Prostate cancer is a leading cause of tumor mortality. To characterize the underlying molecular mechanisms, we have compared the microRNA (miRNA) profile of primary prostate cancers and noncancer prostate tissues using deep sequencing. MiRNAs are small noncoding RNAs of 21 to 25 nucleotides that regulate gene expression through the inhibition of protein(More)
MicroRNAs (miRNAs) are small RNA molecules that regulate gene expression via posttranscriptional inhibition of protein synthesis. They play a vital role in tumorigenesis. To characterize the diagnostic potential of miRNAs in prostate cancer, a leading cause of cancer mortality, we performed screening of miRNA expression profiles. We used commercially(More)
OBJECTIVE To evaluate 15-year experience with patients treated with transurethral resection (TUR) of a bladder tumor (TURBT) followed by radiochemotherapy (RCT) or radiation (RT) and to describe the association of different parameters with clinical outcome. PATIENTS AND METHODS Bladder cancer patients (473) who underwent TURBT and RCT or RT with curative(More)
A significant proportion of the human genome is comprised of human endogenous retroviruses (HERVs). HERV transcripts are found in every human tissue. Expression of proviruses of the HERV-K(HML-2) family has been associated with development of human tumors, in particular germ cell tumors (GCT). Very little is known about transcriptional activity of(More)
In primary prostate cancer (PCa), a major cause of cancer-related death in men, the expression of various microRNAs (miRNAs) is deregulated. We previously detected several miRNAs, for example, miR-24 and miR-22, as significantly downregulated in PCa (Szczyrba et al., Mol Cancer Res 2010;8:529-38). An in silico search predicted that zinc finger protein 217(More)
PURPOSE We determine the sensitivity and specificity of cytokeratin 20 (CK-20) and mucin 7 (MUC7) gene expression in voided urine samples taken from patients with bladder tumor and from control groups to investigate putative, noninvasive urinary markers for bladder tumor detection and monitoring. MATERIALS AND METHODS Voided urine samples were collected(More)
In a multicenter study, we determined the expression profiles of 863 microRNAs by array analysis of 454 blood samples from human individuals with different cancers or noncancer diseases, and validated this 'miRNome' by quantitative real-time PCR. We detected consistently deregulated profiles for all tested diseases; pathway analysis confirmed disease(More)
Prostate cancer is a leading cause of cancer mortality in men. One of the distinct characteristics of prostate cancer is over-expression of the ERG proto-oncogene. The TMPRSS2-ERG gene fusion, the most common gene fusion, is found in approximately 50% of prostate cancer cases. We show that certain microRNAs are extensively deregulated in prostate cancer(More)
BACKGROUND This study evaluated the cytotoxic and antiproliferative efficacy of two well-characterized members of the Cecropin-family of antimicrobial peptides against bladder tumor cells and benign fibroblasts. METHODS The antiproliferative and cytotoxic potential of the Cecropins A and B was quantified by colorimetric WST-1-, BrdU- and LDH-assays in(More)
OBJECTIVES To retrospectively assess the outcome of patients with initial PSA of 20 ng/ml or higher undergoing radical prostatectomy (RP) for prostate cancer (pCA). METHODS Between January 1986 and June 2005, 275 patients with preoperative PSA> or =20 ng/ml underwent RP for pCA at our institution. Overall, disease-specific and biochemical progression-free(More)
