摘要 目的观察非小细胞肺癌(NSCLC)组织中miR-34a的表达情况及其对NSCLC细胞系H1299增殖的影响。方法 RT-PCR方法检测miR-34a在NSCLC组织和NSCLC细胞系H1299中的表达情况。克隆形成实验及MTT增殖实验检测miR-34a对NSCLC细胞系H1299增殖能力的影响;生物信息学方法预测miR-34a可能的功能性靶基因,并采用荧光素酶报告基因实验验证预测的功能性靶基因。Western印迹检测miR-34a对预测靶基因表达的影响。结果相比正常组织而言,NSCLC组织和细胞系H1299中miR-34a表达均显著下降(P<0.05);转染miR-34a可显著抑制NSCLC细胞系H1299的增殖能力(P<0.05),而转染miR-34a抑制剂可增加NSCLC细胞系H1299的增殖能力(P<0.05)。生物信息学预测显示Notch1是miR-34a可能的功能性靶基因,且得到荧光素报告实验结果证实。Western印迹结果显示转染miR-34a可显著抑制NSCLC细胞系H1299中Notch1的表达。结论 miR-34a可通过调节Notch1的表达,进而抑制NSCLC细胞的增殖。
