摘要
线粒体在细胞能量代谢 ,氧自由基生成和细胞凋亡中发挥重要作用。肿瘤细胞的线粒体功能障碍是其重要的特征之一。正常细胞线粒体在分子、生化、代谢和遗传水平上明显区别于癌细胞。本综述重点讨论线粒体DNA的损伤与突变在细胞癌变中的地位和可能的作用机制。
Mitochondria play important roles in cellular energy metabolism,free radical generation and apoptosis. Mitochondrial dysfunction is one of the most profound features of cancer cells. Several distinct differences between the mitochondria of normal cells and cancer cells have been observed at the molecular,biochemical,metabolic and genetic levels. In this article,we review the relationship between mitochondrial DNA (mtDNA) and carcinogenesis of cancer cells. The possible mechanisms are also discussed.
