Outline of Final Research Achievements |
The aim of this study is to investigate vascular calcification and its influence on changes in vascular inflammation in the process of aneurysm formation. Deletion of osteoprotegerin increased the severity of CaCl2-induced mouse abdominal aortic aneurysms. Both osteogenic and inflammatory factors were increased in the aneurysm wall, and vascular calcification is thought to influence vascular inflammation. Inhibition of Runx2 or NFκB using nucleic acid drug, decoy oligodeoxynucleotide, in the aneurysm wall protected AAA formation. This therapeutic approach might be useful to treat AAA.
