A Genetically Encoded Biosensor for Characterizing Transport and Metabolism of Glutarate

open access: yesAdvanced Science, EarlyView.
Here, a genetically encoded glutarate biosensor, Glusor, is developed based on transcriptional regulator CsiR. Glusor can quantify glutarate concentrations with good accuracy and precision. Then, the role of KgtP and YnfM are identified and characterized by using Glusor. Glusor also allows glutarate spatiotemporal resolution in live cells, facilitating

KLK1 as an Epithelial‐Specific Brake Inhibits Colorectal Tumorigenesis by Suppressing B1R‐Mediated Fibroblast Phenotypic Transition

open access: yesAdvanced Science, EarlyView.
KLK1 downregulation disrupts the intestinal mucosal barrier and impairs kallikrein‐kinin signaling, thereby reducing Lys‐des‐Arg9‐BK production. This enhances B1R activation on ADAMDEC1⁺ fibroblasts, promoting inflammation and extracellular matrix (ECM) remodeling. The resulting iCAFs promote colorectal cancer progression, highlighting a novel KLK1‐B1R

Engineered crRNA Drives RPA‐T7‐CRISPR/Cas14a Cascade for Ultrasensitive Detection of ctDNA PIK3CA H1047R

open access: yesAdvanced Science, EarlyView.
The TIDE‐Cas14a system, an integrated RPA‐T7‐CRISPR/Cas14a cascade platform incorporating engineered crRNA mismatches, enables ultrasensitive detection of the PIK3CA H1047R mutation in breast cancer circulating tumor DNA, with a limit of detection as low as 0.01%, surpassing the sensitivity of droplet digital PCR.

Dnmt1 Alleviates S1PR1‐Mediated Pyroptosis after Spinal Cord Injury through Regulating Pon3 Expression

open access: yesAdvanced Science, EarlyView.
This study systematically explores the action mechanism of Pon3 and its regulatory targets in spinal cord injury (SCI). It demonstrates that Dnmt1 regulates Pon3 expression by modulating methylation levels, thereby inhibiting S1PR1‐mediated pyroptosis and improving SCI prognosis.

Assessing Extracellular Vesicle Turnover In Vivo Using Highly Sensitive Phosphatidylserine‐Binding Reagents

open access: yesAdvanced Science, EarlyView.
Extracellular vesicles (EVs) are promising biomarkers, but their heterogeneity limits clinical use. A novel high‐affinity phosphatidylserine (PS)‐binding reagent is introduced that reveals ≈90% of circulating EVs are PS⁺. This enables in vivo tracking, showing rapid EV clearance and retention in spleen immune cells—advancing EV quantification ...
