Hepatic ischemia/reperfusion (I/R) injury is an inevitable consequence during liver surgery. I/R injury induces serious hepatic dysfunction and failure. In this study, we identified proteins that were differentially expressed between sham and I/R injured livers. Animals were subjected to hepatic ischemia for 1 hr and were sacrificed at 3hr after reperfusion. Serum ALT and AST levels were significantly increased in I/R-operated animals compared to those of sham-operated animals. Ischemic hepatic lobes of I/R-operated animals showed the hepatic lesion with unclear condensation and sinusoidal congestion. Proteins from hepatic tissue were separated using two dimensional gel electrophosresis. Protein spots with a greater than 2.5-fold change in intensity were identified by mass spectrometry. Among these proteins, glutaredoxin-3, peroxiredoxin-3, glyoxalase I, spermidine synthase, dynamin-1-like protein, annexin A4, eukaryotic initiation factor 3, eukaryotic initiation factor 4A-I, 26S proteasome, proteasome alpha 1, and proteasome beta 4 levels were significantly decreased in I/R-operated animals compared to those of sham-operated animals. These proteins are related to protein synthesis, cellular growth and stabilization, anti-oxidant action. Moreover, Western blot analysis confirmed that dynamin-1-like protein levels were decreased in I/R-operated animals. Our results suggest that hepatic I/R induces the hepatic cells damage by regulation of several proteins.
