Figure 9. p38α mRNA levels in the retinal arteries and the neuroretina. p38α mRNA expression levels assessed with real-time PCR in eyes subjected to ischemia and 5 (n=11), 12 (n=8), or 20 (n=6) h of reperfusion (I-R) versus sham-operated eyes. Note that there was no difference in p38α expression between sham-operated and ischemia-reperfusion 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.
