Abstract：Objectives To investigate the expressions of miR-101 and COX-2 in colorectal cancer. Methods Thirty-twocolorectal cancer specimens and paired paracancer tissues were collected for assessment of miR-101 and COX-2 expressions by real-time quantitative PCR. Thecorrelation between miR-101 and COX-2 , as well as their correlations with the pathologywere analyzed. Results The expression level of miR-101 and COX-2 mRNA in the cancer tissues was significant difference between the cancer and para-cancer tissues (P < 0. 01). Also, miR-101 expression was negatively correlated with COX-2 mRNA expression (r = -0.373 5, P < 0.01). Furthermore,miR-101 expression was significantlydecreased along with the deterioration of tumor differentiation grade(P < 0.05). Compared with which in Dukes A ~ B stage, COX-2 expression was overexpressed and miR-101 was down-regulatedin colorectal cancer tissue inDukes C ~ Dstage , butnosignificant difference was found (P > 0.05). Conclusion Down-regulated miR-101 expression andparallel COX-2 overexpression hasbeen linked to colorectal cancer. miR-101 and COX-2might be thepotentialdiagnostic markers and therapeutic targets.
