摘　　要：背景与目的:NK/T细胞淋巴瘤(natural killer/T cell lymphoma)疗效差,多药耐药(multidrug resistance,MDR)的产生是引起肿瘤产生耐药和化疗疗效降低及失败的原因之一,本文通过研究多药耐药相关蛋白4(ABCC4 multidrug resistance associated protein,ABCC4/MRP)基因和多药耐药相关蛋白5(ABCC5 multidrug resistance associated protein,ABCC5/MRP)基因在NK/T细胞淋巴瘤SNK-6、YTS细胞株和组织中的表达情况,结合临床疗效了解其与预后的关系。方法:应用实时荧光定量PCR(real-time PCR)技术和免疫组织化学法(immunohistochemistry,IHC)检测ABCC4/MRP4、ABCC5/MRP5基因mRNA和蛋白表达水平。结果:与正常NK细胞相比,ABCC4/MRP4、ABCC5/MRP5基因在SNK-6、YTS细胞株中高表达(P<0.05);与鼻炎组织相比,ABCC4/MRP4、ABCC5/MRP5基因在NK/T细胞淋巴瘤患者组织中高表达(P<0.05);ABCC4/MRP4、ABCC5/MRP5基因表达量的高低和临床疗效呈负相关(P<0.05)。结论:ABCC4/MRP4、ABCC5/MRP5基因及其表达蛋白影响NK/T细胞淋巴瘤的疗效。Background and purpose： Natural killer/T cell lymphoma in poor effects, the production of multidrug resistance is one of the reasons to reduce the chemotherapy effect or failure. This study aimed to discuss the multidrug resistance associated protein 4 （ABCC4/MRP4） gene and multidrug resistance associated protein 5 （ABCC5/ MRP5） gene expression in NK/T cell lymphoma SNK-6, YTS cell lines and NK/T cell lymphoma tissues, and the relationship between the level of ABCC4/MRP4, ABCC5/MRP5 gene expression and the clinical efficacy. Methods： Real-time fluorescence quantitative PCR （Real time-PCR） and immunohistochemical method （IHC） were used to detect the ABCC4/MRP4, ABCC5/MRP5 gene and protein expression. Results： Compared with the normal NK cells, ABCC4/ MRP4 and ABCC5/MRP5 gene in SNK-6, YTS cell lines were highly expressed （P〈0.05）; Compared with rhinitis tissues, the expression ofABCC4/MRP4, ABCC5/MRP5 gene was higher in the NK/T cell lymphoma tissues （P〈0.05）; The expression level of ABCC4/MRP4 and ABCC5/MRP5 gene was negative correlation with clinical efficacy （P〈0.05）. Conclusion： The expression of ABCC4/MRP4 and ABCC5/MRP5 gene affects the of clinical efficacy of NK/T cell lymphoma.
