Discriminating direct and indirect connectivities in biological networks

Abstract

We used a combination of computational and theoretical approaches coupled to synthetic biology experimentation in mammalian cells to study direct and indirect connectivities in biological networks. After subjecting benchmark circuits to a range of perturbations, we recovered the edge weights using nonparametric single-cell data resampling coupled with modular response analysis. We discovered that inferred weights of specific network edges undergo divergent shifts under differential perturbations, and that the particular behavior is topology dependent. Incorporating this insight in the analysis of high-throughput experiments may provide a sought-after solution to a longstanding reverse engineering problem.
