Cross-Talk between Dnmt2-Dependent tRNA Methylation and Queuosine Modification

Biomolecules, 2017
Enzymes of the Dnmt2 family of methyltransferases have yielded a number of unexpected discoveries. The first surprise came more than ten years ago when it was realized that, rather than being DNA methyltransferases, Dnmt2 enzymes actually are transfer ...

Lactate Signal: Modulator of Cellular Energy Production and Anabolism

Advanced Science, EarlyView.
Compartmentalized lactate signaling provides a spatial framework for understanding how lactate‐rich states are generated, transported, sensed, and translated into biological outputs. This Review integrates extracellular, cytosolic, mitochondrial‐associated, and nuclear lactate mechanisms to explain how lactate shapes metabolic adaptation, immune ...

β‐Adducin Restrains PLA2G4A‐Dependent Lysosomal Membrane Permeabilization and Neuronal Death in Ischemic Stroke

Advanced Science, EarlyView.
This study identifies β‐adducin as a regulator of lysosomal integrity in ischemic neurons. Ischemia‐associated FTO loss increases m6A modification and destabilizes Add2 mRNA, reducing β‐adducin expression and promoting PLA2G4A accumulation at lysosomes.

Hepatic Lipid Stress Drives Metabolic Dysfunction‐Associated Steatohepatitis Progression through FTO O‐GlcNAcylation‐Induced m6A Demethylation of HRAS

Advanced Science, EarlyView.
Lipid stress drives O‐GlcNAcylation of the m6A demethylase FTO at Ser195, enhancing its stability and demethylase activity. This modification removes m6A from HRAS mRNA, preventing its degradation and activating PI3K/AKT signaling to promote hepatic steatosis and inflammation.

NSUN3‐Associated m5C Modification of tRF5‐GlyTCC Suppresses Colorectal Cancer Progression via RPL23‐Linked Nucleolar Stress and p53‐Associated Autophagy and Enhances 5‐FU Sensitivity

Advanced Science, EarlyView.
This study identifies that NSUN3‐mediated m5C modification stabilizes tRF5‐GlyTCC, linking ribosomal homeostasis, nucleolar stress responses, and p53 signaling changes. This regulatory axis suppresses colorectal cancer and enhances chemotherapy response to 5‐FU, positioning tRF5‐GlyTCC as a potential therapeutic target for improving drug sensitivity in

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 ...

Improving genetic diagnosis of hereditary tumor syndromes: From expanded gene panels to functional genomics

International Journal of Cancer, EarlyView.
Abstract Genetic tumor risk syndromes (genturis) contribute substantially to the overall cancer burden and provide opportunities for early detection, prevention, and individualized treatment. Yet, many affected individuals remain undiagnosed due to restrictive testing criteria and challenges in variant interpretation.
