Metabolic reprogramming is a hallmark of cancer. The changes in metabolism are adaptive to permit proliferation, survival, and eventually metastasis in a harsh environment. Stable isotope-resolved metabolomics (SIRM) is an approach that uses advanced approaches of NMR and mass spectrometry to analyze the fate of individual atoms from stable isotope-enriched precursors to products to deduce metabolic pathways and networks. The approach can be applied to a wide range of biological systems, including human subjects. This review focuses on the applications of SIRM to cancer metabolism and its use in understanding drug actions.
代谢重编程是癌症的一个标志。代谢变化具有适应性,以允许在恶劣环境中增殖、存活并最终发生转移。稳定同位素分辨代谢组学(SIRM)是一种利用核磁共振(NMR)和质谱的先进方法,来分析从稳定同位素富集前体到产物的单个原子的去向,从而推断代谢途径和网络的方法。该方法可应用于广泛的生物系统,包括人类受试者。本综述重点关注SIRM在癌症代谢中的应用及其在理解药物作用方面的用途。
