Age‐dependent decreases in the levels of ornithine decarboxylase activity were observed in
the optic lobes, cerebral hemispheres, and midbrain‐diencephalon of 6–17‐day‐old chick …

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 …

Dibutyryl cyclic AMP (dibu-cAMP), N1-acetylputrescine and both N1-acetylspermidine and
N8-acetylspermidine regularly induce ornithine decarboxylase activity in both a time-and a …

1. The effect of a single administration of catecholamines on ornithine decarboxylase activity
and polyamine biosynthesis in the rat spleen was investigated. 2. Isoproterenol elicited a …

Ornithine decarboxylase (ODC) occurs in liver and kidney of control and hormone-treated
rats as two ionic forms, A and B in order of elution, separable by ion-exchange …

The developmental alteration in the specific activity of ornithine decarbox lase (ODC) was
investigated in the brain of rats treated with 6-hydroxydopa (6—OI—IDOP) at birth. The …

Isoprenaline stimulated increases in ornithine decarboxylase activity and polyamine content
in cardiac tissues are implicated in macromolecular synthesis and cellular growth, but little is …

Ornithine decarboxylase (ODC) activity is markedly stimulated in fetal rat primary hepatocyte
cultures by the addition of fresh growth medium and in hepatoma-derived cell cultures 2-6 hr …

Polyamines are thought to play an essential role in cellular hypertrophy and proliferation.
Ornithine decarboxylase (ODC) catalyzes the first and probably the rate-limiting step in …

The interaction between beta and alpha adrenergic agonists on regulation of cockerel aortic
ornithine decarboxylase (ODC) activity was examined. The beta adrenergic agonist …
