The reviewer's point identifies a division of labor rather than a gap in either approach: experiments establish which regulators act upstream and downstream of a signal, while models are needed to embed that information in an intracellular network and ask how a group of cells processes signals collaboratively. Network control frameworks illustrate how such intracellular information can be used to predict intervention targets, as shown for a leukemia signaling network and for the network controlling helper T cell differentiation.

Here we develop a novel network control framework that integrates the structural and functional information available for intracellular networks to predict control targets. Formulated in a logical dynamic scheme, our approach drives any initial state to the target state with 100% effectiveness and needs to be applied only transiently for the network to reach and stay in the desired state. We illustrate our method’s potential to find intervention targets for cancer treatment and cell differentiation by applying it to a leukemia signaling network and to the network controlling the differentiation of helper T cells. We find that the predicted control targets are effective in a broad dynamic framework. Moreover, several of the predicted interventions are supported by experiments.
