The PASI scores showed that the erythema of the K14-WFDC12 transgenic mice changed more significantly on Days 2–5 than that of WT mice (Figure 2B), and the scales and epidermal thickening of transgenic mice were more statistically evident on Days 3–5 than those of WT mice (Figures 2C, D). This evidence concerns the gene WFDC12 and Erythema.
