Intratumoral Hypoxia Triggers Mitochondrial BHLHE40 ROS Sensing Pathway to Promote Radioresistance in Triple‐Negative Breast Cancer

Advanced Science, EarlyView.
Hypoxia triggers a dual mechanism for BHLHE40 upregulation: reactive oxygen species (ROS)‐dependent post‐translational modification and hypoxia‐inducible factor (HIF)‐dependent transcriptional activation. Under hypoxic conditions, mitochondrial BHLHE40 accumulates and senses ROS via cysteine thiol oxidation and disulfide‐linked homodimer formation ...

Bending‐Stable Pressure Sensor Based on Natural Wood Nanofibers for Ultra‐Low Detection Limit

Advanced Science, EarlyView.
A wood nanofiber‐based flexible pressure sensor with intrinsic bending‐stable performance is developed through a porous electrospun architecture and interdigital electrode design. The device exhibits an ultra‐low detection limit and stable operation under deformation for physiological monitoring and spatial sensing, providing a sustainable strategy for

Differential Tissue‐Coupled Powering for Battery‐Free Injectable Electroceuticals

Advanced Science, EarlyView.
A thread‐like injectable neural stimulator is powered through differential tissue‐coupled powering (DTCP), which harvests RF‐frequency tissue potentials with an elongated receiver while preserving a injectable cross‐section. The system integrates an ASIC, stimulation electrodes, and a portable transmitter, enabling wireless peripheral nerve stimulation,

Mepce Restrains Ferroptosis in Prostate Cancer Through 7SK–P‐TEFb Pause Control

Advanced Science, EarlyView.
Genome‐wide CRISPR screening identifies MEPCE as a pause‐control regulator that restrains ferroptosis in prostate cancer. MEPCE loss releases P‐TEFb/CDK9 from 7SK snRNP control, enhances RNAPII Ser2 phosphorylation, and accelerates NRF2‐HMOX1‐driven labile iron accumulation and lipid peroxidation, revealing a transcriptional kinetic gate that lowers ...

Lanthanum Carbonate Nanosheets Based Colloidal Hydrogel for Modulating Innate & Adaptive Tumor Immunotherapy by Augmented Cellular Pyroptosis

Advanced Science, EarlyView.
The Gela/decitabine/La2(CO3)3 colloidal (GDLC) hydrogel developed here could reverse the epigenetic silencing of the GSDME gene by the synergistic interaction between DAC and La3+, while concurrently activating caspase‐3, thus facilitating pyroptosis induction under the tumor microenvironment.

A pH‐Switchable Cerium Single‐Atom Enzyme for Peri‐Implantitis Therapy via JAK‐STAT Signaling Axis‐Mediated Macrophage Reprogramming

Advanced Science, EarlyView.
A pH‐switchable cerium single‐atom enzyme is developed for stage‐specific peri‐implantitis therapy. Acidic conditions trigger antibacterial peroxidase‐like activity, whereas neutral conditions activate an antioxidant superoxide dismutase ‐ and catalase ‐like enzymatic relay. This microenvironment‐adaptive catalytic strategy suppresses the IL‐6/JAK‐STAT
