A, Down‐regulation of cyclin D1 (CCND1) greatly suppressed cell proliferation, which was otherwise up‐regulated by miR‐338‐3p inhibitor in both FTC‐133 cells and B‐CPAP cells compared with negative control (NC) group; (B,C) Cell migration assay showed that knock‐down of CCND1 greatly inhibited cell migration, which was instead promoted with miR‐338‐3p inhibitor in both FTC‐133 cells and B‐CPAP cells compared with NC group. **P < 0.01, compared with NC group; ^## P < 0.01, compared with inhibitor group
