MicroRNA-183-5p: A New Potential Marker for Prostate Cancer.

The microRNA (miR)-183-5p is expressed at high level in the majority of cancer. The purpose of present study was to investigate the role of oncogenic miR-183-5p in prostate cancer (PCa) as biomarker. We carried out our experiment in 50 prostate cancer patients and 40 patients of benign prostatic hyperplasia (BPH) and 40 adjacent controls tissue. The expression of miR-183-5p was evaluated through reverse transcription qualitative polymerase chain reaction. We found that the expression of miR-183-5p in PCa tissue was significantly up regulated as compared to BPH patients and adjacent normal tissues as control. Additionally, miR-183 expression was correlated with higher prostate-specific antigen, higher Gleason Score and metastatic condition. A receiver operating characteristic curve analysis revealed that miR-183-5p distinguished PCa patients from BPH patients and also from control. In conclusion, our data suggest that oncogenic miR-183-5p may be useful as a new tissue specific diagnostic biomarker in prostate cancer.
