生物学的一个挑战是了解细胞中复杂的分子网络如何执行复杂的调节功能。在这里,我们探讨了将网络结构与生物功能联系起来的共同原则和一般原则,这些原则限制了进化可以收敛于完成给定细胞任务的设计解决方案。我们描述了基于抽象架构和功能的网络分类方法,而不是基于网络的特定分子成分。对于任何共同的调控任务,我们能定义所有可能的分子解决方案的空间吗?这种反向方法可能最终允许组装核心分子算法的设计表,可以作为构建合成网络和调节疾病网络的指南。
A challenge in biology is to understand how complex molecular networks in the cell execute sophisticated regulatory functions. Here we explore the idea that there are common and general principles that link network structures to biological functions, principles that constrain the design solutions that evolution can converge upon for accomplishing a given cellular task. We describe approaches for classifying networks based on abstract architectures and functions, rather than on the specific molecular components of the networks. For any common regulatory task, can we define the space of all possible molecular solutions? Such inverse approaches might ultimately allow the assembly of a design table of core molecular algorithms that could serve as a guide for building synthetic networks and modulating disease networks.
