The treatment of emodin inactivated the Wnt/β-catenin signaling pathway. Cells in each group were treated as previously described. (A) The expression of TCF4, cyclin D1, and c-Myc was measured by Western blot. (B–D) Quantification of (A). All the experiments were repeated at least three times. GAPDH was used as an internal reference. *p < 0.05, **p < 0.01, ***p < 0.001 versus the control group.
