Figure 3. Mitochondrial Mn-SOD activity is reduced in frail old.

Figure 3

(A) Mn-SOD protein content and (B) total- and Mn- SOD activity (U.mg of protein−1) in the vastus lateralis of young, AO, and SO subjects (N = 10/group; ♀  =  ♂). Asterisk denotes significant changes vs. young, and dagger denotes significant changes vs. AO (P≤0.05).
