PPARA and gastric cancer: KEGG pathway enrichment analysis revealed that top 3 KEGG pathways enriched by upregulated DEGs were Glycosphingolipid biosynthesis, IL-17 signaling pathway and Bladder cancer and top 3 KEGG pathways enriched by downregulated DEGs were Osteoclast differentiation, PPAR signaling pathway and Gastric cancer pathway (Figure 5C).
