As proteins involved in common processes tend to be centralized in the same local area of protein\u2013protein interaction networks, here a novel framework has been developed to identify which areas of the networks are most relevant to a phenotype.<\/jats:p>\n               <jats:p>Results: These areas termed \u2018coherent modules\u2019 can be regarded as gene sets dynamically defined in the networks. Compared with previous analogous approaches, one critical feature of our method is the optimization of coherent modules for two distinct aspects balanced by tuning a parameter in the framework. First, we seek the low coupling between coherent modules and then maximize the intrinsic similarity within a module. The framework has good expansibility, with classical expression data analysis methods generalized as particular cases. This coherent module approach was applied to an oral cavity tumor dataset with 18 significant coherent modules identified, which could indicate the presence of lymph node metastasis. Further examination shows that most of the modules are responsible for comparatively independent biological processes. Our framework is helpful for the prognosis of tumors and offers a new perspective for tumor research.<\/jats:p>\n               <jats:p>Contact: \u00a0sunzhr@mail.tsinghua.edu.cn<\/jats:p>\n               <jats:p>Supplementary information: \u00a0Supplementary data are available at Bioinformatics online.<\/jats:p>","DOI":"10.1093\/bioinformatics\/btp057","type":"journal-article","created":{"date-parts":[[2009,1,31]],"date-time":"2009-01-31T01:14:58Z","timestamp":1233364498000},"page":"795-800","source":"Crossref","is-referenced-by-count":3,"title":["Exploring phenotype-associated modules in an oral cavity tumor using an integrated framework"],"prefix":"10.1093","volume":"25","author":[{"given":"Zhirong","family":"Sun","sequence":"first","affiliation":[{"name":"Institute of Bioinformatics and Systems Biology, MOE Key Laboratory of Bioinformatics, State Key Laboratory of Biomembrane and Membrane Biotechnology and Department of Biological Sciences and Biotechnology, Tsinghua University, Beijing, 100084, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jie","family":"Luo","sequence":"additional","affiliation":[{"name":"Institute of Bioinformatics and Systems Biology, MOE Key Laboratory of Bioinformatics, State Key Laboratory of Biomembrane and Membrane Biotechnology and Department of Biological Sciences and Biotechnology, Tsinghua University, Beijing, 100084, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yun","family":"Zhou","sequence":"additional","affiliation":[{"name":"Institute of Bioinformatics and Systems Biology, MOE Key Laboratory of Bioinformatics, State Key Laboratory of Biomembrane and Membrane Biotechnology and Department of Biological Sciences and Biotechnology, Tsinghua University, Beijing, 100084, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Junjie","family":"Luo","sequence":"additional","affiliation":[{"name":"Institute of Bioinformatics and Systems Biology, MOE Key Laboratory of Bioinformatics, State Key Laboratory of Biomembrane and Membrane Biotechnology and Department of Biological Sciences and Biotechnology, Tsinghua University, Beijing, 100084, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ke","family":"Liu","sequence":"additional","affiliation":[{"name":"Institute of Bioinformatics and Systems Biology, MOE Key Laboratory of Bioinformatics, State Key Laboratory of Biomembrane and Membrane Biotechnology and Department of Biological Sciences and Biotechnology, Tsinghua University, Beijing, 100084, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wenting","family":"Li","sequence":"additional","affiliation":[{"name":"Institute of Bioinformatics and Systems Biology, MOE Key Laboratory of Bioinformatics, State Key Laboratory of Biomembrane and Membrane Biotechnology and Department of Biological Sciences and Biotechnology, Tsinghua University, Beijing, 100084, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2009,1,29]]},"reference":[{"key":"2023051209124441100_B1","doi-asserted-by":"crossref","first-page":"433","DOI":"10.1038\/sj.leu.2402417","article-title":"The proteasome: a novel target for cancer chemotherapy","volume":"16","author":"Almond","year":"2002","journal-title":"Leukemia"},{"key":"2023051209124441100_B2","doi-asserted-by":"crossref","first-page":"D760","DOI":"10.1093\/nar\/gkl887","article-title":"NCBI GEO: mining tens of millions of expression profiles\u2013database and tools update","volume":"35","author":"Barrett","year":"2007","journal-title":"Nucleic Acids Res."},{"key":"2023051209124441100_B3","doi-asserted-by":"crossref","first-page":"2898","DOI":"10.1093\/bioinformatics\/bti440","article-title":"Differential network expression during drug and stress response","volume":"21","author":"Cabusora","year":"2005","journal-title":"Bioinformatics"},{"key":"2023051209124441100_B4","doi-asserted-by":"crossref","first-page":"2283","DOI":"10.1093\/bioinformatics\/btl370","article-title":"Detecting functional modules in the yeast protein-protein interaction network","volume":"22","author":"Chen","year":"2006","journal-title":"Bioinformatics"},{"key":"2023051209124441100_B5","doi-asserted-by":"crossref","first-page":"1507","DOI":"10.1111\/j.1349-7006.2008.00863.x","article-title":"Head and neck cancer in the betel quid chewing area: recent advances in molecular carcinogenesis","volume":"99","author":"Chen","year":"2008","journal-title":"Cancer Sci."},{"key":"2023051209124441100_B6","doi-asserted-by":"crossref","first-page":"140","DOI":"10.1038\/msb4100180","article-title":"Network-based classification of breast cancer metastasis","volume":"3","author":"Chuang","year":"2007","journal-title":"Mol.
