DDX1 is required for non-spliceosomal splicing of tRNAs but not of XBP1 mRNA

Communications Biology
RNA helicase DEAD-box helicase 1 (DDX1) forms a complex with the RNA ligase 2´,3´-cyclic phosphate and 5´-OH ligase (RTCB), which plays a vital role in non-spliceosomal splicing of tRNA and X-box binding protein 1 (XBP1) mRNA.

Functional assessment of inherited myeloid neoplasm‐associated SAMD9L germline variants via Monoallelic CRISPR modelling

British Journal of Haematology, EarlyView.
Summary While the majority of myeloid neoplasms are sporadic, the increasing application of germline genetic testing has led the World Health Organization to designate ‘Myeloid malignancies with germline predisposition’ as a distinct clinical entity, carrying major implications for clinical care and research.

Compartmentalisation in cAMP signalling: A phase separation perspective

British Journal of Pharmacology, EarlyView.
Cells rely on precise spatiotemporal control of signalling pathways to ensure functional specificity. The compartmentalisation of cyclic AMP (cAMP) and protein kinase A (PKA) signalling enables distinct cellular responses within a crowded cytoplasmic space.

tRNA‐Derived Small RNAs in Digestive Cancers: From Translational Regulation to Immune and Extracellular Communication

Cancer Science, EarlyView.
tRNA‐derived small RNAs (tsRNAs) function in digestive cancers across three scales: intracellular translational and metabolic control, extracellular vesicle–mediated immune remodeling, and systemic and host–microbe communication. This review organizes these mechanisms by evidence strength, from well‐established intracellular roles to emerging ...

PABPC1 in Cancer: From a Translational Housekeeper to a Stress‐Responsive Regulatory Hub

Cancer Science, EarlyView.
PABPC1 shifts from a translational housekeeper to a stress‐responsive oncogenic hub via phase separation, PTMs, and non‐coding RNA crosstalk, selectively driving oncogene translation and therapy resistance in cancer. ABSTRACT PABPC1, long recognized as a constitutive translational housekeeper, has emerged as a stress‐responsive translational ...

Methyl 4‐O‐Demethylbarbatate Destabilises HIF‐1α and Enhances Temozolomide Sensitivity in Glioma Cells

Cell Proliferation, EarlyView.
The lichen‐derived metabolite methyl 4‐O‐demethylbarbatate (Me‐4‐O‐DBA) suppresses glioma stemness, motility, and metabolic plasticity through inhibition of HIF‐1α signaling and synergistically enhances temozolomide activity, highlighting a potential strategy to target stemness‐driven therapeutic resistance in glioma.

Repositioning Non‐Ablative Fractional Lasers ‐ Molecular and Histological Insights from a scoping review

JDDG: Journal der Deutschen Dermatologischen Gesellschaft, EarlyView.
Summary Near‐infrared non‐ablative fractional lasers (NAFL) are established for skin rejuvenation and scar treatment and have attracted interest for their expanding therapeutic potential. This scoping review aims to revisit and reposition NAFL within a fluence‐dependent continuum of tissue modulation, based on evidence from 27 studies of lasers ...

A structural model for the DEAD box helicase YxiN in solution : localization of the RNA-binding domain

, 2010
DEAD box proteins consist of a common helicase core, formed by two globular RecA domains that are separated by a cleft. The helicase core acts as a nucleotide-dependent switch that alternates between open and closed conformations during the catalytic ...

Chd4 and ThPOK cooperate to preserve structural and electrophysiological integrity of the adult heart through Sprr1a repression

The FEBS Journal, EarlyView.
Chd4/NuRD and ThPOK cooperate to maintain transcriptional repression and nuclear organization in adult cardiomyocytes. Chd4 loss reduces miR‐150‐5p, relieving repression of Sprr1a, while ThPOK loss further enhances Sprr1a activation, possibly through altered chromatin–lamina interactions.

TOP1MT rs2293925 is an enhancer‐active regulatory SNP that shapes mitochondrial R‐loop dynamics

The FEBS Journal, EarlyView.
This study shows how a common genetic variant of mitochondrial topoisomerase 1 (TOP1MT rs2293925) can influence mitochondrial gene regulation, DNA topology, and formation of noncanonical nucleic acid structures such as R‐loops. By linking this enhancer‐active variant to mitochondrial nucleic acid stress in cellular contexts relevant to amyotrophic ...
