Fig. 2. Effects of sericin and I-sericin or fibroin and I-fibroin on antioxidant enzymes in H2O2 treated HaCaT cells.

Fig. 2

(A) ROS production of HaCaT cell with (A1) sericin or I-sericin and (A2) fibroin or I-fibroin pretreatment followed by H2O2; (B) SOD activity of HaCaT cell with (B1) sericin or I-sericin and (B2) fibroin or I-fibroin pretreatment followed by H2O2; (C) GSH content of HaCaT cell with (C1) sericin or I-sericin and (C2) fibroin or I-fibroin pretreatment followed by H2O2. ROS, reactive oxygen species; SOD, superoxide dismutase; GSH, glutathione. Different label means a significant difference between each group by one-way ANOVA. **p < 0.01, compared to control. ***p < 0.001, compared to control. #p < 0.05, ##p < 0.01 compared with H2O2-treated only. $p < 0.05, compared to the sericin or fibroin-treated group.
