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 ...

A Biomimetic Dual‐Targeting Nano‐APA‐Editor Reprograms the 3'UTR Landscape for Tongue Squamous Cell Carcinoma Therapy

Advanced Science, EarlyView.
This study unveils a pathogenic axis in oral cancer where NUDT21 suppresses a tumor suppressor network, prominently PTEN, via 3'UTR lengthening. To exploit this transcriptomic vulnerability, we developed a biomimetic Nano‐APA‐editor. By delivering CRISPR/Cas9, we reprogrammed the global 3'UTR landscape, restoring multi‐target tumor suppression and ...
