Tumor cell membrane camouflaged liposomal pharmaceuticals for cascade catalysis‐driven redox modulation and synergistic ROS/RNS antitumor therapy

VIEW, EarlyView.
A tumor cell membrane camouflaged liposomal nanoplatform (C‐MLip@LA) modulates tumor redox homeostasis to enhance targeted therapy. By encapsulating L‐arginine, anchoring MnO2 nanoparticles, and leveraging homologous membrane‐mediated specificity, C‐MLip@LA efficiently triggers a synergistic ROS/RNS cascade, amplifies immunogenic cell death, and ...

SMILE: Extraction‐free submicron‐resolution mapping of lipid chain length and unsaturation by stimulated Raman imaging

VIEW, EarlyView.
In this work, we develop submicron‐resolution mapping of intracellular lipid elements (SMILE) as an extraction‐free vibrational spectroscopic imaging platform based on hyperspectral stimulated Raman scattering microscopy with a spectral analysis pipeline for pixel‐resolved lipid profiling.

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.

Shikimate pathway disruption in yeast induces metabolite self‐assembly into toxic aggregates

The FEBS Journal, EarlyView.
In Saccharomyces cerevisiae, shikimate pathway disruption induces toxic metabolite assemblies. Deleting ARO4 plus phenylalanine (Phe) feeding causes Phenylalanine accumulation, lowers ARO3 activity, and triggers amyloid‐like fibril formation. Deleting ARO3 plus tyrosine (Tyr) feeding leads to Tyrosine buildup and similar fibril assembly.

Anemia‐associated mutations disrupt the CDIN1‐Codanin1 complex in inherited congenital dyserythropoietic anemia I (CDA‐I) disease

The FEBS Journal, EarlyView.
Congenital dyserythropoietic anemia type I (CDA‐I) arises from mutations in Codanin1 and CDIN1. Using quantitative biophysical approaches, we show that disease‐associated mutations disrupt the CDIN1‐Codanin1 complex. Our findings provide critical insights into the molecular mechanism that links protein dysfunction to disturbing chromatin arrangement ...
