文摘目的探讨肾母细胞瘤基因1(WT1)对鼻咽癌细胞(CNE)-2表皮生长因子受体(EGFR)的靶向作用,证实WT1对CNE-2免疫活性的影响。方法采用WT1对CNE-2进行处理,借助蛋白质免疫印迹法(Western blot)对EGFR的蛋白表达情况进行检测,借助CKK-8观察CNE-2增殖能力情况,借助流式细胞术观察CNE-2凋亡情况,借助基质胶侵袭试验(Transwell)测定CNE-2侵袭情况。结果 Western blot测定结果显示,采用WT1组信号强度明显低于二甲亚砜(DMSO)组和空白组,差异均有统计学意义(P<0.05);WT1组检测灰度值为0.358±0.148,DMSO组为1.370±0.068,空白组为1.390±0.077,WT1组检测灰度值明显低于DMSO组和空白组,差异均有统计学意义(P<0.05)。CKK-8检测结果显示,采用WT1进行处理后3、6、9、12h,抑制值表现为逐渐增大,差异有统计学意义(P<0.05)。流式细胞术检测结果显示,空白组细胞凋亡率为(0.832±0.207)%,DMSO组为(2.081±1.221)%,WT1组为(20.731±1.104)%,WT1组细胞凋亡率高于空白组和DMSO组,差异均有统计学意义(P<0.05)。Transwell测定结果显示,DMSO组穿透细胞数量为67.21±2.17,WT1组为20.13±2.25,WT1组穿透细胞数量低于DMSO组,差异有统计学意义(P<0.05)。结论 WT1抗原能够作为CNE-2EGFR的靶向基因,可较好地实现对CNE-2EGFR免疫活性的抑制。
