The expression of microRNA-215 (miR-215) in non-small cell lung cancer (NSCLC) tissues and the effects of miR-215 on the proliferation and migration of NSCLC cells were investigated. qRT-PCR was used to detect the expression of miR-215 in NSCLC tissues and paired normal tumor-adjacent lung tissues; MTT assay, transwell assay and soft-agar assay were used to evaluate the role of miR-215 on proliferation, migration and cell clonality on NSCLC cells, after transfecting miR-215 mimics to NSCLC cell line A549 or miR-215 to H1299. miR-215 was significantly decreased in NSCLC tissues compared to the paired normal tissues; Overexpression of miR-215 in A549 cells resulted in reduction of the cell proliferation, migration and cell clonality, while downregulation of miR-215 in H1299 cells could promote cell proliferation, migration and clonality. In conclusion, miR-215 was downregulated in NSCLC tissues and may play a key role in the development of NSCLC.
研究了非小细胞肺癌（NSCLC）组织中微小RNA-215（miR-215）的表达以及miR-215对NSCLC细胞增殖和迁移的影响。采用qRT-PCR检测NSCLC组织及配对的肿瘤旁正常肺组织中miR-215的表达；在将miR-215模拟物转染至NSCLC细胞系A549或miR-215转染至H1299后，采用MTT法、Transwell法和软琼脂法评估miR-215对NSCLC细胞增殖、迁移和细胞克隆性的作用。与配对的正常组织相比，NSCLC组织中miR-215显著降低；A549细胞中miR-215的过表达导致细胞增殖、迁移和细胞克隆性降低，而H1299细胞中miR-215的下调可促进细胞增殖、迁移和克隆性。总之，miR-215在NSCLC组织中表达下调，可能在NSCLC的发生发展中起关键作用。
