论文摘要
代谢在细胞生理学中起着核心作用,因为它为生长提供了分子机制。在基因组规模上,代谢由数千种相互作用的反应组成。解开这种复杂性是了解细胞对遗传,环境或治疗性扰动的反应的关键。在这里,我们讨论了两种互补策略在基因组级代谢模型分析中的作用:通量平衡分析(FBA)和网络科学。尽管FBA基于优化原则估计代谢通量,但网络方法揭示了全球代谢连接的新兴特性。我们强调了两种方法的整合如何有望提供对新陈代谢系统的结构和功能的见解,其在发现科学,精密医学和工业生物技术方面具有广泛的影响。
Metabolism plays a central role in cell physiology because it provides the molecular machinery for growth. At the genome-scale, metabolism is made up of thousands of reactions interacting with one another. Untangling this complexity is key to understand how cells respond to genetic, environmental, or therapeutic perturbations. Here we discuss the roles of two complementary strategies for the analysis of genome-scale metabolic models: Flux Balance Analysis (FBA) and network science. While FBA estimates metabolic flux on the basis of an optimisation principle, network approaches reveal emergent properties of the global metabolic connectivity. We highlight how the integration of both approaches promises to deliver insights on the structure and function of metabolic systems with wide-ranging implications in discovery science, precision medicine and industrial biotechnology.
