Fig 1: Effects of rotenone and hMT2 on metallothioniein and bdnf gene expression. Bar graph presentation of the fold change of (A) mt2 and smtb, and (B) bdnf quantified by qPCR. All qPCR results are normalized to reference gene β-actin, and expressed as changes from the respective CTRL group. *p < 0.05, **p < 0.001 vs. CTRL; #p < 0.05, ##p < 0.001 vs. ROT (n = 6 per group).
