Structural and mechanistic insights into ribosomal ITS2 RNA processing by nuclease-kinase machinery

eLife
Precursor ribosomal RNA (pre-rRNA) processing is a key step in ribosome biosynthesis and involves numerous RNases. A HEPN (higher eukaryote and prokaryote nucleotide binding) nuclease Las1 and a polynucleotide kinase Grc3 assemble into a tetramerase ...

Phospholipid Remodeling and Tri‐Layer Membrane Reconstruction Mediate Cognitive Effects of Humanized Milk Fat Globules in Neonatal Rats

Advanced Science, EarlyView.
Humanized milk fat globules (MFG) mimic the native composition and structure of human milk, achieved through remodeling of milk fat globule membrane phospholipid composition and reconstruction of the tri‐layer membrane structure. These humanized MFG exhibit improved structural stability and digestibility, and enhance neurodevelopment in formula‐fed rat

Synergistic Promotion of Triple‐Negative Breast Cancer Tumorigenesis and Metastasis by Oral Polystyrene Nanoplastics Exposure via Alloprevotella‐Derived Glutamate and Platelet Activation

Advanced Science, EarlyView.
Polystyrene nanoplastics (PS‐NPs) administered via oral exposure accelerate triple‐negative breast cancer (TNBC) progression by synergistically modulating gut microbiota‐derived glutamate production and platelet activation. This study uncovers a pivotal crosstalk between microbial metabolites and platelet‐tumor interactions, offering mechanistic ...

Material‐to‐Application Integration: Rapid Fabrication of Field‐Deployable Hydrogel‐SiO2 DNA Separator for Low‐Resource Point‐of‐Care Diagnostics

Advanced Science, EarlyView.
A rapidly fabricated hydrogel‐SiO2 composite enables ultralow‐cost, equipment‐minimized DNA extraction, outperforming commercial kits. Hierarchical microstructures enhance hydrophobic/salt‐bridge‐driven adsorption. Integrated with visual LAMP, this field‐deployable system detects Vibrio parahaemolyticus at 10 CFU mL−1 in <40 min, offering ...
