Melatonin Increases Bone Mass around the Prostheses of OVX Rats by Ameliorating Mitochondrial Oxidative Stress via the SIRT3/SOD2 Signaling Pathway

Figure 5

Activation of the SIRT3/SOD2 signaling pathway was essential to the antioxidative effects of melatonin. (a, b) The efficiency of SIRT3 siRNA was confirmed by Western blot ( per group, ^&& vs. the scramble SiRNA group). (c–h) Western blot of SIRT3, Ac-SOD2, SOD2, cyto-c, NOQ1, and Nrf2 ( per group, and vs. the H₂O₂ group, ^# and ^## vs. the H₂O₂ + MT group).
