title: Immunohistochemical analysis of heme oxygenase-I in rat liver after ischemia.
abstract: Total hepatic ischemia was induced by clamping the hepatic artery, portal vein, and bile duct. After 15 min hepatic ischemia, we examined a time course of the changes in the steady-state levels of heme oxygenase-1 (HO-1) mRNA and protein in the livers. The levels of HO-1 mRNA was transiently induced and peaked at 4 h after the start of reperfusion. In addition, a pattern of the time course of HO-1 protein levels was similar to that of HO-1 mRNA levels. Immunohistochemical analysis clearly showed that the localization of HO-1 protein induced by hepatic ischemia was restricted to the hepatocytes in the pericentral vein.
