Stabilization of ornithine decarboxylase in erythroleukemia cells depleted of ATP

open access: yes, 1989
Ornithine decarboxylase activity in Friend erythroleukemia cells decayed with a half-life of 50 minutes after addition of cycloheximide and at a faster rate after addition of spermidine.

Baicalein, 7,8-Dihydroxyflavone and Myricetin as Potent Inhibitors of Human Ornithine Decarboxylase

open access: yes, 2022
Background: Human ornithine decarboxylase (ODC) is a well-known oncogene, and the discovery of ODC enzyme inhibitors is a beneficial strategy for cancer therapy and prevention.

Regulation of ornithine decarboxylase from Mycobacterium smegmatis

open access: yes, 1988
The activity of ornithine decarboxylase in Mycobacterium smegmatis is regulated by a novel macromolecular inhibitor-a ribonucleic acid. Addition of polyamines to the growth medium enhances the level of this inhibitor, suggesting that the level of this ...

PURIFICATION AND CHARACTERIZATION OF BOVINE LIVER ORNITHINE DECARBOXYLASE

open access: yes, 1980
Ornithine decarboxylase has been purified to apparent homogeneity from thioacetamide-stimulated calf liver. The purification process, which has been developed to circumvent the lability of the enzyme, employs ion exchange chromatography, gel filtration ...

Permanent decrease in activity of ornithine decarboxylase antizyme in rat liver during chemical hepatocarcinogenesis

open access: yes, 1983
This study was undertaken to determine whether or not there is failure of cellular control of L-ornithine decarboxylase activity by its antizyme, the only known natural intracellular inhibitor protein for L-ornithine decarboxylase activity, in rat liver ...

Ornithine decarboxylase protein was present in the urogenital epithelium in the developing urogenital sinus.

open access: yes, 2015
In the male UGS before budding at E15 (A) and E16 (B), ornithine decarboxylase protein (green) was present in the epithelium. As the buds emerged from the epithelium at E17 (E) and E18 (G), ornithine decarboxylase protein was still expressed in the ...

The Subcellular Distribution of Uterine Ornithine Decarboxylase Following Estrogen Treatment [PDF]

open access: yes, 1985
Within a cell, the basic structure and functional unit of all living things, many substances contribute to its continuing existence. Ornithine decarboxylase, an enzyme, is one of these substances.

Restoration of normal ornithine decarboxylase antizyme activity in rat liver after acute carcinogen treatment

open access: yes, 1983
This study was undertaken to see whether or not the decrease in ornithine decarboxylase antizyme activity caused in rat liver by a hepatocarcinogen could be reversed. Thioacetamide was administered only once, in a single i.p.

Potentiation by Retinoic Acid of Ornithine Decarboxylase Induction by Phytohemagglutinin or Phorbol 12-Myristate 13-Acetate in Guinea Pig Lymphocytes

open access: yes, 1986
Retinoic acid potentiated the increases in ornithine decarboxylase (L-ornithine carboxy-lyase [EC 4.1.1.17]) activity, [3H]difluoromethylornithine binding to ornithine decarboxylase, intracellular levels of polyamines and DNA synthesis in guinea pig ...
