Previous studies from our own and other laboratories have shown that hypertension induces
changes in the growth of arterial smooth muscle cells (SMC). The purpose of this study was …

Myocardial phosphorylase alpha activity responds to stimulation by catecholamines and
thyroid hormone. In hyperthyroidism this enzyme is supersensitive to beta-adrenergic …

Ornithine decarboxylase (ODC, EC 4.1. 1.7), a rate-limiting enzyme in polyamine
biosynthesis, is known to be induced by a beta-adrenoceptor agonist, isoproterenol (ISO) …

Cardiac ODC was prepared from rats after the injection of isoproterenol and was partially
purified by thiol-affinity chromatography. This enzymatic preparation incubated with GSSG …

Ornithine decarboxylase (ODC) and its polyamine end-products have been suggested to
play important roles in outgrowth and function of central neurons. ODC displays high activity …

The relationship between isometric contraction and myocardial ornithine decarboxylase
(ODC; EC. 4.1. 1.17) activity was studied in right ventricular papillary muscles isolated from …

Quiescent baby hamster kidney ceils in 0.5% serum synthesize little DNA and have low
levels of ornithine decarboxylase(ODC), the rate-limiting enzyme in polyamine synthesis …

1. The perfusion for 15 min of isolated rat hearts with 100 microM t-butylhydroperoxide leads
to a 75% diminuition of the tissue GSH/GSSG ratio. 2. After t-butylhydroperoxide infusion, the …

Glucocorticoids regulate the coupling of beta-adrenergic receptors to cell function. In the
current study, the potential role of these agents in the development of adrenergic responses …

Publisher Summary This chapter discusses the method of induction of cardiac L-ornithine
decarboxylase by nicotinamide. In this method, male Sprague Dawley rats are fasted 20 h …
