Proteomic analysis of liver tissues subjected to early ischemia/reperfusion injury during human orthotopic liver transplantation RID D-8000-2011

Knowledge of early molecular events occurring upon ischemia/reperfusion (I/R) during liver transplantation (IT) is of great importance to improve the therapeutic intervention of surgical treatment. However, nowadays, few data are available on early protein targets of I/R injury. To 14 identify these proteins, we used a differential proteomics approach in the characterization human liver biopsies during I/R upon LT. Analyses were performed on nine donor livers during LT. By using 2-DE and MALDI-TOF MS, we identified 36 proteins which resulted significantly altered upon I/R injury. The majority of these proteins are functionally involved in lipid and energy metabolism, in different metabolic pathways, in redox signalling and in oxidative-stress response. Our data represent the first global approach in the study of I/R injury in liver.
