SiRNA-mediated inhibition of KIF22. (A) The expression of KIF22 in six GC cell lines was examined by Western blotting compared with one non-tumorigenic cell line. (B) KIF22 knockdown efficiencies were determined by Western blotting. (C) MTT assays displays decreased proliferation in MGC-803 after using KIF22 siRNA. (D) MTT assays display decreased proliferation in BGC-823 after using KIF22 siRNA. (E) Suppression of KIF22 decreased the colony formation ability of MGC-803 and BGC-823 cells. ∗P < 0.05 and +P < 0.01 for the SiRNA1 group vs. the control group, respectively. SiRNA: Small interfering RNA; KIF22: Kinesin superfamily protein 22; MTT: 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide.
