The training set DEGs were enriched in 150 GO terms (Figure S2A and Table S9) and 8 KEGG pathways (Figure S2B and Table S10), the KEGG pathways were enriched in cytokine-cytokine receptor interaction (hsa04060), viral protein interaction with cytokine and cytokine receptor (hsa04061), neuroactive ligand-receptor interaction (hsa04080), staphylococcus aureus infection (hsa05150), tyrosine metabolism (hsa00350), PPAR signaling pathway (hsa03320), arachidonic acid metabolism (hsa00590) and IL-17 signaling pathway (hsa04657). Here, PPARA is linked to staphylococcus aureus infection.
