Differential expression pattern of heme oxygenase-1/heat shock protein 32 and nitric oxide synthase-II and their impact on liver injury in a rat model of hemorrhage and resuscitation

Abstract

These data suggest that HO-1/HSP32, but not the alternative cyclic guanosine monophosphate-generating enzyme NOS-II, is induced after hemorrhage and resuscitation and protects against hepatocellular injury. Both metabolites generated by the heme oxygenase pathway, e.g., carbon monoxide (a vasodilator) and biliverdin (an antioxidant) seem to contribute to the salutary effects of induction of HO-1/HSP32.
