Fig. 2

Relative expression of MYH6 and MYH7 genes in LV of healthy and failing human hearts. In the upper panels, the control samples are compared with all of the diseased samples, in the lower panels, the individual pathologies are analyzed separately (HCM—hypertrophic cardiomyopathy, DCM—dilated cardiomyopathy, ICM—ischemic cardiomyopathy, CAD—coronary artery disease). Plots represent the mean ± SEM gene expression ratio of both genes normalized to IPO8 and POLR2A. Data were statistically analyzed using Mann–Whitney test (upper panels) or ANOVA with Dunnett’s post hoc test (lower panels). * indicates p ≤ 0.05, ** indicate p ≤ 0.01, *** indicate p ≤ 0.001
