Effects of aliphatic diamines on rat liver ornithine decarboxylase activity.
Rat liver ornithine decarboxylase activity was decreased by administration of putrescine (1,4-diaminobutane) or other diamines, including 1,3-diaminopropane, 1,5-diaminopentane and 1,6-diaminohexane. This effect was seen in control rats and in rats in which hepatic ornithine decarboxylase activity had been increased by administration of growth hormone (somatotropin) or thioacetamide. Loss of ac...
متن کاملMultiple Forms of Rat Liver Monoamine Oxidase
1. Treatment of a partly purified preparation of rat liver monoamine oxidase with the chaotropic agent sodium perchlorate caused the enzyme to migrate as a single band of activity on polyacrylamide-gel electrophoresis, whereas the untreated enzyme separated into a number of bands. 2. Treatment with the chaotropic agent caused no loss ofenzyme activity towards benzylamine, dopamine or tyramine. ...
متن کاملDifferent patterns of expression of ornithine decarboxylase mRNAs in rat liver after acute administration of hepatocarcinogens.
In the present study, we have evaluated the induction of ornithine decarboxylase (ODC) activity in rat liver after acute in vivo administration of different hepatocarcinogens, and correlated the ODC activity peaks with the accumulation of the three ODC-related mRNA species in rat liver at different times after the intraperitoneal injection of different hepatocarcinogens. ODC activity peaked 16 ...
متن کاملPurification and some properties of a protein inhibitor (antizyme) of ornithine decarboxylase from rat liver.
A protein inhibitor to ornithine decarboxylase, antizyme, was purified to homogeneity, as judged by sodium dodecyl sulfate-polyacrylamide gel electrophoresis, about 600,000-fold with a 15% yield from the liver cytosol of putrescine-treated rats. Antizyme was very labile but markedly stabilized in the presence of Tween 80 and 2-mercaptoethanol. The apparent molecular weight of antizyme was deter...
متن کاملEffect of 1,3-diaminopropane on ornithine decarboxylase enzyme protein in thioacetamide-treated rat liver.
A radioimmunoassay for ornithine decarboxylase was used to study the regulation of this enzyme in rat liver. The antiserum used reacts with ornithine decarboxylase from mouse, human or rat cells. Rat liver ornithine decarboxylase enzyme activity and enzyme protein (as determined by radioimmunoassay) were measured in thioacetamide-treated rats at various times after administration of 1,3-diamino...
