In the KEGG signaling pathway analysis, the host genes were significantly enriched in 16 terms; dilated cardiomyopathy (map05414), thermogenesis (map04714), the PPAR signaling pathway (map03320), and oxidative phosphorylation (map00190) were the most significant (Figure 2(b)). The gene discussed is PPARA; the disease is dilated cardiomyopathy.
