Liver transplant: adenosine metabolism and apoptosis

Apoptosis and necrosis coexist in ischemia-reperfusion (I/R) injury following organ transplant. During experimental liver transplant we evidenced a deep alteration in energy and antioxidant status. The activity of purine catabolic enzymes was also altered. Caspase-3 (C-3), protein tyrosine phosphatase (PTP) showed significative alterations that lead to DNA fragmentation. These findings could be of interest in new potential strategy to prevent and treat I/R injury.
