1 Chronic nicotine treatment leads to sustained stimulation of tyrosine hydroxylase gene transcription rate in rat adrenal medulla. Nicotine tyrosine hydroxylase Rattus norvegicus
2 In previous reports, we have studied the mechanisms by which short-term nicotine treatment regulates tyrosine hydroxylase (TH) in adrenal medulla. Nicotine tyrosine hydroxylase Rattus norvegicus
3 In previous reports, we have studied the mechanisms by which short-term nicotine treatment regulates tyrosine hydroxylase (TH) in adrenal medulla. Nicotine tyrosine hydroxylase Rattus norvegicus
4 In this report, we study the effects of chronic nicotine treatment on adrenal TH gene expression. Nicotine tyrosine hydroxylase Rattus norvegicus
5 Chronic nicotine treatment elicited long-lasting, dose-dependent increases in the levels of adrenal TH mRNA, TH protein, and TH activity. Nicotine tyrosine hydroxylase Rattus norvegicus
6 Chronic nicotine treatment elicited long-lasting, dose-dependent increases in the levels of adrenal TH mRNA, TH protein, and TH activity. Nicotine tyrosine hydroxylase Rattus norvegicus
7 Chronic nicotine treatment elicited long-lasting, dose-dependent increases in the levels of adrenal TH mRNA, TH protein, and TH activity. Nicotine tyrosine hydroxylase Rattus norvegicus
8 In contrast, a single injection of nicotine elicited only a small increase in adrenal TH mRNA levels, which was transient and did not result in the induction of TH enzyme. Nicotine tyrosine hydroxylase Rattus norvegicus
9 These results demonstrate that repeated nicotine injections administered chronically over 1 to 2 weeks lead to sustained stimulation of the TH gene and consequent induction of TH gene expression in rat adrenal medulla. Nicotine tyrosine hydroxylase Rattus norvegicus
