Levels of the mitochondrial biogenesis proteins (A) PGC-1α, (B) NRF1, and (C) mtTFA in the hippocampus of sham-operated (Sham) and ovariectomized (OVX) mice. Bars represent mean values ± standard error of the mean (SEM). *p < 0.05, **p < 0.01, ***p < 0.001 compared with the Sham mice at the same timepoint; &p < 0.05, &&p < 0.01 compared with the 2 weeks Sham mice; #p < 0.05, ###p < 0.001 compared with the 2-week OVX group (n = 4).
