PPARA and dilated cardiomyopathy: The top 10 enriched pathways were involved in metabolism (arachidonic acid metabolism, apelin signaling pathway, peroxisome proliferator-activated receptors (PPAR) signaling pathway, and cGMP-PKG signaling pathway), contractile function (cardiac muscle contraction, adrenergic signaling in cardiomyocytes, cAMP signaling pathway, and calcium signaling pathway), cardiac remodeling (dilated cardiomyopathy and hypertrophic cardiomyopathy).
