WT1反义核酸诱导卵巢癌细胞凋亡的实验研究

[目的]研究WT1反义寡核苷酸转染对卵巢癌SKOV3细胞增殖和凋亡的影响。[方法]实验分4组:正常对照组(加入转染液)、反义组(脂质体+反义寡合苷酸转染)、正义组(脂质体+正义寡合苷酸转染)和脂质体组(只加入脂质体)。分组转染卵巢癌SKOV3细胞株后,流式细胞仪检测细胞凋亡和细胞周期,MTT法检测细胞的增殖活性,RT-PCR检测WT1 mRNA表达水平,Western blot检测其蛋白表达水平。[结果]脂质体介导的WT1反义寡核苷酸转染明显抑制卵巢癌SKOV3细胞增殖,抑制率为49.48%,G0-G1期细胞分布率增加达(79.10±2.79)%,凋亡细胞群明显增多,凋亡率为(13.18±2.00)%,同时转染后细胞WT1 mRNA及蛋白表达水平下降,与对照组及其他各组相比较差异均有显著性意义(P<0.05)。[结论]WT1反义核酸能抑制卵巢癌细胞增殖,诱导细胞凋亡。WT1反义核酸用于卵巢癌的基因治疗具有一定的潜在意义。

Effect of WT1 antisense mRNA on the induction of apoptosis in ovarian carcinoma SKOV3 cells

[Objective] To study the effect of WT1 antisense oligodeoxynucleotides(ASODN) transfection on the cell proliferation and apoptosis of SKOV3 cells.[Methods] There were 4 groups in our study: normal control group,WT1 ASODN group,WT1 SODN group and Lipofectamine group.The cell apoptosis was observed by flow cytometry.The effect of WT1 ASODN on cell proliferation was assayed by MTT method.The expression level of WT1 mRNA and protein were detected by RT-PCR and Western blot.[Results] The growth of the ovarian ca...
