GSEA enrichment analysis of key genes, it was found to be mainly enriched in "Fatty acid degradation", "Peroxisome", "PPAR signaling pathway", "Steroid biosynthesis", "Fat digestion and absorption", "Fatty acid metabolism", "Glycerolipid metabolism", "Growth hormone synthesis, secretion and action", "Lipid and atherosclerosis", "Non-alcoholic Fatty liver disease", "Glycolysis hormone synthesis, secretion and action" (Figure 6c–f). The gene discussed is PPARA; the disease is metabolic dysfunction-associated steatotic liver disease.
