Epigenetics and autoimmune diseases: the X chromosome-nucleolus nexus.

Frontiers in genetics

Brooks WH, Renaudineau Y.
PMID: 25763008
Front Genet. 2015 Feb 16;6:22. doi: 10.3389/fgene.2015.00022. eCollection 2015.

Autoimmune diseases occur more often in females, suggesting a key role for the X chromosome. X chromosome inactivation, a major epigenetic feature in female cells that provides dosage compensation of X-linked genes to avoid overexpression, presents special vulnerabilities that...

Transport Properties of Amine/Carbon Dioxide Reactive Mixtures and Implications to Carbon Capture Technologies.

ACS applied materials & interfaces

Turgman-Cohen S, Giannelis EP, Escobedo FA.
PMID: 26200117
ACS Appl Mater Interfaces. 2015 Aug 19;7(32):17603-13. doi: 10.1021/acsami.5b04153. Epub 2015 Aug 05.

The structure and transport properties of physisorbed and chemisorbed CO2 in model polyamine liquids (hexamethylenediamine and diethylenetriamine) are studied via molecular dynamics simulations. Such systems are relevant to CO2 absorption processes where nonaqueous amines are used as absorbents (e.g.,...

A Cross-Sectional Study: Nutritional Polyamines in Frequently Consumed Foods of the Turkish Population.

Foods (Basel, Switzerland)

Buyukuslu N, Hizli H, Esin K, Garipagaoglu M.
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...

From Accumulation to Degradation: Reprogramming Polyamine Metabolism Facilitates Dark-Induced Senescence in Barley Leaf Cells.

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...

Polyamines directly promote antizyme-mediated degradation of ornithine decarboxylase by the proteasome.

Microbial cell (Graz, Austria)

Beenukumar RR, Gödderz D, Palanimurugan R, Dohmen RJ.
PMID: 28357293
Microb Cell. 2015 May 20;2(6):197-207. doi: 10.15698/mic2015.06.206.

Ornithine decarboxylase (ODC), a ubiquitin-independent substrate of the proteasome, is a homodimeric protein with a rate-limiting function in polyamine biosynthesis. Polyamines regulate ODC levels by a feedback mechanism mediated by ODC antizyme (OAZ). Higher cellular polyamine levels trigger the...

Achiral polyamine-induced chiral zinc gallophosphates with fused double helix-like strands exhibiting blue to green photoluminescence.

Dalton transactions (Cambridge, England : 2003)

Huang HL, Liu YR, Huang LH, Chiang RK, Wang SL.
PMID: 29068024
Dalton Trans. 2017 Nov 14;46(44):15186-15189. doi: 10.1039/c7dt02465g.

This study found non-chiral polyamines to be effective in inducing chiral frameworks. Four zinc gallophosphates with a chiral UCSB-7 topology were generated from the use of four different linear-chain polyamines as templates. In the structure, helical inorganic strands and...

Characterization of pea histone deacetylases.

Plant molecular biology

Sendra R, Rodrigo I, Salvador ML, Franco L.
PMID: 24272635
Plant Mol Biol. 1988 Nov;11(6):857-66. doi: 10.1007/BF00019525.

The present paper is the first report on histone deacetylases from plants. Three enzyme fractions with histone deacetylase activity (HD0, HD1 and HD2) have been partially purified from pea (Pisum sativum) embryonic axes. They deacetylate biologically acetylated chicken histones...

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

Frontiers in plant science

Pottosin I, Shabala S.
PMID: 24795739
Front Plant Sci. 2014 Apr 23;5:154. doi: 10.3389/fpls.2014.00154. eCollection 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 essential role in...

Rol genes alter hormonal requirements for protoplast growth and modify the expression of an auxin responsive promoter.

Plant cell reports

Walden R, Czaja I, Schmülling T, Schell J.
PMID: 24201783
Plant Cell Rep. 1993 Aug;12(10):551-4. doi: 10.1007/BF00233058.

Growth characteristics of tobacco protoplasts containing rolA linked to its own promoter, or the rolB, or rolC genes of Agrobacterium rhizogenes linked to the Cauliflower Mosaic Virus 35S RNA promoter were compared with those from untransformed plants. RolA protoplasts...

Electrostatic interplay: The interaction triangle of polyamines, silicic acid, and phosphate studied through turbidity measurements, silicomolybdic acid test, and (29)Si NMR spectroscopy.

Beilstein journal of nanotechnology

The discovery of long-chain polyamines as biomolecules that are tightly associated to biosilica in diatom cell walls has inspired numerous in vitro studies aiming to characterize polyamine-silica interactions. The determination of these interactions at the molecular level is of...

Polyamines and abiotic stress in plants: a complex relationship.

Front Plant Sci. 2014 May 05;5:175. doi: 10.3389/fpls.2014.00175. eCollection 2014.

The physiological relationship between abiotic stress in plants and polyamines was reported more than 40 years ago. Ever since there has been a debate as to whether increased polyamines protect plants against abiotic stress (e.g., due to their ability...
