摘要

目的:观察以脂质体为载体介导血管内皮生长因子（Vascular endothelial growth factor

VEGF）反义寡核苷酸（Antisense oligonucleotides

ASODN）转染对裸鼠膀胱癌移植瘤的抑制作用。方法:建立人膀胱癌裸鼠皮下移植瘤模型

以脂质体为载体介导VEGFASODN进行转染。观察裸鼠移植瘤生长情况

免疫组化SP法测Ki67、CD34、VEGF的表达

计算微血管密度、细胞增殖指数

TUNEL法测细胞凋亡指数。结果:反义组与正义组的抑瘤率分别为71.08%和7.19%

反义组VEGF的表达、微血管密度、细胞增殖和凋亡指数与正义组及对照组相比均有明显差异

正义组与对照组之间各检测指标差异无显著性。结论:VEGF反义寡核苷酸能够抑制人膀胱癌裸鼠皮下移植瘤的生长和微血管的生成

可能成为日后膀胱癌基因治疗的重要方向。

Abstract

Objective:To study the inhibiting effect of VEGF antisense oligonucleotides carried by liposome on the growth of human bladder carcinoma in nude mice. Methods:The nude mice model of human bladder carcinoma was established and VEGF antisense oligonucleotides were carried by liposome to be transfected.The cell proliferation index

microvessel density (MVD) and the expression of VEGF were detected with immunohistochmistry streptavidin-biotin peroxidase(SP) method and the cell apoptosis index was determined with Tunnel technology. Results:The growth inhibitory rate in antisense experimental group and sense experimental group were 71.08% and 7.19% respectively. The differences in the cell proliferation index

apoptosis index

microvessel density(MVD) and the expression of VEGF between the antisense experimental group and the sense experimental group or the control group had significances. There was no statistical significance in the detection indexes between the sense experimental group and the control group. Conclusions:The VEGF antisense oligonucleotides can inhibit the neovascularization and the growth of bladder carcinoma in nude mice

which might be an important gene therapeutic strategy for the bladder carcinoma in future.
