Provides mechanistic insight into superoxide-NO interactions in isolated vessels; leaves open relevance to in vivo or human endothelial dysfunction.
Does pretreatment with the SOD inhibitor DETCA alter NO-mediated endothelium-dependent vasodilator function in rat aortic smooth muscle?
Inhibition of Cu/Zn SOD in rat aortic smooth muscle impairs basal endothelial function by increasing superoxide anion, which inactivates basal nitric oxide.
Laight et al. (1998) studied this question.
