THERMODYNAMIC MEASURES ON PROTEIN-PROTEIN INTERACTION NETWORKS FOR CANCER THERAPY

摘要

A method to select a protein target for therapeutic application includes accessing genomic information and protein-protein interaction (PPI) data, computing a thermodynamic measure for each protein node within the network of protein nodes, generating an energy landscape data corresponding to the network of protein nodes and the thermodynamic measure, generating a PPI subnetwork by applying a topological filtration to the energy landscape data of the PPI data, computing a first Betti number for the PPI subnetwork, sequentially removing a protein node(s) from the PPI subnetwork while replacing the previously removed node(s), computing a new Betti number for the PPI subnetwork with the protein node(s) removed, computing a change between the Betti numbers, and determining, based on the change between the Beti numbers, a most significant protein target within the PPI subnetwork.
