Chemoenzymatic Radiosynthesis of a Gluconate Transporter‐Targeted In Vivo Bacterial Sensor From Clinical [18F]FDG

Angewandte Chemie, EarlyView.
An efficient radiosynthesis of fluorine‐18 labeled gluconic acid ([18F]FGA) was developed using two readily available materials, 2‐deoxy‐2‐[18F]fluoro‐D‐glucose ([18F]FDG) and glucose oxidase. [18F]FGA is highly specific for bacterial gluconate metabolism mediated by gluconate permease (GntP) and gluconate kinase (GntK), with rapid clearance, low off ...

Dependence of bioavailability of folic acid and (6S)-5-methyltetrahydrofolate on baseline red blood cell folate concentrations in infants

Human Nutrition & Metabolism
Background: Folate bioavailability may depend on folate status of an individual and the form of folate presents in foods. Objective: We studied whether changes of red blood cell (RBC)-folate concentrations following dietary intervention with folic acid ...

MiR‐940 Suppresses Ferroptosis by Controlling Expression of Key Regulatory Genes

Advanced Science, EarlyView.
A CRISPR‐based screening identified miR‐940 as a critical suppressor of ferroptosis in cancer. By coordinating the downregulation of pro‐ferroptotic genes with the upregulation of GPX4, miR‐940 establishes a regulatory network that protects against ferroptosis and correlates with poor clinical outcomes in distinct cancer entities.

An Integrated DNA Nanoprobe for Intranuclear Imaging and in Situ Profiling of OGG1 Activity

Advanced Science, EarlyView.
The TP‐SA nanoprobe, integrating an AS1411 aptamer for nuclear delivery and a FRET array for signal amplification, enables real‐time tracking of nuclear OGG1 activity. It reveals cell‐line‐specific basal OGG1 levels and shows clinical promise using pneumonia patients’ lavage fluid.

Identification of a Nonribosomal Peptide Analog With Activity Against Multiple Gram‐Positive Bacteria via a Synthetic Bioinformatic Natural Product Discovery Approach

Advanced Science, EarlyView.
The genome of Rhodococcus erythropolis D‐1 was analyzed by bioinformatic tools to mine a novel nonribosomal peptide synthetase (NRPS) gene cluster. A nonribosomal peptide analog ZURJC5 associated with the NRPS was chemically synthesized. Through structure‐activity relationship studies, ZURJC28 was ultimately obtained and showed antibacterial activity ...

Engineered Au@CeO2 Hybrid Nanoparticles With Microenvironment Dependent Self‐Adjustability for Integration of Tumor‐Specific Photothermal‐Chemodynamic Therapy and Inflammation Prevention

Advanced Science, EarlyView.
An intelligent Au@CeO2 Hybrid Nanoparticles (ACEF) with microenvironment‐dependent self‐adjustability was engineered to not only perform efficient and tumor‐specific photothermal‐chemodynamic therapy for precise tumor elimination, but also serve as a ROS scavenger in healthy tissues around the tumor to avoid the unexpected oxidative damage and ...

A Single‐Amino‐Acid Ligand for LAT1: A Minimalist and Modular Platform for Lysosome‐Targeted Degradation of Membrane Proteins

Advanced Science, EarlyView.
LA‐LYTAC repurposes the cancer‐enriched amino acid transporter LAT1 as a lysosomal trafficking receptor for targeted membrane‐protein degradation. A single phenylalanine‐derived ligand, modularly linked to antibodies or small‐molecule binders, recruits PD‐L1, EGFR, or integrins to LAT1, triggering transporter‐mediated internalization, lysosomal ...
