Study of gene regulatory network based on graph

We presented a study method for gene regulatory network using graph theory. In this paper, we proposed the dynamics equations of regulatory network, and studied the measurement of regulatory influence of regulatory network. We also studied the modular approach of studying regulatory network and proposed a modular algorithm to do lossless decomposition of regulatory networks. Finally, an illustrative example was provided, and its results suggested that graph theory is an effective way for the analysis of regulatory network.
