A relatively unknown procedure that can be used is the intersection\u2013union test (IUT). However, two disadvantages of the IUT are that it is conservative and it conveys only the information of the least differing target tissue\u2013other tissue pair.<\/jats:p>\n               <jats:p>Results: We propose a Bayesian procedure that quantifies how much evidence there is in the overall expression profile for selective over-expression. In a small simulation study, it is shown that the proposed method outperforms the IUT when it comes to finding selectively expressed genes. An application to publicly available data consisting of 22 tissues shows that the Bayesian method indeed selects genes with functions that reflect the specific tissue functions. The proposed method can also be used to find genes that are underexpressed in a particular tissue.<\/jats:p>\n               <jats:p>Availability: Both MATLAB and R code that implement the IUT and the Bayesian procedure in an efficient way, can be downloaded at http:\/\/ppw.kuleuven.be\/okp\/software\/BayesianIUT\/.<\/jats:p>\n               <jats:p>Contact: \u00a0katrijn.vandeun@psy.kuleuven.be<\/jats:p>","DOI":"10.1093\/bioinformatics\/btp439","type":"journal-article","created":{"date-parts":[[2009,8,12]],"date-time":"2009-08-12T03:55:08Z","timestamp":1250049308000},"page":"2588-2594","source":"Crossref","is-referenced-by-count":14,"title":["Testing the hypothesis of tissue selectivity: the intersection\u2013union test and a Bayesian approach"],"prefix":"10.1093","volume":"25","author":[{"given":"K.","family":"Van Deun","sequence":"first","affiliation":[{"name":"1 Center for Computational Systems Biology SymBioSys, Katholieke Universiteit Leuven, 3000 Leuven, Belgium, 2Department of Methodology and Statistics, University of Utrecht, 3508 TC Utrecht, The Netherlands and 3Gene Expression Unit, Katholieke Universiteit Leuven, 3000 Leuven, Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"H.","family":"Hoijtink","sequence":"additional","affiliation":[{"name":"1 Center for Computational Systems Biology SymBioSys, Katholieke Universiteit Leuven, 3000 Leuven, Belgium, 2Department of Methodology and Statistics, University of Utrecht, 3508 TC Utrecht, The Netherlands and 3Gene Expression Unit, Katholieke Universiteit Leuven, 3000 Leuven, Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"L.","family":"Thorrez","sequence":"additional","affiliation":[{"name":"1 Center for Computational Systems Biology SymBioSys, Katholieke Universiteit Leuven, 3000 Leuven, Belgium, 2Department of Methodology and Statistics, University of Utrecht, 3508 TC Utrecht, The Netherlands and 3Gene Expression Unit, Katholieke Universiteit Leuven, 3000 Leuven, Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"L.","family":"Van Lommel","sequence":"additional","affiliation":[{"name":"1 Center for Computational Systems Biology SymBioSys, Katholieke Universiteit Leuven, 3000 Leuven, Belgium, 2Department of Methodology and Statistics, University of Utrecht, 3508 TC Utrecht, The Netherlands and 3Gene Expression Unit, Katholieke Universiteit Leuven, 3000 Leuven, Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"F.","family":"Schuit","sequence":"additional","affiliation":[{"name":"1 Center for Computational Systems Biology SymBioSys, Katholieke Universiteit Leuven, 3000 Leuven, Belgium, 2Department of Methodology and Statistics, University of Utrecht, 3508 TC Utrecht, The Netherlands and 3Gene Expression Unit, Katholieke Universiteit Leuven, 3000 Leuven, Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"I.","family":"Van Mechelen","sequence":"additional","affiliation":[{"name":"1 Center for Computational Systems Biology SymBioSys, Katholieke Universiteit Leuven, 3000 Leuven, Belgium, 2Department of Methodology and Statistics, University of Utrecht, 3508 TC Utrecht, The Netherlands and 3Gene Expression Unit, Katholieke Universiteit Leuven, 3000 Leuven, Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2009,8,11]]},"reference":[{"key":"2023013112123312500_B1","doi-asserted-by":"crossref","first-page":"55","DOI":"10.1038\/nrg1749","article-title":"Microarray data analysis: from disarray to consolidation and consensus","volume":"7","author":"Allison","year":"2006","journal-title":"Nat.
