In contrast with the results of Perner et al. Of 18 genes, 3 overlapped Figure 1 C , probability of detecting three common genes by chance is equal to 0. Demichelis are coinventors on a patent filed by The University of Michigan and The Brigham and Women’s Hospital covering the diagnostic and therapeutic fields for ETS fusions in prostate cancer. It has been suggested that ERG rearrangement may not be associated with an active fusion transcript with disease progression [ 23 ]. Several previous papers have addressed different aspects of this relationship. Share Facebook Twitter Pinterest.

Don’t see what you’re looking for? Frozen HNPC samples were obtained from men with localized and locally advanced prostate cancer who underwent radical prostatectomy as a monotherapy and were processed as previously described [ 4 ].
Additionally, we identified 78 paraffin-embedded tissue samples from patients who had undergone radical prostatectomies. Our results further support the idea first suggested by Yu et al. Indeed, we rrg that the median number of probes with DNA methylation was Using a recently described protocol [ 8 ], tissue cores at diameters of 0. PTEN losses exhibit heterogeneity in multifocal prostatic adenocarcinoma and are associated with higher Gleason grade.

J Natl Cancer Inst. To elucidate the role of ETS gene fusions in castration-resistant prostate cancer CRPCwe characterized the transcriptome of 54 CRPC tumor samples from men with locally advanced or metastatic disease.
All samples were deparaffinized and genomic DNA was isolated by phenol-chloroform extraction as we have done previously in reference 6. DNA methylation of promoter regions is a common event in prostate cancer, one of the most common cancers in men worldwide. In contrast to other family members, PFKFB3 has the highest kinase-phosphatase activity ratio, and up-regulation significantly promotes glycolysis [ 7 egr.
Androgen receptor regulates a distinct transcription program in androgen-independent prostate cancer. Our results demonstrate the usefulness of al-003 bead arrays, confirm that the method is robust using material obtained from archived samples and provide data that assessment of ERG promoter methylation may improve our ability to more accurately diagnose and detect prostate cancer.
For all experiments, error bars demonstrate SD across triplicate experiments. On the other hand, Perner et al. Molecular determinants of resistance to antiandrogen therapy. CpG island methylator phenotype in colorectal cancer. In 38 cases, only one core was available for the analysis. J Stat Comput Simul.
