NOLC1 and neoplasm: Nude mice xenograft assays demonstrated that the tumorigenicity was inhibited in mice injected with circ-NOLC1-downregulated A2780 cells (Fig. 5D; p < 0.05) compared with that in the control group (Fig. 5A, B), and the tumor volumes were smaller in the circ-NOLC1 downregulation group (Fig. 5C; p < 0.05).
