The circadian clock regulates many aspects of physiology, including cardiovascular function. Internal oscillators exist in endothelial, smooth muscle cells, and fibroblasts of the vasculature. Vascular tone and thrombus formation, 2 key elements of vascular function with regard to adverse cardiovascular events, exhibit diurnal rhythmicity. In this review, we describe changes in vascular function that result from genetic disruption of discrete elements of the circadian clock.
生物钟调节着许多生理方面,包括心血管功能。内源性振荡器存在于血管的内皮细胞、平滑肌细胞和成纤维细胞中。血管张力和血栓形成是与不良心血管事件相关的血管功能的 2 个关键要素,表现出昼夜节律性。在这篇综述中,我们描述了由于生物钟离散元件的遗传破坏而导致的血管功能变化。
