WDR5‐H3K4me3 Epigenetic Axis Promotes TRMT6‐Dependent tRNA M1A Modification to Facilitate Triple‐Negative Breast Cancer Progression by Suppressing Ferroptosis

open access: yesAdvanced Science, EarlyView.
Upregulated TRMT6 forms aberrant hypermethylation of a specific tRNA pool and serves as a predictor of poor prognosis in TNBC. This m1A modification in tRNAs enhances translation of FTH1 and FTL, reducing the pool of bioavailable Fe2⁺. Reduced Fe2+ availability impairs RSL3‐induced lipid peroxidation and tumor progression.

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

Magnetically‐Induced Suppression of Oxidative Stress Prevents Venous Thrombosis

open access: yesAdvanced Science, EarlyView.
Venous thromboembolism (VTE) remains a leading cause of cardiovascular mortality. This study demonstrates that static magnetic fields (SMF) offer a novel non‐pharmacological intervention against VTE by mitigating endothelial oxidative stress. Mechanistically, SMF elevates intracellular Ca2+, boosts ATP production, and suppresses NOX4‐mediated ROS ...

Microfluidic Electrochemical Biosensor for the Detection of Platelet Factor 4 Antibody‐Mediated Thrombotic Disorders

open access: yesAdvanced Science, EarlyView.
A microfluidic electrochemical biosensor enables sensitive and specific detection of antibodies associated with vaccine‐induced immune thrombotic thrombocytopenia (VITT) and heparin‐induced thrombocytopenia (HIT). The platform uses two antigen targets— platelet factor 4 (PF4) and cross‐linked‐PF4 (c‐PF4)—and microliter volumes of patient sera to ...

A Modular Chemoenzymatic Cascade Simplifies Divergent Synthesis of Natural and Unnatural Benzylisoquinoline Alkaloids

open access: yesAdvanced Science, EarlyView.
A simplified chemoenzymatic platform is designed to integrate an enzyme cascade with subsequent chemical steps, enabling the divergent production of diverse benzylisoquinoline alkaloids (BIAs). Demonstrating remarkable versatility and enantioselectivity, four distinct classes of BIAs are efficiently generated, in which the natural medicine papaverine ...

Arid1a Deficiency Drives Aristolochic Acid‐Induced Liver Tumorigenesis through Ctnnb1 Mutation and Defective Nucleotide Excision Repair

open access: yesAdvanced Science, EarlyView.
ARID1A is frequently mutated in both non‐malignant tissues and cancers, but its role in tumor development after exposure to genotoxic carcinogen remains unclear. It is found that aristolochic acid I accelerated liver tumorigenesis in ARID1A‐deficient context by impairing nucleotide excision repair and enhancing carcinogen bioactivation, revealing key ...
