Abstract

背景与目的已有的研究表明:线粒体DNA(mitochondrial DNA, mtDNA)突变和拷贝数的改变和肿瘤有着密切联系;大多数实体性肿瘤中mtDNA拷贝数有明显降低。本研究旨在探讨线粒体基因组含量的改变和原发性非小细胞肺癌(non-small cell lung cancer, NSCLC)的关系。方法通过实时荧光定量PCR,对肺癌及相对应的癌旁肺组织mtDNA的含量进行精确定量(拷贝数/细胞)。结果肺癌组织mtDNA的平均拷贝数/细胞为395±125,而相对应的正常肺组织为733±196,前者明显低于后者(P < 0.001)。肺癌mtDNA含量的改变与患者性别、年龄、是否吸烟及肿瘤的病理类型无关(P > 0.05)。结论mtDNA含量的改变与NSCLC的发生发展密切相关,同时也可能影响其治疗和预后。
