Our previous studies have suggested that mitochondrial dysfunction causes oxidative genomic DNA damage and contributes to tumorigenesis. Oxygen also serves as an essential substrate for reactive oxygen species formation but it is also essential by aerobic life. We are currently using environmental and genetic methods to modulate oxygen homeostasis and to examine their effect on energy metabolism and tumorigenesis. We are also examining adaptive mechanisms by which cells of neoplastic or cardiovascular origin survive under oxidative or other toxic stress conditions.

我们以前的研究表明，线粒体功能障碍导致氧化基因组DNA损伤，并有助于肿瘤的发生。 氧也是活性氧形成的重要底物，但它也是有氧生活所必需的。 我们目前正在使用环境和遗传的方法来调节氧稳态，并检查其对能量代谢和肿瘤发生的影响。 我们也在研究肿瘤或心血管起源的细胞在氧化或其他毒性应激条件下生存的适应机制。
