1 In addition, treatment with L-3,4-dihydroxyphenylalanine (L-DOPA) at 20-50 microM increased the intracellular dopamine content in PC12 cells and the increase of dopamine level by L-DOPA was significantly inhibited after exposure to TBTC at 0.5-2.0 microM for 24 h. These results indicate that TBTC decreases dopamine content by the inhibition of TH activity and TH mRNA level in PC12 cells. Levodopa tyrosine hydroxylase Rattus norvegicus
