Distribution of Wnt pathway array gene expression among treatment groups. (A) Fold change in gene expression relative to housekeeping genes (Actb, B2m, Gapdh, Gusb, and Hsp90ab1). (B) Relative changes in gene expression (upregulated or downregulated) in groups relative to WT PF. Open square: upregulated; closed circle: downregulated. Distributions of relative gene expression not statistically significant (P > 0.05; χ2); n = 3 from each group.
