Diagnostic and Prognostic Value of miR-1287 in Colorectal Cancer.

INTRODUCTION:MicroRNAs are non-coding RNAs that regulate the gene expression at post-transcriptional level. This futuristic study characterized the contribution of miR-1287 to the colorectal cancer (CRC) tumorigenesis. METHODS:The real-time reverse transcription-polymerase chain reaction was used to examine miR-1287 expression levels, prospectively in 40 pairs of CRC tissue samples and adjacent noncancerous tissues (>2 cm from cancer tissue). RESULTS:No significant relationship was found between miR-1287 expression levels and clinicopathological features. Showing significant changes overall, MiR-1287 was significantly upregulated in the group of CRC samples compared with matched noncancerous tissue samples. A receiver operating characteristic (ROC) curve also showed ROC area (AROC) of 34 % with 1.0 and 0.02 sensitivity and specificity, respectively. Expression of miR-1287, with a value of 0.34, P value = 1.98, and P > 0.05, revealed that this microRNA has a low sensitivity and specificity to be regarded as a tumor marker. CONCLUSIONS:With regard to recent increased rate of CRC in the world, the present study may be a contribution, though very small, in the diagnosis and consequently in the treatment of CRC patients.
