Popis: Background/Aim: Cholangiocarcinoma (CCA) is a type of liver cancer originating from bile duct epithelium which has an unfavorable prognosis. Therefore, novel prognostic markers and effective therapeutic regimens are required. Opioid-binding protein/cell adhesion molecule-like (OPCML) is a tumor-suppressor protein that suppresses CCA cell proliferation via AXL receptor tyrosine kinase/signal transducer and activator of transcription 3 (AXL/STAT3) inactivation. However, this association in clinical samples remains unknown. We aimed to determine OPCML and AXL expression and investigate their association with clinicopathological features in patients with CCA. In addition, we also addressed whether OPCML enhanced the sensitivity of CCA cells to AXL inhibitor R428 in vitro. Materials and Methods: The expression of OPCML and AXL was determined by immunohistochemistry in 90 CCA tissue samples. The study of CCA cell line sensitivity to R428 was performed by cell viability assay. Results: The expression of OPCML was significantly lower while AXL expression was substantially higher in CCA than in adjacent normal tissue (p
