细胞代谢在机体发育过程中起着至关重要的作用,但对细胞代谢的研究远远少于对发育过程的转录和表观遗传控制。这种困难可能主要归因于缺乏原位代谢物测定。基因编码荧光传感器是通过高度时空可视化实现活细胞和体内无创代谢监测的有力工具。在所有生物体中,NAD(H)和NADP(H)库对于维持氧化还原稳态和调节细胞代谢至关重要。在这里,我们介绍了NAD(H)和NADP(H)生物传感器,给出了在发育生物体中的示例分析,并描述了传感器如何促进发育生物学研究的前景。
Cell metabolism plays vital roles in organismal development, but it has been much less studied than transcriptional and epigenetic control of developmental programs. The difficulty might be largely attributed to the lack of in situ metabolite assays. Genetically encoded fluorescent sensors are powerful tools for noninvasive metabolic monitoring in living cells and in vivo by highly spatiotemporal visualization. Among all living organisms, the NAD(H) and NADP(H) pools are essential for maintaining redox homeostasis and for modulating cellular metabolism. Here, we introduce NAD(H) and NADP(H) biosensors, present example assays in developing organisms, and describe promising prospects for how sensors contribute to developmental biology research.
