Knockdown of miR-133b in GES cells can promote cell proliferation and migration. (A) Inhibition of miR-133b in GES cells was confirmed by qRT-PCR. (B) The cell growth of GES cells at day 0, 1, 2, 3, 4 post transfection which was detected by CCK-8 assay. Data are shown as mean ± s.d. (n = 3); * indicates P-value <0.05;** indicates P-value <0.01. (C) The invaded GES cells in the Matrigel transwell invasion assay. Data are shown as mean + s.d. (n = 3); ** indicates P-value <0.01.
