Microcystin‐LR Triggers Renal Tubular Ferroptosis Through Epigenetic Repression of GPX4: Implications for Environmental Nephrotoxicity

Advanced Science, EarlyView.
MC‐LR stabilizes DNMT1/3a by blocking their ubiquitin‐mediated degradation, leading to Gpx4 promoter hypermethylation and E2F4/NCoR‐associated transcriptional repression, which drives renal tubular ferroptosis in mice. Pharmacological inhibition of DNA methylation (SGI‐1027) or ferroptosis (Fer‐1) disrupts this DNMT‐GPX4 axis, thereby alleviating MC‐LR‐

Chloroplast Stress Signals Orchestrate Epidermis‐Specific Remodeling of Mitochondria and ER Under High Light

Advanced Science, EarlyView.
High light exposure triggers an epidermis‐specific remodeling of mitochondria and ER in Arabidopsis, driven by chloroplast‐derived signals. Live‐cell imaging shows that HL rapidly suppresses mitochondrial motility, followed by fusion‐driven elongation and ER cisternal expansion.

Hair dye poisoning and the developing world

Journal of Emergencies, Trauma and Shock, 2009
Hair dye poisoning has been emerging as one of the important causes of intentional self harm in the developing world. Hair dyes contain paraphenylene-diamine and a host of other chemicals that can cause rhabdomyolysis, laryngeal edema, severe metabolic ...

A Blood‐Brain Barrier‐Penetrant Ag(III) Corrole Compound Rescues Alzheimer's Disease Pathology by Targeting Aβ42‐Induced Oxidative Stress

Advanced Science, EarlyView.
The newly designed metallo‐corrole (Mor‐Cor)Ag(III) with a morpholino group exhibited promising therapeutic potential for Alzheimer's disease. It significantly reduces reactive oxygen species (ROS), decreases GFAP expression, increases neurite length, and decreases cell death compared to other similar metallo‐corroles. Abstract Alzheimer's disease (AD)

USP35 Acts as a Deubiquitinating Enzyme for ID3 to Promote Immune Escape in Colorectal Cancer

Advanced Science, EarlyView.
USP35 stabilizes ID3 expression by deubiquitinating the K2/K30 site, thereby upregulating PD‐L1 and promoting immune escape in colorectal cancer. IU1, an inhibitor of USP35 enzyme activity, has been shown to inhibit USP35, thereby accelerating ID3 degradation, enhancing CD8+ T cell killing, and reversing the immunosuppressive microenvironment ...

Iron/Cobalt Dual‐Atom Catalyst Orchestrate Photothermal‐Chemodynamic Immunotherapy Against MRSA: Multi‐Omics Dissection in Murine and Porcine Models

Advanced Science, EarlyView.
FeCo dual‐atom catalyst (FeCo‐N‐DAC) with ultrahigh metal loading (Fe > 5.4%, Co > 4.8%) is developed for synergistic photothermal‐chemodynamic immunotherapy. FeCo‐N‐DAC penetrates deep‐seated tissues, eradicates MRSA biofilms, and reprograms immune‐inflammatory pathways via multi‐omics‐validated mechanisms.

Alphaviral Capsid Proteins Inhibit Stress Granule Assembly via Competitive RNA Binding With G3BP1

Advanced Science, EarlyView.
Stress granules exert antiviral functions. This study illustrates a conserved function of alphaviral capsid proteins in modulating stress granules. Oligomerization mediated by a helical motif coupled with a positively charged intrinsically disordered region (IDR) directly competes with G3BP1 for RNA binding, thereby disrupting G3BP1‐RNA liquid–liquid ...

A Glucose‐Responsive Intelligent Antibacterial and Oxygen‐Producing Hydrogel Promotes the Healing of Diabetic Wounds by Regulating Cellular Heterogeneity

Advanced Science, EarlyView.
We have developed a glucose‐triggered on‐demand drug delivery CF‐CPGaMPN hydrogel based on borate ester bonds. It inactivates microbes, releases oxygen, and enables on‐demand drug release in high‐glucose environments to promote healing of diabetic wounds. Single‐cell sequencing reveals that the CF‐CPGaMPN hydrogel significantly alleviates dysfunctional
