According to the bioinformatics results, we further validated expression of the five core PRGs (NLRP1, TNFα, CASP1, CASP9, and PRKACA) in healthy mouse myocardial tissue and Dox-induced DCM myocardial tissue (Figures 8(a) and 8(b)). This evidence concerns the gene CASP9 and familial dilated cardiomyopathy.
