1、摘要目的探讨脂质体法转染Raf激酶抑制蛋白(RKIP)基因对宫颈癌细胞的影响。方法运用脂质体法将含有人RKIP基因的反义质粒asRKIP及空白质粒pcDNA3.1(一)分别转染宫颈癌Caski细胞,采用G418筛选出稳定转染的宫颈癌细胞(转染细胞及对照细胞组),空白质粒转染后Caski细胞即为空白对照细胞命名为Caski一(一),asRKIP转染后Caski细胞分为平行的两组分别命名为Caski-asRKIP#1细胞和Caski—asRKIP#2细胞;采用四甲基偶氮唑蓝(MTT)法、软琼脂集落形成实验和Transwell小室实
2、验检测RKIP表达下调对宫颈癌细胞的影响。结果成功建立了RKIP表达下调的Caski宫颈癌细胞系;Caski-asRKIP#1和Caski—asRKIP#2细胞的增殖速度比Caski一(一)细胞和Caski细胞快(t=5.32、4.98、6.43、5.34,P0.05);体外非依赖性生长:Caski-asRKIP#1细胞(239±9.3个)和Caski—asRKIP#2细胞(228±8.9个)与Caski-(一)细胞(73
