Metabolic networks are fundamental to cellular processes, driving energy production, biosynthesis, redox regulation, and cellular signaling. Recent advancements in metabolic research tools have provided unprecedented insights into cellular metabolism. Among these tools, the extracellular flux analyzer stands out for its real-time measurement of key metabolic parameters: glycolysis, mitochondrial respiration, and fatty acid oxidation, leading to its widespread use. This review provides a comprehensive summary of the basic principles and workflow of the extracellular flux assay (the Seahorse assay) and its diverse applications. We highlight the assay's versatility across various biological models, including cancer cells, immunocytes, Caenorhabditis elegans, tissues, isolated mitochondria, and three-dimensional structures such as organoids, and summarize key considerations for using extracellular flux assay in these models. Additionally, we discuss the limitations of the Seahorse assay and propose future directions for its development. This review aims to enhance the understanding of extracellular flux assay and its significance in biological studies.
代谢网络是细胞过程的基础,驱动着能量产生、生物合成、氧化还原调节和细胞信号转导。代谢研究工具的最新进展为细胞代谢提供了前所未有的见解。在这些工具中,由于能够实时测量糖酵解、线粒体呼吸和脂肪酸氧化等关键代谢参数,外切体流量分析仪脱颖而出,得到了广泛应用。本综述全面总结了外切体流量分析( Seahorse 分析)的基本原理和工作流程及其多样化的应用。我们强调了该分析在包括癌细胞、免疫细胞、秀丽隐杆线虫、组织、分离的线粒体以及类器官等多种生物模型中的多功能性,并总结了在这些模型中使用外切体流量分析的关键注意事项。此外,我们还讨论了 Seahorse 分析的局限性,并提出了该分析的未来发展方向。本综述旨在提高对外切体流量分析及其在生物学研究中的重要性的理解。
