Nicotine 42-50 tyrosine hydroxylase Rattus norvegicus 13-33 19476543-1 2009 Repeated nicotine administration induces tyrosine hydroxylase (TH) mRNA in rat midbrain. Nicotine 9-17 tyrosine hydroxylase Rattus norvegicus 41-61 19476543-1 2009 Repeated nicotine administration induces tyrosine hydroxylase (TH) mRNA in rat midbrain. Nicotine 9-17 tyrosine hydroxylase Rattus norvegicus 63-65 19476543-3 2009 In both models nicotine stimulates TH gene transcription rate in a dose-dependent manner. Nicotine 15-23 tyrosine hydroxylase Rattus norvegicus 35-37 19476543-5 2009 Nicotine elevates circulating glucocorticoids, which induce TH expression in some model systems. Nicotine 0-8 tyrosine hydroxylase Rattus norvegicus 60-62 19476543-6 2009 We tested the hypothesis that the effect of nicotine on midbrain TH mRNA is mediated by the glucocorticoid receptor. Nicotine 44-52 tyrosine hydroxylase Rattus norvegicus 65-67 19476543-7 2009 When rats are administered the glucocorticoid receptor antagonist mifepristone, the induction of TH mRNA by nicotine in both substantia nigra and ventral tegmentum is inhibited. Nicotine 108-116 tyrosine hydroxylase Rattus norvegicus 97-99 19476543-9 2009 Our results are consistent with the hypothesis that nicotine induces TH mRNA in midbrain by elevating glucocorticoids, which then act on glucocorticoid receptors in dopamine neurons leading to transcriptional activation of the TH gene. Nicotine 52-60 tyrosine hydroxylase Rattus norvegicus 69-71 19476543-9 2009 Our results are consistent with the hypothesis that nicotine induces TH mRNA in midbrain by elevating glucocorticoids, which then act on glucocorticoid receptors in dopamine neurons leading to transcriptional activation of the TH gene. Nicotine 52-60 tyrosine hydroxylase Rattus norvegicus 227-229
