The activity of ornithine decarboxylase (ODC), the rate-limiting enzyme involved in the
biosynthesis of polyamines, is markedly elevated in the adult rat heart 4 hr after …

Adult male rats were injected either with α-or ß-adrenergic agonists and/or antagonists and
ornithine decarboxylase (ODC) activity in the heart and aorta was measured 4 hours later. At …

Ornithine decarboxylase activity in rat heart was increased significantly by the injection of l-
norepinephrine or nisoxetine, an inhibitor of norepinephrine uptake. The enzyme was also …

An acute treatment of mice with clenbuterol, a β-adrenergic agonist, produced a marked
increase of polyamines levels in heart, particularly during the early phase of administration …

Ornithine decarboxylase (ODC), the rate-limiting enzyme in the biosynthesis of polyamines,
displays high activity early in postnatal development of the heart, followed by a gradual …

Stimulation of ornithine decarboxylase (ODC) activity was examined in cultured heart cells
from neonatal rats. Fetal bovine serum had a concentration-dependent effect on ODC …

Objective: TGF-β stimulation of cardiac myocytes induces a hypertrophic responsiveness to
β-adrenoceptor stimulation. This study investigates whether this β-adrenoceptor mediated …

Ornithine decarboxylase(ODC) is a marker of tissue growth and development and, because
sympathetic stimulation of beta adrenergic receptors acutely increases ODC in the adult rat …

Heart ornithine decarboxylase (ODC) from isoproterenol treated rats was compared to heart
ODC from control rats. Isoproterenol administration did not significantly change Km for …

Sympathetic stimulation elevates heart ornithine decarboxylase (ODC) activity in adult rats,
an effect which is followed by cardiac hypertrophy. In developing animals, adrenergic …
