MEN1 and cholangiocarcinoma: Nevertheless, Ehrlich L et al. [78] confirmed that miR-24 negatively regulates menin expression in the liver, through in vitro expression evaluations in intrahepatic and extrahepatic cholangiocarcinoma cell lines (Mz-ChA-1, TFK-1, SG231, CCLP, HuCCT-1, and HuH-28) and a nonmalignant human intrahepatic biliary line (H69), demonstrating that miR-24 inhibition decreases cholangiocarcinoma proliferation via increasing menin expression.
