摘要(Abstract):

目的:用聚丙烯酸甲酯/离子霉素(PMA/IONO)和MALT1抑制剂Z-VRPR-FMK刺激Burkitt淋巴瘤细胞,检测细胞内MALT1和A20蛋白的表达。方法:采用200μg/L+1μmol/L的PMA/IONO和不同浓度(25、50和75μmol/L)的Z-VRPR-FMK、在不同的作用时间(0.25、0.5和2 h)下刺激培养的Burkitt淋巴瘤细胞Raji,根据各组细胞中A20蛋白的表达情况确定抑制剂Z-VRPR-FMK的最佳作用浓度及时间;将培养的Raji细胞分为设对照组、激动剂PMA/IONO处理组和抑制剂Z-VRPR-FMK处理组;对照组不加入Z-VRPR-FMK和PMA/IONO处理,抑制剂Z-VRPR-FMK处理组和激动剂PMA/IONO处理组分别根据筛选的Z-VRPR-FMK最佳作用浓度和时间进行刺激培养,采用Western bloting法各组检测各组细胞中MALT1和A20蛋白的表达。结果:最适的ZVRPR-FMK作用浓度为75μmol/L、作用时间为0.5 h;与对照组相比,激动剂PMA/IONO处理组与抑制剂Z-VRPR-FMK处理组MALT1蛋白表达差异无统计学意义(P>0.05),但两组的A20蛋白表达均明显升高(P<0.01)。结论:抑制剂Z-VRPR-FMK能促进培养的Raji细胞内A20蛋白表达上调。
Objective: To stimulate cultured Burkitt lymphoma cell with PMA/IONO and Z-VRPRFMK separately,and detect the expression of MALT1 and A20 protein. Methods: Raji cells were cultured. According to A20 protein expression condition,the best concentration and time of Z-VRPRFMK was screened by using different concentration( 25 μmol/L,50 μmol/L,75 μmol/L) and time( 0. 25 h,0. 5 h,2 h) of Z-VRPR-FMK as well as 200 mg/L and 1 μmol/L PMA/IONO. Cultured Raji cells were divided into control group and PMA/IONO agonist treatment group and inhibitor Z-VRPR-FMK treatment group,control group didn't treat with Z-VRPR-FMK or PMA/IONO,PMA/IONO agonist treatment group and inhibitor Z-VRPR-FMK treatment group were given Z-VRPR-FMK at screened optimum concentration and time. MALT1 and A20 protein was detected by western blotting.Results: The best concentration and time of Z-VRPR-FMK were 75 μmol/L and 0. 5 h separately.Compared with control,there was no change of MALT1 expression in two experimental groups,but A20 expression was significantly increased in the two groups( P < 0. 01). Conclusion: The inhibitor Z-VRPR-FMK can promote the expression of A20 protein in cultured Raji cells.
