Figure 3. Effect of 3-NPA injection for 7 days on antioxidant enzymes activities and mRNA levels in different organ tissues.
Mice were intraperitoneally injected with saline versus 3-NPA (12.5 mg/kg) for 7 days. (A) Antioxidant enzymes activities. (B) Relative expression levels of SOD2, GPX and CAT. Data show the means ± SEM (n = 5). * P<0.05, ** P<0.01 compared to control.
