The top 30 enriched KEGG pathways (Figure 5B) also showed that CNP might have an impact on intestinal processes of metabolism (protein digestion and absorption, mineral absorption, and fructose and mannose metabolism), immunity (PPAR signaling pathway, p53 signaling pathway, and IL-17 signaling pathway), and enteric disease (colorectal cancer, malaria, leishmaniasis, and legionellosis). The gene discussed is PPARA; the disease is colorectal cancer.
