MMP-9 and aortic aneurysms—developing a model. The long-term goal of the research
group at Northwestern University is to understand the role of MMP-9 in the pathogenesis of
AAAs. Preliminary studies have demonstrated a significant correlation between aneurysm
size and aortic wall expression of MMP-9 messenger RNA (mRNA), and patients with AAAs
also exhibit elevated plasma levels of MMP-9. On the basis of these studies, the
investigators proposed that the mechanisms of arterial wall repair are abnormal in patients …
