A glycolysis‐driven epigenetic switch promotes therapy resistance in meningioma. Increased lactate production enhances histone H3K27 lactylation, which activates PROS1 secretion. Secreted PROS1 engages TYRO3 signaling to degrade the senescence regulator CARF, allowing cancer cells to escape growth arrest.

An acid‐responsive core‐shell microneedle system normalizes the degenerative annulus fibrosus microenvironment by consuming pathological H+, generating O2, and providing NIR‐amplified redox buffering. Mechanistically, it epigenetically suppresses ferroptosis via DNMT3A‐dependent methylation of the ATF3 promoter, relieving ATF3‐mediated repression of ...

Interface‐Enhanced Electrochemical Epoxidation Over a Core‐Shell Nanozeolite TS‐1@Mn‐N‐C Catalyst
Core–shell interface of TS‐1@Mn‐N‐C enables in situ generation of high‐concentration H2O2 and its spatially confined activation toward epoxidation‐active η‐Ti‐OOH species, leading to highly efficient and continuous electrochemical epoxidation. The work successfully addresses the key challenge of inefficient mass transfer and slow kinetics caused by ...

Cannabinoid CB1 Receptor in Nociceptors Mediates Postoperative Analgesia via ASIC3 Inhibition
CB1R and ASIC3 are co‐expressed in CGRP+ nociceptors of mouse DRG. Plantar incision triggers an upregulation of ASIC3 and activation of ASIC3+ neurons, driving mechanical allodynia. CB1R activation suppresses ASIC3 function and downstream ERK1/2 phosphorylation, thereby braking nociceptive signaling and accelerating pain resolution.

PCSK9 upregulation in cerebrovascular endothelial cells and microglia destabilizes the Aβ transporter LRP1, while TRIB3‐associated autophagy blockade further limits intracellular Aβ degradation. A RAP‐modified tea‐polyphenol nanoparticle co‐delivers siPCSK9 and siTRIB3 to restore LRP1‐mediated Aβ efflux and autophagy‐dependent degradation, reducing Aβ ...
