With six HUVEC (human umbilical vein endothelial cells) samples hybridized on two-channel cDNA arrays and six HUVEC samples on Affymetrix arrays, 64 possible combinations of a three-step normalization procedure were investigated to search for the best normalization method, which was selected, based on two criteria measuring the extent to which expression profiles of biological samples of the same cell type arrayed on two platforms were indistinguishable. Next, three discriminative gene lists between the large vessel and the microvascular endothelial cells were achieved by SAM (significant analysis of microarrays), PAM (prediction analysis for microarrays), and a combination of SAM and PAM lists. The final discriminative gene list was selected by SVM (support vector machine). Based on this discriminative gene list, SVM classification analysis with best tuning parameters and 10,000 times of validations showed that BOEC were far from large vessel cells, they either formed their own class, or fell into the microvascular class. Based on all the common genes between the two platforms, SVM analysis further confirmed this conclusion.<\/jats:p>","DOI":"10.1142\/s0219720007002989","type":"journal-article","created":{"date-parts":[[2007,9,3]],"date-time":"2007-09-03T11:29:33Z","timestamp":1188818973000},"page":"875-893","source":"Crossref","is-referenced-by-count":13,"title":["A PRACTICAL QUESTION BASED ON CROSS-PLATFORM MICROARRAY DATA NORMALIZATION: ARE BOEC MORE LIKE LARGE VESSEL OR MICROVASCULAR ENDOTHELIAL CELLS OR NEITHER OF THEM?"],"prefix":"10.1142","volume":"05","author":[{"given":"AIXIANG","family":"JIANG","sequence":"first","affiliation":[{"name":"Division of Cancer Biostatistics, Department of Biostatistics, Vanderbilt University, Nashville, TN 37232, USA"}]},{"given":"WEI","family":"PAN","sequence":"additional","affiliation":[{"name":"Division of Biostatistics, School of Public Health, University of Minnesota, Minneapolis, MN 55455, USA"}]},{"given":"LIMING C.","family":"MILBAUER","sequence":"additional","affiliation":[{"name":"Vascular Biology Centre and Division of Hematology-Oncology-Transplantation, University of Minnesota, Minneapolis, MN 55455, USA"}]},{"given":"YU","family":"SHYR","sequence":"additional","affiliation":[{"name":"Division of Cancer Biostatistics, Department of Biostatistics, Vanderbilt University, Nashville, TN 37232, USA"},{"name":"Department of Statistics, National Cheng Kung University, Tainan, Taiwan"}]},{"given":"ROBERT P.","family":"HEBBEL","sequence":"additional","affiliation":[{"name":"Vascular Biology Centre and Division of Hematology-Oncology-Transplantation, University of Minnesota Minneapolis, MN 55455, USA"}]}],"member":"219","published-online":{"date-parts":[[2011,11,21]]},"reference":[{"key":"rf1","doi-asserted-by":"publisher","DOI":"10.1172\/JCI8071"},{"key":"rf2","doi-asserted-by":"publisher","DOI":"10.1182\/blood.V99.2.457"},{"key":"rf3","first-page":"26A","volume":"106","author":"Hebbel R.
