Barth, Angela I. M. Kim, Honesty H. Riedel-Kruse, Ingmar Rescue of epithelial sheet migration by expression of EpCAM-YFP or point mutants of EpCAM-YFP in MDCK cells depleted of EpCAM. <p><b>(A)</b> Phospho-ERK levels in EpCAM-depleted Esh2 cells (Esh) and Esh2-derived cell lines were analyzed as in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0204957#pone.0204957.g005" target="_blank">Fig 5A and 5B</a>. Error bars: S.E.M. of six independent samples for each cell line; <i>p</i> values derived from unpaired Student’s <i>t</i> test: *** <i>p</i> = 0.0004 for Esh+EY to Esh and *** <i>p</i> = 0.0001 for Esh+EEY to Esh. Phospho-ERK levels in Esh+EIY were not significantly reduced from the levels in the parental Esh line. <b>(B)</b> Phase images of indicated cell lines at 0 hrs (top row), and 6 hrs migration (middle row). The bottom row shows an overlay of “6 hrs” images onto “0 hrs” images. Scale bars: 100 μm. The graph in (B) shows quantification of average change of area/image after 6 hrs migration. Error bars: S.E.M. for five (Esh+EIY) to six experiments (Esh+EY, Esh+EEY) as shown in the phase images. Esh+EY and Esh+EEY migrate significantly slower than parental Esh cell sheets. The migration of Esh+EIY is not significantly different from Esh cell sheets. Stars correspond to <i>p</i> values derived from unpaired Student’s <i>t</i> test: * <i>p =</i> 0.0175 for Esh+EY and **<i>p</i> = 0.0063 Esh+EEY compared to Esh.</p> epithelial migration;ERK;Claudin -7 interaction;MDCK;epithelial cells;extracellular signal-regulated kinase;EpCAM;epithelial cell adhesion molecule;epithelial sheet migration;Claudin -7 interaction domain Epithelial cell adhesion molecule;myosin activation 2018-10-10
