Protein‐Independent Liquid–Liquid Phase Separation of Adenosine Triphosphate Under Crowded Conditions

Chemistry – A European Journal, EarlyView.
ATP itself is able to undergo liquid–liquid phase separation in the presence of the macromolecular crowding agent PEG and physiological ATP concentrations are sufficient for phase separation in the presence of mM Mg2+ and crowders, mimicking intracellular conditions.

Red Blood Cell Adenylate Energetics Is Related to Endothelial and Microvascular Function in Long COVID

Biomedicines
Adenine nucleotides play a critical role in maintaining essential functions of red blood cells (RBCs), including energy metabolism, redox status, shape fluctuations and RBC-dependent endothelial and microvascular functions.

Adenine Nucleotide Levels in a Closed Enzymatic Digestion System for Porcine Islet Isolation

Cell Transplantation, 2012
Obtaining viable islets is a crucial step for successful islet transplantation. Adenosine triphosphate (ATP) is a marker of cell viability. However, little is known about any changes in the energy status of the tissues that are being digested during the ...

A Cytosine‑Bulged (3+1) Hybrid G‑Quadruplex Formed by the Chicken DNA Replication Origin

Chemistry – A European Journal, EarlyView.
The first high‐resolution structure of an OGRE‐derived G‐quadruplex from the chicken β‐globin replication origin reveals an intramolecular three‐layer (3+1) hybrid fold with a cytosine bulge and an unprecedented 5'‐outer‐quartet anti guanine, creating a distinctive surface for molecular recognition.

Raman Optical Activity as a Tool to Monitor Polynucleotide Conformation in Solutions

Chemistry – A European Journal, EarlyView.
Raman optical activity (ROA) studies of nucleic acids have been hindered by limited computational tools to link the spectra to the structure. The study shows that accurate density functional simulations are possible for model nucleotides, bringing more information about molecular geometry and dynamics in solutions.

Formation of Lanthanide Luminescent Aggregates With RNA Using Tripodal Europium [Eu(III)] BTA Self‐Assembled Complexes

Chemistry – A European Journal, EarlyView.
The two Eu(III) complexes of 1.Eu and 2.Eu, that were formed in situ, were used to bind to yeast RNA and A10 (RNA) in a buffered pH 7 solution. The interaction gave rise to changes in the lanthanide‐centered emission because of direct binding of these complexes, which resulted in aggregation of the RNA, as demonstrated using phase‐contrast and atomic ...

A single nucleotide polymorphism produces different transcription profiles in Campylobacter jejuni’s cysM

Frontiers in Microbiology
A single nucleotide polymorphism (SNP) in the 126 bp untranslated region (UTR) directly upstream of Campylobacter jejuni’s cysM (cysteine synthase) results in significant effects on gene transcription.

Metabolic abnormalities and reprogramming in cats with naturally occurring hypertrophic cardiomyopathy

ESC Heart Failure, Volume 12, Issue 2, Page 1256-1270, April 2025.
Abstract Background and aims The heart is a metabolic organ rich in mitochondria. The failing heart reprograms to utilize different energy substrates, which increase its oxygen consumption. These adaptive changes contribute to increased oxidative stress.

[Adenine nucleotides in migraine].

Neurologia (Barcelona, Spain), 1991
Several studies have shown that migraine is associated with an abnormal platelet activation state, characterized by increased plasma levels of platelet BTG and PF4 proteins. Adenine nucleotides are contained in platelets as a part of the dense granules released during platelet activation.
