Diverse Functions of Polyamines in Virus Infection
Biomolecules, 2020 As obligate intracellular parasites, viruses rely on host cells for the building blocks of progeny viruses. Metabolites such as amino acids, nucleotides, and lipids are central to viral proteins, genomes, and envelopes, and the availability of these ...

Dual Functions of Polyamines in Shaping Host-Specific Pathogen Dynamics. [PDF]
PathogensPolyamines such as putrescine, spermidine, and spermine play essential roles in most living organisms. They regulate fundamental processes, like cell proliferation, differentiation, growth, gene expression (DNA/RNA stability, transcription, and ...

Cation Homeostasis: Coordinate Regulation of Polyamine and Magnesium Levels in Salmonella
mBio, 2023 Polyamines are organic cations that are important in all domains of life. Here, we show that in Salmonella, polyamine levels and Mg2+ levels are coordinately regulated and that this regulation is critical for viability under both low and high ...

Polyamines and adventitious root formation in Vitis vinifera L.
OENO One, 2002 The effects of polyamines were examined for growth and polyamine contents in cultings, callus and primary adventitious roots of Vitis vinifera L. Variations in free, conjugated and wall-bound polyamines in cuttings were observed during rhizogenesis.

Polyamines and apoptosis [PDF]
Journal of Cellular and Molecular Medicine, 2005 The natural polyamines putrescine, spermidine and spermine are in multiple ways involved in cell growth and the maintenance of cell viability. In the course of the last 15 years more and more evidence hinted also at roles in gene regulation. It is therefore not surprising that the polyamines are involved in events inherent to genetically programmed ...
