Hao Li, Zun‐Qiang Zhou, Zhang‐Ru Yang, Da‐Nian Tong, Jiao Guan, Bao‐Jie Shi, Jia Nie, Xian‐Ting Ding, Bin Li, Guang‐Wen Zhou, Zheng‐Yun Zhang – 14 February 2017 – Current treatment of intrahepatic cholangiocarcinoma (ICC) remains ineffective because knowledge of ICC carcinogenesis is unclear. Increasing evidence suggests that microRNAs (miRNAs), including miR‐191, play an important role in tumorigenesis; but expression and biological functions of miR‐191 in ICC remain to be established. This study investigated the functions and underlying mechanisms of miR‐191 in ICC.
