Figure 11. Phosphorylated c-junNH₂-terminal kinase (JNK) protein content in the retinal arteries and neuroretina. Data are presented as mean optical density (A and B) and representative western blots (C and D) from animals subjected to ischemia and 5 (n=4), 12 (n=6), or 20 (n=5) h of reperfusion (I-R) and their corresponding sham-operated eyes. Values are presented as means±standard error of the mean. Statistical comparison was performed using a paired Student ratio t test (ischemia versus sham-operated eyes) with Bonferroni correction.
