Meanwhile, “Retinol metabolism (mmu00830)”, “Protein digestion and absorption (mmu04974)”, “PPAR signaling pathway (mmu03320)”, “Steroid hormone biosynthesis (mmu00140)”, “Fat digestion and absorption (mmu04975)”, “Starch and sucrose metabolism (mmu00500)”, “Drug metabolism-cytochrome P450 (mmu00982)”, “Drug metabolism-other enzymes (mmu00983)”, “Arginine biosynthesis (mmu00220)”, and “Ascorbate and aldarate metabolism (mmu00053)” involved in metabolism were significantly enriched post infection. Here, PPARA is linked to infection.
