PIAS3 CircRNA‐Loaded Lipid Nanoparticles Restore ALOX15 SUMOylation to Suppress Cementoblast Ferroptosis and Attenuate Orthodontically Induced Root Resorption

open access: yesAdvanced Science, EarlyView.
Orthodontic compression suppresses PIAS3 expression in cementoblasts, impairing ALOX15 SUMOylation and ubiquitin‐mediated degradation, which leads to ALOX15 accumulation, lipid peroxidation, ferroptosis, and osteoclastogenesis. Local delivery of PIAS3 circRNA‐loaded lipid nanoparticles restores the PIAS3–ALOX15 regulatory pathway, alleviates ...

NDFIP2 Suppresses Colorectal Cancer Metastasis Through DDX3X‐Dependent R‐Loop Remodeling and GNG13 Transcriptional Activation

open access: yesAdvanced Science, EarlyView.
NDFIP2 recruits NEDD4 to promote K48‐linked ubiquitination and proteasomal degradation of DDX3X, leading to R‐loop accumulation and CTCF‐dependent suppression of GNG13 transcription. Consequently, PI3K/AKT signaling, EMT, stemness, and colorectal cancer metastasis are inhibited.

Development‐Informed Microsphere Assemblies Enable Spatiotemporally Programmed Bone–Vascular Organoid‐Like Constructs for Large Bone Defect Repair

open access: yesAdvanced Science, EarlyView.
Single‐cell‐guided prioritization of BMP4 and VEGFA is combined with temporally programmed BMSCs and a Matrigel‐free GelMA/PEO/bioactive‐glass assembled‐microsphere matrix to generate bone–vascular organoid‐like constructs. The platform coordinates osteogenic differentiation, endothelial activation, vascular‐like microchannel formation, and ...

A Citrulline‐Functionalized Patch Coordinates Macrophage NRF2 Signaling and Arginine Metabolism for Tendon‐to‐Bone Repair

open access: yesAdvanced Science, EarlyView.
A locally implanted patch combines citrulline‐functionalized carbon dots, a thioketal‐containing membrane coating from tendon‐derived stem cells, and aligned core–shell fibers. In macrophages, the patch reduces inflammatory markers and enhances antioxidant signaling through nuclear factor erythroid 2‐related factor 2 (NRF2); in rats and rabbits, it ...

Microenvironment‐Responsive Biomimetic Hydrogels Delivering Cistanche Deserticola‐Derived Nanovesicles for Intervertebral Disc Degeneration

open access: yesAdvanced Science, EarlyView.
An injectable, microenvironment‐responsive hydrogel (HAPOCS@CDNVs) is developed for sustained delivery of Cistanche deserticola‐derived nanovesicles (CDNVs). By scavenging ROS, restoring mitochondrial function, and attenuating SASP, this platform effectively suppresses nucleus pulposus cell senescence and facilitates extracellular matrix reconstruction,

Pharmacokinetic Tuning Redirects β‐Lapachone From NQO1 Bioactivation to Vimentin‐Targeted Oxidation in Cancer

open access: yesAdvanced Science, EarlyView.
Pharmacokinetic tuning acts as a programmable mechanistic switch for β‐lap. Sustained low‐concentration exposure redirects β‐lap from NQO1 bioactivation to direct oxidation of vimentin, driving disulfide crosslinking, proteasomal overload and ferroptosis.

Targeting a Calcium‐Associated Mitochondrial Vulnerability in TET2‐Deficient Myeloid Cells

open access: yesAdvanced Science, EarlyView.
Reduced TET2 function creates a calcium‐associated mitochondrial vulnerability in macrophages that is preferentially exploited by Lanatoside C. The resulting stress promotes apoptosis of TET2‐deficient macrophages, reduces inflammatory and fibrotic injury in human cardiac organoids, and highlights a genotype‐associated myeloid liability that may be ...
