Rapid Microfluidic Drug Sensitivity Testing Within 5 Days Using Minimal Clinical Tumor Samples
Advanced Science, EarlyView.This study develops the air‐punched fabrication approach for nanoliter‐scale microcavity arrays with ultra‐smooth microcavity surfaces, with which rapid formation and 3D culture of tumor cell spheroids from small numbers of cell samples, as well as high‐throughput drug sensitivity testing can be achieved within 5 days.

Nasal Mucosa‐Derived Extracellular Vesicles as a Systemic Antiaging Intervention
Advanced Science, EarlyView.This study shows that nasal mucosa‐derived extracellular vesicles (nmEVs) exert systemic anti‐ageing effects in mice by restoring circadian rhythm, suppressing cellular senescence, and improving cognitive function. In aged human bone marrow mesenchymal stem cells, nmEVs reverse senescence‐associated phenotypes and reactivate core clock gene expression.

Advanced Science, EarlyView.This study identifies the transcription factor ETV1 as a key driver of CD4⁺ T cell‐mediated intestinal inflammation in inflammatory bowel disease (IBD). ETV1 promotes CD4⁺ T cell activation, proliferation, and Th17 differentiation by activating the amino acid transporter SLC7A5, fueling metabolic reprogramming.

Advanced Science, EarlyView.This study identifies a smoking‐induced mechanism in LSCC whereby nicotine activates the CHRNA5–JAK2/STAT3 axis to drive STC2 transcription. STC2 upregulates TGFBI, which interacts with endothelial ITGA5 to regulate vascular permeability and promote metastasis.
