TIPE1 and gastric cancer: By wound‐healing assay, we found that overexpression of TIPE1 in BGC823 and SGC7901 cells had significantly slower closure of the wound area compared to their controls (Fig. 3A–B), which was further confirmed by transwell (Fig. 3C) and matrigel invasion assays (Fig. 3D) indicating that TIPE1 regulated migratory and invasive behaviours of gastric cancer cells.
