Figure 4. Quantification of 8-OHdG, 3-nitrotyrosine, and AGEs in the RPE of Atg5^ΔRPE and Atg7^ΔRPE mice. The immunofluorescence staining of 8-OHdG, 3-nitrotyrosine, and advanced glycation end products (AGEs) in the RPE was quantified using Image J software. n = 3 mice per genotype. Error bars indicate the mean ± standard deviation (SD). WT, wild-type control.
