中文摘要
我们以前的研究表明,线粒体功能障碍会导致DNA氧化损伤,并有助于肿瘤的发生。氧化应激的一个主要因素是环境氧,它是产生活性氧物种的基本底物。环境和遗传方法将被用来调节氧化还原动态平衡,并确定它们对能量代谢、肿瘤发生和心血管功能的影响。我们还在研究细胞在氧化或其他细胞应激条件下生存的适应机制。我们最近已经证明了保持线粒体DNA对预防阿霉素引起的心肌病的重要性,并正在研究新的诊断和预防策略。
英文摘要
Our previous studies have suggested that mitochondrial dysfunction causes oxidative DNA damage and contributes to tumorigenesis. A major contributing factor to oxidative stress is ambient oxygen which is the essential substrate for reactive oxygen species generation. Environmental and genetic methods will be used to modulate redox homeostasis and to determine their effect on energy metabolism, tumorigenesis, and cardiovascular function. We are also examining the adaptive mechanisms by which cells can survive under oxidative or other cellular stress conditions. We have recently demonstrated the importance of maintaining mtDNA to prevent doxorubicin-induced cardiomyopathy and are investigating new strategies for diagnosis and prevention.
