Measurements have been made of the activity of ornithine decarboxylase of liver, heart,
kidney and brain in alloxan-diabetic and control rats. In all these tissues this enzyme had …

The activity of ornithine decarboxylase, the rate-controlling enzyme in polyamine
biosynthesis, was determined in tissues of normal control rats and rats made diabetic with …

1. Ornithine-2-oxo acid aminotransferase activity was inhibited by amino-oxyacetate (10 (-5)
M). This permitted the measurement of ornithine decarboxylase in the presence of …

Although the mean ornithine decarboxylase (ODC) activity induced by feeding in alloxan-
diabetic rats was 60% of that in normal rats, it was markedly suppressed in …

The regulation of ornithine decarboxylase activity was studied in freshly isolated rat
hepatocytes incubated in a chemically defined medium for 5 h. Glucagon, dibutyryl cyclic …

Abstract Ornithine decarboxylase (EC 4.1. 1.17) was purified to near homogeniety from
livers of thioacetamide-and dl-α-hydrazino-δ-aminovaleric acid-treated rats by using three …

Liver ornithine decarboxylase activity was found to undergo a remarkable diurnal change
with a peak at 20: 00 in rats receiving laboratory chow adlibitum. The enzyme was almost …

Ornithine decarboxylase [EC. 4.1. 1.17] was purified 3.5 X 10 (5)-fold with an overall yield of
8% from livers of rats treated with thioacetamide and DL-alpha-hydrazino-delta-aminovaleric …

Ornithine decarboxylase (Z,-ornithine carboxylase; EC 4.1. 1.17)(ODC) activity falls to
approximately 30% of the control value in diabetic rat kidney 4 weeks after induction of …

Several species of ornithine decarboxylase were separated by chromatography of rat
thymus and kidney extracts on DEAE-Sepharose CL-6B. One major and one minor species …
