Abstract excerpt
The mechanisms of carcinogenesis in intrahepatic cholangiocarcinoma (ICC) are not well characterized although alterations in several oncogenes and onco-suppressor genes have been reported to occur in ICC. In the present study, we focused on alterations in the Wnt signaling components and target genes by analyzing 24 surgically resected samples of ICC. Immunohistochemical analysis of beta-catenin showed positive...
