AI总结:

该研究通过构建最大的专家整理布尔基因调控网络模型库并进行元分析,揭示了GRNs具有更高的渠化性、冗余性、稳定动力学及特定网络模体富集等设计原理,为理解进化偏好提供了基础。

摘要:

基因调控网络(GRNs)在细胞决策中发挥着核心作用。因此,理解其结构以及结构如何影响其动力学构成了一个基本的生物学问题。GRNs 通常被建模为布尔网络,这种模型直观、易于描述,并且即使在数据稀疏的情况下也能给出定性结果。我们汇集了最大的由专家整理的布尔 GRN 模型库。对这一多样化模型集合的元分析揭示了若干设计原理。GRNs 表现出比预期更多的渠化(canalization)、冗余性和稳定动力学。此外,它们富含某些反复出现的网络模体(network motifs)。这提出了一个重要问题:为什么进化会偏爱这些设计机制。

英文摘要:

Gene regulatory networks (GRNs) play a central role in cellular decision-making. Understanding their structure and how it impacts their dynamics constitutes thus a fundamental biological question. GRNs are frequently modeled as Boolean networks, which are intuitive, simple to describe, and can yield qualitative results even when data is sparse. We assembled the largest repository of expert-curated Boolean GRN models. A meta-analysis of this diverse set of models reveals several design principles. GRNs exhibit more canalization, redundancy and stable dynamics than expected. Moreover, they are enriched for certain recurring network motifs. This raises the important question why evolution favors these design mechanisms.
