PPARA and hypertrophic cardiomyopathy: Pathway enrichment analysis results suggested that the mechanisms mainly included MAPK signaling pathway, Calcium signaling pathway, Dilated cardiomyopathy, Hypertrophic cardiomyopathy (HCM), and PPAR signaling pathway, etc. MAPK signaling pathway is an important pathway involved in cellular proliferation and migration, regulating myocyte contractility and cell death in cardiomyocytes (Wang, 2007; Back et al., 2015).
