Engineered Exosomal miR‐146a‐5p Reprograms BMSC Fate and Restores Mitochondrial Homeostasis in Glucocorticoid‐Induced Osteonecrosis of Femoral Head

Advanced Science, EarlyView.
Exosomal miR‐146a‐5p is identified as a pivotal regulator in steroid‐induced osteonecrosis. Its reduction activates NF‐κB signaling, compromises mitophagy, and disrupts mitochondrial bioenergetics, resulting in autophagic disequilibrium. Engineered exosomes delivering miR‐146a‐5p reinstate mitochondrial function, augment oxidative phosphorylation and ...

Astrocytic FDX1 Contributes to Copper Dyshomeostasis‐associated Synaptic Dysfunction in Depression and Is Modulated by Exercise

Advanced Science, EarlyView.
Chronic stress disrupts copper homeostasis and promotes copper accumulation in the prelimbic cortex, leading to astrocytic FDX1 upregulation. Elevated astrocytic FDX1 impairs calcium signaling, induces structural atrophy, and disrupts synaptic function, contributing to depressive‐like behaviors. Physical exercise reverses these alterations by restoring

De Novo Designed Minibinders Targeting the GDF15–GFRAL Axis Reverse Cancer Cachexia and Restore Anti‐Tumor Immunity

Advanced Science, EarlyView.
Tumor‐derived GDF15 drives cancer cachexia and suppresses antitumor immunity. Here, de novo designed minibinders targeting the GDF15–GFRAL interface achieve picomolar affinity and potent pathway blockade. The minibinders alleviate cachexia, restore CD8+ T‐cell infiltration, enhance anti–PD‐1 responsiveness, and provide survival benefits across tumor ...

Ferritin Iron Mineralisation: Route of Fe3+ Transfer From the Ferroxidase Centre to the Inner Cavity of Human H‐Chain Ferritin

Angewandte Chemie, EarlyView.
Proposed mechanism for Fe3+ transport from the FoC (sites 1 and 2) of human H‐chain ferritin following oxidation of the di‐Fe2+ form. Glu61, aided by the flexibility of its sidechain, plays a key role in coordinating Fe3+ at three sites (3, 4 and 5) that mark out the transit route.

Ovarian Cancer Diagnosis and Chemoresistance Prediction Model Based on cfRNA Molecular Signature

Advanced Science, EarlyView.
A deep learning model analyzes cfRNA profiles extracted from the blood of OVCA patients. This innovative approach distinguishes OVCA from healthy controls with high accuracy. Crucially, it reliably predicts patient response to chemotherapy (sensitive versus resistant subgroups).

Metabolic Labeling and Visualization of Isoprenoids Using Alkyne‐Modified DMAPP Analogs in Bacillus subtilis

Angewandte Chemie, EarlyView.
Fluorescence‐based visualization and targeted mass–spectrometric enrichment of membrane‐embedded isoprenoids in Bacillus subtilis via cell‐permeant, alkynylated DMAPP analogs. ABSTRACT Isoprenoids are a chemically and functionally diverse class of metabolites that underlie essential bacterial physiology including respiration and cell envelope ...

Matrix Stiffness Induces Endothelial Network Senescence

Advanced Science, EarlyView.
Using a 3D human in vitro model that decouples mechanical stress from inflammatory or biochemical signals, matrix stiffening induces a senescence phenotype in endothelial networks. This mechano‐induced senescence activates Notch signaling, and pharmacologic Notch inhibition attenuates this stiffness‐induced senescence.

ROS‐Targeted Nanomotor Therapy in OA: Cartilage Protection and Pain Relief

Advanced Science, EarlyView.
ROS‐responsive NM@MET nanomotors utilize elevated ROS in osteoarthritic joints to promote deep penetration into cartilage and synovium and enable sustained metformin release. By scavenging ROS, regulating NRF2/KEAP1 signaling, protecting chondrocytes, suppressing synovial inflammation, and attenuating nociceptive signaling, NM@MET alleviates pain and ...

Harmonizing Rigidity and Flexibility: Embedding COF Quantum Dots Into Extracellular Matrix Gel as Carbon Monoxide Depot for Acoustically Triggered Time‐Programmable Anti‐Infective Therapy

Advanced Science, EarlyView.
A rigid‑flexible integrated CO depot is engineered by embedding rigid COFQDs into a flexible ECM gel network. The rigid framework enables high‑capacity CO storage and sonodynamic bacterial killing, while the flexible ECM gel controls sustained CO release, collectively eradicating multidrug‑resistant infection and promoting scarless healing.
