Potential roles of exosome non‑coding RNAs in cancer chemoresistance (Review)

Abstract
Multiple studies have demonstrated chemoresistance in multiple types of tumor, which limits the effectiveness of cancer treatments. Chemoresistance often contributes to cancer relapse. Non‑coding RNAs, are a group of regulatory RNAs, that are involved in tumor drug resistance. Exosomes, membranous vesicles secreted by cells, are reported to mediate cell‑to‑cell communication, including in cancer. Furthermore, exosomal non‑coding RNAs have been reported to mediate chemoresistance via exchange of biological information. In the present review, the main roles of exosomal non‑coding RNAs, including micro(mi) RNAs, long non‑coding (lnc) RNAs, and circular (circ) RNAs in cancer are described and their potential roles in chemoresistance in various types of cancer are also discussed.
