摘要:

目的  检测microRNA-150 (miR-150) 在结肠癌细胞株、结直肠癌(CRC)组织中的表达,分析其与临床特征间的关系。方法  采用实时荧光定量逆转录聚合酶链反应(qRT-PCR)检测8种结肠癌细胞株及45例CRC患者癌组织及对应正常组织中miR-150的表达情况,分析其表达与CRC临床病理资料之间的关系。结果  miR-150在8种结肠癌细胞株中表达明显降低,CRC组织中miR-150的表达较同一患者正常黏膜组织中的miR-150表达明显下调(P<0.05);miR-150在CRC组织中的表达与肿瘤的分化程度(P<0.05)及病理类型(P<0.01)密切相关。结论  miR-150在CRC中表达下调,其低表达与CRC的分化及病理类型相关,可作为结直肠癌诊断及治疗的指标之一。

Abstract:

Objective  To study the expression of microRNA-150(miR-150) in colon cancer cell lines and colorectal cancer (CRC) tissues, and evaluate its clinicopathological significance. Methods  miR-150 was examined in eight colon cancer cell lines, 45 CRC tissues and their matched normal tissues by real-time quantitative reverse transcription PCR (qRT-PCR). The relationships between miR-150 and clinicopathological information were analyzed. Results  Expression of miR-150 in eight colon cancer cell lines was lower than normal tissues. Moreover, miR-150 expression in tumor tissues was much lower than their matched normal tissues (P<0.05). Low miR-150 level was strongly associated with the differentiated degree (P<0.05) and pathological type (P<0.01). Conclusion  miR-150 is down-regulated not only in colon cancer cell lines but in tumor tissues, and its low expression is associated with the differentiation and pathological type. miR-150 might play a role in the course of CRC diagnosis and treatment.
