Nitric oxide reduces energy supply by direct action on the respiratory chain in isolated cardiomyocytes

To investigate the effecto f nitric oxide (NO) on cardiac energy metabolism, isolated cardiomyocytes of Wistar rats were incubated in an Oxystate system oat a constant ambient PO2 (25 mmHg) and oxygen consumption (VO2); free intracellular Ca2+ (fura 2), free cytosolic adenosine [S-adenosylhomocystei...
