Papillary thyroid carcinoma (PTC) accounts for >80% of thyroid cancer cases with an increasing incidence worldwide. Despite improved diagnostic strategies and treatments, certain aggressive characteristics of PTC render the identification of alternative therapeutic approaches necessary. Circular RNAs (circRNAs) are a novel class of long non-coding RNAs (lncRNAs) containing a closed-loop structure with a covalent linkage of 3'-5' ends. Thus, they are more stable and resistant to RNA exonucleases. A significant number of recent studies on circRNAs have illustrated the dysregulated expression of these biomarkers in various types of tumors. However, the function of these non-coding RNAs and downstream mechanisms in PTC have not yet been entirely identified. In the present review article, the authors aim to discuss and summarize the functions and roles of circRNAs, including their expression profiles, potential targets and regulatory mechanisms previously recognized in PTC.
