RESUMO
Objective To investigate the expression and significance of miR?135a?5p in endometrial carcinoma and to correlate expression levels with clinicopathological features. Methods Fifty five endometrial carcinoma samples and thirty normal endometrial tissue samples were surgically obtained,and the expression of miR?135a?5p was quantitated by real?time polymerase chain reaction. The relationship between the expression level of miR?135a?5p and clinicopathological data of individual patients was analyzed. Results The expression of miR?135a?5p was lower in the endo?metrial carcinoma group than in the normal endometrial group(P=0.021),and correlated significantly with the histologic grade of the endometrial neoplasm(P=0.008). Conclusion The expression of miR?135a?5p is lower in endometrial carcinoma than in normal endometrial tissue. In en?dometrial carcinoma,the miR?135a?5p expression status has a statistically significant relationship with the histological characteristics of the tumor.
