Characterisation of multiple substrate-specific (d)ITP/(d)XTPase and modelling of deaminated purine nucleotide metabolism [PDF]

open access: yes, 2011
To be viable, organisms possess a number of (deoxy)nucleotide phosphohydrolases, which hydrolyze these nucleotides removing them from the active NTP and dNTP pools. Deamination of purine bases can result in accumulation of such nucleotides as ITP, dITP,

Single‐base methylome profiling of the giant kelp Saccharina japonica reveals significant differences in DNA methylation to microalgae and plants

open access: yesNew Phytologist, Volume 225, Issue 1, Page 234-249, January 2020., 2020
Summary Brown algae have convergently evolved plant‐like body plans and reproductive cycles, which in plants are controlled by differential DNA methylation. This contribution provides the first single‐base methylome profiles of haploid gametophytes and diploid sporophytes of a multicellular alga. Although only c.

Development of a machine learning potential for nucleotides in water [PDF]

open access: yes, 2022
Recent experimental research showed that nucleotides, under favorable conditions of temperature and concentration, can self-assemble into liquid crystals. The mechanism involves the stacking of nucleotides into columnar aggregates. It has been proposed

The effect of extracellular nucleotides on cytokine production and phagocytosis of macrophages [PDF]

open access: yes, 2014
Bacterial sepsis is a severe clinical condition, leading to severe sepsis, septic shock, and death. The complex pathophysiology of sepsis is not yet fully understood.

Extracellular Nucleotides in the Regulation of Kidney Functions

open access: yes, 2013
ATP is normally regarded as the major source of fuel for the energy-demanding processes within cells; however, ATP and other nucleotides (such as ADP, UTP, UDP) can be released from cells, where they act as autocrine or paracrine signaling molecules to ...

Contribution of DNA/RNA Structures Formed by Expanded CGG/CCG Repeats Within the FMR1 Locus in the Pathogenesis of Fragile X‐Associated Disorders

open access: yesWIREs RNA, Volume 15, Issue 6, November/December 2024.
CGG repeat expansion may occur in the 5′ untranslated region of the FMR1 gene. The resulting mutant DNA and RNA with expanded CGG repeats form stable secondary structures that can interfere with numerous cellular processes. Depending on the length of the CGG repeats, different molecular phenotypes may occur, which in turn determine different clinical ...

Sulforaphane‐induced metabolomic responses with epigenetic changes in estrogen receptor positive breast cancer cells

open access: yesFEBS Open Bio, Volume 8, Issue 12, Page 2022-2034, December 2018., 2018
Sulforaphane (SFN) may be a promising chemopreventive agent. We investigated the metabolic profiles of MCF‐7 cells with estrogen (E2) and/or SFN treatment by GC‐MS and UPLC‐Orbitrap‐MS methods. The data showed that SFN can reverse the E2‐induced changes in amino acid, purine, and folic acid metabolism, as well as glycolysis and energy metabolism, and ...

Analysis of Nucleosides and Nucleotides in Milk and Infant Formula [PDF]

open access: yes, 2013
Nucleotides have been routinely supplemented to infant formulas due to the important roles they play in metabolism and to replicate the higher concentrations typically found in human milk.

On the chemistry of sunlight‐induced DNA lesions: A perspective on the alkaline chemical‐induced reactivities of photo‐damaged pyrimidine intra‐strand dimers

open access: yesPhotochemistry and Photobiology, Volume 100, Issue 6, Page 1698-1712, November/December 2024.
UV photoexcitation of adjacent intra‐strand pyrimidines in DNA can promote their covalent dimerization at sites such as 5′‐T‐p‐T‐3′ and 5′‐T‐p‐C‐3′. This photo‐reactivity leads, notably, to cyclobutane pyrimidine dimers, pyrimidine (6‐4) pyrimidone photoproducts (6‐4PPs), and, in bacterial endospores, the spore photoproduct, SP.

Risks for public health related to the presence of furan and methylfurans in food

open access: yesEFSA Journal, Volume 15, Issue 10, October 2017., 2017
Abstract The European Commission asked EFSA for a scientific evaluation on the risk to human health of the presence of furan and methylfurans (2‐methylfuran, 3‐methylfuran and 2,5‐dimethylfuran) in food. They are formed in foods during thermal processing and can co‐occur.
