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,新陈代谢是由成千上万个相互作用的反应组成的。解开这种复杂性是理解细胞如何对遗传、环境或治疗扰动做出反应的关键。在这里,我们讨论了两个互补的战略分析基因组规模的代谢模型的作用:通量平衡分析(FBA)和网络科学。虽然FBA估计代谢通量的基础上的优化原则,网络方法揭示了全球代谢连接的新兴属性。我们强调了这两种方法的整合如何有望提供对代谢系统结构和功能的见解,并对发现科学、精准医学和工业生物技术产生广泛影响。

英文摘要:

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.
