Testosterone ameliorates age-related brain mitochondrial dysfunction


Figure 3. TP supplementation increases the expression of TH and DAT in the SN of aged male rats. (A) Representative western blots of TH and DAT expression. (B, C) Quantification of TH and DAT protein levels (normalized to β-actin; n = 5/group). (DG) Representative IHC photomicrographs of TH and DAT expression in the SN of experimental rats (n = 6/group). Scale bars = 200 μm. Data are expressed as the mean ± S.D. *P < 0.05, **P < 0.01 (Bonferroni test).
