| Research Abstract |
The aging-related arterial medial change (arterial aging) causes heart failure and chronic kidney disease in the elderly. Aortic dissection may arise from some unidentified anomaly of the aortic media. The purpose of this study is to analyze the changes of arterial medial constitutive proteins in arterial aging and aortic dissection using the comprehensive proteome analysis. In the cases of aortic dissection, there were increase and decrease of smooth muscle contraction proteins, increase of stress response proteins, and decrease of extracellular matrix proteins. Arterial aging was associated with decrease of smooth muscle actin, increase of stress response proteins, and increase of proteins of extracellular glycosaminoglycans. We successfully identified the specific changes of arterial medial constitutive proteins seen in arterial aging and aortic dissection.
