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

Ornithine decarboxylase (ODCase; L-ornithine carboxy-lyase; EC 4.1. 1.17) activity was
increased 5-20 fold above basal activity by N 6, O 2′-dibutyryl cyclic AMP, isoproterenol …

Polyamines are polycationic substances which are widely distributed in living organisms
and have a close relation to rapid growth phenomena. We examined ornithine …

Previous studies in vivo have shown that the activity of ornithine decarboxylase (ODC), the
rate-controlling enzyme in polyamine biosynthesis, is markedly decreased in muscle of …

The influence of acidosis on the inotropic effect of isoproterenol was studied in the isolated
arterially perfused heart of the newborn rabbits. Baseline mechanical function during …

In primary cultures of adult rat hepatocytes maintained in a salts/glucose medium, a more
than 100-fold increase in ornithine decarboxylase (EC 4.1. 1.17) activity was caused by …

Antiserum elicited to ornithine decarboxylase (ODC) purified from murine RAW 264
macrophage-like cells has been employed to localize ODC in cultured murine cells. The …

The onset of sympathetic innervation has been shown to play a role in the development of
postsynaptic reactivity to stimulation. In the current study, we examined whether this …

Abstract Partial hepatectomy (PH)(70% resection) causes within 4 hr an accumulation of
ornithine decarboxylase (EC 4.1. 1.17, ODC) mRNAs concomitant with an increase in ODC …

A single injection of thioacetamide into starved rats induced a 40-to 100-fold increase in
hepatic ODC activity. However, immunotitratable ODC protein increased by only 5-fold …
