摘要 目的探讨抑制乳腺癌抗雌激素药物耐药蛋白(BCAR1)表达对肺癌细胞系A549 P38和p-P38表达的影响。方法培养正常A549细胞(对照组)、慢病毒BCAR1基因干扰A549细胞(干扰组)和慢病毒阴性对照A549细胞(阴性对照组),用Western blot检测细胞P38和p-P38表达水平,用克隆形成实验、流式细胞计量术、Transwell实验和划痕实验检测细胞的细胞克隆、细胞周期、细胞侵袭和迁移能力。结果干扰组p-P38表达显著低于其他两组(P〈0.05);干扰组细胞G1期比例显著高于其他两组(P〈0.05);干扰组细胞增殖、侵袭和迁移能力低于其他两组(P〈0.05)。结论抑制BCAR1表达可下调p-P38表达,减弱肺癌A549细胞增殖、迁移和侵袭能力。 Objective To discuss the effect of breast cancer anti-estrogen resistance 1( BCAR1) knockdown on the expression of P38 and p-P38 in lung cancer cell line A549. Methods A549 cells( control group),A549 cells with RNAi letiviral vector of BCAR1( interference group) and A549 cells with negative control letiviral vector( negative group) were cultured. Western blot was used to detect the expression of P38 and p-P38. The proliferation,cell cycle,migration and invasion were measured by colony formation assay,flow cytometer,transwell experiment and scratch adhesion test,respectively. Results p-P38 expression in interference group cells was significantly lower than that in other two group cells( P〈0. 05).G1 phase of interference group cells was significantly increasing than that in other two group cells( P〈0. 05).The proliferation,migration and invasion of interference group cells were all significantly suppressed as compared with that of other two group cells( P 0. 05). Conclusions BCAR1 knockdown decreases p-P38 expression and inhibits proliferation,migration and invasion of A549 cells.
