Abstract:

Circular RNA is a member of the non-coding RNA family and can participate in biological functions in many ways, such as cell proliferation, cell cycle, invasion and metastasis. Recent studies have shown that circular RNA can be involved in post transcriptional regulation by sponge miRNA and RNA binding proteins. Thus, it can affect DNA repair, apoptosis, proliferation, cell transport, and intracellular enzymes those mediate drug resistance, so as to play an important regulatory role in drug resistance. Moreover, it has been confirmed that interfering with the expression of circular RNA can improve the sensitivity of cancer to drugs, suggesting that circular RNA may provide a new target for the study of drug resistance of cancer.

Key words: MicroRNAs, Neoplasms, Drug resistance
