Endogenous nitric oxide is present in the exhaled air of rabbits, guinea pigs and humans. Nitric Oxide Regulation of Tissue Free Radical Injury. Protein–protein interactions among caveolin-1, calmodulin, and eNOS appear to alter availability of eNOS to signals within the caveolae; hence, a regulatory cycle exists, wherein Ca 2+ /calmodulin releases eNOS from the scaffolding domain of caveolin-1, thus permitting enzyme activity (97). The iNOS is primarily regulated at the expressional level by transcriptional and post-transcriptional mechanisms. Obstet Gynecol.
