Intraperitoneal injection of chlorpromazine and imipramine increases mouse brain ornithine
decarboxylase but decreases S-adenosyl-l-methionine decarboxylase activity. Maximal …

The present study was examined whether tyramine-released norepinephrine enhances the
production of interstitial adenosine via stimulation of ecto-5′-nucleotidase (a key enzyme …

Ornithine decarboxylase is a rate-limiting step in the formation of the polyamines
(putrescine, spermidine, and spermine). Ornithine decarboxylase activity (ODC) is increased …

The effect of a single tube feeding of l-tryptophan on hepatic ornithine decarboxylase (ODC)
activity in rats was investigated. The levels of ODC activity in the livers of control and …

The β-adrenergic agonist 1-isoproterenol (0.1 μM) evokes an acute (< 5–10 sec) transient
increase in the activity of ornithine decarboxylase (ODC), and the levels of polyamines …

Inhibition of cardiac ornithine decarboxylase (ODC) by α-difluoromethylornithine (DFMO) did
not prevent normal cardiac growth in mature rats but attenuated isoproterenol-induced …

Administration of the dopamine receptor agonists apomorphine (APM) and piribedil
increases adrenocortical ornithine decarboxylase (ODC) activity. In this paper alterations in …

Monoamine oxidase (MAO) catalyzes the biological degradation of the neurotransmitters
monoamines. The altered substrate specificity of MAO may be of pathogenic importance in …

Ornithine decarboxylase, the rate-limiting enzyme in polyamine biosynthesis, may be
controlled by a cAMP-dependent mechanism. This hypothesis was investigated in the …

Numerous studies support the concept that centrally acting antihypertensive drugs, such as
imidazolines, mediate sympathoinhibition not only via activation of central nervous α2 …
