Figure 2. Characteristic of PPARα^−/− mic. Representative H&E staining shows corneal morphology of PPARα^−/− mice and WT mice (A). Gene expression level of PPARα significantly decreased in PPARα^−/− mice (B). Gene expression level of PPARβ significantly increased in PPARα^−/− mice (C). Data are shown as mean ± SD n=6–8, **p<0.01, ***p<0.001. Scale bars: 100 μm.
