NSD2 Coordinates the Neurogenic‐to‐Gliogenic Transition via H3K36me2‐Dependent Activation of the EGFR‐ERK Pathway

open access: yesAdvanced Science, EarlyView.
NSD2 coordinates the neurogenic‐to‐gliogenic transition in the developing neocortex through H3K36me2‐dependent activation of EGFR–ERK signaling. Loss of NSD2 disrupts astroglial and oligodendroglial development, whereas ERK activation rescues gliogenic defects in vitro and in vivo.

Human Dental Pulp Stem Cell Secretome Restores Ischemic Stroke–Impaired Motor and Cognitive Functions by Reprogramming Redox and Inflammatory Signaling

open access: yesAdvanced Science, EarlyView.
Human dental pulp stem cell secretome emerges as a cell‐free therapeutic strategy for ischemic stroke by reprogramming redox and inflammatory signaling. hDPSC secretome‐derived antioxidant and immunomodulatory factors suppress the TLR4–NOX–ROS–NF‐κB axis, reduce microglial inflammatory responses and apoptosis, and promote neurogenesis, angiogenesis ...

O‐GlcNAcylation Regulation of SNAP29‐Dependent Autophagy Activation Dictates Chemoresistance in Gastric Cancer

open access: yesAdvanced Science, EarlyView.
Model illustrating the proposed mechanism by which chemotherapy‐induced downregulation of OGT disrupts SNAP29 O‐GlcNAcylation, promoting STX17‐SNAP29‐VAMP8 SNARE complex assembly and protective autophagy, leading to chemoresistance, which in turn establishes a feedforward loop to perpetuate drug tolerance.

Super‐Multiplexed Label‐Free Raman Imaging Uncovers Novel Testicular Metabolic Couplings for Residual Body and Spermatogonial Differentiation

open access: yesAdvanced Science, EarlyView.
Super‐multiplexed Label‐free Raman Imaging (SLRI) enables 2D/3D metabolic mapping of intact Drosophila testes. Moving beyond descriptive morphology, it establishes a multidimensional tool for tissue metabolic remodeling, and offers a generalizable platform for complex tissue analysis, with implications extending to development and disease.

Aberrant GRP78 Phase Transition Sustains Endothelial IRE1α Signaling and Drives Blood–Brain Barrier Failure in Cerebral Amyloid Angiopathy

open access: yesAdvanced Science, EarlyView.
Vascular Aβ40 corrupts GRP78 phase behavior in brain endothelial cells, sustaining IRE1α–TRAF2–JNK signaling and driving apoptosis, tight junction loss, and blood–brain barrier failure in cerebral amyloid angiopathy. Pharmacological IRE1α inhibition restores vascular integrity, reduces leakage, and improves functional outcomes, revealing a targetable ...

Engineering a 660 nm‐Responsive Optogenetic Inducer of Pyroptosis for Precision Cancer Therapy

open access: yesAdvanced Science, EarlyView.
This study reports a bioorthogonal pyroptosis inducer, PyroRACS. By using a red‐light‐responsive Cre‐On genetic switch to control the expression of highly cytotoxic GSDMDNT, PyroRACS enables the artificial induction of pyroptosis with precise spatiotemporal control.

A High‐Loading Zn Single‐Atom Nanozyme Targets the Zn/HIF‐1α/GLUT1 Axis to Disrupt Glucose Metabolic Reprogramming and Remodel the Tumor Immune Microenvironment

open access: yesAdvanced Science, EarlyView.
A high‐loading Zn single‐atom nanozyme (ZMG@CS) delivers ML‐SA5 and GOx to lysosomes. ML‐SA5 activates TRPML1 to release endogenous Zn2+, while the nanozyme provides exogenous Zn2+ and GOx‐driven acidification amplifies ROS production. Together, these effects suppress the HIF‐1α/GLUT1 axis, disrupt glucose and redox homeostasis, induce disulfidptosis ...

Chromatin Packing Domain Engineering Through the Manipulation of Nuclear Cationic States

open access: yesAdvanced Science, EarlyView.
Manipulation of intranuclear divalent cation concentrations rapidly and reversibly remodels chromatin packing domains in living cells. Magnesium depletion disrupts domain compaction, heterochromatin organization, and transcriptional regulation, whereas magnesium loading promotes more compact and stable domains.
