The tumours of mice in the si-circ_0068871 group were significantly decreased in size and volume compared to those in the control group (Fig. 6a‐c), and the expression of FGFR3 in the tumours of the si-circ_0068871 group was decreased, as indicated by the results of Western blotting and IHC (Fig. 6d, e). Here, FGFR3 is linked to neoplasm.
