Relative protein expression levels of PGK1 (p < 0.001), LDHA (p < 0.001), and HIF1A (p < 0.01) were notably upregulated in the DCM group, while QDYXD treatment significantly suppressed their expression (p < 0.05 for all comparisons) (Figures 9g, 9h, and 9i). This evidence concerns the gene HIF1A and familial dilated cardiomyopathy.
