摘要
目的 评价异丙酚对人肺癌A549细胞凋亡及侵袭力的影响.方法 用RPMI-1640培养液将A549细胞株按2× 105个/ml细胞密度接种于96孔培养板和6孔培养板中,每孔分别为100μL和2 000μL,于5% CO2、饱和湿度37℃培养24h.采用随机数字表法,将其分为2组(n=60):二甲基亚砜组(DMSO组)和异丙酚组(P组).P组加入异丙酚终浓度100 μmol/L; DMSO组加入终浓度0.5%DMSO.于药物孵育24h时,采用HCS法检测caspase-3的表达水平,Western blot法检测基质金属蛋白酶(MMP)-2的表达水平,于药物孵育0.5、1、5h时,采用Western blot法检测细胞外蛋白调节激酶(ERK)1/2的表达水平.结果 与DMSO组比较,P组caspase-3表达上调,MMP-2表达下调(P<0.01),药物孵育0.5h时ERK1/2表达上调,1h时其表达下调(P<0.01),5h时差异无统计学意义(P>0.05).结论 异丙酚可促进人肺癌A549细胞凋亡,抑制A549细胞的侵袭力.
Objective To evaluate the effects of propofol on apoptosis and invasiveness of human lung cancer cell line A549 cells.Methods Human lung cancer cell line A549 were seeded onto 96-well plates (100 μl/well) and 6-well plates (2 000 μl/well) at a density of 2× 105 cells/ml,and cultured for24 h at 37 ℃ in 5% CO2.The cells were randomly divided into 2 groups (n =60 each) using a random number table:dimethyl sulfoxide (DMSO) group and propofol group (group P).In group P,propofol with the final concentration of 100 μmoYL was added.In group DMSO,0.5% DMSO with the final concentration of 0.5% was added.At 24 h of incubation with drugs,caspase-3 expression was detected by high content screening (HCS); the expression of matrix metalloproteinase (MMP-2) was detected by Western blot analysis.At 0.5,1 and 5 h of incubation,ERK1/2 expression was also measured using Western blot analysis.Results Compared with group DMSO,the expression of caspase-3 was up-regulated,the expression of MMP-2 was down-regulated,ERK1/2 expression was up-regulated at 0.5 of incubation and down-regulated at 1 h of incubation,and no significant change was found in ERK1/2 expression at 5 h of incubation in group P.Conclusion Propofol can promote apoptosis in A549 cells and inhibit invasiveness of human lung cancer cell line A549 cells.
