Figure 4: Differential expression of WNT7B between treated eyes and fellow eyes in experimental myopia mice (n=5 in each arm).

The vertical axis indicates WNT7B expression normalized to β-actin expression. WNT7B expression in the retina was significantly upregulated in the experimental myopia eyes (P=0.016 by Wilcoxon test), but was significantly downregulated in the cornea (P=0.028 by Wilcoxon test).
