Cell proliferation and viability were assayed 48h after transfection, and MDA-7 demonstrated selective inhibition of tumor cell growth, inhibitory rates of A549, Hela and HepG2 cell lines were 25%, 20% and 19%, respectively, but had no significant effect on human fetal kidney derived 293 cell line. Hela cell was screened by G418 for 2 weeks after pcDNA3-MDA-7 and monolayer colony was counted, its monolayer colony formation was 30% of cells transfected with pcDNA3. 0 vector. CMV-driven MDA-7 adenovirus vector was constructed. 293 showed no significant apoptosis during adenovirus packaging and the unpurified adenovirus titer was about 1×10〓pfu/ml. Cos 7, A549, Hela, HepG2 and Hep3B cell was infected with Ad-GFP at different MOI.

二。黑色素细胞分化相关蛋白-7（MDA-7）的克隆及功能研究：利用RT-PCR方法从5月龄人胚胎脾细胞扩增MDA-7的编码序列，经测序鉴定序列与文献报道一致后，与真核表达载体pcDNA3.0连接，构建pcDNA3-MDA-7表达载体，瞬时转染293、A549、Hela和HepG2细胞后抽提细胞总RNA，RT-PCR结果显示表达载体可介导MDA-7在不同细胞系中有效表达；转染48h后测定细胞增殖和活力，MDA-7可选择性抑制肿瘤细胞的增殖，对A549、Hela和HepG2细胞的抑制率分别为25％、20％和19％，但是对人胚肾来源的293细胞生长无明显影响。pcDNA3-MDA-7载体转染Hela细胞后，以G418筛选2周后计数单层细胞集落形成数，计数仅为转染pcDNA3.0空载体的细胞的30％左右。
