Compartmentalisation in cAMP signalling: A phase separation perspective
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.

KYNU is upregulated in gastric cancer cells and activates the PI3K/Akt pathway, leading to PF4 secretion. PF4 drives nonclassical macrophage polarization with high expression of S100A8 and MMP7, which promotes tumor proliferation, migration, and invasion while suppressing phagocytosis, thereby accelerating gastric cancer progression.

Abstract Aim To identify shared and disorder‐specific molecular alterations across encephalitis, Aicardi–Goutières syndrome (AGS), and autism spectrum disorder (ASD) using cerebrospinal fluid (CSF) proteomics. Method In this cross‐sectional case–control study, mass‐spectrometry‐based proteomics was performed on archived CSF samples collected between ...

Ligand binding represses bacterial histidine kinase activity by inhibiting its dimerization
PdtaS is a kinase in the pathogen Mycobacterium tuberculosis that senses copper and nitric oxide and controls virulence gene expression, but how the kinase senses these compounds was unclear. We show that PdtaS is active as a dimer with each monomer phosphorylating the other in trans.

Proteostasis in the regulation of pancreatic islet cell plasticity
Adaptive proteostasis integrates protein synthesis, folding, trafficking, and degradation through ISR, UPR, ER stress responses, autophagy, and proteasomal degradation. In pancreatic islet cells, this coordinated network preserves protein quality, secretory function, proliferation, and survival, enabling adaptation to metabolic stress and aging while ...

ABSTRACT Aim The aim of this Phase I/II open‐label study was to assess the safety and efficacy of NTI164, a novel full‐spectrum medicinal cannabis plant extract 0.08% Δ‐9‐tetrahydrocannabinol (THC), in Rett syndrome (RTT). Methods Eleven female participants (5–16 years) with a pathogenic variant in the MECP2 gene were recruited to this study, receiving

ABSTRACT Developing barley grains must balance the use of imported sucrose between soluble sugars and storage starch, but how this balance is controlled remains unclear. Here we show that loss of the plastidial α‐glucan phosphorylase HvPHO1 causes starch and soluble sugars to accumulate concurrently in barley grains.
