Figure 8. Effects of paraquat on expression of antioxidant enzymes.

Figure 8

Undifferentiated (U) and differentiated (D) keratinocytes were treated with 100 µM paraquat or control. After 24 h, mRNA was extracted and analyzed for gene expression by real-time PCR (upper panel) or total cellular lysates were prepared and protein expression was analyzed by Western blotting (lower panel). Loading of equal amounts of protein was confirmed by silver staining of the gels. *p < 0.05, undifferentiated control cells versus paraquat-treated undifferentiated and differentiated cells. Each bar represents the mean ± SE (n = 3).
