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.

Structure of METTL3-METTL14 with an m6A nucleotide reveals insights into m6A conversion and sensing

Abstract The nuclear METTL3-METTL14 transfers a methyl group from SAM to convert the N6 of adenosine (A) in RNA to m6A and in ssDNA to 6mA. m6A marks are prevalent in eukaryotic mRNAs and lncRNAs and modulate their stability and fate in a context-dependent manner. The cytoplasmic METTL3 can act as a m6A reader.

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.

RBMS1 Contributes to Early Arteriovenous Fistula Neointimal Remodeling Through Modulation of VSMC Phenotypic Responses

Advanced Science, EarlyView.
Postoperative arteriovenous fistulas exhibit increased RBMS1 in vascular smooth muscle cells (VSMCs). In experimental AVFs, RBMS1 overexpression aggravates, whereas deletion attenuates, neointimal hyperplasia. RBMS1 binds MPZL1 mRNA and promotes exon 5 skipping to generate MPZL1‐Δ5, which interacts with G3BP1 to activate AKT, driving VSMC proliferation,

METTL3-mediated miR-4534 maturation promotes IVDD progression by targeting the Sirt6-mediated Nrf2/HO-1 pathway

Archives of Medical Science
Introduction Intervertebral disc degeneration (IVDD) is a significant contributor to the development of discogenic low back pain and impairment. Apoptosis and degradation of the extracellular matrix (ECM) have also been reported to be major factors in ...

Deregulation and delocalization of the m6A demethylase FTO and aberrant m6A levels in ccRCC tissue samples.

Histology and histopathology
N6-methyladenosine (m6A) is one of the most abundant mRNA modifications established by the activity of three classes of enzymes: writers, readers, and erasers. The relevance of m6A in the regulation of gene expression implies its key role in normal biological processes and cancer development.

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 ...
