Promising Gene Therapy Using an Adenovirus Vector Carrying REIC/Dkk-3 Gene for the Treatment of Biliary Cancer

Background: We previously demonstrated that the reduced expression in immortalized cells (REIC)/dikkopf-3 (Dkk-3) gene was downregulated in various malignant tumors, and that an adenovirus vector carrying the REIC/Dkk-3 gene, termed Ad-REIC induced cancer-selective apoptosis in pancreatic cancer and hepatocellular carcinoma. Objective: In this study, we examined the therapeutic effects of Ad-REIC in biliary cancer using a second- generation...
