Extracellular Vesicle‐Packaged Linc‐ZNF25‐1 from Pancreatic Cancer Cell Promotes Pancreatic Stellate Cell Uptake of Asparagine to Advance Chemoresistance

open access: yesAdvanced Science, EarlyView.
This study explores the role of gemcitabine (GEM)‐resistant pancreatic cancer‐derived extracellular vesicles (EVs) in activating pancreatic stellate cells (PSCs) and promoting extracellular matrix production. GEM‐resistant cells release higher levels of asparagine (Asn), which triggers PSC activation. Long noncoding RNA sequencing identified linc‐ZNF25‐

Cryo‐EM Analysis of a Tri‐Heme Cytochrome‐Associated RC‐LH1 Complex from the Marine Photoheterotrophic Bacterium Dinoroseobacter Shibae

open access: yesAdvanced Science, EarlyView.
Cryo‐EM reveals a closed 17‐subunit LH ring encircling the RC‐LH1 complex in Dinoroseobacter shibae, featuring a novel helix‐turn‐helix subunit bridging RC and LH. Mg2⁺/Ca2⁺ stabilizes the complex, while periplasmic Cyt c₂ mediates electron transfer via a tri‐heme Cyt to the special pair of bacteriochlorophylls. Insights into energy/electron efficiency

Tumor Microenvironment On‐A‐Chip and Single‐Cell Analysis Reveal Synergistic Stromal–Immune Crosstalk on Breast Cancer Progression

open access: yesAdvanced Science, EarlyView.
Using a 3D tumor microenvironment (TME)‐on‐a‐chip model, tumor–stromal–immune crosstalk in triple‐negative breast cancer is studied, revealing the TME's combinatorial effect on cancer progression. Integrating single‐cell transcriptomic analysis demonstrates metabolic reprogramming via the kynurenine pathway, highlighting the complex TME cellular ...
