(A) Representative Western blot analysis of transferrin, catalase, SOD1, SOD2, SOD3, GPx1, GPx2, TTR, NF-κB, IL-1β and RANKL in different groups. GAPDH was used as internal control. (B) Densitometric quantification of Western blot analysis for all tested proteins normalized to GAPDH (n = 3 for each group). *, P < 0.05, for results compared to those of the sham group; #, P < 0.05, for results compared to those of the group receiving an artificial knee joint only.
