miR-4429 down-regulates the expression of Wnt/β-catenin. a protein level of β-catenin after miR-4429 administration determined by western blot analysis (one-way ANOVA, P < 0.0001) (see original western blots in Additional file 1: Figure S2); b protein level of β-catenin after pcDNA-DLX1 administration determined by western blot analysis (one-way ANOVA, P = 0.0009) (see original western blots in Additional file 1: Figure S3). Data were expressed as mean ± SD from three independent experiments. *P < 0.05 was considered to show statistical significance
