A Single‐Enzyme Activated CRISPR‐Cas12a Nano System via Subtly Balanced dsDNA for Kinetic‐Gated UDG Detection and Spatiotemporal Cellular Imaging

open access: yesAdvanced Science, EarlyView.
Kinetic‐gated CRISPR–Cas12a activation enables single‐enzyme detection and spatiotemporal imaging of UDG ABSTRACT Uracil‐DNA glycosylase (UDG) is a key enzyme in base excision repair and an important biomarker for genomic stability and disease. In many reported sensing systems, uracil excision is coupled to signal generation through additional ...

A Modular and Programmable Cas13d Platform for RNA Single Nucleotide Variant Detection

open access: yesAdvanced Science, EarlyView.
A scenario‐guided Cas13d platform enables configurable single nucleotide variant ribonucleic acid diagnostics through rule‐based guide design and ribonucleic acid binding domain engineering, supporting amplification‐free ultrasensitive detection and amplification‐coupled robust detection for accurate mutation classification in clinical tumor specimens.

Orthogonal Ionic Liquid‐Based Extraction Strategy Enables Amyloid‐Specific Profiling of Aggregate Proteome

open access: yesAdvanced Science, EarlyView.
An orthogonal ionic‐liquid extraction (Orth‐iEA) enables selective isolation of amyloid fibrils. TMGBF4 disrupts hydrogen‐bonded β‐sheet networks to solubilize amyloid aggregates, whereas C12ImCl interacts with hydrophobic regions of non‐amyloid proteins.

Microglia‐Targeted Biomimetic Tetrahedral Framework Nucleic Acid Nanovesicles for Synergistic Treatment of Sepsis‐Associated Encephalopathy

open access: yesAdvanced Science, EarlyView.
Sepsis‐associated encephalopathy (SAE) lacks effective therapies. We developed ME@FDsi, a biomimetic nanodrug using a tetrahedral framework nucleic acid to deliver disulfiram and siTNFα. It crosses the blood‐brain barrier, targets M1 microglia, inhibits pyroptosis and inflammation, and scavenges ROS.

G4‐Ligand‐Directed PROTACs Unveil DR1 as a Novel Ligand‐Co‐Binding G4‐Protein and Reshape G4‐Dependent Transcription

open access: yesAdvanced Science, EarlyView.
G4‐binding proteins (G4BPs) that specifically co‐bind G4s in the presence of small‐molecule ligands represent a critical but unexplored class of proteins. We introduce G4‐Ligand‐Directed PROTACs (G4L‐TACs), a chemical platform that couples G4 ligands (PDS) to E3 recruiters to selectively degrade these ligand‐co‐binding G4BPs.

CRISPR/Cas13a: Compensatory Target Activation Mechanism

open access: yesAdvanced Science, EarlyView.
CRISPR/Cas13a‐CTAM as a novel compensatory target activation mechanism that enables synergistic activation of Cas13a via two independently editable short RNA effectors. This dual‐effector system maintains enzymatic activity comparable to traditional single‐effector while significantly enhancing flexibility, sensitivity, and application scope.
