The signaling pathways with significant differences between the experimental group and control group were as follows: (1) lipid metabolism–related signaling pathways: PPAR signaling pathway (mmu:03320), phototransduction signaling pathway (mmu:04744), arachidonic acid signaling pathway (mmu:00590), retinoic acid signaling pathway (mmu:00830); (2) immunology-related signaling pathway: NF-κb signaling pathway (mmu:04064)); (3) immune-related diseases: systemic lupus erythematosus (mmu:05322), asthma (mmu:05310), autoimmune thyroid diseases, and so forth. The gene discussed is PPARA; the disease is autoimmune thyroid disease.
