In a small cohort of patients from the Maastricht University Medical Center and Uniklinik RWTH Aachen, UGT8 and GAL3ST1 expression was measured by quantitative real-time PCR (qRT-PCR) in 6 tumor tissue and 10 tumor-distal liver specimens from patients with intrahepatic CCA. This evidence concerns the gene UGT8 and cholangiocarcinoma.
