Figure 8: Western blot analysis for nuclear factor E2related factor 2 and heme oxygenase1. (a) Nuclear factor E2related factor 2, heme oxygenase1 and βactin expression where 1  control, 2  flavonoidenriched fraction control, 3  ultravioletB control, 4  positive control, 5  ultravioletB irradiated fibroblasts + 10 μg/ml fraction, 6  ultravioletB irradiated fibroblasts + 20 μg/ml fraction, and 7  ultravioletB irradiated fibroblasts + 40 μg/ml fraction; (b) Densitometric analysis of nuclear factor E2related factor 2 bands; (c) Densitometric analysis of haem oxygenase1 bands; and (d) Densitometric analysis of βactin bands. Results were statistically analyzed using GraphPad Prism software by oneway analysis of variance followed by Dunnett's posttest and unpaired ttest to compare inbetween the groups, +P < 0.05, ^{**}P < 0.01, ^{***}P < 0.001
