RNF13 and hepatocellular carcinoma: In addition, circRNA expression profile in HBV-associated HCC tissues had been uncovered, and the top 5 upreguated circRNAs were hsa_circRNA_104351, hsa_circRNA_102814, circ-RNF13 (hsa_circRNA_103489), hsa_circRNA_102109, and hsa_circRNA_100381, comparing to adjacent non-tumorous tissues [10].
