Induction of Tyrosine Hydroxylase Protein and a Transgene Containing Tyrosine Hydroxylase 5′ Flanking Sequences by Stress in Mouse Adrenal Gland

Inhibitors of purified beef adrenal tyrosine hydroxylase.

Two classes of compounds have been investigated as inhibitors of purified beef adrenal tyrosine hydroxylase. Among the aromatic amino acids tyrosine analogues were found to be most potent, particularly those having an a-methyl or 3-halogen substitution. Two normal metabolites, monoand diiodo-tyrosine, were found to bevery effective inhibitors. Inhibition by the amino acid analogues was shown to...

Phenylalanine Hydroxylase, Tyrosine Hydroxylase, and Tryptophan Hydroxylase

In vitro phosphorylation of bovine adrenal tyrosine hydroxylase by adenosine 3':5'-monophosphate-dependent protein kinase.

We have studied the effects of adenosine 3':5'-monophosphate (cAMP)-dependent protein kinase on the phosphorylative and functional modification of bovine adrenal tyrosine hydroxylase. Incubation of partially purified tyrosine hydroxylase with cAMP-dependent protein kinase in the presence of [gamma32P]ATP and 5 micron cAMP led to a 3- to 5-fold activation of tyrosine hydroxylase and to incorpora...

Regulation of tyrosine hydroxylase activity by prostaglandin E1 in guinea pig adrenal gland.

The action of prostaglandin E1 on tyrosine hydroxylase activity in adrenal slices of guinea pig was studied. The activity of tyrosine hydroxylase and was decreased by the incubation of adrenal slices with prostaglandin E1 at concentrations beyond 2 mug per ml for 2 hours. The activity of tyrosine hydroxylase was stimulated by dibutyryl adenosine 3',5'-monophosphate in slices of guinea pig adren...

Adrenal and vascular tyrosine hydroxylase activity in Goldblatt hypertension.

To examine the role of the sympathetic nervous system in hypertension, the in vitro activity of tyrosine hydroxylase was examined in one-kidney, one clip (1K1C) and two-kidney, one clip (2K1C) hypertensive rabbits and their respective controls 2 weeks after surgical procedures. The in vitro activity of tyrosine hydroxylase provides a measure of catecholamine synthesis and serves as a biochemica...
