The intragraft protein levels of Egr-1 were consistent using the mRNA levels (Fig. 4). As for ET-1 and ETA, the intragraft mRNA levels had been decreased significantly at 2 hours, 6 hours, and 24 hours right after liver transplantation (Fig. 3b, 3c; ET-1, 2 hours: 33.five versus 573 relative to basal level, P 0.034; 6 hours: 23 versus 392 relative to basal level, P 0.034; ETA, six hours: 157.five versus 266 relative to basal level, P 0.021;hours: 151 versus 356 relative to basal level, P 0.021). Even though over-expression of intracellular ET-1 was found in both groups at 30 minutes soon after reperfusion (Fig. 5a-1, 5a-3), it decreased drastically at 24 hours immediately after reperfusion inside the FK group (Fig. 5a-2, 5a-4). The intragraft mRNA levels of TNF- have been downregulated within the FK group at 6 hours and 24 hours soon after liver transplantation compared with the manage group (Fig. 3d; 6 hours: 218 versus 682 relative to basal level, P 0.038; 24 hours: 115.five versus 609.six relative to basal level, P 0.02). Each the intragraft mRNA level (Fig. 3e, 24 hours: 113.five versus 672.5 relative to basal level, P 0.04) and protein degree of MIP-2 (Fig. 4) have been down-regulated soon after FK 409 remedy. The intracellular protein expression of iNOS was significantly down-regulated at 24 hours soon after liver transplantation immediately after FK 409 remedy (Fig. 5b-2, 5b-4) compared with the manage group, while the comparable levels on the 2 groups have been discovered at 30 minutes following reperfusion (Fig. 5b-1, 5b-3).Intragraft Expression of HO-1, A20, Hsp-70, Interferon- -Inducible Protein-10 (IP-10), CXCR2, CXCR3, and IL-10: Prior Induction of Hsps and Anti-inflammatory GenesBoth the intragraft mRNA (Fig. 6a, 6b) and protein expressions (Figs. four and 7) of HO-1 and A20 had been up2004 Lippincott Williams WilkinsAnnals of Surgery Volume 240, Quantity 1, JulyFK409 Attenuates Modest Liver Graft InjuryFIGURE 7.

The peak in the mRNA degree of HO-1 in the FK group reached 5393 relative to basal level at six hours after reperfusion compared with the control group (781 relative to basal level, P 0.034) (Fig. 6a). The intragraft protein expression of HO-1 in the FK group was identified at its highest level at 24 hours immediately after reperfusion by Western blot (Fig. four). The intracellular protein expression by immunostaining demonstrated that over-expression of HO-1 was primarily identified in sinusoidal endothelial cel.
