tRNA modifications and tRNA-derived small RNAs: new insights of tRNA in human disease

Cell Biology and Toxicology
tRNAs are codon decoders that convert the transcriptome into the proteome. The field of tRNA research is excited by the increasing discovery of specific tRNA modifications that are installed at specific, evolutionarily conserved positions by a set of specialized tRNA-modifying enzymes and the biogenesis of tRNA-derived regulatory fragments (tsRNAs ...

RNA‐centric world of retroviruses: unravelling the molecular strategies of genomic RNA packaging

Biological Reviews, EarlyView.
ABSTRACT Retroviruses constitute a unique group of RNA viruses that have profoundly influenced both evolutionary trajectories and biomedical research. Their ability to reverse transcribe and integrate into host genomes has shaped genomic architecture across species and contributed to our understanding of oncogenes, gene regulation, and RNA biology ...

Hybrid Macrocyclic Peptides — Synthetic Strategies to Diversify and Cyclize Peptide Libraries in Phage Display Selections

Chemistry – A European Journal, EarlyView.
Hybrid macrocyclic peptides unite genetically encoded peptide libraries with the structural complexity of synthetic small molecules. This Review critically analyzes phage‐compatible cyclization and diversification chemistries, highlights emerging opportunities beyond traditional cysteine‐based approaches, and outlines how future advances may enable the

Proteomic profiling of Elp1‐deficient trigeminal ganglia reveals disruption of neurotrophic and metabolic pathways in a familial dysautonomia mouse model

Developmental Dynamics, EarlyView.
Abstract Background Elp1, a subunit of the Elongator complex, is essential for tRNA modification and neuronal development. Mutations in ELP1 underlie familial dysautonomia (FD), a disorder marked by sensory and autonomic neuropathy. While loss of Elp1 disrupts trigeminal ganglion formation and survival, the downstream molecular consequences remain ...

Decoding human tRNA modifications and crosstalk by enhanced single-read analysis

Genome Biology
Background Transfer RNA (tRNA) modifications play important roles in regulating gene expression and protein synthesis, yet their dynamic interplay remains elusive.

Three‐dimensional observation of the muscle–tendon integration process in mouse embryos

Developmental Dynamics, EarlyView.
Abstract Background Muscle–tendon integration is a crucial step in the morphogenesis of the vertebrate locomotion system. As the limb muscle and tendon progenitor cells derive from distinct embryonic origin, their integration requires precise mutual positioning.

E. coli MnmA Is an Fe-S Cluster-Independent 2-Thiouridylase

Inorganics
All kingdoms of life have more than 150 different forms of RNA alterations, with tRNA accounting for around 80% of them. These chemical alterations include, among others, methylation, sulfuration, hydroxylation, and acetylation.

Translational regulation by oxidative desulfuration of tRNA modifications

Nature Communications
Modifications in the anticodon region of transfer RNA (tRNA) are essential for accurate and efficient protein synthesis. 5-Methyl-2-thiouridine derivatives (xm5s2U) are major modifications at the wobble position of tRNA anticodons decoding purine-ending two-codon sets.

Role of selenium in the pathophysiology of cardiorenal anaemia syndrome

ESC Heart Failure, Volume 12, Issue 2, Page 770-780, April 2025.
Abstract Chronic kidney disease (CKD) and cardiovascular disease (CVD) have multiple bidirectional mechanisms, and anaemia is one of the critical factors that are associated with the progression of the two disorders [referred to as cardiorenal anaemia syndrome (CRAS)].

Vaginal host–microbe signatures linked to placental outcomes in mares

Equine Veterinary Journal, EarlyView.
Abstract Background Ascending placentitis is a leading cause of late‐term pregnancy loss in mares. Although pathogens are presumed to ascend from the caudal reproductive tract, the association between the vaginal microbiome and placentitis has not been systematically examined.
