Data integration is necessary to cope with an ever increasing amount of data, to cross\u2010validate noisy data sets, and to gain broad interdisciplinary views of large biological data sets. New Internet resources may help researchers to combine data sets across different gene expression platforms. However, noise and disparities in experimental protocols strongly limit data integration. A detailed review of four selected studies reveals how some of these limitations may be circumvented and illustrates what can be achieved through data integration.<\/jats:p>","DOI":"10.1016\/s0014-5793(03)00522-2","type":"journal-article","created":{"date-parts":[[2003,5,19]],"date-time":"2003-05-19T17:32:55Z","timestamp":1053365575000},"page":"98-102","source":"Crossref","is-referenced-by-count":28,"title":["Integration and cross\u2010validation of high\u2010throughput gene expression data: comparing heterogeneous data sets"],"prefix":"10.1002","volume":"546","author":[{"given":"Vincent","family":"Detours","sequence":"first","affiliation":[]},{"given":"Jacques E.","family":"Dumont","sequence":"additional","affiliation":[]},{"given":"Hugues","family":"Bersini","sequence":"additional","affiliation":[]},{"given":"Carine","family":"Maenhaut","sequence":"additional","affiliation":[]}],"member":"311","published-online":{"date-parts":[[2003,5,17]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1126\/science.270.5235.484"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1126\/science.270.5235.467"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1038\/nbt1296-1675"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1210\/endo.143.6.8865"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1038\/ng1042"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/S1369-5274(02)00322-3"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0264-410X(01)00319-X"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1038\/ng1038"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.1038\/ng1032"},{"key":"e_1_2_7_11_1","doi-asserted-by":"publisher","DOI":"10.1038\/ng1033"},{"key":"e_1_2_7_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/S1097-2765(02)00531-2"},{"key":"e_1_2_7_13_1","first-page":"4427","volume":"62","author":"Rhodes D.R.","year":"2002","journal-title":"Cancer Res."},{"key":"e_1_2_7_14_1","first-page":"34","volume":"16","author":"Kling J.","year":"2002","journal-title":"Scientist"},{"key":"e_1_2_7_15_1","first-page":"16","volume":"16","author":"Fogarty M.","year":"2002","journal-title":"Scientist"},{"key":"e_1_2_7_16_1","unstructured":"DeFrancesco L.
