Temporary Upregulation of Nrf2 by Naringenin Alleviates Oxidative Damage in the Retina and ARPE-19 Cells

Figure 5

The effect of NAR on Nrf2 activation after NaIO₃-induced damage in ARPE-19 cells. (a) Nuclear protein expression of Nrf2 after treatment for 1-24 h (Mauchly’s test of sphericity with Tukey’s test). (b) Representative fluorescence images of Nrf2 after 24 h treatment. (c) Protein expression of HO-1 after 6 h and 24 h treatment (Tukey’s test). (d) Viability of cells cotreated with NAR and/or ZnPP (Tukey’s test). Data were expressed as the , . and vs. normal group, ^# and ^## vs. model group, and ^A vs. NAR group.
