Outline of Final Research Achievements

Hypoxic stimuli play important roles in the development of cardiovascular diseases such as ischemic heart disease, atherosclerosis. In the present study, to clarify the role of ER oxidoreductin-1 (Ero1), a major ER oxidase, in the development of abdominal aortic aneurysm, we have tried and succeeded to create Ero1 knockout mice by ES trap method. Interestingly, we found that Ero1 expression increased in human samples from abdominal aortic aneurysm. We also found that continuous infusion of angiotensin II induced abdominal aortic aneurysm in Ero1 knockout, but not normal, mice, suggesting that Ero1 plays an important role in the development of abdominal aortic aneurysm.
