Gene set enrichment analysis indicates that the PPAR signaling pathway, oxidative phosphorylation, and Staphylococcus aureus infection pathways are significantly activated among the differentially expressed genes in acute pharyngitis (Fig. 7A–C), whereas these pathways are significantly suppressed in the differentially expressed genes treated with YYJH for acute pharyngitis (Fig. S4). Here, PPARA is linked to acute pharyngitis.
