PPARA and hepatitis C virus infection: From the KEGG pathway results, the pathway with the most enriched genes is the neuroactive ligand-receptor interaction pathway (with 28 targets), then followed by pathways in cancer (with 20 targets), PPAR signaling pathway (with 11 targets), Th17 cell differentiation pathway (with 10 targets), cAMP signaling pathway (with 10 targets), calcium signaling pathway (with 9 targets), chemical carcinogenesis pathway (with 8 targets), hepatitis C (with 8 targets), estrogen signaling pathway (with 7 targets), and leishmania infection (with 6 targets) (Figure 5(b)).
