The role of polyamines in response to abiotic stresses [PDF]
Under the influence of various abiotic stresses, the growth, development and geographic distribution of plants change. In order to survive adverse environmental conditions and to sustain life, plants have evolved various combat and adaptive strategies to

Influence of anti-hyperlipidemic activity by co-administration of polyamines and rutin with simvastatin [PDF]
Introduction: Natural polyphenols, rutin, endogenous polycations, and polyamines (spermine and spermidine) are reported to have beneficial effects on hyperlipidemia, obesity, and cardiovascular disease (CVD).

Polyamines Influence Mouse Sperm Channels Activity [PDF]
Polyamines are ubiquitous polycationic compounds that are highly charged at physiological pH. While passing through the epididymis, sperm lose their capacity to synthesize the polyamines and, upon ejaculation, again come into contact with the polyamines ...

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 as redox homeostasis regulators during salt stress in plants
The balance between accumulation of stress-induced polyamines and reactive oxygen species (ROS) is arguably a critical factor in plant tolerance to salt stress.

Urinary Excretion of Free and Acetylated Polyamines in Hepatocellular Carcinoma
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.

Polyamines in Halophytes [PDF]
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.
