微生物表型与其网络结构之间的强关联

Strong associations between microbe phenotypes and their network architecture

Soumen Roy, Vladimir Filkov

摘要:

理解生物网络中结构和功能之间的依赖性和相互作用对疾病进展、生物制造和一般生物系统具有重要意义。我们提出了评估各种微生物特征和表型与其网络拓扑结构之间关系的方法。我们采用了一种自动化的方法来表征代谢网络的32种微生物使用复杂网络的11个拓扑度量。聚类允许我们提取不可或缺的、独立的和信息丰富的指标。使用分层线性模型,我们确定了这些指标的相关亚组,并确定它们与微生物表型的关联性令人惊讶。这项工作可以作为一个垫脚石,编目生物相关的拓扑性质的网络和更好的建模的表型。我们使用的方法也可以应用于其他学科的网络。

英文摘要:

Understanding the dependence and interplay between architecture and function in biological networks has great relevance to disease progression, biological fabrication and biological systems in general. We propose methods to assess the association of various microbe characteristics and phenotypes with the topology of their networks. We adopt an automated approach to characterize metabolic networks of 32 microbial species using 11 topological metrics from complex networks. Clustering allows us to extract the indispensable, independent and informative metrics. Using hierarchical linear modeling, we identify relevant subgroups of these metrics and establish that they associate with microbial phenotypes surprisingly well. This work can serve as a stepping stone to cataloging biologically relevant topological properties of networks and towards better modeling of phenotypes. The methods we use can also be applied to networks from other disciplines.
