Post-transcriptional regulation of ornithine decarboxylase in Xenopus laevis oocytes. [PDF]

, 1990
International audienceThe level at which ornithine decarboxylase expression is regulated in growing oocytes has been investigated. Immunoprecipitation of the in vivo labelled proteins showed that ornithine decarboxylase accumulated less rapidly in stage ...

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

, 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 ...

Effect of oxygen radicals and hyperoxia on rat heart ornithine decarboxylase activity [PDF]

, 1982
Rat heart ornithine decarboxylase activity from isoproterenol-treated rats was inactivated in vitro by reactive species of oxygen generated by the reaction xanthine/xanthine oxidase.

Revisiting small‐molecule fluorescent probes in food freshness detection

Smart Molecules, EarlyView.
Fluorescent probes serve as versatile tools for food freshness monitoring. This review summarizes recent advances in probes targeting biogenic amines, hydrogen sulfide, pH values, and other key spoilage markers, highlighting their design principles, sensing mechanisms, and practical applications in food quality monitoring. Abstract Food spoilage driven

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

, 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 ODC 3′-Untranslated Region and 5′-Untranslated Region Contain cis-Regulatory Elements: Implications for Carcinogenesis

Medical Sciences, 2017
It has been hypothesized that both the 3′-untranslated region (3′UTR) and the 5′-untranslated region (5′UTR) of the ornithine decarboxylase (ODC) mRNA influence the expression of the ODC protein.

Inhibition of Ornithine Decarboxylase 1 Mitigates Denervation‐Induced Muscle Atrophy by Suppressing Proteolysis and Preserving Muscle Stem Cell Homeostasis

Cell Proliferation, EarlyView.
Polyamine metabolism is innervation responsive and involved in denervation‐induced muscle atrophy. Inhibition of polyamine metabolism attenuates muscle atrophy by restraining proteolysis and preserving MuSCs homeostasis. Denervation‐induced activation of FAP‐derived FGF7 drives premature MuSCs activation, while DFMO suppresses this paracrine cue to ...

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

, 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.

Malaria mosquito antimicrobial defence requires immunity and detoxification gene regulation by Lola

Insect Molecular Biology, EarlyView.
Malaria mosquito antimicrobial defence requires upregulation of lola. Attenuation of lola in the midgut of Anopheles albimanus mosquitoes inhibits the upregulation of immunity genes induced by challenge. Putative target genes of the Lola transcription factor were revealed by lola attenuation, including Cecropin‐C, Draper, PPAF2, Clip‐domain serine ...

Differential effects of difluoromethylornithine on basal and induced activity of cerebral ornithine decarboxylase and mRNA [PDF]

, 1991
The induction of the activity of cerebral ornithine decarboxylase (EC 4.1.1.17) and mRNA by electrical stimulation exhibits regional differences. The effects of the enzyme inhibitor difluoromethylornithine on these regional variations was examined ...
