a Representative confocal images of YAP/TAZ endogenous immunostaining in MCF10A cells expressing either wild-type or mutant (Y419A-V422A, L897A-F900A or Y419A-V422A-L897A-F900A) mEm-CTNNA1. Scale bars are 10 µm. The experiment was repeated three times with similar results. b YAP/TAZ localisation in MCF10A cells transfected with wild-type or mEm-CTNNA1 mutants. Bars represent the mean ± s.e.m. (n = 4 independent experiments; ***P < 0.001; two-way ANOVA). c YAP/TAZ localisation in MCF10A cells transfected with wild-type or mutants of mEm-CTNNA1 upon BafA1 exposure (200 nM, 16 h). Around 100 cells were analysed per condition —*P < 0.05, ns not significant; chi-squared test. d YAP/TAZ localisation in MCF10A cells transfected with wild-type or mutant forms of mEm-CTNNA1 upon α-catenin knockdown. Bars represent the mean ± s.d. (n = 3 independent experiments; ****P < 0.0001; two-way ANOVA). e TEAD luciferase activity in MCF10A cells expressing either wild-type or mutant (Y419A-V422A) Flag-CTNNA1. Bars represent the mean ± s.d. (n = 3 independent experiments; **P < 0.01, *P < 0.05; two-tailed one sample t-test). f Representative confocal images of BrdU-positive MCF10A cells transfected with wild-type or mutant forms of mEm-CTNNA1. Scale bars are 10 µm. The experiment was repeated three times with similar results. g Percentages of BrdU-positive cells in MCF10A cells transfected with wild-type or mutant forms of mEm-CTNNA1. Bars represent the mean ± s.e.m. (n = 4 independent experiments; ***P < 0.001, **P < 0.01, *P < 0.05; two-way ANOVA). h Size of MCF10A cells expressing either wild-type or the indicated mEm-CTNNA1 mutants. n = 25 cells per condition were analysed for measuring cell area using ZEN software. Bars represent the mean ± s.e.m (**P < 0.01, *P < 0.05; two-tailed t-test). Exact P values for asterisks: b 0.0003; e (from left to right) 0.0146, 0.0022, 0.0049; g (from left to right) 0.0043, 0.0207, 0.0019; h (from left to right) 0.0153, 0.0102, 0.0010.
