摘要(Abstract):
目的:探讨转染Smac基因对卵巢癌SKOV3/DDP裸鼠移植瘤顺铂敏感性及微血管生成的影响。方法:建立卵巢癌SKOV3/DDP裸鼠移植瘤模型,随机分为5组,分别给予不同药物干预:(1)对照组:移植瘤内注射生理盐水;(2)DDP组:腹腔内注射顺铂;(3)空质粒+DDP组:移植瘤内注射空质粒,24h后腹腔内注射顺铂;(4)Smac组:移植瘤内注射Smac重组质粒;(5)Smac+DDP组:移植瘤内注射Smac重组质粒,24h后腹腔内注射顺铂。顺铂浓度为0.5mg/m1,给药剂量按3mg/kg计算。观察各组裸鼠移植瘤体积变化,计算抑瘤率。TUNEL法检测移植瘤组织标本的凋亡指数,免疫组化法检测CD34并计算微血管密度(MVD)。结果:Smac+DDP组的移植瘤体积最小,平均抑瘤率72.94%,与其他组比较差异有统计学意义(P<0.05)。对照组、DDP组、空质粒+DDP组、Smac组、Smac+DDP组的凋亡指数分别为(19.90±3.18)%,(21.82±4.40)%,(22.64±3.81)%,(30.23±4.06)%,(48.59±4.47)%,MVD计数分别为(24.8±5.36),(21.2±3.11),(19.8±3.70),(14.4±3.85),(11.6±2.70)。其中,Smac+DDP组的凋亡指数最高,MVD最低,与其他组比较差异有统计学意义(P<0.05)。结论:Smac基因转染可增强卵巢癌耐药移植瘤对顺铂的敏感性,同时减少微血管生成。
