Despite their prevalence, it is unclear what quantitative role they play in either initiation or progression of the disease. Using a lentiviral transduction and dissociated cell prostate regeneration approach, we find that acutely increased expression of ETS proteins in adult murine prostate epithelial cells is sufficient to induce the formation of epithelial hyperplasia and focal prostatic intraepithelial neoplasia (PIN) lesions, but not progression to carcinoma. However, combined expression of ERG with additional genetic alternations associated with human prostate cancer can lead to aggressive disease. Although ERG overexpression does not cooperate with loss of the tumor suppressor p53, it does collaborate with alterations in PI3K signaling, such as Pten knockdown or AKT up-regulation, to produce a well-differentiated adenocarcinoma. Most striking is our finding that overexpression of androgen receptor (AR) does not give rise to any hyperplastic lesions, but when combined with high levels of ERG, it promotes the development of a more poorly differentiated, invasive adenocarcinoma. These findings suggest that in human prostate cancer, the most potent function of ETS gene fusions may be to synergize with alternative genetic events and provide different pathways for carcinoma production and invasive behavior. Our results provide direct evidence for selective cooperating events in ERG-induced prostate tumorigenesis and offer a rational basis for combined therapeutic interventions against multiple oncogenic pathways in prostate cancer.<\/jats:p>","DOI":"10.1073\/pnas.0905931106","type":"journal-article","created":{"date-parts":[[2009,7,10]],"date-time":"2009-07-10T20:34:27Z","timestamp":1247258067000},"page":"12465-12470","update-policy":"https:\/\/doi.org\/10.1073\/pnas.cm10313","source":"Crossref","is-referenced-by-count":171,"title":["ETS family transcription factors collaborate with alternative signaling pathways to induce carcinoma from adult murine prostate cells"],"prefix":"10.1073","volume":"106","author":[{"given":"Yang","family":"Zong","sequence":"first","affiliation":[{"name":"Howard Hughes Medical Institute,"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Li","family":"Xin","sequence":"additional","affiliation":[{"name":"Department of Microbiology, Immunology, and Molecular Genetics,"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrew S.","family":"Goldstein","sequence":"additional","affiliation":[{"name":"Molecular Biology Institute,"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Devon A.","family":"Lawson","sequence":"additional","affiliation":[{"name":"Department of Microbiology, Immunology, and Molecular Genetics,"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael A.","family":"Teitell","sequence":"additional","affiliation":[{"name":"Molecular Biology Institute,"},{"name":"Department of Pathology and Laboratory Medicine, and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Owen N.","family":"Witte","sequence":"additional","affiliation":[{"name":"Howard Hughes Medical Institute,"},{"name":"Department of Microbiology, Immunology, and Molecular Genetics,"},{"name":"Molecular Biology Institute,"},{"name":"Department of Molecular and Medical Pharmacology, David Geffen School of Medicine, University of California, Los Angeles, CA 90095"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"341","published-online":{"date-parts":[[2009,7,28]]},"reference":[{"key":"e_1_3_3_1_2","doi-asserted-by":"publisher","DOI":"10.1016\/0168-9525(93)90209-Z"},{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1038\/nm1087"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1101\/gad.819500"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1126\/science.278.5340.1059"},{"key":"e_1_3_3_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.molmed.2006.09.005"},{"key":"e_1_3_3_6_2","doi-asserted-by":"publisher","DOI":"10.1126\/science.1117679"},{"key":"e_1_3_3_7_2","doi-asserted-by":"publisher","DOI":"10.1158\/0008-5472.CAN-06-0168"},{"key":"e_1_3_3_8_2","doi-asserted-by":"publisher","DOI":"10.1038\/nature06024"},{"key":"e_1_3_3_9_2","doi-asserted-by":"publisher","DOI":"10.1158\/0008-5472.CAN-07-5352"},{"key":"e_1_3_3_10_2","doi-asserted-by":"publisher","DOI":"10.1158\/0008-5472.CAN-06-1871"},{"key":"e_1_3_3_11_2","doi-asserted-by":"publisher","DOI":"10.1038\/nrc2402"},{"key":"e_1_3_3_12_2","doi-asserted-by":"publisher","DOI":"10.1158\/0008-5472.CAN-06-1482"},{"key":"e_1_3_3_13_2","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.0711711105"},{"key":"e_1_3_3_14_2","doi-asserted-by":"publisher","DOI":"10.1210\/endo.141.12.7837"},{"key":"e_1_3_3_15_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0925-4773(00)00551-7"},{"key":"e_1_3_3_16_2","doi-asserted-by":"publisher","DOI":"10.1593\/neo.07822"},{"key":"e_1_3_3_17_2","doi-asserted-by":"publisher","DOI":"10.1038\/nature07738"},{"key":"e_1_3_3_18_2","doi-asserted-by":"publisher","DOI":"10.1038\/ng.371"},{"key":"e_1_3_3_19_2","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.1734139100"},{"key":"e_1_3_3_20_2","doi-asserted-by":"publisher","DOI":"10.1002\/path.2154"},{"key":"e_1_3_3_21_2","doi-asserted-by":"publisher","DOI":"10.1038\/nature04496"},{"key":"e_1_3_3_22_2","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.0609684104"},{"key":"e_1_3_3_23_2","doi-asserted-by":"publisher","DOI":"10.1038\/onc.2008.183"},{"key":"e_1_3_3_24_2","doi-asserted-by":"publisher","DOI":"10.1074\/jbc.M010208200"},{"key":"e_1_3_3_25_2","first-page":"1924","article-title":"Alterations of p53 are common in early stage prostate cancer","volume":"10","author":"Downing SR","year":"2003","unstructured":"SR Downing, PJ Russell, P Jackson, Alterations of p53 are common in early stage prostate cancer.
