Single‐Cell Atlas of Subchondral Bone Marrow Lesions Reveals Proteostasis Dysfunction as a Druggable Mechanism for Early Osteoarthritis

Advanced Science, EarlyView.
This study reveals that abnormal mechanical stress downregulates the expression of HSP70 and impairs proteasome function in osteoarthritic bone cells, leading to misfolded collagen I accumulation and ER stress. When intracellular proteostasis capacity is exceeded, USP19 mediates the secretion of misfolded proteins into the extracellular space ...

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

All‐PEG‐Like Block Copolymers Self‐Assemble into Stealth Nanocarriers for Drug Delivery

Advanced Science, EarlyView.
Self‐assembling nanoparticles composed entirely of POEGMA are engineered by exploiting side‐chain–dependent amphiphilicity and tunable thermoresponsive behavior. These single‐material nanocarriers encapsulate diverse hydrophobic drugs with high efficiency, retain therapeutic activity, improve in vivo efficacy, and evade anti‐PEG antibodies.

Genome‐Wide Association Study Reveals Insect Genetics and Microbial Symbiont Effects on Susceptibility of Diaphorina citri to the Citrus Greening Pathogen, Candidatus Liberibacter Asiaticus

Advanced Science, EarlyView.
This study investigates the genetic and microbial factors influencing the susceptibility of Diaphorina citri to the citrus greening pathogen Candidatus Liberibacter asiaticus (CLas), employing a microbiome Genome Wide Association Study. The research identifies a key gene encoding an MFS‐type transporter contributing to CLas infectivity and abundance in

Injectable Chondroitin Sulfate Methacrylate Hydrogel Microspheres Co‐Loaded with GLPM Nanozyme, Dexamethasone, and Stem Cells for Synergistic Osteoarthritis Therapy

Advanced Science, EarlyView.
A multifunctional injectable microsphere system is fabricated via UV‐assisted microfluidic cross‐linking, integrating nanozyme‐based ROS scavenging, sustained dexamethasone release, and stem cell delivery. Upon IA injection, the microspheres adapt to joint stress, suppress inflammation, and promote cartilage regeneration, offering a minimally invasive ...

Ascites circRNA ASCOR Drives Platinum Resistance of High‐Grade Serous Ovarian Cancer by Facilitating RPA1 Nuclear Translocation

Advanced Science, EarlyView.
High‐grade serous ovarian carcinoma (HGSOC) is plagued by platinum resistance, with malignant ascites closely linked to poor outcomes. Here, we identify ASCOR, a circRNA enriched in ascites small extracellular vesicles (sEVs) from platinum‐resistant HGSOC patients, as a predictor of poor survival. ASCOR enhances platinum resistance in vitro and in vivo
