Semicarbazide diminishes the signs of bleomycin-induced pulmonary fibrosis in rats [PDF]

open access: yesThe Ukrainian Biochemical Journal, 2021
The pathogenesis of pulmonary fibrosis (PF) is accompanied by extracellular matrix (ECM) deposition, oxidative stress, and inflammation progression, as well as hyperactivation of amine oxidases (AOs), which contribute to disease manifestation.

Modulation of polyamine catabolism in pea seedlings by calcium during salinity stress

open access: yesPlant Protection Science, 2012
The relation of polyamine catabolism in the response of Pisum sativum to salinity stress was investigated. Pea seedlings were grown in increasing concentrations of Na+ or K+ or at different concentration ratios of these ions. We studied the effect of Ca2+

Study of the Characterization of Partial Purified Polyamine Oxidase from Sheep's Brain Tissue [PDF]

open access: yesمجلة التربية والعلم, 2019
The study included partially purified of polyamine oxidase (PAO) from sheep's brain tissue by dialysis and ion exchange chromatography using DEAE-cellulose techniques. Tow isoenzymes (I،II) were obtained with specific activities 3.876 and 2.856 units/ mg

Polyamine oxidase activity contributes to sustain maize leaf elongation under saline stress [PDF]

open access: yes, 2009
The possible involvement of apoplastic reactive oxygen species produced by the oxidation of free polyamines in the leaf growth of salinized maize has been studied here. Salt treatment increased the apoplastic spermine and spermidine levels, mainly in the

Inhibition of Lymphocyte Proliferation by Polyamines Requires Ruminant-Plasma Polyamine Oxidase [PDF]

open access: yesEuropean Journal of Biochemistry, 1979
Spermine and spermidine in vitro are potent inhibitors of proliferation of phytohaemagglutinin-stimulated rat thymic lymphocytes, lymphoma cells and human lymphoblastic leukaemia cells, but only in media supplemented by foetal calf serum. This inhibition is shown to be due to a bovine plasma polyamine oxidase, with a high specificity for these ...

Effect of Exogenous γ-Aminobutyric Acid on the Quality and γ-Aminobutyric Acid Metabolism of Fresh-cut Pumpkins

open access: yesShipin gongye ke-ji, 2022
The effect of exogenous γ-aminobutyric acid (GABA) and GABA synthesis inhibitor 3-mercaptopropionic acid (3-MP) on GABA metabolism and quality in fresh-cut pumpkin was investigated, and the possible mechanism was studied.

Correlation of polyamines, acrolein-conjugated lysine and polyamine metabolic enzyme levels with age in human liver

open access: yesHeliyon, 2020
The polyamines spermidine, spermine and putrescine are essential for normal cellular functions. The contents of polyamines in tissue decreased in aged mice compared to young mice.

Characterisation of the flavin adenine dinucleotide binding region in Myxococcus xanthus protoporphyrinogen oxidase [PDF]

open access: yes, 2011
This dissertation focuses on protoporphyrinogen oxidase (PPOX), the penultimate enzyme in the haem biosynthetic pathway. Partial defects in PPOX result in variegate porphyria, an autosomal dominant disorder.
