3502252 Griffith TM, Edwards DH, Henderson AH: Unstimulated release of endothelium derived relaxing factor is independent of mitochondrial ATP generation. Cardiovasc Res. 1987 Aug;21(8):565-8.


Since haemoglobin inhibits and the cyclic GMP phosphodiesterase inhibitor, MB22948, amplifies endothelium dependent relaxation they were used to provide evidence of basal activity of endothelium derived relaxing factor (EDRF).

The reoxygenation relaxation was, however, sensitive to very low levels of oxygen and was inhibited by cyanide and rotenone, suggesting an involvement of mitochondrial metabolism.
Mechanisms underlying endothelium-dependent effects of oxygen include the sensitivity of the nitric oxide/endothelium-derived relaxing factor (EDRF), hydrogen peroxide, and eicosanoid pathways.

Previous studies have suggested that systemic artery endothelial cell production of the nitrovasodilator endothelium-derived relaxing factor (EDRF) is dependent upon oxidative energy production.
In aortic rings, 0.1 microM rotenone and 0.1 microM antimycin A, and, to a lesser extent, 50 mM 2-deoxyglucose, inhibited endothelium-dependent relaxation to acetylcholine and adenosine diphosphate.

These data suggest that in rabbit and in rat aorta, rotenone inhibits acetylcholine-induced relaxation by inhibiting EDRF production, and by depressing smooth muscle sensitivity to EDRF, respectively.

The content of adenosine triphosphate (ATP) and basal and bradykinin-stimulated production of prostacyclin and endothelium-derived relaxing factor (EDRF) was measured in primary cultures of porcine aortic endothelial cells under normoxic (14.4% O2) and hypoxic (2.8% O2) conditions, and following treatment with rotenone and 2-deoxy glucose, which inhibit oxidative and glycolytic metabolism, respectively. 2.

However, the chemical identity of endothelium-derived relaxing factor (s) (EDRF) and the mechanisms underlying its synthesis and release remain unclear.
In contrast, inhibition of oxidative metabolism with either 1 mM amytal or 5 microM rotenone markedly impaired relaxation to acetylcholine.
