TOLLIP and hepatocellular carcinoma: In the present study, we investigated the expression profiles of circRNAs in HCC tissues by analysis of microarray datasets from the Gene Expression Omnibus (GEO) database and identified a novel abnormally expressed circRNA termed circTOLLIP (circBase ID: hsa_circ_0008301), which is derived generated from exons of Toll-interacting protein (TOLLIP).
