The cell migration ability in tumor cell lines, which determined by Wound Healing assay, was inhibited after the treatment of 5-Aza-dC or overexpression of HOXD10 from Fig. 7a, left, which captured at 0 and 48 h after the wound was made, and corresponding histograms showed the same trend (Fig. 7a, right). This evidence concerns the gene HOXD10 and neoplasm.
