HR‐MS Analysis of the Covalent Binding of Edaravone to 5‐Formylpyrimidine Bases and a DNA Oligonucleotide Containing a 5‐Formylcytidine Residue

open access: yesRapid Communications in Mass Spectrometry, Volume 39, Issue 14, 30 July 2025.
ABSTRACT Rationale Edaravone (EDA) is a radical scavenger and an antioxidant drug approved to treat amyotrophic lateral sclerosis and used as a research tool to explore treatment of neurodegenerative diseases and cancers. It is also a reactive agent, known as PMP (1‐phenyl‐3‐methyl‐5‐pyrazolone), used for the analysis of polysaccharides composition ...

Organic Hazes as a Source of Life’s Building Blocks to Warm Little Ponds on the Hadean Earth

open access: yesThe Planetary Science Journal
Over 4 billion years ago, Earth is thought to have been a hazy world akin to Saturn’s moon Titan. The organic hazes in the atmosphere at this time could have contained a vast inventory of life’s building blocks and thus may have seeded warm little ponds ...

ERNEST COST action overview on the (patho)physiology of GPCRs and orphan GPCRs in the nervous system

open access: yesBritish Journal of Pharmacology, Volume 182, Issue 14, Page 3178-3210, July 2025.
G protein‐coupled receptors (GPCRs) are a large family of cell surface receptors that play a critical role in nervous system function by transmitting signals between cells and their environment. They are involved in many, if not all, nervous system processes, and their dysfunction has been linked to various neurological disorders representing important

Prevalence and Whole Genome Sequence Analysis of Mycoplasma bovis Isolates From Bulk Tank Milk of Dairy Farms in Tennessee, USA

open access: yesJournal of Veterinary Internal Medicine, Volume 39, Issue 4, July/August 2025.
ABSTRACT Background Mycoplasma bovis mastitis is an important disease of dairy cows that causes substantial economic losses. However, its prevalence in different states in the United States (US), including Tennessee, is not well known. Furthermore, recent studies showed a high prevalence of bovine hemotropic mycoplasmas in US dairy farms.

Multiple transitions to high l‐DOPA 4,5‐dioxygenase activity reveal molecular pathways to convergent betalain pigmentation in Caryophyllales

open access: yesNew Phytologist, Volume 247, Issue 1, Page 341-357, July 2025.
Summary Many specialized metabolic pathways have evolved convergently in plants, but distinguishing multiple origins from alternative evolutionary scenarios can be difficult. Here, we explore the evolution of l‐3,4‐dihydroxyphenylalanine (l‐DOPA) 4,5‐dioxygenase (DODA) enzymes to better resolve the convergent evolution of the betalain biosynthetic ...

The Direct and Individual Transcriptional Function of the Human Homodimeric and Heterodimeric Basic Helix–Loop–Helix Transcription Factors E47 and Scleraxis

open access: yesThe FASEB Journal, Volume 39, Issue 12, 30 June 2025.
The isolated yeast model allowed visualization of the function of the heterodimeric SCX and E47 transcription factors (TFs) in the absence of other interacting proteins. The findings support the need for additional transcription factor binding sites (TFBS) and a permissive chromatin landscape for these TFs to exert a positive transcriptional effect ...

Phylogenetic analysis of the promoter element 2 of paramyxo- and filoviruses

open access: yesMicrobiology Spectrum
Paramyxo- and filovirus genomes are equipped with bipartite promoters at their 3' ends to initiate RNA synthesis. The two elements, the primary promoter element 1 (PE1) and the secondary promoter element 2 (PE2), are separated by a spacer region that ...
