Increased plasmin and serine proteinase activity during flow-induced intimal atrophy in baboon PTFE grafts.
High blood flow causes intimal atrophy and loss of extracellular matrix in PTFE aortoiliac grafts. We have investigated whether matrix-degrading proteinases are altered in this baboon model of atrophy using zymography, western analysis, and a versican degradation assay. After four days of high flow, urokinase was increased and plasminogen activator inhibitor-1 was decreased in the intima. Plasminogen was increased after seven days. Pro-matrix metalloproteinase (MMP)-2, activated MMP-2, and proMMP-9 levels were modestly increased by high flow at 7 days, whereas MMP-3 and tissue inhibitor of metalloproteinases-1 were not altered. Extracts of 4-day high-flow intimas degraded more 35S-methionine-labeled versican than low-flow intimal extracts, and this activity was inhibited by AEBSF, a serine proteinase inhibitor, and a plasmin antibody. In contrast, this activity was not inhibited by the MMP inhibitor, BB-94 (Batimastat). These data suggest that serine proteinases, including plasmin, may be largely responsible for extracellular matrix degradation in this primate model of flow-induced intimal atrophy.Richard D Kenagy, Jens W Fischer, Mark G Davies, Scott A Berceli, Suzanne M Hawkins, Thomas N Wight, Alexander W Clowes
