随着高灵敏度检测方法的快速发展,稳定同位素示踪技术受到越来越多的重视。该技术通过示踪原子追踪标记化合物在机体内的活动规律,依据中间代谢产物的同位素峰分布来判断其具体的代谢途径,通过计算通量对整个代谢通路进行综合分析,从而探究疾病的发生机制及药物代谢的途径和过程。近年来,稳定同位素示踪技术在生物医药领域的应用逐年增加,现主要针对其在糖、脂、氨基酸及激素等内源性物质代谢调控中的应用研究进展进行综述。

[Abstract]
With the rapid development of high-sensitivity detection methods, stable isotope tracing technique has received increasing attention. Stable isotope tracing technique can accurately track the activity of labeled compounds in the body through the tracer atoms and determine their specific metabolic pathways based on the distribution of isotopic peaks of the intermediate metabolites. By calculating the flux, the metabolic pathways are analyzed to provide a basis for the study of disease mechanism and drug metabolism. In recent years, the technique has a wide application in the field of biomedicine. This paper summarizes the applications of stable isotopic tracer technique in the metabolic regulation of endogenous substances such as carbohydrate metabolism, lipid metabolism, amino acid metabolism, hormone metabolism, nucleic acid metabolism, and so on.
