代谢的生化表征为理解健康和疾病的生物学提供了分子见解。在过去的几十年里,代谢紊乱与癌症、神经退行性疾病和糖尿病等有关。同位素追踪是一种允许通过生化反应追踪代谢物内标记原子的技术。这项技术已成为当代代谢研究的一个组成部分。同位素示踪测量底物对下游代谢物的贡献并表明其在细胞代谢网络中的利用。此外,同位素标记数据对于定量代谢通量分析是必要的。在这里,我们回顾了最近利用代谢追踪来研究健康和疾病的工作,并重点介绍了其在研究亚细胞、细胞间和体内代谢方面的应用。我们进一步讨论当前将同位素示踪的实用性扩展到新研究领域的挑战和机遇。
Biochemical characterization of metabolism provides molecular insights for understanding biology in health and disease. Over the past decades, metabolic perturbations have been implicated in cancer, neurodegeneration, and diabetes, among others. Isotope tracing is a technique that allows tracking of labeled atoms within metabolites through biochemical reactions. This technique has become an integral component of the contemporary metabolic research. Isotope tracing measures substrate contribution to downstream metabolites and indicates its utilization in cellular metabolic networks. In addition, isotopic labeling data is necessary for quantitative metabolic flux analysis. Here, we review recent work utilizing metabolic tracing to study health and disease, and highlight its application to interrogate subcellular, intercellular and in vivo metabolism. We further discuss the current challenges and opportunities to expand the utility of isotope tracing to new research areas.
