ZFP36 and ischemic cardiomyopathy: By taking the intersection of the DEGs and ferroptosis related genes, 15 overlapped genes (MAP4, FZD7, MYH10, POR upregulated and HSPB1, FASN, HSPA9, EIF4A1, PLIN2, HSP90B1, AKR1C2, WTAP, MAP1LC3B, MYC, ATF4 downregulated) for ischemic cardiomyopathy (Figure 1D) and 17 overlapped genes (HSPB1, FASN, EIF4A1, PLIN2, HSP90B1, WTAP, YWHAZ, ZFP36, MAP1LC3B, POR, MYC, ATF4, SAT1 upregulated and MAP4, FZD7, MYH10, SNCA downregulated) for idiopathic cardiomyopathy (Figure 2D) were finally found to be included in the subsequent analyses.
