适应性基因调控网络

Adaptive gene regulatory networks

Franck Stauffer, Johannes Berg

摘要:

基因之间的调控相互作用显示出大量的跨物种变异性,即使潜在的功能是保守的:有许多方法可以实现相同的功能。在这里,我们调查的能力,调控网络重现给定的表达水平在一个简单的模型中的基因调控。我们发现一个指数级大的调控网络空间与一组给定的表达水平兼容,从而产生了广泛的网络熵。调控网络的典型实现被发现共享一个偏向对称的相互作用,在符合经验证据。

英文摘要:

Regulatory interactions between genes show a large amount of cross-species variability, even when the underlying functions are conserved: There are many ways to achieve the same function. Here we investigate the ability of regulatory networks to reproduce given expression levels within a simple model of gene regulation. We find an exponentially large space of regulatory networks compatible with a given set of expression levels, giving rise to an extensive entropy of networks. Typical realisations of regulatory networks are found to share a bias towards symmetric interactions, in line with empirical evidence.
