摘要 目的:通过构建miR-214的真核表达载体,研究其对人肺癌A549细胞增殖和侵袭能力的影响。方法:以A549细胞基因组DNA为模板,扩增得到miR-214前体序列,插入表达载体pcDNA3.1(+)克隆获得pcDNA3.1(+)-miR-214。将真核表达载体pcDNA3.1(+)-miR-214转染到A549细胞中,并采用实时荧光定量PCR(real-time PCR)对其表达情况进行验证。采用MTT和transwell小室等方法分别检测转染重组质粒pcDNA3.1(+)-miR-214对A549细胞增殖能力和侵袭能力的影响。结果:成功构建了miR-214稳定过表达的真核表达载体pcDNA3.1(+)-miR-214;real-time PCR检测结果表明,转染pcDNA3.1(+)-miR-214后A549细胞中miR-214过表达(P<0.05)。miR-214过表达后A549细胞的增殖和侵袭能力均明显降低。结论:miR-214在A549细胞中过表达能够抑制细胞的增殖和侵袭能力,为进一步深入研究miR-214在肿瘤中的作用机制提供了实验依据。
