Evaluation of tumor drug resistance with Ku80 mRNA expression in human lung cancer / 中国免疫学杂志

Objective:To study the different Ku80 mRNA expression in normal lung tissue group, lung cancer group(non small cell lung cancer) without chemotherapy, lung cancer group with multiple chemotherapy(n≥2),to evaluate the relationship of tumor drug resistance with Ku80 mRNA expression in human lung cancer.Methods:The lung tissue gene level of Ku80 mRNA was measured by reverse transcription polymerase chain reaction(RT-PCR) in 25 normal lung tissues, 51 lung cancer tissue,taking ?-actin as inner reference.The data were analyzed by SPSS software.Results:Ku80 mRNA expression in normal lung tissue compared to lung cancer group without chemotherapy, lung cancer group with multiple chemotherapy(n≥2) had statistic significant meaning,respectively P
