摘要: 人8-羟基鸟嘌呤DNA糖苷酶1(hOGG1)功能异常与肺癌等癌症发生发展密切相关,hOGG1基因多态性可能会改变酶的活性,从而影响个体损伤DNA的修复能力,促进癌变。hOGG1等DNA修复基因单核苷酸多态性联合效应提高人群肺癌的易感性。hOGG1参与调节肿瘤细胞的线粒体呼吸功能并影响肿瘤细胞生长。

Abstract: Dysfunction of the human 8oxoguanine DNA glycosylase (hOGG1) is closely related to development of lung neoplasms and other cancers. Polymorphisms in hOGG1 gene may alter glycosylase activity, thereby affect its repair capacity to the damaged DNA, contributing  to carcinogenesis. Joint effects of hOGG1 and other DNA repair gene SNPs  have showed complex genegene interactions may significantly contribute to people′s lung cancer susceptibility. HOGG1 plays an important role in maintaining mitochondrial respiration thus affects tumor cell growth.

Key words: Lung neoplasms, DNA, mitochondrial, hOGG1
