Nitrite, long considered a biologically inert metabolite of nitric oxide (NO) oxidation, is now accepted as a physiological storage pool of NO that can be reduced to bioactive NO in hypoxic conditions to mediate a spectrum of physiological responses in blood and tissue. This graphical review will provide a broad overview of the role of nitrite in physiology, focusing on its formation and reduction to NO as well as its regulation of the mitochondrion- an emerging subcellular target for its biological actions in tissues.
亚硝酸盐长期以来被认为是一氧化氮(NO)氧化的生物惰性代谢产物,现在被公认为是NO的生理储存库,在缺氧条件下可还原为具有生物活性的NO,从而介导血液和组织中的一系列生理反应。本图文综述将广泛概述亚硝酸盐在生理学中的作用,重点关注其生成、还原为NO的过程以及对线粒体的调节——线粒体是其在组织中发挥生物学作用的一个新兴亚细胞靶点。
