LRE mitigated oxidative stress in the retina of the laser-induced COH and the DBA/2J mice. (A) Representative images of 8-OHdG stained retinal sections from normal, water-fed, and LRE-fed COH mice. Scale bar, 25 µm. (B) LRE significantly reduced the fluorescence intensity of 8-OHdG in the retina of the COH eyes. (C) The gene expressions of HO-1, SOD-2, and GPX-4 in the retina of the normal, water-fed, and LRE-fed COH eyes. (D) Representative images of 8-OHdG stained retinal sections from the C57BL/6J control, water-fed, and LRE-fed DBA/2J mice. Scale bar, 25 µm. (E) LRE significantly reduced the fluorescence intensity of 8-OHdG in the retina of the DBA/2J mice. *, p < 0.05; **, p < 0.01; ***, p < 0.001.
