Liver transplantation is the only therapeutic strategy for many inherited and acquired diseases. The formation of reactive oxygen species following ischemia/reperfusion is a cause of hepatocellular injury during transplantation. This report describes the therapeutic application of mitochondrial superoxide dismutase gene transfer to the liver for acute ischemia/reperfusion injury. Recombinant adenoviral expression of mitochondrial superoxide dismutase in mouse liver prior to lobar ischemia/reperfusion significantly reduced acute liver damage and associated redox activation of both NF-kappaB and AP1. These immediate early transcription factors represent common pathways by which cells respond to environmental stress. This work provides the foundation for redox-mediated gene therapies directed at ameliorating ischemia/reperfusion injury and associated acute rejection in orthotopic liver transplantation.
