The influence of PDCD4 overexpression on cell migration and invasion. Siha cells infected with Lv-NC or Lv-PDCD4 were harvested to perform the migration assays (A, B) and the invasion assay (C, D). Cells migrated into the lower chamber (A) or invaded through the matrigel into the underside of the filter (C) were fixed, stained, and photographed at 200× magnification. The numbers of migrated (B) and invaded cells (D) were recorded. Data represent the average of three independent experiments. *P<0.05 compared with negative control.
