Core Tip

Core Tip: The dysregulation and biological functions of circular ribonucleic acids (circRNAs) in colorectal cancer (CRC) have not been well elucidated. In this study, circ_0000375 and circ_0011536 were observed to be downregulated in CRC tissues, serum samples and cell lines. These 2 circRNAs were validated as biomarker candidates in tissues and serum samples with high diagnostic performance. Overexpression of circ_0000375 and circ_0011536 inhibited the growth, migration and invasion of CRC cells. Furthermore, miR-1182 and miR-1246 were upregulated in CRC tissues as target microRNA of circ_0000375 and circ_0011536, respectively. Overall, circ_0000375 and circ_0011536 may serve as diagnostic biomarkers and function as tumor suppressors in CRC.
