%X 目的 研究Yes相关蛋白1（YAP1）在非小细胞肺癌细胞增殖、细胞周期、迁移、侵袭中的作用。方法 通过慢病毒介导的小干扰RNA靶向抑制人非小细胞肺癌细胞株A549中YAP1基因的表达，采用CCK-8法、流式细胞术分别检测沉默YAP1对A549细胞增殖及凋亡周期的影响，Transwell实验观察沉默YAP1对A549细胞迁移、侵袭能力的影响。结果 沉默YAP1后，A549细胞YAP1 mRNA和蛋白表达均下调（P<0.01），CCK-8实验结果显示沉默YAP1抑制A549的增殖、增加G0/G1期的细胞比例（P<0.01），Transwell实验结果示沉默YAP1抑制A549细胞的迁移、侵袭（P<0.01）。结论 沉默YAP1基因对非小细胞肺癌细胞的恶性生物学特征具有抑制作用，YAP1可能成为肺癌治疗的潜在靶标。</br>Objective To explore the role of Yes-associated protein 1 (YAP1) in the proliferation, cell cycle, migration and invasion of human non-small cell lung cancer (NSCLC) cells. Methods A lenti-siRNA targeting YAP1 (si-YAP1) was used to inhibit the expression of YAP1 gene of human NSCLC cell line A549 cells. CCK-8 assay and flow cytometry were used to determine the effects of silencing of YAP1 expression on A549 cells proliferation and cell cycle, respectively; Transwell assay was used to observe the effect of silencing of YAP1 expression on A549 cell migration and invasion. Results After infection with si-YAP1, the expressions of YAP1 mRNA and protein in A549 cells were significantly down-regulated (P<0.01). YAP1 silencing significantly inhibited A549 cell proliferation, increased the percentage of cells in G0/G1 phase (P<0.01), and significantly decreased the migration and invasion of A549 cells (P<0.01). Conclusion YAP1 silencing can inhibit malignant biological characteristics of NSCLC, which suggests that YAP1 gene may serve as an important target in the gene therapy of lung cancer
