Fig. 3. Analysis of protein carbonyl content and antioxidant enzyme expression in testes of mutant mice.

Fig. 3

A. Protein carbonyl content is increased in 13-month-old mutant mice. Mean ± SEM of 5 mice for each group are presented. *** indicates p<0.001 by two-way ANOVA and Bonferroni post-tests. (B, C). Expression of antioxidant enzymes SOD1, SOD2, and catalase in testes of 2-~5-month-old mice (B) and 13-month-old mice (C). Mean ± SEM (n=5 for each group) of integrated density analyzed by Image J software are presented. Loading was normalized by β-actin. * indicates p<0.05 by t-tests. D. Catalase protein was increased in 13-month-old mice than in 2-~5-month-old mice.
