These DEGs were mainly enriched for some RNA‐related biological processes, such as RNA catabolic process, nuclear‐transcribed mRNA catabolic process (nonsense‐mediated decay), and nuclear‐transcribed mRNA catabolic process, and KEGG pathways such as viral myocarditis, cell‐adhesion molecules and regulation of lipolysis in adipocytes (e.g., FABP4, NPPA and MGLL). Here, MGLL is linked to viral myocarditis.
