Aspartyl beta-hydroxylase immunoreactivity in hepatocellular carcinoma and nontumoros liver tissue. Nontumoros hepatic parenchyma was negative or weakly focal positive (a); High immunoreactivity was detected on the cell surface membranes (b), in the cytoplasm (c), and in membranes and perinuclear zones (d) in hepatocellular carcinoma.
