Microglial Membranes Wrapped Ultrasmall Medium‐Entropy Ru Single‐Atom Nanozyme: Enhanced Catalysis for Accelerating Inflammation/Redox Microenvironment Regulation in Intracerebral Hemorrhage

Advanced Science, EarlyView.
PtRhIr/Ru SAN@M nanozymes cross the blood–brain barrier and selectively accumulate in hemorrhagic brain regions. By mimicking multiple enzyme activities, they attenuate oxidative stress, modulate microglial polarization toward an anti‐inflammatory phenotype, inhibit ferroptosis, and promote neuronal repair.

Dual Aptamers‐Based SETDB1 PROTACs as Effective Anti‐Tumor Strategies for Breast Cancer

Advanced Science, EarlyView.
This study establishes dual‐aptamer PROTACs targeting SETDB1 using a SETDB1‐specific aptamer conjugated to AS1411. The designed PROTACs penetrate cells, recruit MDM2 to degrade SETDB1, and inhibit cancer cell proliferation and migration. Remarkably, they also overcome tamoxifen resistance and enhance CD8+ T cell cytotoxicity, suppressing tumor growth ...

Biomimetic Nanoplatform for Targeted Glioblastoma Therapy via Concurrently Triggering GPX4/DHODH Mediated Ferroptosis

Advanced Science, EarlyView.
Considering the great challenge in Glioblastoma multiforme (GBM) treatment, the authors designed and synthesized a multifunctional nanoplatform that effectively induced ferroptosis by synergetically inhibiting intrinsic intrisinc anti‐ferroptosis proteins, GPX4 & DHODH, and realized excellent in vitro and in vivo anti‐GBM effect.

A Mitochondria‐Specific Nanomedicine for Synergistic Chemo‐Photothermal Therapy and Immunogenic Activation Against Breast Cancer

Advanced Science, EarlyView.
Peptide dendrimer–based nanoplatform with mitochondria‐targeting capability was developed for synergistic chemo‐photothermal therapy. The system promotes efficient transcytosis, induces mitochondrial dysfunction, triggers immunogenic cell death (ICD), and enhance antitumor immunity by promoting dendritic cell maturation and T‐cell activation, resulting

Surface‐Bound Superoxide Radical‐Mediated Photo‐Fenton Mineralization of Ciprofloxacin on Fe‐Sillenite Nanosheets

Advanced Science, EarlyView.
This study systematically compares the degradation efficiency of CIP in a H2O2‐alone system and a novel Bi12FeO20‐H2O2 photo‐Fenton system. It reveals for the first time the presence of a quinone‐imine intermediate in the H2O2‐alone system, which exhibits toxicity comparable to CIP.

A LDH‐Based Supramolecular Photosensitizer‐Functionalized Bioactive Glass Scaffold for Integrated Postoperative Osteosarcoma Recurrence Prevention and Bone Regeneration

Advanced Science, EarlyView.
An intercalation assembly strategy is proposed to construct a novel LDH‐based supramolecular photosensitizer, which exhibits outstanding reactive oxygen species generation activity under 1270 nm laser irradiation. The deposition of supramolecular photosensitizer onto the surface of bioactive glass scaffolds results in the development of an innovative ...

Expanding the Phenotype of TUFM‐Related Combined Oxidative Phosphorylation Deficiency 4

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Combined oxidative phosphorylation deficiency 4 (COXPD4) is a rare mitochondrial condition caused by biallelic deleterious variants in the nuclear‐encoded gene TUFM. To date, most individuals with COXPD4 have presented with encephalopathy, hypotonia, and abnormal brain imaging. Many of the reported individuals died in infancy. We aim to expand

NUAK2 Inhibition Enhances Macromolecular Drug Delivery in a 3D Fibrotic Model of the Pancreatic Tumor Microenvironment

Advanced NanoBiomed Research, EarlyView.
Using a 3D cell culture model of the fibrotic barrier in pancreatic cancer, this work shows that inhibiting NUAK2 kinase in pancreatic stellate cells enhances macromolecular drug delivery. Mechanistically, NUAK2 inhibition disrupted actin stress fiber assembly to downregulate collagen I expression, thus enhancing macromolecular permeability.
