Mitochondrial DNA, mitochondrial dysfunction, and cardiac manifestations.

Abstract excerpt

Mitochondria, the powerhouses of cells, have their own DNA (mtDNA). They regulate the transport of metabolites and ions, which determine cell physiology, survival, and death. Mitochondrial dysfunction, including impaired oxidative phosphorylation, preferentially affects heart function via imbalance of energy supply and demand. Recently, mitochondrial mutations and associated mitochondrial dysfunction were...
