Abstract:MicroRNAs (miRNAs) are tiny, endogenously expressed noncoding RNAs that act as the posttranscriptional regulators of gene expression, and play very important roles in cell proliferation, differentiation and apoptosis as well as in cancer occurrence and development. In this paper, the authors overview the recent advances of miRNAs involvement in cholangiocarcinoma, focusing on miR-21, miR-370, let-7 family, miR-373, miR-200 family, miR-29b, miR-204 and miR-320.
