Moreover, some important genes of the heart, such as the Ras-related associated with diabetes (RRAD), which may play an important role in cardiac antiarrhythmia [72], the ubiquinol-cytochrome c reductase core protein I (UQCRC1), which is involved in cardiomyopathies, and the solute carrier family 25 (mitochondrial carrier; phosphate carrier), member 3 (SLC25A3), whose deficiency is associated with hypertrophic cardiomyopathy [73] are inversely correlated with the expression of different miRNAs. The gene discussed is UQCRC1; the disease is diabetes mellitus.
