HSPB1 and dilated cardiomyopathy: To explore potential ferroptosis or pyroptosis related genes in dilated cardiomyopathy, we intersected FRGs and PRGs with GSE17800's DEGS, and obtained 6 ferroptosis related differential genes including YY1AP1, CDKN1A, SRC, SESN2, CBS, and HSPB1 and 2 pyroptosis related differential genes including PRKACA and COL1A1 (Figure 6A).
