ABSTRACT
ObjectiveTo identify the proteins presented variation during ischemia/reperfusion injury (I/RI) in liver transplantation (LT).MethodsAt Mar.2009,a total of nine liver sample tissues,three samples obtained from each donor liver at three different time points,were studied.The time points were as follows(1) the time point immediately after donor liver was harvested (T1) ; (2) the time point just before the anastomosis of hepatic artery and potal vein (T2),during this time period the donor liver was kept in ice cold and transported,then back-table prepared,during time from T1 to T2,ischemia injury occurred; (3) the time after donor reconnected to the recipient (T3),during which the donor liver was subjected to reperfusion injury.The three time points represent normal control,ischemia injury,and reperfusion injury respectively.By using method of 2DE-MALDI-TOF and mass-spectrum,the differential expression of these protein at T1,T2,and T3 time point were compared.ResultsFrom the 1580 proteins that were isolated,19 ischemia/reperfusion injury (I/RI)-related proteins that varied markedly from time point T1 to T2 and from time point T2 to T3 were identified.They were metabolic enzyme,molecular chaperone,redoxase,cytoskeleton protein,signal transduction protein,and binding protein,respectively.The character of each protein was further analized based on their functions.ConclusionsFor the first time,we detected the protein related to I/RI during LT.We obtained independent proteomics information of ischemia injury,and reperfusion injury,respectively.Further functional analyses of these proteins may improve the understanding of the critical biological processes during I/RI.Medicine intervention on the I/RI-related proteins may result in improved survival of the recipients.
