Thus, we also examined the SOD2 expression levels and found that the levels of SOD2 proteins were decreased in the infarcted right ischemic cortex regions after 60 min of ischemia, suggesting that the increase in ROS and infarcted areas observed in the right ischemic cortex regions were highly correlated with the reduced level of SOD2 (Figure 3). Here, SOD2 is linked to ischemia.
