SOX4 knockdown suppresses migration, invasion and growth of invasive esophageal cancer cells. TE8 and FLO1 cells were transfected with non-targeting shRNA control or shSOX4. (A) SOX4 protein expression was analyzed by Western blotting. (B, C) miR-31 expression in response to SOX4 knockdown was measured by qRT-PCR, miR-191 and miR-423-5p were used as controls. miR-31, miR-191, miR-423-5p expression was normalized to RNU6. (D, E) Cell migration was measured using Boyden chamber transwell assays 24 hour post-transfection. (F, G) Invasion was measured by Marigel-coated transwell assays 24 hour post-transfection. (H, I) Cell viability was evaluated using the WST-1 assay. Results are means ± SD from at least three biological replicates.
