TRAF3IP1 mutations lead to epithelialization and polarity defects.(a) mIMCD3 cells grown until confluence on filters were subjected to Ca2+-free medium to disrupt the tight junctions. Six hours after Ca2+ addition, cells were analysed by immunofluorescence using the apical marker Gp135 (red) and beta-catenin (light blue) to stain the cell junctions. Scale bar, 10 μm. (b) Following Ca2+ switch, tight junction re-formation was assessed by measurement of trans-epithelial resistance (TER) at different time points (mean ± s.e.m. of n=5 independent experiments, two-way ANOVA; NS: not-significant, ***P<0.001 at 6 h). (c) Height of mIMCD3 cells grown on filters measured as the distance from the base to the top of the cells (GFP staining, not shown; mean ± s.d. of n≥20, from 3 independent experiments, ***P<0.001, Bonferonni's multiple-comparison test).
