The top 20 KEGG terms included the metabolism of xenobiotics by cytochrome P450, arachidonic acid metabolism, cell adhesion molecules, pathways in cancer, PPAR signalling pathway, complement and coagulation cascades, glutathione metabolism, arginine and proline metabolism, cholesterol metabolism, and neuroactive ligand-receptor interactions (Fig. 6B and Table S5). Here, PPARA is linked to cancer.
