Polyamines as redox homeostasis regulators during salt stress in plants

open access: yesFrontiers in Environmental Science, 2015
The balance between accumulation of stress-induced polyamines and reactive oxygen species (ROS) is arguably a critical factor in plant tolerance to salt stress.

Polyamines in Soybeans [PDF]

open access: yesPlant Physiology, 1972
Putrescine, spermidine, and spermine were three main polyamines isolated from soybeans and partially characterized. Occurrence of polyamines in soybeans was established by separating trichloroacetic acid extracts of soybeans by cationic exchange column chromatography, identification with thin layer chromatography, paper electrophoresis, mass spectral ...

Polyamines in Halophytes [PDF]

open access: yesFrontiers in Plant Science, 2019
Polyamines (PAs) are related to many aspects of the plant's life cycle, including responses to biotic and abiotic stress. On the other hand, halophytic plants are useful models for studying salt tolerance mechanisms related to the adaptive strategies that these plants present in adverse environments.

Polyamines as potential cancer markers in urine and blood.

open access: yes, 2021
Neoplastic diseases are the leading causes of death after cardiovascular diseases in the world. Therefore, an early cancer diagnosis is essential for cancer patients to have the best chances for successful treatment and improve the quality of life.

Polyamines control of cation transport across plant membranes: implications for ion homeostasis and abiotic stress signaling

open access: yesFrontiers in Plant Science, 2014
Polyamines are unique polycationic metabolites, controlling a variety of vital functions in plants, including growth and stress responses. Over the last two decades a bulk of data was accumulated providing explicit evidence that polyamines play an ...

Promotion of homology-directed DNA repair by polyamines

open access: yesNature Communications, 2019
The maintenance polyamines homeostasis is important for cell growth, and several cancers harbor elevated levels of polyamines that may contribute to sustained proliferative potential. Here the authors demonstrate that polyamines participate in DNA double-

Urinary Excretion of Free and Acetylated Polyamines in Hepatocellular Carcinoma

open access: yesThe International Journal of Biological Markers, 1998
Polyamines (putrescine, spermidine and spermine) are essential for the proliferation of normal and neoplastic cells, and have been repeatedly recommended as tumor markers, with contrasting and elusive results.

The old and new biochemistry of polyamines

open access: yes, 2018
Polyamines are ubiquitous positively charged amines found in all organisms. These molecules play a crucial role in many biological functions including cell growth, gene regulation and differentiation.

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

open access: yesFEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.
