摘要
目的评价吗啡对顺铂治疗人肺腺癌细胞A549侵袭和迁移的影响。方法人肺腺癌细胞A549接种于培养板培养24h,随机分为五组:对照组(CON组)、顺铂组(CIS组)、0.3μg/ml吗啡+顺铂组(MT1组)、3μg/ml吗啡+顺铂组(MT2组)、30μg/ml吗啡+顺铂组(MT3组),顺铂浓度均为4μg/ml。加入相应浓度的药物后,采用Transwell法检测细胞侵袭能力,细胞划痕实验检测细胞迁移能力,Western blot检测细胞基质金属蛋白酶(MMP)-2、MMP-9、Ezrin蛋白和Fascin蛋白的表达。结果与CON组比较,其余四组肿瘤细胞侵袭和迁移能力明显降低,MT3组和CIS组MMP-2、MMP-9、Ezrin和Fascin表达明显下调(P<0.05)。与CIS组比较,MT1、MT2和MT3组肿瘤细胞侵袭和迁移能力增强,MT3组MMP-2、MMP-9、Ezrin和Fascin表达明显上调(P<0.05)。结论吗啡可剂量依赖性减弱顺铂对人肺腺癌细胞A549侵袭和迁移能力,MMP-2、MMP-9、Ezrin和Fascin表达上调是其可能机制之一。
Objective To investigate the effect of morphine combined with cisplatin on inva-sionon and migration of human lung adenocarcinoma cell A549.Methods Human lung adenocarcino-ma A549 cells were inoculated on cultured for 24 h,then were randomly divided into 5 groups：control group （group CON）,cisplatin group （group CIS）,morphine 0.3 μg/ml＋ cisplatin group （group MT1）,morphine 3 μg/ml＋ cisplatin group （group MT2）,morphine 30 μg/ml＋ cisplatin group （group MT3）.Cisplatin concentration was 4μg/ml.Each group was medicated immediately after 48 h incubation,invasion detection cells by Transwell assay,cell scratch assay cell migration ability, Western-blot detection of matrix metalloproteinase-2 （MMP-2）,the expression of MMP-9,Ezrin protein and Fascin protein.Results Compared with group CON,group CIS and morphine combined with cisplatin group reduced tumor cell invasion and migration ability,group MT3 and CIS down-reg-ulated MMP-2,MMP-9,Ezrin and Fascin expression （P〈0.05）.Compared with group CIS,com-bined with cisplatin group enhanced tumor cell invasion and migration ability group MT3,up-regula-ted MMP-2,MMP-9,Ezrin and Fascin expression （P〈0.05）.Conclusion Morphine may dose de-pendently reduce cisplatin on invasion and migration of human lung adenocarcinoma cell line A549, and up-regulation of MMP-2,MMP-9,Ezrin,Fascin expression is one of its possible mechanisms.
