Recent advances in experimental biology have generated a wealth of molecular activity data, particularly from individual patient datasets. This study aims to develop an efficient pipeline for reverse-engineering regulatory networks using proteomic data from individual patients. By applying SCOUT algorithm and path-consistent method, a protein-protein interaction network is constructed and false interactions are further removed using a dynamic model of ordinary differential equations.
Recent advances in experimental biology studies have produced large amount of molecular activity data. In particular, individual patient data provide non-time series information for the molecular activities in disease conditions. The challenge is how to design effective algorithms to infer regulatory networks using the individual patient datasets and consequently address the issue of network symmetry. This work is aimed at developing an efficient pipeline to reverse-engineer regulatory networks based on the individual patient proteomic data. The first step uses the SCOUT algorithm to infer the pseudo-time trajectory of individual patients. Then the path-consistent method with part mutual information is used to construct a static network that contains the potential protein interactions. To address the issue of network symmetry in terms of undirected symmetric network, a dynamic model of ordinary differential equations is used to further remove false interactions to derive asymmetric networks. In this work a dataset from triple-negative breast cancer patients is used to develop a protein-protein interaction network with 15 proteins.
