Gut Microbiota‐Isoallolithocholic Acid Crosstalk Promotes Calcium Oxalate Kidney Stone Formation via PARP1‐Mediated Parthanatos

Advanced Science, EarlyView.
ABSTRACT Bile acids have been implicated in calcium oxalate (CaOx) nephrolithiasis. Here, we employ multi‐omics approaches to identify isoallolithocholic acid (isoalloLCA) as the key bile acid elevated in the feces, serum, kidney, and urine of CaOx rats, confirmed by spatial metabolomics.

Structural Basis of Shiga Toxin Neutralization by Human Antibodies Targeting Canonical Receptor‐Binding and Non‐Canonical Assembly Sites

Advanced Science, EarlyView.
Cryo‐electron microscopy structures reveal two distinct neutralization mechanisms of fully human monoclonal antibodies targeting the Shiga toxin 1a B subunit. RDS059 occludes the Gb3 receptor‐binding site, whereas RDS045 engages a lateral quaternary epitope to disrupt holotoxin assembly.

Targeting the KAT7/H3K14ac/RAC2 Axis Mediates OXPHOS to Promote Stemness Maintenance and Malignancy in Glioblastoma

Advanced Science, EarlyView.
SOX2 upregulates KAT7 in glioma stem cells, where KAT7 deposits H3K14 acetylation at the RAC2 promoter to activate RAC2 transcription. RAC2‐GTP subsequently promotes PAK1/2/3 phosphorylation, increasing tricarboxylic acid cycle flux and mitochondrial respiration to support glioblastoma malignancy.

Spatiotemporal Thermal Modulation and Patterning using a Programmable 1024 Element Microheater Array

Advanced Science, EarlyView.
Programmable microheater arrays are essential for a variety of applications. However, large arrays have thus far not been realized. We introduce a programmable 32×$\times$32 microheater array consisting of heating elements – each smaller than 300 μm$\umu{\rm m}$.

Stabilizing Functional Nucleic Acids for Real‐Sample Diagnostics

Angewandte Chemie, EarlyView.
Functional nucleic acids enable programmable real‐sample diagnostics, but often lose function in complex biological matrices. This review highlights four stabilization levers—chemical, topological, architectural, and microenvironment/interface engineering—that preserve aptamer and DNAzyme performance in saliva, serum, urine, and stool, reframing ...

Sonogenetics Nanomedicine Activates the cGAS‐STING Pathway for Immunotherapy of Triple‐Negative Breast Cancer

Advanced Science, EarlyView.
A HER3‐targeted sonogenetic lipid nanoparticle platform is developed for triple‐negative breast cancer therapy. An AI‐designed miniprotein inhibits HER3 signaling, while TRPV4 and NFAT‐responsive IL‐15 plasmids enable ultrasound‐controlled calcium signaling and cytokine expression. The system induces Ca2+ overload, ROS generation, mitochondrial damage,
