RONIN/HCF1‐TFEB Axis Protects Against D‐Galactose‐Induced Cochlear Hair Cell Senescence Through Autophagy Activation

open access: yesAdvanced Science, EarlyView.
D‐galactose (D‐gal) induced inner ear hair cell senescence by inhibiting TFEB transcription. RONIN/HCF1 promotes TFEB transcription to prevent cochlear HCs from D‐gal‐induced senescence through autophagy activation. Abstract Age‐related hearing loss is characterized by senescent inner ear hair cells (HCs) and reduced autophagy.

Piezoelectric Biomaterials for Bone Regeneration: Roadmap from Dipole to Osteogenesis

open access: yesAdvanced Science, EarlyView.
Piezoelectric biomaterials convert mechanical forces into electrical signals, offering novel strategies to restore and modulate bone microenvironments for tissue engineering. This review examines molecular dipole origins, spatial arrangements, and pseudo‐piezoelectric mechanisms and highlights dipole‐engineering techniques for osteogenesis regulation ...

Identifying Myeloid‐Derived Suppressor Cells and Lipocalin‐2 as Therapeutic Targets for Intervertebral Disc Degeneration

open access: yesAdvanced Science, EarlyView.
Inflammatory dysregulation drives intervertebral disc degeneration via stage‐dependent immune cellular dynamics. Single‐cell transcriptomics and genetic risk mapping revealed a shift from LCN2high myeloid‐derived suppressor cells maintaining disc repair in early stages to IL1B+ macrophage‐dominated pathology in advanced disease.
