Background/Aims: The human proto-oncogene c-erbB-2 (also called HER-2/neu) is located on chromosome 17q21-22. There have been no studies on gene amplification or mRNA expression of c-erbB-2 in human intrahepatic cholangiocarcinoma (CC) hitherto.Methods: We investigated c-erbB-2 gene amplification by fluorescence in situ hybridization (FISH), c-erbB2 mRNA expression by ISH, and c-erbB-2 protein expression...
Background/Aims: Cell adhesion molecules play an important role in the morphogenesis of developing organs. However, little is known about their expression during intrahepatic bile duct development.Methods: We immunohistochemically investigated the expression of E-cadherin (E-Cad), alpha-catenin (A-Cat) and beta-catenin (B-Cat) during human intrahepatic bile duct development, using 31 fetal livers...
