摘要 目的:探讨pSilencer1.0-U6-siRNA-STAT3重组质粒抑制人卵巢癌SKOV3细胞裸鼠皮下移植瘤生长及诱导肿瘤细胞凋亡的作用。方法:应用人卵巢癌细胞株SKOV3对15只裸鼠构建卵巢癌移植瘤模型,随机分为生理盐水对照组、空质粒对照组、重组质粒组。联合电转染技术向裸鼠移植瘤内注射重组质粒,每隔5天重复注射1次,每4天测量各组裸鼠皮下移植瘤体积。采用TUNEL法检测肿瘤组织细胞的凋亡情况。结果:重组质粒瘤内注射对卵巢癌移植瘤生长有明显的抑制作用,与两个对照组比较重组质粒组裸鼠移植瘤生长速度明显减慢(P<0.01)。TUNEL染色显示重组质粒组癌组织有大量细胞凋亡。结论:pSilencer1.0-U6-siRNA-STAT3重组质粒能有效诱导人卵巢癌裸鼠皮下移植瘤组织中细胞凋亡,抑制肿瘤生长。
