Thus, identifying recurrent gene rearrangements in common epithelial tumors may have profound implications CROSS REFERENCE TO RELATED for cancer drug discovery efforts as well as patient treatment. APPLICATIONS 0001. This application claims priority to U.S. provisional SUMMARY OF THE INVENTION applications 61/143,598, filed Jan. 9, 2009 and 61/187,776, 0006. The present invention relates to compositions and filed Jun. 17, 2009, each of which is herein incorporated by methods for cancer diagnosis, researchand therapy, including reference in its entirety. but not limited to, cancer markers. In particular, the present invention relates to recurrent gene fusions as diagnostic GOVERNMENT SUPPORT markers and clinical targets for cancer (e.g., prostate cancer). 0002 This invention was made with government support 0007 For example, in some embodiments, the present undergrant numbers CA069568, CA 111275 awarded by the invention provides a method for identifying prostate cancer in National Institutes of Health and grant number W81XWH a patient comprising: providing a sample from the patient; 08-1-0031 awarded by the Army. The government has certain and detecting the presence or absence in the sample of a gene rights in the invention. fusion having a 5" portion from a transcriptional regulatory region of an SLC45A3 gene and a 3' portion from an ELK4 FIELD OF THE INVENTION gene, wherein detecting the presence in the sample of the gene fusion identifies prostate cancer in the patient. In some 0003. The present invention relates to compositions and embodiments, the transcriptional regulatory region of the methods for cancer diagnosis, research and therapy, including SLC45A3 gene comprises a promoter region of the SLC45A3 but not limited to, cancer markers. In particular, the present gene. In some embodiments, the detecting comprises detect invention relates to recurrent gene fusions as diagnostic ing chimeric mRNA transcripts having a 5' RNA portion markers and clinical targets for cancer (e.g., prostate cancer). transcribed from the transcriptional regulatory region of the SLC45A3 gene and a 3' RNA portion transcribed from the BACKGROUND OF THE INVENTION ELK4 gene. In some embodiments, the gene fusion is a read 0004. A central aim in cancer research is to identify altered through transcript. In some embodiments, the sample is tis genes that are causally implicated in oncogenesis. Several Sue, blood, plasma, serum, urine, urine Supernatant, urine cell types of Somatic mutations have been identified including pellet, semen, prostatic secretions or prostate cells.
