Based on the KEGG enrichment analysis, in the comparison of M2 vs. D1, a total of 15 pathways were identified, which included terpenoid backbone biosynthesis, basal cell carcinoma, the IL-17 signaling pathway, the Wnt signaling pathway, the PPAR signaling pathway, and the TGF-beta signaling pathway (p < 0.05). This evidence concerns the gene PPARA and basal cell carcinoma.
