S-Nitrosated human serum albumin (SNO-HSA) is useful in preventing liver ischemia/reperfusion injury, and SNO-HSA should thus be able to prevent cell injury during liver transplantation. However, the potential protective effect of SNO-HSA on a combination of cold and warm ischemia, which is obligatory when performing liver transplantation, has not been examined. Therefore, we evaluated the protective effect of SNO-HSA added to University of Wisconsin (UW) solution during cold or/and warm ischemia in situ and in vitro. First, we observed that apoptotic and necrotic cell death were increased during cold and warm ischemia, respectively. SNO-HSA, which possesses anti-apoptosis activity at low NO concentrations, can inhibit cold ischemia injury both in situ and in vitro. In contrast, SNO-HSA had no significant effect on warm liver ischemia injury which, however, can be reduced by UW solution. We also demonstrated that the cellular uptake of NO from SNO-HSA can occur during cold ischemia resulting in induction of heme oxygenase-1 within 3h of cold ischemia. Our results indicate that treatment with SNO-HSA or UW solution alone is not sufficient to inhibit liver injury during a period of both cold and warm ischemia. However, a combination of SNO-HSA and UW solution can be used to prevent the two types of ischemia. SNO-HSA-added UW solution could be very useful in transplantation, because the previously imposed constraints on preservation time can be removed. This is a great advantage in a situation as the present one with increased utilization of scarce donor organs for more recipients.
