摘要: 目的 本研究旨在探讨survivin 与bcl-2 基因反义寡脱氧核苷酸联合对人乳腺癌裸鼠皮下移植瘤的治疗作用。方法 在BALB/c 裸鼠上建立MCF-7乳腺癌细胞株模型, 然后随机分成阴性对照组和5个实验组[ 分别为脂质体survivin 正义脱氧寡核苷酸(SODN)组、脂质体bcl-2 SODN 组、脂质体survivin 反义寡脱氧核苷酸(ASODN)组、脂质体bcl-2 ASODN组、联合反义给药组] 。检测裸鼠体重及肿瘤体积变化, 计算抑瘤率及肿瘤缩小率。结果 给药后, 联合反义给药组的肿瘤体积抑瘤率为78.4%, 肿瘤重量抑瘤率为75.3%, 肿瘤缩小率为41.6%。在给药后,各组裸鼠体重变化无明显统计学差异(P>0.05)。结论 survivin 与bcl-2 基因反义寡核酸联合在体内能明显抑制肿瘤生长。

Abstract: AIM: To investigate the effects of surviving and bcl-2 combined with ASODN on the treatment of breast cancer xenograft in nude mice.METHODS: The model of xenografts derived from MCF-7 breast cancer cell was established in BALB/c nude mice , then they were randomly divided into a negative control grouPand 5 experimental groups [intraperitoneal injection of liposomesurvivin-SODN , liposome-bcl-2-SODN , liposome-survivin-ASODN , liposome-bcl-2-ASODN , combined ASODN].The tumor growth inhibitory rate and the tumor volume decreased rate were calculated.RESULTS: Survivin and bcl-2 combined with ASODN exhibited potent tumor growth inhibition.The tumor volume inhibitory rate was 78.4%;the tumor weight inhibitory rate was 75.3%;the tumor volume decreased rate was 41.6%for combined grouPpost-experiment of the 6 groups , and there was no significant difference on nude mice weight post-experiment.CONCLUSION: Survivin and bcl-2 combined with ASODN showed potent tumor growth inhibition in vivo.
