摘要
Currently,extracellular vesicles and particularly exosomes have gained a lot of research interest due to their unique roles in several biological processes.Noncoding RNAs(microRNAs,long noncoding RNAs and circular RNAs)represent a class of functional RNA with distinct regulatory roles in tumorigenesis and cancer progression.Cholangiocarcinoma is a rare but highly aggressive type of malignancy that is very challenging to diagnose,especially in early stages;surgical resection still represents the sole potentially curative treatment option.Hence,there is an urgent need for the discovery of novel diagnostic and prognostic biomarkers.Hereby,we provide a comprehensive review of the most recent discoveries that focus on exosomal noncoding RNAs in cholangiocarcinoma with the aim to identify new molecular players that could be used as biomarkers and therapeutic targets.
