摘要:

目的:研究新型β2受体激动剂川丁特罗(trantinterol)对细胞色素P450酶(CYP450)mRNA表达的影响,为临床合并用药提供理论依据。方法:人肝癌细胞(HepG2)中分别加入浓度为2.4、12、60、300、1 200和4 800 ng/L 的川丁特罗,MTT法检测药物作用下的细胞增殖。采用RT-PCR法检测HepG2细胞中CYP1A1、CYP2E1和CYP3A5亚型的mRNA表达量。结果:不同浓度的川丁特罗均未抑制HepG2细胞的增殖 (P>0.05)。与对照组比较,川丁特罗给药组CYP3A5和CYP2E1 mRNA表达无明显变化,而CYP1A1 mRNA表达水平明显降低(P<0.01)。结论:川丁特罗能明显抑制HepG2细胞中CYP1A1 mRNA表达,而对CYP3A5和CYP2E1表达无影响。

Abstract:

Abstract:Objective To study the effect of trantinterol,a potent and highly selective  β2 receptor  agonist,on the cytochrome P450 enzymes (CYP450) mRNA expression and provide a theoretical basis for clinical drug combination.Methods  The cell proliferation of HepG2 cells treated with  2.4,12,60,300,1 200 and 4 800 ng/L  trantinterol was analyzed by MTT.The mRNA expression levels of CYP1A1,CYP2E1 and CYP3A5 in HepG2 cells were examined using the real-time quantitative reverse-transcriptase polymerase chain reaction in human hepatoma HepG2 cells.Results Different concentrations of trantinterol didn’[KG-*3]t inhibit the proliferation of HepG2 cells (P>0.05).Compared with control group,the mRNA expressions of CYP2E1 and CYP3A5 in trantinterol groups had no change,while the mRNA expression of CYP1A1 was inhibited (P<0.01).Conclusion Exposure of HepG2 cells to trantinterol has no effect on the mRNA expressions of CYP2E1 and CYP3A5 but inhibit the mRNA expression of CYP1A1.

Key words: trantinterol, cytochrome P450, HepG2 cell; , real-time quantitative polymerase chain reaction
