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

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

The β-adrenergic agonist 1-isoproterenol induced an early (< 1 min) stimulation of
endocytosis, amino acid transport and hexose transport, monitored by the temperature …

The objective of this study was to examine the effect of indapamide on cAMP generation in
cardiomyocytes. Viable ventricular myocytes were isolated from adult rat hearts which …

Abstract Sprague Dawley male rats (200–220 g) were subjected to a long-term treatment
with low doses of catecholamines in an attempt to assess the effect of the adrenergic …

Studies of stress-induced cardiac hypertrophy suggest that myocardial mass is regulated by
the circulating level of epinephrine. The trophic effect is mediated by cardiac beta …

Apoptotic cell death of cardiomyocytes is involved in several cardiovascular diseases
including ischemia, hypertrophy, and heart failure. The polyamines putrescine, spermidine …

In the isolated cardiomyocytes of spontaneously hypertensive rats (SHR, 3 months old) MAO
A and B activities were significantly increased compared to the myocytes in the hearts of age …

AUTHORS'SYNOPSIS In cell-free systems putrescine, spermine, and spermidine at
concentrations of 15 to 100 μg had no significant effect at 11 mM Mg2+ on rat myocardial …

The polyamines putrescine, spermidine and spermine play essential roles in cell
proliferation and migration, two processes involved in the development of vascular disease …
