ERG protein expression was limited to areas of TMPRSS2-ERG mRNA expression, but did not identify all of them.    ///    " PCA3 and TMPRSS2-ERG are commonly overexpressed biomarkers in prostate cancer, but reports have emerged demonstrating altered expression also in areas outside the tumour foci in cancerous prostates. "    ///    TMPRSS2-ERG mRNAs were detected in three patients and in 15 tissue samples in total.     ///    "ERG protein expression was limited to areas of TMPRSS2-ERG mRNA expression, but did not identify all of them. "    ///    "TMPRSS2-ERG expression was detected in carcinoma foci, regions next to them, and in samples not adjacent to carcinoma foci. "    ///    "Altered PCA3 and TMPRSS2-ERG expression in histologically benign regions of cancerous prostates: a systematic, quantitative mRNA analysis in five prostates.. "    ///    "Our aim was to measure PCA3 and TMPRSS2-ERG expression systematically in all regions of prostate cross-sections, matching the data to corresponding tissue morphology. "    ///    TMPRSS2-ERG and PCA3 mRNA levels were measured with quantitative reverse-transcription PCR assays in 270 samples from cross-sections of five radical prostatectomy specimens.
