Compartmentalisation in cAMP signalling: A phase separation perspective

open access: yesBritish 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

open access: yesCancer 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 ...

The DNA/RNA Helicase SETX Maintains R‐Loop Homeostasis to Promote Chemoresistance in Ovarian Cancer

open access: yesCancer Science, EarlyView.
SETX maintains R‐loop homeostasis by resolving excessive R‐loops, thereby promoting tumor initiation and chemoresistance. Deficiency of SETX leads to accumulation of unsolved pathological R‐loops, resulting in irreparable DNA damage and ultimately leading to tumor suppression and chemosensitivity.

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

open access: yesCancer 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

open access: yesCell 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.
