1超声和微泡造影剂介导细胞基因转染的实验研究显示文摘目的 探讨低频超声对细胞基因转染的作用。方法 超声治疗仪频率1MHz,脉冲重复频率100Hz,占空系数20%。质粒DNA为含编码绿荧光蛋白的pEGFP。应用荧光显微镜和流式细胞仪评价细胞基因转染率,台盼蓝染色计算细胞成活率。选用C2C12、3T3-MDEI和CHO3种细胞系为研究对象,加入DNA后辐照不同声强、时间或加入超声造影剂,观察各条件下的细胞基因转染率和成活率。结果 ①超声介导的基因转染与声强和辐射时间有关,最佳剂量为1w/cm^2 20s;②同样超声剂量,较高的声强较早达到最大基因转染率;③较低剂量时,微泡造影剂可使超声介导的基因转染提高2~3倍并可显著提高最高基因转染率。结论 低频超声可介导细胞基因转染,基因转染率不但与超声辐射剂量有关,而且同样剂量时,高声强较早达到最大基因转染率,最佳剂量是1w/cm^2 20s。同时,微泡造影剂可提高超声介导基因转染的最高转染率。陈云超 张青萍 LIANG Hai-dong 朱蔚 张超 Martin JK Blomley LU Qi-long 2006中华超声影像学杂志2006,15,11:22
2共聚物在超声介导基因转染中的新功能显示文摘目的探讨超声和共聚物在促进基因转染中是否有协同作用.方法应用3种水溶性不同的共聚物F127,L61和P85.超声参数设定为1 MHz,1~3 W/cm2,脉冲作功周期为20%.选用C2C12,3T3-MDEI,和CHO 3种细胞系为研究对象.质粒DNA为可产生绿色荧光蛋白的GFP.应用荧光显微镜和流式细胞仪(FACS)评价转染率,台盼蓝染色评价细胞的成活率.每一实验结果至少重复3次以上.结果与以前的研究结果相同,超声可介导基因转染,但随着超声能量的增加,细胞的破坏也增加;单独应用3种共聚物未观察到基因转染.但当与超声同时应用,在较低浓度时共聚物可使超声介导的基因转染率提高2~4倍.结论在较低浓度时,共聚物可显著提高超声介导的基因转染作用.陈云超 张青萍 LIANG Hai-Dong David O.
