Description:
Recurrent chromosomal rearrangements have not been well characterized in common carcinomas. We used a bioinformatics approach to discover candidate oncogenic chromosomal aberrations on the basis of outlier gene expression. Two ETS transcription factors, ERG and ETV1, were identified as outliers in prostate cancer. We identified recurrent gene fusions of the 5' untranslated region of TMPRSS2 to ERG or ETV1 in prostate cancer tissues with outlier expression. By using fluorescence in situ hybridization, we demonstrated that 23 of 29 prostate cancer samples harbor rearrangements in ERG or ETV1. Cell line experiments suggest that the androgen-responsive promoter elements of TMPRSS2 mediate the overexpression of ETS family members in prostate cancer. These results have implications in the development of carcinomas and the molecular diagnosis and treatment of prostate cancer.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tomlins, Scott A -- Rhodes, Daniel R -- Perner, Sven -- Dhanasekaran, Saravana M -- Mehra, Rohit -- Sun, Xiao-Wei -- Varambally, Sooryanarayana -- Cao, Xuhong -- Tchinda, Joelle -- Kuefer, Rainer -- Lee, Charles -- Montie, James E -- Shah, Rajal B -- Pienta, Kenneth J -- Rubin, Mark A -- Chinnaiyan, Arul M -- 5P30 CA46592/CA/NCI NIH HHS/ -- P50CA69568/CA/NCI NIH HHS/ -- R01 CA97063/CA/NCI NIH HHS/ -- R01AG21404/AG/NIA NIH HHS/ -- UO1 CA111275-01/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2005 Oct 28;310(5748):644-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pathology, University of Michigan Medical School, 1301 Catherine Street, Ann Arbor, MI 48109-0602, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16254181" target="_blank"〉PubMed〈/a〉
