| Summary: | Background: Prostate cancer (PCa) is the most common causing cancer-related in death in men and lack of reliable diagnostic tool. MicroRNAs are small molecules single-stranded RNA that affecting protein expression at the level of translation and dysregulation can dramatically affect cell metabolism. However, the using of circulating miRNAs as diagnostic biomarkers for diagnosis of PCa is still unknown.
Methods: Ten patients with prostatic hyperplasia with high-level of PSA and 10 healthy controls were conducted in this study. The reverse transcription of miRNA based on quantitative polymerase chain reaction (qPCR) were used for evaluating the dysregulation of miRNA 30b-3p and using of ELISA to evaluate the level of prostate-specific antigen (PSA) and testosterone hormone.
Results: Circulating miRNA 30b-3p level was increased in patients with prostatic hyperplasia with higher level of PSA as compared with healthy controls. Also, the testosterone hormone was increased in those patients as compared with normal level of testosterone in healthy individuals.
Conclusion: The serum miRNA 30b-3p level increased in patients with hyperplasia in prostate and may be one of potential biomarker for diagnosis of PCa.
