摘要:

目的: 通过研究选择性环氯化酶2(COX-2)抑制剂塞来昔布联合阿霉素(ADM)对乳腺癌MCF-7/ADM细胞株生长的作用,探讨塞来昔布的抗肿瘤作用。方法:MCF-7/ADM细胞加入不同浓度等倍稀释的ADM(0.05、0.10、0.20、0.40、0.80和1.60 mg/L)为对照组,MCF-7/ADM细胞加入无细胞的完全培养基为阴性对照组,在对照组的基础上联合应用10、20 μmol/L塞来昔布为实验组,各组细胞于24、48、72 h后采用CCK-8检测细胞生长抑制率。MCF-7/ADM细胞单加0.05 mg?L-1ADM及联合塞来昔布(10、20 μmol/L)处理后3 h收集细胞,采用流式细胞术检测细胞内ADM水平。结果:不同浓度ADM单药及联合塞来昔布(10和20 μmol/L) 作用于MCF-7/ADM 24、48和72 h后细胞生长受到抑制,实验组不同时间细胞生长抑制率均高于对照组(P<0.05),且20 μmol/L塞来昔布实验组细胞生长抑制率高于10 μmol?L-1塞来昔布实验组,差异具有统计学意义(P<0.05)。对照组24、48和72 h的细胞未见明显变化,但实验组细胞作用48和72 h后出现细胞改变及死亡,呈塞来昔布剂量依赖性。与对照组比较,塞来昔布实验组(10和20 μmol/L)细胞内ADM浓度升高(P<0.05);20 μmol/L塞来昔布实验组细胞内ADM浓度高于 10 μmol/L塞来昔布实验组(P<0.05)。结论:选择性COX-2抑制剂塞来昔布联合ADM可有效逆转乳腺癌ADM细胞株耐药。

Abstract:

Objective To study  the   inhibitory effect of celecoxib on proliferation of    adiramycin(ADM)-resistant  breast cancer cells MCF-7/ADM  and to discuss the anti-tumor effect of  celecoxib.Methods The MCF-7/ADM cells treated with different concentrations of ADM (0.05,0.10,0.20,0.40,0.80,1.60  mg/L) were used as  control groups;the MCF-7/ADM cells treated with cell-free complete medium were used as negative control group and   the cells treated with ADM and  10,20  μmol?L-1  celecoxib were  used as experiment group.The inhibitory rates of cells in various groups were detected by CCK-8 after 24,48 and 72 h.The MCF-7/ADM cells treated with  0.05  mg?L-1 ADM and  different concentrations of celecoxib (10 and 20  μmol/L) were collected 3 h  after treatment,the concentrations of ADM were detected by flow cytometry in various groups.Results The growth of cells were inhibited  24,48 and 72 h after treated  with different concentrations of ADM alone or combined with celecoxib (10 and 20  μmol/L). The inhibitory rates of cells in experiment group were higher than those in contronl group(P<0.05);the inhibitory rates in 20  μmol/Lcelecoxib experiment group were higher than those in 10  μmol/L celecoxib experiment group at  24,48 and 72 h (P<0.05).The cells in control groups changed little but the cells in experiment group changed a lot,which showed a celecoxib dose-dependent manner.Compared with control groups,the concentrations of ADM in the cells  in experiment group were increased(P<0.05).The concentration of ADM in the cells in 20 μmol/L celecoxib experiment was higher than that in 10 μmol/L celecoxib eperiment group(P<0.05).Conclusion The selective COX-2 inhibitor celecoxib combined with ADM can reverse the ADM resistance  of   breast cancer cell lines.
