related to the innate immunity response, includingapoptosis, Staphylococcus aureus infection, lysosome, melanogenesis,TGF-beta signaling pathway, NOD-like receptor signaling pathway, PPAR signalingpathway, focal adhesion, toll-like receptor signaling pathway, and bacterial invasionof epithelial cells (Table 4). The gene discussed is PPARA; the disease is staphylococcus aureus infection.
