The enrichment results showed that, when the CTL group was compared with the PLC group, the differential metabolic pathways mainly involve primary bile acid biosynthesis, phenylalanine metabolism, fructose and mannose metabolism, choline metabolism in cancer, cholesterol metabolism, and bile secretion, etc. When the CTL group was compared with the JWXY group, the differential metabolic pathways mainly involve primary bile acid biosynthesis, phenylalanine metabolism, fructose and mannose metabolism, fatty acid biosynthesis, cholesterol metabolism, and bile secretion. The gene discussed is HSPG2; the disease is cancer.
