摘要 目的探讨真核始动因子4E(eIF4E)反义寡核苷酸(ASODN)对人膀胱癌BIU.87细胞株中elF4E及肝素酶(HPA)蛋白、mRNA表达的影响。方法采用脂质体介导方法分别将2.5、5.0及7.5μg/mleIF4EASODN转染膀胱癌BIU-87细胞,并设立细胞对照组(不转染)、空白对照组(转染空脂质体)及无关对照组(转染无关对照ASODN),分别转染24、48及72h,采用原位杂交、免疫细胞化学方法分别检测各组BIU-87细胞中eIF4E及HPA蛋白、mRNA表达。结果elF4EASODN各转染组细胞中eIF4E蛋白及mRNA表达量均较对照组降低(蛋白:2.5μg/ml组分别为3.55±0.52、3.52±0.51、3.22±0.44;5.0μg/ml组分别为3.43±0.47、3.41±0.46、3.19±0.41;7.5μg/ml组分别为2.36±0.39、2.33±0.37、2.05±0.30。mRNA:2.5μg/ml组分别为3.19±0.41、3.13±0.39、2.90±0.38;5.0μg/ml组分别为3.07±0.39、2.94±0.38、2.27±0.37;7.5μg/ml组分别为2.22±0.37、2.06±0.30、1.95±0.29),与细胞对照组、空白对照组和无关对照组相应时间段、相应浓度组两两比较差异均有统计学意义(P〈0.05),且具有时间和浓度依赖性。elF4EASODN各转染组细胞中HPA蛋白及mRNA表达量均较对照组降低(蛋白:2.5μg/ml组分别为4.44±0.55、4.40±0.54、3.99±0.52;5.0μg/ml组分别为4.41±0.55、4.21±0.53、3.77±0.50;7.5μg/ml组分别为4.02±0.52、3.98±0.52、2.32±0.37。mRNA:2.5μg/ml组分另0为4.12±0.51、3.75±0.50、3.63±0.45;5.0μg/ml组分别为4.00±0.51、3.71±0.50、3.5±0.44;7.5μg/ml组分别为3.87±0.52、3.61±0.49、2.08±0.30),与细胞对照组、空白对照组和无关对照组两两比较差异均有统计学意义(P〈0.05),且具有时间和浓度依赖性。eIF4EASODN对HPA蛋白、mRNA表达的抑制效应和对 Objective To explore the influence on the expression of elF4E and heparanase by antisense oligodeoxyribonueleotides (ASODN) transfection in human bladder carcinoma BIU-87 cells. Methods After transfeeting the 2.5, 5.0, 7.5 μg/ml eIF4E ASODN into BIU-87 cells, at 24 h, 48 h and 72 h, a cell control group (no transfeetion) , a blank control group (empty liposomes) and a non-sense control group (transfected with non-sense ASODN) were established. The expression of eIF4E, HPA and mRNA were detected by in situ hybridration. The expression of elF4 and HPA protein were detected by immunocytochemistry. SPSS 13.0 statistical software was used for statistical analysis. Results The expression quantity of elF4E protein and mRNA were lower in the experimental groups ( protein: 2.5 μg/ml ASODN treated 24 h, 48 h, 72 h were: 3.55 ±0.52, 3.52 ±0.51, 3.22. ±0.44 respectively; 5.0 μg/ml group: 3.43 ± 0.47, 3.41 ±0.46, 3.19 ±0.41 respectively; 7.5 μg/ml group: 2.36±039, 2.33 ±0.37, 2.05 ±0.30 respectively, mRNA : 2.5 μg/ml treated 24 h, 48 h, 72 h were : 3.19 ± 0. 41, 3.13 ± 0.39, 2.90 ± 0.38 respectively ; 5.0 tzg/ml group : 3.07 ± 0.39,2.94 ± 038,2.27 ± 0.37 respectively ; 7.5 μg/ml group : 2.22 ± 037, 2.06 ± 0. 30, 1.95 ± 0.29 respectively. All data were less than those in the control groups (P 〈 0. 05). The expression quantity of HPA protein and mRNA were lower in experimental groups ( protein: 2.5 μg/ml ASODN treated 24 h, 48 h, 72 h were: 4.44 ±0.55, 4.40 ±0.54, 3.99 ±0.52 respectively; 5.0 μg/ml group: 4.41 ±0.55, 4.21 ±0.53, 3.77 ±0.50 respectively; 7.5 bμg/ml group: 4.02 ± 0.52, 3.98±0.52, 2.32±0.37 respectively, mRNA: 2.5 μg/l treated 24 h, 48 h, 72 hwere: 4.12± 0.51, 3.75 ±0.50, 3.63 ±0.45 respectively; 5.0 μg/l group: 4.00 ±0.51, 3.71 ±0.50, 3.54 ±0.44 respectively; 7.5 μg/ml group: 3.87 ± 0.52, 3.61 ± 0.49, 2.08 ± 0.30 respectively).
