To investigate the expression alteration of miR5-886-p in bladder tumors and evaluating its expression level as a potential biomarker in this type of cancer.


Formalin-fixed paraffin-embedded (FFPE) samples of bladder tumors belonging to 70 patients whom had been referred to the Shahid Labbafi-Nejad medical center were obtained from the archival collection of pathology department. After RNA extraction and cDNA synthesis, expression levels of miR5-886-p were quantified by a real-time reverse transcription polymerase chain reaction (RT-PCR) approach.


Our data revealed a significant upregulation (~3 times) of miR5-886-p in high grade bladder tumors, compared to the low grade ones (P < .05). Moreover, its expression level could significantly discriminate noninvasive (Ta, T1) from invasive (T-2T4) tumor stages.


Our data suggests a potential role for miR5-886-p in progression of bladder cancer.
