目的:探讨蛋白转导域(protein transduction domain,PTD)-染色质修饰蛋白1A(chromatin modifying protein 1A,CHMP1A)融合蛋白对肾细胞癌(renal cell carcenoma,RCC)细胞增殖、迁移、侵袭及体内移植瘤生长的影响。方法:分别用1、5、20μg/ml的PTD-CHMP1A(PTD-CHMP1A组)、5μg/ml的野生型CHMP1A(CHMP1A组)和PBS(PBS组)处理RCC细胞株A498和786-0。用MTT法检测PTD-CHMP1A对A498细胞增殖能力的影响,划痕愈合实验检测PTD-CHMP1A对A498细胞迁移能力的影响,用Transwell侵袭实验检测PTD-CHMP1A对A498和786-0细胞的侵袭能力的影响。将5×105个/ml的A498细胞注射于裸鼠体内,构建RCC移植瘤模型,观察20μg的PTD-CHMP1A对移植瘤生长的影响。结果:与CHMP1A和PBS组比较,1、5和20μg/ml的PTD-CHMP1A对A498细胞的增殖均出现不同程度的抑制作用,且呈明显的剂量和时间相关性;5μg/ml的PTDCHMP...
