The CshA DEAD-box RNA helicase is important for quorum sensing control in Staphylococcus aureus

, 2013
DEAD-box RNA helicases are present in almost all living organisms and participate in various processes of RNA metabolism. Bacterial proteins of this large family were shown to be required for translation initiation, ribosome biogenesis and RNA decay. The

Inhibin βB Mediates Oligotrophic Adaptation via Regulating Muscle Satellite Cell Proliferation and Differentiation in Schizopygopsis younghusbandi

Integrative Zoology, EarlyView.
① Nutrient deficiency upregulates inhibin βB, activating SMAD signaling to promote p21. Increased p21 inhibits mcm2/mcm4/mcm5 and cyclin E2, inducing G1‐phase arrest, slowing growth, and reducing energy consumption. ② Inhibin βB also upregulates pdgf‐c, which induces α‐SMA, leading to muscle satellite cell fibrosis.

The DEAD-Box RNA Helicases of Bacillus subtilis as a Model to Evaluate Genetic Compensation Among Duplicate Genes

Frontiers in Microbiology, 2018
The presence of duplicated genes in organisms is well documented. There is increasing interest in understanding how these genes subfunctionalize and whether functional overlap can explain the fact that some of these genes are dispensable.

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.

Role of DEAD/DEAH-box helicases in immunity, infection and cancers

Cell Communication and Signaling
DEAD/DEAH-box helicases (DDX) are integral RNA-binding proteins within the RNA helicase superfamily 2 (SF2), characterized by distinct DEAD (Asp-Glu-Ala-Asp) and DEAH (Asp-Glu-Ala-His) motifs.

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.

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.
