目的 分析研究miR-125a-5p在不同分化程度结直肠癌(CRC)中的表达水平,探讨其对不同分化CRC的诊断意义.方法 采用实时荧光定量PCR分析miR-125a-5p在26例不同分化程度CRC患者肿瘤和瘤旁组织中的表达水平,比较miR-125a-5p在肿瘤和瘤旁组织中表达水平的差异.通过受试者特征曲线(ROC)分析miR-125a-5p作为诊断标志筛查CRC患者的特异性和敏感性.结果 相对瘤旁正常组织,miR-125a-5p在高、中分化CRC组织中的表达水平均明显下降,其中在高分化肿瘤样本中的表达水平下降了近300%(P=0.047),在中分化CRC中下降超过500%(P=0.000).miR-125a-5p对筛查中分化CRC具有较高的敏感度和特异度,分别达到80.00%、90.00%.结论 不同分化程度CRC中miR-125a-5p表达水平均明显下降,提示miR-125a-5p在CRC的分化发展中具有重要作用.miR-125a-5p具有作为CRC临床筛查指标的潜能.

Objective To identify the expression level of miR-125a-5p in colorectal cancer (CRC) with various differentiation,and to investigate its diagnostic significance.Methods Real-time polymerase chain reaction was used to analyze the expression level of miR-125a-5p in tumors and paired normal tissues of different differentiated CRC.Receiver-operating-characteristic (ROC) curve was performed to evaluate the specificity and sensitivity of using miR-125a-5p as biomarkers to discriminate CRC patients from normal persons.Results Compared with normal tissues,miR-125a-5p was down-regulated in both high and moderate differentiation,miR-125a-5p could distinguish CRC from normal persons with high sensitivity and specificity,which were 80.00 % and 90.00 %,respectively.Conclusions miR-125a-5p down-regulated in CRC indicates that miR-125a-5p contributes to tumorigenesis,and may be a potential biomarker for CRC.
