A Dynamic Gate Enables Regioselective Hydroxylation of Free Arginine by a Non‐Canonical Heme Enzyme

open access: yesAdvanced Science, EarlyView.
The YqcI/YcgG enzyme AglA employs a unique “sandwich” fold and a dynamic gating mechanism to selectively hydroxylate AMPn‐Arg at Nε. Site‐directed mutations reprogram regioselectivity or enable activity on free arginine by altering hydrogen‐bond networks, precisely positioning substrates.

Overcoming EGFR‐Mediated Dendritic Cell Dysfunction to Enhance Anti‐tumor Immunity in EGFR‐Mutant NSCLC by Precisely Targeting CD73 With pH‐responsive Nanocarriers

open access: yesAdvanced Science, EarlyView.
EGFR mutations drive ERK/c‐Jun–mediated transcriptional activation of CD73, elevating adenosine levels and fostering an immunosuppressive TME by impairing DC maturation and CD8⁺ T cell priming. The pH‐responsive nanodrug F127ZIF‐8AB680 selectively inhibits CD73, normalizes adenosine metabolism, and re‐establishes effective anti‐tumor immunity ...

Surface‐Associated Proteins on Extracellular Vesicles Remodel the Tumor Microenvironment by Potentiating TGF‐β Signaling in a Contact‐Dependent Manner

open access: yesAdvanced Science, EarlyView.
Extracellular vesicles (EVs) released from TGF‐β‐activated CAFs are enriched with ECM proteins such as TSG6 and THBS1, which facilitate their binding to recipient cell membranes. This EV–cell interaction promotes the clustering of CD44 and TGF‐β receptors on the target cell surface, thereby potentiating TGF‐β signaling activity. This study highlights a

Cancer Stem Cells Shift Metabolite Acetyl‐Coenzyme A to Abrogate the Differentiation of CD103+ T Cells

open access: yesAdvanced Science, EarlyView.
Lei et al. demonstrate that cancer stem cells (CSCs) play a pivotal role in impairing the differentiation of CD103+ T cells in patients with non‐small‐cell lung cancer. The key mechanism involves CSC‐derived acetyl‐CoA, which disrupts CD103+ T cell differentiation by sequentially inducing acetylation and ubiquitination of the Blimp‐1 protein. Targeting
