Abstract:

目的检测microRNA-21(miR-21)与microRNA-205(miR-205)在初、复发膀胱尿路上皮癌中的表达情况,探讨microRNAs(miRNAs)在膀胱尿路上皮癌中的表达意义及是否与肌层浸润有关。方法采用基于2-△△CT的实时定量PCR(Real-timePCR)方法检测40例初、复发癌组织miR-21及miR-205的表达情况。结果与初发癌相比,复发癌miR-21表达上调(P<0.05),miR-205表达下调(P<0.05);与非肌层浸润性癌相比,肌层浸润性癌miR-21表达上调(P<0.05),miR-205表达下调(P<0.05);肌层浸润性癌miR-21与miR-205表达量的比值5倍于其在非肌层浸润性癌中表达量的比值。结论miR-21高表达、miR-205低表达可能参与膀胱尿路上皮癌复发并与肌层浸润有关。
