However, separating tissue-specific features from across cancer signatures has proven to be challenging. One of the often-observed properties of the mutational landscape of cancer is the mutual exclusivity of cancer driving mutations. Even though studies based on individual cancer types suggested that mutually exclusive pairs often share the same functional pathway, the relationship between across cancer mutual exclusivity and functional connectivity has not been previously investigated.<\/jats:p>\n               <jats:p>Results: We introduce a classification of mutual exclusivity into three basic classes: within tissue type exclusivity, across tissue type exclusivity and between tissue type exclusivity. We then combined across-cancer mutual exclusivity with interactions data to uncover pan-cancer dysregulated pathways. Our new method, Mutual Exclusivity Module Cover (MEMCover) not only identified previously known Pan-Cancer dysregulated subnetworks but also novel subnetworks whose across cancer role has not been appreciated well before. In addition, we demonstrate the existence of mutual exclusivity hubs, putatively corresponding to cancer drivers with strong growth advantages. Finally, we show that while mutually exclusive pairs within or across cancer types are predominantly functionally interacting, the pairs in between cancer mutual exclusivity class are more often disconnected in functional networks.<\/jats:p>\n               <jats:p>Contact: \u00a0przytyck@ncbi.nlm.nih.gov<\/jats:p>\n               <jats:p>Supplementary information: \u00a0Supplementary data are available at Bioinformatics online.<\/jats:p>","DOI":"10.1093\/bioinformatics\/btv247","type":"journal-article","created":{"date-parts":[[2015,6,13]],"date-time":"2015-06-13T17:12:36Z","timestamp":1434215556000},"page":"i284-i292","source":"Crossref","is-referenced-by-count":93,"title":["MEMCover: integrated analysis of mutual exclusivity and functional network reveals dysregulated pathways across multiple cancer types"],"prefix":"10.1093","volume":"31","author":[{"given":"Yoo-Ah","family":"Kim","sequence":"first","affiliation":[{"name":"National Center for Biotechnology Information, National Library of Medicine, National Institutes of Health, 8600 Rockville Pike, Bethesda, MD, 20894, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dong-Yeon","family":"Cho","sequence":"additional","affiliation":[{"name":"National Center for Biotechnology Information, National Library of Medicine, National Institutes of Health, 8600 Rockville Pike, Bethesda, MD, 20894, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Phuong","family":"Dao","sequence":"additional","affiliation":[{"name":"National Center for Biotechnology Information, National Library of Medicine, National Institutes of Health, 8600 Rockville Pike, Bethesda, MD, 20894, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Teresa M.","family":"Przytycka","sequence":"additional","affiliation":[{"name":"National Center for Biotechnology Information, National Library of Medicine, National Institutes of Health, 8600 Rockville Pike, Bethesda, MD, 20894, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2015,6,10]]},"reference":[{"key":"2023020115414885900_btv247-B1","doi-asserted-by":"crossref","first-page":"1061","DOI":"10.1038\/nature07385","article-title":"Comprehensive genomic characterization defines human glioblastoma genes and core pathways","volume":"455","author":"Cancer Genome Atlas Research, N","year":"2008","journal-title":"Nature"},{"key":"2023020115414885900_btv247-B2","doi-asserted-by":"crossref","first-page":"519","DOI":"10.1038\/nature11404","article-title":"Comprehensive genomic characterization of squamous cell lung cancers","volume":"489","author":"Cancer Genome Atlas Research, N","year":"2012","journal-title":"Nature"},{"key":"2023020115414885900_btv247-B3","doi-asserted-by":"crossref","first-page":"43","DOI":"10.1038\/nature12222","article-title":"Comprehensive molecular characterization of clear cell renal cell carcinoma","volume":"499","author":"Cancer Genome Atlas Research, N","year":"2013","journal-title":"Nature"},{"key":"2023020115414885900_btv247-B4","doi-asserted-by":"crossref","first-page":"1113","DOI":"10.1038\/ng.2764","article-title":"The cancer genome atlas pan-cancer analysis project","volume":"45","author":"Cancer Genome Atlas Research, N. et al.","year":"2013","journal-title":"Nat.
