A and B: representative Western blot of nuclear factor erythroid 2-related factor 2 (Nrf2) in Z310 cells after 1 h treatment with vehicle, 10 μM SF, or 10 μM AITC and quantification (fold changes) of the Western blots. Values are means ± SE, n = 3. *Significant difference from vehicle-treated control at the P < 0.05 level. C and D: representative Western blot of whole cell lysate heme oxygenase-1 (HO-1) in Z310 and primary CP cells after 24 h treatment with vehicle, 10 μM SF, or 10 μM AITC and quantification (fold changes) of the Western blots. Values are means ± SE, n = 3–6. * and **Significant differences from vehicle-treated control at the P < 0.05 and P < 0.01 level, respectively.
