seven pathways (glyoxylate and dicarboxylate metabolism, primary bile acid biosynthesis, complement and coagulation cascades, PPAR signaling pathway, tryptophan metabolism, propanoate metabolism, and prion disease) were enriched by both GSEA of our prognostic model and KEGG pathway analysis of protein-coding genes of AS events associated SFs in the prognostic model. The gene discussed is PPARA; the disease is prion disease.
