Vesicular monoamine transporter 2 (VMAT2) expression in PC12 cells treated with (A) PCB95 or (B) PCB153. PCB95 significantly downregulated expression of VMAT2 after 12 h but not 24 h exposure. PCB153 did not have any effect on VMAT2 expression. *p<0.05 compared to the control; data are from 2 to 4 independent experiments.
