Ghisalberti CA, Borzì RM, Cetrullo S, Flamigni F, Cairo G.
PMID: 27375482
Front Pharmacol. 2016 Jun 03;7:147. doi: 10.3389/fphar.2016.00147. eCollection 2016.

A reparative approach of disrupted epithelium in obstructive airway diseases, namely asthma and chronic obstructive pulmonary disease (COPD), may afford protection and long-lasting results compared to conventional therapies, e.g., corticosteroids or immunosuppressant drugs. Here, we propose the polyamine spermidine...

PMID: 28234336
Foods. 2014 Oct 09;3(4):541-557. doi: 10.3390/foods3040541.

Putrescine, spermidine and spermine are the most abundant polycationic natural amines found in nearly all organisms. They are involved in regulation of gene expression, translation, cell proliferation and differentiation. They can be supplied by the endogenous synthesis inside the...

Frontiers in plant science

Sobieszczuk-Nowicka E, Kubala S, Zmienko A, Małecka A, Legocka J.
PMID: 26779231
Front Plant Sci. 2016 Jan 06;6:1198. doi: 10.3389/fpls.2015.01198. eCollection 2015.

The aim of this study was to analyze whether polyamine (PA) metabolism is involved in dark-induced Hordeum vulgare L. 'Nagrad' leaf senescence. In the cell, the titer of PAs is relatively constant and is carefully controlled. Senescence-dependent increases in...

Spermidine is protective against kidney ischemia and reperfusion injury through inhibiting DNA nitration and PARP1 activation.

Anatomy & cell biology

Kim J.
PMID: 29043098
Anat Cell Biol. 2017 Sep;50(3):200-206. doi: 10.5115/acb.2017.50.3.200. Epub 2017 Sep 20.

Kidney ischemia and reperfusion injury (IRI) is associated with a high mortality rate, which is attributed to tubular oxidative and nitrative stresses; however, an effective approach to limit IRI remains elusive. Spermidine, a naturally occurring polyamine, protects yeast cells...

Sensors (Basel). 2018 Mar 08;18(3). doi: 10.3390/s18030814.

The synthesis of two new azobenzene dyes, namely CR-528 and CR-555, and their spectral properties in ethanol solution are described. The recognition of sulfur-containing analytes (2-mercaptoethanol (2-ME), sodium hydrosulfide (NaHS)), and biogenic amines (spermine, spermidine, ethanolamine) bestowed significant spectral...

Exogenous spermidine alleviates oxidative damage and reduce yield loss in rice submerged at tillering stage.

Frontiers in plant science

Liu M, Chu M, Ding Y, Wang S, Liu Z, Tang S, Ding C, Li G.
PMID: 26583021
Front Plant Sci. 2015 Oct 31;6:919. doi: 10.3389/fpls.2015.00919. eCollection 2015.

To figure out whether spermidine (Spd) can alleviate oxidative damage on rice (Oryza sativa L.) caused by submergence stress, Ningjing 3 was used in this study. The results showed that, spraying Spd on rice leaves at a concentration of...

Kinetics and calcium-specificity of polyamine uptake in carrot protoplasts.

Amino acids

Antognoni F, Casali P, Pistocchi R, Bagni N.
PMID: 24189738
Amino Acids. 1994 Oct;6(3):301-9. doi: 10.1007/BF00813750.

The kinetics of putrescine and spermidine uptake and the influence of calcium on the kinetic parameters of the transport process were investigated in protoplasts isolated from carrot phloem parenchyma. Spermidine uptake dependence on external concentration was biphasic, both in...
