Matrix Stiffness Orchestrates Mesenchymal Stem Cell Lineage Commitment Toward Osteogenesis and Adipogenesis Through the PIEZO1/SP1/STC2 Axis

open access: yesAdvanced Science, EarlyView.
Matrix stiffness directs mesenchymal stem cell lineage commitment through PIEZO1‐dependent activation of the SP1/STC2 pathway. Stiff matrices favor osteogenesis and suppress adipogenesis, whereas the loss of PIEZO1 function impairs early bone formation. STC2 retains lineage‐regulatory activity even when PIEZO1 is inactive.

Enteric ChAT‐Expressing Neurons Mediate the Protective Effect of Lactobacillus plantarum in Inflammatory Bowel Disease

open access: yesAdvanced Science, EarlyView.
In colitis patients and mice, reduced Lactobacillus abundance is observed. Experimental studies show that L. plantarum A736 metabolizes dietary tryptophan into indole‐3‐lactic acid (ILA), while both L. plantarum A736 and ILA impact ChAT‐expressing enteric neurons and acetylcholine levels, thereby regulating intestinal immune responses and alleviating ...

Chemotherapy‐Activated GSK3β‐DNMT1 Signaling Upregulates CD47 to Evade Macrophage Phagocytosis and Drive Temozolomide Resistance in Glioblastoma

open access: yesAdvanced Science, EarlyView.
Temozolomide treatment activates GSK3β, driving DNMT1 phosphorylation, destabilization, and CD47 promoter hypomethylation in glioblastoma. This epigenetic shift upregulates CD47, enabling TMZ‐treated GBM cells to evade macrophage phagocytosis, survive chemotherapy, and acquire resistance.

DLST Succinylation‐Mediated Mitochondrial Metabolic Remodeling and Cuproptosis Resistance Promote Malignant Progression of Lung Adenocarcinoma

open access: yesAdvanced Science, EarlyView.
The DLST K409 succinylation mediated by CPT1A promotes OXPHOS and redox homeostasis through regulating enzyme activity, thereby promoting the malignant progression of LUAD. Notably, the succinylation of DLST can enhance the cuproptosis resistance by inhibiting its lipoylation.

Transient Sleep Deprivation Induces Persistent Auditory Neuropathy via ROS‐Initiated Neuroinflammation and BK Channel Suppression

open access: yesAdvanced Science, EarlyView.
Sleep disturbance severity closely tracks hearing loss in a clinical cohort, yet the mechanistic link remains unclear. Acute sleep deprivation is shown to trigger transient cochlear oxidative stress that switches into a self‐sustaining neuroinflammatory state, suppressing BK channels and causing irreversible synaptopathy.

Phase Separation of SF3B1 Serves as a Critical Post‐Transcriptional Regulator During Early Mouse Embryogenesis

open access: yesAdvanced Science, EarlyView.
Phase separation of SF3B1 acts as a key regulatory mechanism for dynamic alternative splicing throughout early mouse embryogenesis. Its absence triggers extensive splicing errors, which induce persistent DNA damage, defective cell cycle progression, and failed cell lineage commitment, and ultimately hinder the normal growth and development of ...
