摘要 目的观察非小细胞肺癌组织中let-7、K-ras基因的表达变化,并探讨其意义。方法采用实时定量PCR技术检测30例非小细胞肺癌组织及其癌旁正常组织中的let-7、K-ras基因。结果 let-7基因在非小细胞肺癌组织中的表达量为0.761 6±0.388 3,低于癌旁正常组织的2.279 0±1.163 1(P<0.01),K-ras基因在非小细胞肺癌组织中的表达量为3.296 6±1.328 4,高于癌旁正常组织的1.387 3±0.681 2(P<0.01)。非小细胞肺癌组织中let-7与K-ras基因的表达呈负相关(r=-0.834 3,P<0.01)。结论非小细胞肺癌组织中let-7表达下降而K-ras基因表达上升,两者共同参与了非小细胞肺癌的发生、发展过程。
