ObjectiveTo summarize the role of circular RNA (circRNAs) in thyroid papillary carcinoma (PTC) and the emphasis of future research.MethodRelevant literatures in recent years about the biological function of circRNA and its role in PTC were reviewed.ResultscircRNAs had abnormal expression in PTC tissues. Besides, by working as miRNA sponges or interacting with RNA-binding proteins, circRNAs regulated the expression of proteins that were associated with cell proliferation, apoptosis, invasion, and metastasis, which could affect the biological characteristics of tumor cells.ConclusioncircRNAs are expected to be the biomarkers for early diagnosis of PTC or potential targets for PTC therapy and provid therapeutic bases to prevent PTC.
