Temperature Thresholds Govern Microbial‐Mediated Dissolved Organic Carbon Dynamics in Coastal Ecosystems

Advanced Science, EarlyView.
Coastal dissolved organic carbon (DOC) represents one of the largest reduced carbon pools on Earth, and they are influenced by temperature. Across 7.6–35.9 °C ranges, the microbial‐mediated DOC dynamics is characterized by three temperature thresholds.

Dual‐Terminal Molecular Strategy for Robust and Reversible Supramolecular Adhesion

Advanced Science, EarlyView.
A minimalist supramolecular adhesive derived from a dual‐terminal molecule bearing carboxylic acid and triphenylphosphonium groups achieves strong, reversible adhesion through synergistic noncovalent interactions. The system exhibits rapid curing, broad substrate compatibility, and exceptional stability under solvents, humidity, and extreme ...

Novel Role of Gut‐Derived Roseburia Intestinalis in Safeguarding Intestinal Barrier Integrity and Microenvironment Homeostasis During Arsenic Exposure

Advanced Science, EarlyView.
Arsenic exposure disrupts intestinal barriers and gut microenvironment. Fecal microbiota transplantation (FMT) alleviates arsenic‐induced damage, with gut‐derived Roseburia intestinalis (R.i) identified as a key protective strain. R.i administration counters arsenic toxicity through immunomodulatory pathways and metabolites.

Activation of USP30 Disrupts Endothelial Cell Function and Aggravates Acute Lung Injury Through Regulating the S‐Adenosylmethionine Cycle

Advanced Science, EarlyView.
USP30 deubiquitinates and stabilizes MAT2A, thereby regulating DNA methylation and miRNA expression, which ultimately leads to disruption of lung endothelial barrier and inflammation. Abstract Microvascular dysfunction is a key contributor to the development of acute inflammatory diseases, characterized by heightened vascular hyperpermeability and ...

ARL5B Drives Esophageal Squamous Cell Carcinoma Progression via ROCK1–SREBP1‐Mediated Lipid Metabolic Reprogramming

Advanced Science, EarlyView.
Esophageal squamous cell carcinoma urgently requires new therapeutic strategies. Adenosine diphosphate‐ribosylation factor‐like protein 5B (ARL5B) is identified as a novel oncogene that remodels fatty acid metabolism through the ras homologous‐associated coiled‐coil containing protein kinase 1 (ROCK1)–sterol regulatory element‐binding protein 1 (SREBP1)
