miR-137 is significantly downregulated in cholangiocarcinoma. (A) The expression of miR-137 was detected in 29 cholangiocarcinoma tissues and 20 adjacent non-tumor tissues using reverse transcription-quantitative PCR. (B) The expression of miR-137 in the cholangiocarcinoma cell lines TFK-1, HuCCT1, RBE and QBC939 and HIBEpiCs was detected using reverse transcription-quantitative PCR. **P<0.01. miR, microRNA; HIBEpiCs, human intrahepatic biliary epithelial cells.
