Functional annotation demonstrated that these DEGs were mainly involved in osteoclast differentiation, cytokine-cytokine receptor interaction, chemokine signaling pathway, lysosome and Staphylococcus aureus infection, focal adhesion, regulation of actin cytoskeleton, arrhythmogenic right ventricular cardiomyopathy (ARVC), oxytocin signaling pathway, and cGMP-PKG signaling pathway. Here, OXT is linked to arrhythmogenic right ventricular cardiomyopathy.
