Polyamine Oxidase-Generated Reactive Oxygen Species in Plant Development and Adaptation: The Polyamine Oxidase—NADPH Oxidase Nexus [PDF]
Metabolism and regulation of cellular polyamine levels are crucial for living cells to maintain their homeostasis and function. Polyamine oxidases (PAOs) terminally catabolize polyamines or catalyse the back-conversion reactions when spermine is converted to spermidine and Spd to putrescine.

Exploring the activity of polyamine analogues on polyamine and spermine oxidase: methoctramine, a potent and selective inhibitor of polyamine oxidase [PDF]
Fourteen polyamine analogues, asymmetric or symmetric substituted spermine (1-9) or methoctramine (10-14) analogues, were evaluated as potential inhibitors or substrates of two enzymes of the polyamine catabolic pathway, spermine oxidase (SMOX) and acetylpolyamine oxidase (PAOX).

The tree of life of polyamine oxidases [PDF]
AbstractPolyamine oxidases (PAOs) are characterized by a broad variability in catalytic properties and subcellular localization, and impact key cellular processes in diverse organisms. In the present study, a comprehensive phylogenetic analysis was performed to understand the evolution of PAOs across the three domains of life and particularly within ...

Involvement of Polyamine Oxidase in Wound Healing [PDF]
AbstractHydrogen peroxide (H2O2) is involved in plant defense responses that follow mechanical damage, such as those that occur during herbivore or insect attacks, as well as pathogen attack. H2O2 accumulation is induced during wound healing processes as well as by treatment with the wound signal jasmonic acid.

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

Our paper systematically reviews the intestinal structure, function, and microbiota of ostriches, along with strategies for improving their gut health. We analyze how these factors collectively influence intestinal homeostasis and ostrich welfare, emphasizing probiotics as a promising intervention to enhance gut health, boost population well‐being, and

A Systematic Review on Disease‐Modifying Therapies in Parkinsonian Disorders
Parkinsonian disorders, including Parkinson's disease, Lewy body dementia, multiple system atrophy, and progressive supranuclear palsy, are progressive neurodegenerative conditions with no treatment options to slow disease progression. This systematic review provides an overview of evidence of disease‐modifying therapies that have been evaluated in ...

Thioredoxin system modulates metabolic and stomatal responses to elevated CO2 in Arabidopsis
Integrative model of extraplastidial NADPH‐dependent thioredoxin reductase/thioredoxin system‐mediated regulation of stomatal function, redox homeostasis, and metabolic responses under ambient and elevated CO2 in Arabidopsis thaliana. Summary The NADPH‐dependent thioredoxin reductase/thioredoxin (NTR/TRX) system plays a central role in maintaining ...

ABSTRACT Sugar crops, including but not limited to sugarcane, sugar beet, sweet sorghum and stevia, are major sources of sugar production in the world. However, conventional breeding approaches, limited by long breeding cycles, low efficiency and restricted capacity to improve complex traits in sugar crops, are increasingly insufficient to address the ...
