摘 要:目的探讨基质金属蛋白酶抑制剂MMI-166对人胰腺癌SW1990细胞增殖和凋亡的影响。方法应用不同浓度(25、50、100μg/m1)的MMI-166处理人胰腺癌SW1990细胞24、48h。用四甲基偶氮唑蓝(MTT)法检测细胞增殖抑制率;采用AnnexinV—PI法检测细胞凋亡,流式细胞术检测细胞凋亡率。结果25、50、100μg/mlMMI-166处理细胞24h后,细胞生长抑制率分别为(34.23.4-3.87)%、(44.81±2.01)%、(53.91±1.74)%;48h的抑制率为(39.95±1.83)%、(52.26±3.46)%、(63.20±2.48)%,呈浓度及时问依赖性。24h的细胞凋亡率分别为(4.17.4-0.55)%、(8.22±0.70)%、(14.10±0.44)%;48h的细胞凋亡率为(11.19±0.47)%、(23.01±0.53)%、(28.10±0.52)%,均显著高于对照组的(0.09±0.12)%(P〈0.05)。结论MMI-166以浓度和时间依赖性抑制胰腺癌SW1990细胞增殖,诱导细胞凋亡。Objective To investigate the effects of MMI-166 on the proliferation and apoptosis of human pancreatic cancer SW1990 cells. Methods MMI-166 of different concentrations (25, 50, 100 μg/ml) were used to treat human pancreatic cancer SW1990 cell for 24, 48 h. Effect of MMI-166 on cell proliferation was detected by 3-(4,5-dimethyl-2-thiazole)-2-5-biphenly-tetrazole bromide (MTY) method and effect on cell apoptosis was tested by Annexin V-PI method and flow cytometry (FCM). Results Twenty-four hours after MMI-166 treatment of different concentrations (25, 50, 100 μg/ml), the inhibitory rates of the cells were (34.23 ±3.87)%, (44.81 ±2.01)%, (53.91± 1.74)%, and the corresponding values were (39.95 ± 1.83) % , ( 52.26 ± 3.46 ) % , ( 63.20 ± 2.48 ) % at 48 h, which suggested a time-and concentration- dependent manner. The cell' s apoptosis rates were ( 11.19 ± 0.47 ) % , ( 23.01 ± 0.53 ) % , ( 28.10 ± 0.52)% at 24 h, and the corresponding values were (11.19±0.47)%, (23.01 ±0.53)%, (28.10± 0. 52 ) % at 48 h, which were significantly higher than those in control group [ (0.09 ± 0. 12) %, P 〈 0. 05 ]. Conclusions MMI-166 can inhibit proliferation and induce apoptosis of human pancreatic SW1990 cell in a time- and concentration-dependent manner.
