Context-specific Angiogenin-mediated tRNA fragments (tDRs) biogenesis shapes the mitochondrial stress response

Redox Biology
Transfer RNA-derived small RNAs (tDRs) are emerging regulators of cellular stress response, yet their biogenesis and activities during mitochondrial dysfunction remain poorly understood.

Oocyte–cumulus cell interaction: a key factor in early embryo development

Biological Reviews, EarlyView.
ABSTRACT The evaluation of oocyte competence is a fundamental step in achieving successful outcomes following assisted reproduction techniques (ART). At present, however, conventional oocyte maturation assessment is carried out by morphological observation, which is a subjective method that does not consider molecular features.

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

Communication Analysis of tRNA-Derived Fragment Uptake and Signalling in Neurons

2025 13th International Conference on Bioinformatics and Computational Biology (ICBCB)
This paper examines the role of tRNA-derived fragments (tRFs) in molecular communications and their potential as biomarkers and therapeutic targets in epilepsy. Recent studies have shown that three specific tRFs: 5′AlaTGC, 5′GluCTC, and 5′GlyGCC, are released from neurons and are elevated in epilepsy patients, before being taken up by neurons to ...

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 ...

The mitochondrial tRNA-derived fragment, mt-tRF-LeuTAA, couples mitochondrial metabolism to insulin secretion

Molecular Metabolism
Objective: The contribution of the mitochondrial electron transfer system to insulin secretion involves more than just energy provision. We identified a small RNA fragment (mt-tRF-LeuTAA) derived from the cleavage of a mitochondrially-encoded tRNA that ...

N6‐Methyladenosine in Inflammatory Bowel Disease: An Emerging Regulator of Pathogenesis and a Novel Therapeutic Frontier

iMetaMed, EarlyView.
Inflammatory bowel disease (IBD) is a chronic inflammatory disorder of the intestine associated with an imbalance in intestinal homeostasis. m6A‐modifying enzymes, consisting of m6A writers, erasers and readers, plays a pivotal role in the pathogenesis and progression of IBD by affecting four intestinal barriers, including the intestinal mechanical ...

Deep sequencing of yeast and mouse tRNAs and tRNA fragments using OTTR

eLife
Among the major classes of RNAs in the cell, tRNAs remain the most difficult to characterize via deep sequencing approaches, as tRNA structure and nucleotide modifications can each interfere with cDNA synthesis by commonly used reverse transcriptases ...

Strategies and mechanisms of precision genome engineering: From gene editing to genome writing

iMetaOmics, EarlyView.
In this review, we examined the progression of genome manipulation from stochastic nuclease‐mediated cutting toward precise editing and programmable genome writing. We discussed tools like multi‐kilobase RNA‐guided integrators and Artificial Intelligence (AI)‐designed effectors and showed how these advances enable researchers to treat genomes as ...

Transfer RNA expression, modification, and derived small RNAs in cancer biology and clinical potential

Frontiers in Immunology
Transfer RNA (tRNA) is essential for protein synthesis and undergoes diverse chemical modifications that regulate its stability and function. Dysregulation of tRNA expression and modifications, along with the activity of tRNA-derived small RNAs (tsRNAs ...
