Spermidine cures yeast of prions [PDF]

open access: yesMicrobial Cell, 2016
Prions are self-perpetuating amyloid protein aggregates which underlie various neurodegenerative diseases in mammals. The molecular basis underlying their conversion from a normally soluble protein into the prion form remains largely unknown. Studies aimed at uncovering these mechanism(s) are therefore essential if we are to develop effective ...

Natural Polyamine Spermidine Inhibits the In Vitro Oxidation of LDL

open access: yesMolecules
Spermidine is a natural autophagy-inducer and anti-aging compound. Herein, we investigated a potential autophagy-independent mechanism of spermidine, namely its capability to directly impede LDL oxidation, an early step in atherogenesis.

Research Progress and Potential Applications of Spermidine in Ocular Diseases

open access: yesPharmaceutics, 2022
Spermidine, a natural polyamine, exists in almost all human tissues, exhibiting broad properties like anti-aging, autophagy induction, anti-inflammation, anti-oxidation, cell proliferation activation, and ion channel regulation.

Spermidine Modify Antioxidant Activity in Cucumber Exposed to Salinity Stress

open access: yesAgronomy, 2022
The effects of short-term 48 h long NaCl-stress and spermidine level modification on polyamines level and antioxidant status in cucumber (Cucumis sativus cv. Dar) leaves were investigated.

Molecular targets of spermidine: implications for cancer suppression

open access: yesCell Stress, 2023
Spermidine is a ubiquitous, natural polyamine with geroprotective features. Supplementation of spermi-dine extends the lifespan of yeast, worms, flies, and mice, and dietary spermidine intake correlates with reduced human mortality.

Spermidine Mitigates Immune Cell Senescence and Boosts Vaccine Responses in Healthy Older Adults-A Pilot Study. [PDF]

open access: yesAging Cell
Can we boost vaccine responses in older adults? In a double‐blind, randomised, placebo‐controlled pilot study (n = 40, > 65 years), spermidine supplementation (6 mg/day, 13 weeks) was safe and significantly improved immune responses following a 3rd SARS‐CoV‐2 vaccine dose.

Identification of functional amino acid residues involved in polyamine and agmatine transport by human organic cation transporter 2. [PDF]

open access: yesPLoS ONE, 2014
Polyamine (putrescine, spermidine and spermine) and agmatine uptake by the human organic cation transporter 2 (hOCT2) was studied using HEK293 cells transfected with pCMV6-XL4/hOCT2.

Exogenous spermidine affects polyamine metabolism in the mouse hypothalamus

open access: yesOpen Life Sciences, 2021
Spermidine is important for the hypothalamic control of pituitary secretion of hormones involved in neuroendocrine functions in mammals. In this study, the effect of exogenous spermidine on the expression of genes and proteins related to polyamine ...

Spermidine Is an Intercellular Signal Modulating T3SS Expression in Pseudomonas aeruginosa

open access: yesMicrobiology Spectrum, 2022
Pseudomonas aeruginosa is a vital opportunistic human bacterial pathogen that causes acute and chronic infections. In this study, we set to determine whether the endogenous spermidine biosynthesis plays a role in regulation of type III secretion system ...
