Figure 8. Protein levels of superoxide dismutase 2 (SOD2) in gastrocnemius mitochondria isolated from adult (A, AX) and old (O, OX) rats treated or untreated with XJB.

Bottom panels show representative immunoblots (two per each group) with SOD2 and adenine nucleotide translocase (ANT) antibodies. Data were normalized to ANT (a mitochondrial housekeeping protein) and expressed as a fold change compared to the adult XJB-untreated (A) group. *P < 0.05 O and OX vs. A and AX.
