The role of NF-
B, the rapid response transcription factor for multiple genes, in cold ischemia/reperfusion (I/R) injury was examined after syngenic transplantation of liver grafts. Lewis rat recipients were sacrificed 1-48 hours after reperfusion of three different liver grafts: 1) uninfected control, 2) infected ex-vivo with control adenoviral vector (AdEGFP), and 3) infected ex-vivo with AdI
B. In uninfected control livers, NF-
B was activated biphasically at 1-3 hours and 12 hours after reperfusion with AST levels of 4244±691 IU/L. The first peak of NF-
B activation associated with an increase of mRNA for TNF-
, IL1-ß and IL-10. AdEGFP-transfection resulted in similar outcomes. Interestingly, AdI
B-transfected liver grafts suffered more severe I/R injury (AST >9000 IU/L). Transfected I
B was detected in transplanted livers as early as 6 hours, and this correlated with the abrogation of the second, but not the first, peak of NF-
B activation at 12-48 hours and increased apoptosis. Thus, inhibition of the second wave of NF-
B activation in I
B transfected livers resulted in an increase of liver injury, suggesting that NF-
B may have a dual role during liver I/R injury.
