Fig 9. Protein expression of anti-oxidative enzymes in the UV-Filtering (UVF), Selective Blue-Filtering (S-BF) and no lens groups under blue LED irradiation.

(A) Representative western blot of the anti-oxidative enzymes catalase and Prdx3. GAPDH was used as a loading control. (B) Quantification analysis of protein levels of catalase and Prdx3. Under blue light irradiation, S-BF lens showed higher expression of catalase than no lens (p = 0.035) and UVF lens (p = 0.020). UVF lens also showed a higher level of catalase compared to no lens (p = 0.040). The S-BF lens showed a higher expression level of Prdx3 than no lens (p = 0.026) and UVF lens (p = 0.028). A.U.: arbitrary unit. (n = 3, one way ANOVA, * p < 0.05) The values are expressed as Mean ± SEM.
