Genome-wide characterization of gene expression variations and DNA copy number changes in prostate cancer cell lines

@article{citeulike:1927644, abstract = {The aim of this study was to characterize gene expression and DNA copy number profiles in androgen sensitive (AS) and androgen insensitive (AI) prostate cancer cell lines on a genome-wide scale.Gene expression profiles and DNA copy number changes were examined using DNA microarrays in eight commonly used prostate cancer cell lines. Chromosomal regions with DNA copy number changes were identified using cluster along chromosome (CLAC).There were discrete differences in gene expression patterns between AS and AI cells that were not limited to androgen-responsive genes. AI cells displayed more DNA copy number changes, especially amplifications, than AS cells. The gene expression profiles of cell lines showed limited similarities to prostate tumors harvested at surgery.AS and AI cell lines are different in their transcriptional programs and degree of DNA copy number alterations. This dataset provides a context for the use of prostate cancer cell lines as models for clinical cancers. {\copyright} 2004 Wiley-Liss, Inc.}, address = {Department of Urology, Stanford University School of Medicine, Stanford, California; Department of Pathology, Stanford University School of Medicine, Stanford, California; Department of Statistics, Stanford, California; Department of Health Research and Policy, Stanford University School of Medicine, Stanford, California}, author = {Zhao, Hongjuan and Kim, Young and Wang, Pei and Lapointe, Jacques and Tibshirani, Rob and Pollack, Jonathan R. and Brooks, James D. }, citeulike-article-id = {1927644}, doi = {10.1002/pros.20158}, journal = {The Prostate}, keywords = {cancer, cell-lines, cnv, prostate}, number = {2}, pages = {187--197}, posted-at = {2007-11-16 19:24:13}, priority = {2}, title = {Genome-wide characterization of gene expression variations and DNA copy number changes in prostate cancer cell lines}, url = {http://dx.doi.org/10.1002/pros.20158}, volume = {63}, year = {2005} }
