Fig. 4From: DKK1 inhibits breast cancer cell migration and invasion through suppression of β-catenin/MMP7 signaling pathwayOverexpression of DKK1 inhibited β-catenin protein expression in MCF-7 (a) and MDA-MB-231 (b) cells. β-actin was used as an internal reference of total protein, results are presented as mean ± SEM, *p < 0.05, **p < 0.01, ***p < 0.001 compared to the empty vector group, #p < 0.05, ##p < 0.01, ###p < 0.001 compared to the naive group, n = 5 per group, one-way ANOVA.
