CircRNAs: A novel strategy in diagnosis and treatment of thyroid cancer

Abstract

Abstract: Thyroid cancer is one of the most frequent cancers globally and its incidence has risen recently. Clinical behavior of thyroid cancer includes a wide range from benign tumors to very invasive malignant tumors. Thus, precious diagnostic activities before therapeutic work are required. Circular RNAs (circRNAs) along with microRNAs (miRNAs) and long non-coding RNAs (lncRNAs) are known as non-coding RNAs (ncRNAs). Large amounts of investigations have been indicated that circRNAs can participate in multiple cellular processes, especially in tumorigenesis. Furthermore, circRNAs are stable in blood or plasma as well as they are specific in different tissues. Therefore, they could serve as a potential diagnostic biomarker for cancer cells. Limited studies investigated the role of circRNAs in some processes involved in thyroid cancer. in this review, we summarized the current evidence on the potential clinical involvement of circRNAs in thyroid cancer.
