Ornithine decarboxylase in the small intestine of starved rats was stimulated 3-to 10-fold by
refeeding or administration of insulin. A peak is observed 3-5 h following treatment after …

Refeeding fasted rats with normal rat food and with a variety of amino acids increases
ornithine decarboxylase (ODC) activity considerably. The time course of that increase, the …

In rats, short-term starvation and subsequent refecding induced both holo-and total ornithine
decarboxylase (EC 4.1. 1.17) levels in colon 5-fold over ad lib fed controls. Starvation alone …

Rat liver ornithine decarboxylase activity was decreased by administration of putrescine (1,
4-diaminobutane) or other diamines, including 1, 3-diaminopropane, 1, 5-diaminopentane …

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 …

MATERIALS AND METHODS Materials-DL-[1-14C] Ornithine monohydro chloride (58
Ci/mmol) and [2-14C] glycine (54 Ci/mmol) were obtained from the Radio-Chemical Centre …

The hepatic ornithine decarboxylase (ODC) activity of normal rats was stimulated more than
7-fold 3 hours after a single intraperitoneal injection of dibutyryl cyclic adenosine 3′, 5 …

We compared the responses of rat stomach ornithine decarboxylase (ODC) and histidine
decarboxylase (HDC) to food intake, oral treatment with antisecretagogues, NaHCO3, and …

Re! peated injections of 1, 3-diaminopropane, a potent inhibitor of mammalian ornithine
decarboxylase, induced protein-synthesis-dependent formation of macromolecular inhibitors …

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 …
