过去二十年对一氧化氮的研究凸显了气体信号分子在生物学和医学中的根本重要性。一氧化碳和硫化氢 (H2S) 等其他气体的生理作用现在受到越来越多的关注。在这里,我们证明 H2S 在生理上是由胱硫醚 γ-裂合酶 (CSE) 产生的,并且小鼠体内这种酶的基因缺失显着降低了血清、心脏、主动脉和其他组织中的 H2S 水平。缺乏 CSE 的突变小鼠表现出明显的高血压和内皮依赖性血管舒张作用的减弱。 CSE 在生理上被钙钙调蛋白激活,钙调蛋白是响应血管激活而形成 H2S 的机制。这些发现提供了直接证据,证明 H2S 是一种生理性血管舒张剂和血压调节剂。
Studies of nitric oxide over the past two decades have highlighted the fundamental importance of gaseous signaling molecules in biology and medicine. The physiological role of other gases such as carbon monoxide and hydrogen sulfide (H2S) is now receiving increasing attention. Here we show that H2S is physiologically generated by cystathionine γ-lyase (CSE) and that genetic deletion of this enzyme in mice markedly reduces H2S levels in the serum, heart, aorta, and other tissues. Mutant mice lacking CSE display pronounced hypertension and diminished endothelium-dependent vasorelaxation. CSE is physiologically activated by calcium-calmodulin, which is a mechanism for H2S formation in response to vascular activation. These findings provide direct evidence that H2S is a physiologic vasodilator and regulator of blood pressure.
