摘要 目的:探讨瘤内注射vivo-jetPEITM/pEGFP Mfn2复合物对裸鼠移植瘤增殖的影响。方法:质粒pEGFPMfn2的构建及检测,将MCF-7细胞异种移植到裸鼠体内,建立人乳腺癌移植瘤模型,用vivo-jetPEITM试剂制备vivo-jetPEITM/DNA复合物,实验共分为实验组、空载体对照组和空白对照组。瘤内多点注射,RT-PCR检测肿瘤组织线粒体融合素-2(Mfn2)的表达,免疫组化检测Ki-67、血管内皮生长因子(VEGF)的表达情况。结果:pEGFPMfn2构建成功并测序证实,实验组的相对平均吸光度值为(1.12±0.05)高于空载体对照组的(0.16±0.05)和空白对照组(0.17±0.07)(P<0.05),Ki-67在实验组的相对平均吸光度为(0.25±0.06)高于空载体对照组的(0.11±0.02)和空白对照组(0.12±0.03)(P<0.05),而VEGF在实验组的相对平均吸光度为(0.09±0.01)低于空载体对照组的(0.14±0.08)和空白对照组的(0.13±0.03)(P<0.05)。结论:vivo-jetPEITM试剂能成功将Mfn2基因转染进瘤体细胞,Mfn2基因对人乳腺癌裸鼠移植成瘤后的Ki-67和VEGF有影响。
