摘要
目的研究乳腺癌耐药蛋白(breast cancer resistance protein,BCRP)mRNA在非小细胞肺癌(non-small cell lung cancer,NSCLC)中的表达及临床意义。方法收集2010年4月~2011年6月新鲜非小细胞肺癌癌组织标本47例(实验组)、14例正常肺组织(对照组),采用实时定量PCR(real-time quantitative PCR)检测BCRP mRNA的表达,并分析其表达与NSCLC临床病理特征之间的关系。结果BCRP mRNA在正常肺组织中的表达为0.19±0.17,在癌组织中的表达为0.59±0.26,正常肺组织中的表达要低于肺癌组织,差异具有统计学意义(t=6.74,P〈0.001),BCRP mRNA的表达与肺癌的分化程度之间差异具有统计学意义(t=3.31,P=0.002),而与患者性别、年龄、组织学分型及临床分期之间差异无统计学意义(t=0.29~1.53,P〉0.05)。结论BCRPmRNA的高表达可能是NSCLC发生原发性耐药的一个重要原因,检测BCRPmRNA的表达水平可能对协助临床选择化疗方案有一定意义。
Objective To investigate the expression and evaluate clinical significances of breast cancer resistance protein (BCRP) in non-small cell lung cancer (NSCLC). Methods Collected fresh lung cancer of 47 cases (exprement group), 14 cases of normal lung tissue(control group) from April 2010 to June 2010. Real-time PCR method was used to detect the expression levels of BCRP mRNA in 14 normal tissues and 47 NSCLC cases. Results The expression of BCRP mRNA were 0. 594-0. 26 in NSCLC and 0. 19±0. 17 in normal lung tissues. The expressions of BCRP,GST-π in NSCLC were higher than those in normal tissues (t= 6.74, P〈0. 001 ). The expression of BCRP were not correlated with age, sex, histological types and clinical stage (t = 0.29 - 1.53, P〈 0.05). Respectively was correlated with differentiation (t = 3.31, P = 0. 002). Conclusion Higher expression of BCRP may play a major role in the intrinsic MDR of NSCLC,detection of BCRP expression may assist the guidance of individualized chemotherapy for patients with NSCLC.
