中文摘要
我们目前的研究表明,线粒体功能障碍会导致氧相关的基因组DNA损伤。由于氧是氧化应激的基本因素,而氧化应激是基因组不稳定的原因,我们一直在研究在不同的癌症模型中调节环境氧对新生肿瘤发生(例如淋巴瘤或结肠息肉形成)的影响。由于氧化应激也与炎症有关,我们一直在研究其对动脉粥样硬化的影响。这些研究的目的是为环境氧在疾病发病机制中的重要性提供基本的实验证据,并获得有助于开发针对人类疾病的两大主要原因的新预防策略的见解。
英文摘要
Our current studies suggest mitochondrial dysfunction causes oxygen-associated genomic DNA damage. Because oxygen serves as an essential factor for oxidative stress, a cause of genomic instability, we have been examining the effect of modulating ambient oxygen on de novo tumorigenesis (e.g., lymphoma or colon polyp formation) in different cancer models. As oxidative stress is also involved in inflammation, we have been examining its effect on atherosclerosis. The goals of these investigations are to provide basic experimental evidence for the importance of ambient oxygen on disease pathogenesis and to obtain insights useful for developing new preventive strategies against the two major causes of human diseases.
