非小细胞肺癌中SLC22A18的表达及其临床意义

背景与目的已有的研究证明：多药耐药（multidrug resistance,MDR）是肺癌化疗失败的主要原因,研究MDR的产生机制对于提高肺癌的化疗疗效有着重要的临床意义。SLC22A18基因编码蛋白与跨膜转运体相似,影响药物敏感性、细胞代谢和生长,可能在肺癌MDR的产生中发挥一定作用。本研究旨在检测SLC22A18在非小细胞肺癌（non-small cell lung cancer,NSCLC）及相应正常组织中的表达,并分析其与组织学类型、分级和TNM分期的关系。方法应用免疫组化EnVinsion法检测SLC22A18在96例NSCLC及正常组织中的表达,结果用统计学软件SPSS17.0进...

Summary:	背景与目的已有的研究证明：多药耐药（multidrug resistance,MDR）是肺癌化疗失败的主要原因,研究MDR的产生机制对于提高肺癌的化疗疗效有着重要的临床意义。SLC22A18基因编码蛋白与跨膜转运体相似,影响药物敏感性、细胞代谢和生长,可能在肺癌MDR的产生中发挥一定作用。本研究旨在检测SLC22A18在非小细胞肺癌（non-small cell lung cancer,NSCLC）及相应正常组织中的表达,并分析其与组织学类型、分级和TNM分期的关系。方法应用免疫组化EnVinsion法检测SLC22A18在96例NSCLC及正常组织中的表达,结果用统计学软件SPSS17.0进行分析。结果 SLC22A18主要定位于胞膜和胞质中。SLC22A18在NSCLC中的表达高于正常组织,差异明显（P〈0.01）,鳞癌、腺癌阳性率分别为68.0%和78.2%,差异性有统计学意义（P〈0.05）。鳞癌、腺癌不同病理分级、TNM分期间SLC22A18表达差异性均有统计学意义,癌组织分化越差、分期越晚,SLC22A18表达越高（P〈0.05）。结论 SLC22A18在NSCLC组织中高表达,表达的高低与组织学类型、分级、TNM分期有关,本研究为进一步探讨SLC22A18在肿瘤中的表达及可能的耐药作用提供了实验依据。

Research on emergence mechanisms of MDR has great clinical signi cance in improving the curative e ciency of lung cancer chemotherapy. Proteins encoded by the SLC22A18 gene, which is similar to the transmembrane transporter, may in uence the sensitivity of chemotherapeutics as well as the metabolism and growth of cells. In addition, these proteins probably have some e ect on the development of lung cancer MDR. e aim of the present study is to investigate the expression of SLC22A18 protein in non-small cell lung cancer （NSCLC） as well as in corresponding normal lung tissue. Furthermore, the relationship between SLC22A18 e
