TP53 and viral myocarditis: The significant KEGG functional enrichment of DELs was ECM-receptor interaction (Figure 8), viral carcinogenesis (Figure 9), drug metabolism, cytochrome P450, p53 signaling pathway, nucleotide-binding oligomerization domain- (NOD-) like receptor signaling pathway, viral myocarditis, peroxisome proliferator-activated receptor (PPAR) signaling pathway, metabolism of xenobiotics by cytochrome P450, and riboflavin metabolism.
