Mechanism of Action of Nitric Oxide

There are several mechanisms by which NO has been shown to affect the biology of living cells. These include the oxidation of iron-containing proteins such as ribonucleotides reductase and Makoni tases, activation of soluble cyclase guanylates, ADP protein ribosylation, nitrosylation of sulfhydryl protein groups, and activation of iron regulating factor. NO has demonstrated activating NF-KB in mononuclear blood cells, an important transcription factor iNOS gene expression in response to inflammation. It is important for you to take nitric oxide supplements.

It has been found that NO acts through the soluble gluconate cyclase stimulation, which is a heterodimer enzyme with the subsequent cyclic-GMP formation. The GMP-cyclic activates the protein kinase G, which causes Ca2 + retrieval and the opening of the calcium-activated potassium channel. The decline in Ca2 + concentrations ensures that myosin light-chain kinase (MLCK) can not phosphorylate longer myosin molecules, thus stopping the cross-crosses cycle and causing smooth muscle cell relaxation. Oxygen-oxygen-oxide mixtures are used in critical care to demonstrate capillary and pulmonary dilatation to treat pulmonary hypertension in neonatal post-meconium aspirate and associated with birth defects.
