Rap2a对肺癌细胞侵袭能力的影响及其机制DOI: 10.3971/j.issn.1000-8578.2016.08.004 Keywords: A Meta-analysis,Effect of Ectopic Expression of Transmembrane Adaptor PAG1 on Motility of Cutaneous Squamous Cell Carcinoma A431 Cells in vitro,Immune Killing Effect of Silencing TIPE2 Expression on T Lymphocytes Against Lung Adenocarcinoma Cells LA795,NSCLC的疫苗治疗研究进展,Effects on Cell Proliferation, Invasion and Migration of Esophageal Adenocarcinoma by Inhibition of Notch and PI3K /Akt Pathway,Experiment of Different Administration Sequences of Apatinib and Paclitaxel on Lung Cancer Abstract: 摘要 目的 检测小G蛋白家族成员Rap2a对人肺癌细胞迁移侵袭的影响及机制探讨。方法 构建pcDNA3.1-Rap2a质粒,转染入A549和H1299细胞,运用划痕和Transwell小室实验观察Rap2a对肺癌细胞侵袭能力的影响。CCK-8和流式细胞术检测Rap2a对细胞增殖和凋亡的影响,Western blot检测Bcl-2、Bax、ERK和Akt等的蛋白表达水平。结果 与空质粒组相比,转染Rap2a质粒的肺癌细胞侵袭能力明显增加,但细胞的增殖和凋亡能力无明显变化, Bcl-2和Bax的蛋白水平也无明显变化。Western blot结果显示,Rap2a过表达后p-Akt473的表达水平增加。结论 人Rap2a促进肺癌细胞的迁移侵袭可能与Rap2a影响Akt磷酸化水平有关
