Mathematical Modeling of Polyamine Metabolism in Mammals [PDF]

Journal of Biological Chemistry, 2006
Polyamines are considered as essential compounds in living cells, since they are involved in cell proliferation, transcription, and translation processes. Furthermore, polyamine homeostasis is necessary to cell survival, and its deregulation is involved

Dissecting rice polyamine metabolism under controlled long-term drought stress.

PLoS ONE, 2013
A selection of 21 rice cultivars (Oryza sativa L. ssp. indica and japonica) was characterized under moderate long-term drought stress by comprehensive physiological analyses and determination of the contents of polyamines and selected metabolites ...

Antizyme Inhibitors in Polyamine Metabolism and Beyond: Physiopathological Implications

Medical Sciences, 2018
The intracellular levels of polyamines, cationic molecules involved in a myriad of cellular functions ranging from cellular growth, differentiation and apoptosis, is precisely regulated by antizymes and antizyme inhibitors via the modulation of the ...

Alterations of renal polyamine metabolism in mice with folic acid-induced chronic kidney disease [PDF]

Biochemistry and Biophysics Reports
Chronic kidney disease (CKD) often follows acute kidney injury, leading to renal fibrosis and progressive renal failure. Spermine, a polyamine with antioxidant and anti-inflammatory properties, helps reduce renal fibrosis and may serve as a biomarker for

Investigation of The Roles of Hydrogen Peroxide and NADPH Oxidase in The Regulation of Polyamine Metabolism in Maize Plants under Drought Stress Conditions

Journal of Agricultural Sciences, 2022
The relationship between hydrogen peroxide and the metabolism of polyamines and the role of NADPH oxidase (NOX) in that relationship under drought conditions remains unclear.

Polyamine metabolism and cancer [PDF]

Journal of Cellular and Molecular Medicine, 2003
AbstractPolyamines are aliphatic cations present in all cells. In normal cells, polyamine levels are intricately controlled by biosynthetic and catabolic enzymes. The biosynthetic enzymes are ornithine decarboxylase, S‐adenosylmethionine decarboxylase, spermidine synthase, and spermine synthase.

Light Spectral Composition Modifies Polyamine Metabolism in Young Wheat Plants [PDF]

, 2022
Although light-emitting diode (LED) technology has extended the research on targeted photomorphogenic, physiological, and biochemical responses in plants, there is not enough direct information about how light affects polyamine metabolism. In this study,

Polyamine Metabolism under Different Light Regimes in Wheat [PDF]

, 2021
Although the relationship between polyamines and photosynthesis has been investigated at several levels, the main aim of this experiment was to test light-intensity-dependent influence of polyamine metabolism with or without exogenous polyamines.

Stress and polyamine metabolism in fungi [PDF]

Frontiers in Chemistry, 2014
Fungi, as well as the rest of living organisms must deal with environmental challenges such as stressful stimuli. Fungi are excellent models to study the general mechanisms of the response to stress, because of their simple, but conserved, signal-transduction and metabolic pathways that are often equivalent to those present in other eukaryotic systems.

Polyamine Immunometabolism: Central Regulators of Inflammation, Cancer and Autoimmunity

Cells, 2022
Polyamines are ubiquitous, amine-rich molecules with diverse processes in biology. Recent work has highlighted that polyamines exert profound roles on the mammalian immune system, particularly inflammation and cancer. The mechanisms by which they control
