Abstract:
As an important member of the non-coding RNA family, circRNA is a kind of single-stranded RNA with a covalently closed loop structure without a polyadenylated acid tail and 5'-3' end, showing high stability, abundance and conservation across species characteristics. Recent studies have shown that circRNA plays an important role in many biological processes, including chemotherapy resistance and malignant progression. Exosomes are small extracellular phospholipid bilayer vesicles with a diameter of30-150 nm that are secreted by living cells. They can be used as carriers to encapsulate and transfer functional molecules. Exosomes are important mediators of communication between tumor cells and stromal cells. They can play a role in the transmission of chemoresistance by transferring circRNA. Aschemotherapy resistance is still a huge obstacle to the prognosis of cancer, the research of exosomalcircRNA-mediated tumor chemotherapy resistance is at the forefront of academic research, which is a blueocean with important significance. In this paper, we summarized the latest research progress in the aspects of exosome delivery of circRNA, the mechanism of exosome sorting non-coding RNA cargo, circRNA-mediated tumor chemotherapy resistance, exosome delivery of circRNA-mediated tumor chemotherapy resistance and its potential clinical application, which may provide a reference for the research of tumor chemotherapy resistance.
