The differentially expressed genes were analysed by KEGG enrichment analysis, and the top 10 pathways were as follows: Cardiac muscle contraction, Adrenergic signalling in cardiomyocytes, Oxytocin signalling pathway, Glycosaminoglycan biosynthesis-keratan sulfate, Arrhythmogenic right ventricular cardiomyopathy (ARVC), TGF-beta signalling pathway, cAMP signalling pathway, Insulin secretion, and Hypertrophic cardiomyopathy (HCM). This evidence concerns the gene OXT and hypertrophic cardiomyopathy.
