MIER3 overexpression suppresses migration and invasion of NSCLC cells. A549 and H460 cells were transfected with pcDNA3.1-vector or pcDNA3.1-MIER3 for 24 h. (A) Cell migration was detected by wound healing assay. (B) The migration distance was quantified by Image J software, and the wound closure rate was presented. (C) Cell invasion was measured by Matrigel Transwell assay, images were magnified at ×200. (D) Invasion cells per field was presented. *, P<0.05 versus vector control. MIER3, mesoderm induction early response 1, family member 3; NSCLC, non-small cell lung cancer.
