Knowledge of early molecular events occurring upon ischemia/reperfusion (I/R) during liver transplantation (LT) 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 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.

Abstract
Knowledge of early molecular events occurring upon ischemia/reperfusion (I/R) during liver transplantation (LT) 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 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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
