KEGG pathway analysis of related DEPs and DEGs revealed significant enrichment for alcoholic liver disease, fatty acid degradation, β-alanine metabolism, the PPAR signaling pathway, the cell cycle, the ras signaling pathway, porphyrin metabolism, human immunodeficiency virus 1 infection, retrograde endocannabinoid signaling, and arginine and proline metabolism (Figure 4c). The gene discussed is PPARA; the disease is alcoholic liver diseases.
