Circ0097009 functions as a sponge for microRNA-1261 (miR-1261). (A) Predicted direct binding sites of miR-1261 within the circ0097009 sequence. (B) Expression level of miR-1261 in the LO2 cell line and hepatocellular carcinoma cell lines. (C) Relative luciferase activity of HepG2 cells co-transfected with the miR-1261 mimics and the luciferase reporter vector containing the wild-type or mutant circ0097009 sequence. (D) MS2-based RNA immunoprecipitation assay in HepG2 cells transfected with MS2bs-circ0097009, MS2bs-circ0097009-mt, or MS2bs-Rluc. **P<0.01.
