Anti-Inflammatory Effects of AAV-Mediated TIMP-1 Gene Transfer in Hepatic Ischemia-Reperfusion Injury.
S. Duarte, T. Fujii, G. Lipshutz, R. Busuttil, A. Coito.
The Dumont-UCLA Transplant Center, Los Angeles.
Matrix metalloproteinase-9 (MMP-9) is a key mediator of leukocyte migration across vascular barriers in hepatic ischemia/reperfusion injury (IRI). Tissue inhibitor of metalloproteinase1 (TIMP-1) is the…

Hif-1α Stabilization in the Recipient Accelerates Cardiac Allograft Rejection.
Z. Ilyas, M. DeBerge, S. Dehn, J.-J. Wang, Z. Zhang, E. Thorp, M. Ansari.
Northwestern University, Chicago.
Introduction: Increased Hif-1α mRNA expression in deceased-donor organ transplant tissue prior to or soon after transplantation significantly correlated with primary graft dysfunction. HIF-1α is positioned…
