摘要:

目的: 探讨线粒体DNA中D-loop区突变在非小细胞肺癌中的意义及其临床应用的可能性。方法:提取20例非小细胞肺癌患者的癌组织及癌旁组织细胞的线粒体DNA (mtDNA),PCR扩增D-loop区并进行测序,然后以人类基因组中的D-loop区序列为对照,分析基因突变。结果:20例非小细胞肺癌患者的癌组织及癌旁组织mtDNA的D-loop区均发生突变,总突变数265个,其中癌组织特异性突变69个,癌旁组织特异性突变96个,共同突变50个,突变主要集中于D-loop的HVRII区。结论:线粒体DNA中D-loop区的突变主要集中于HVRII区,在非小细胞肺癌的发生发展中可能有重要作用。

Abstract:

OBJECTIVE: To study the role of mitochondrial DNA (mtDNA) mutations in D-loop region in non-small cell lung cancer patient’s and its possible clinical application. METHODS:The mtDNA of both cancer and paracancerous tissue cells of 20 non-small cell lung cancer patients was extracted, the D-loop region propagated by PCR sequenced,and mutations taking the mtDNA D-loop sequences of the human genome as control were analyzed. RESULTS:Mutations were found in the sequence of the cancer and paracancerous tissue cells of all 20 cases of non-small cell lung cancers. Among the 265 mutations there were 69 specific mutations of cancer tissue,96 specific mutations of paracancerous tissue and 50 common mutations. CONCLUSION:The mutations of D-loop region of mtDNA occurred mainly in HVRII region,and it may play an important role in the development of non-small cell lung cancer.
