  • Title: MOfinder: a novel algorithm for detecting overlapping modules from protein-protein interaction network.
    Author: Yu Q, Li GH, Huang JF.
    Journal: J Biomed Biotechnol; 2012; 2012():103702. PubMed ID: 22500072.
    Abstract:
    Since organism development and many critical cell biology processes are organized in modular patterns, many algorithms have been proposed to detect modules. In this study, a new method, MOfinder, was developed to detect overlapping modules in a protein-protein interaction (PPI) network. We demonstrate that our method is more accurate than other 5 methods. Then, we applied MOfinder to yeast and human PPI network and explored the overlapping information. Using the overlapping modules of human PPI network, we constructed the module-module communication network. Functional annotation showed that the immune-related and cancer-related proteins were always together and present in the same modules, which offer some clues for immune therapy for cancer. Our study around overlapping modules suggests a new perspective on the analysis of PPI network and improves our understanding of disease.
