Topological Quantum Biomaterials Enable Pyroptosis‐Senescence Coupling for Enhanced Colorectal Cancer Therapy

Advanced Science, EarlyView.
This work reports conceptually unprecedented topological quantum biomaterials derived from engineered Pd3Sn nanostrips for oncological applications. Their near‐Fermi‐level electronic architecture and superior interfacial charge transport facilitate ultrasound‐amplified redox reactions and efficient ROS generation.

Innovative Approach Reveals How Receptors Control G Protein State Equilibria

Advanced Science, EarlyView.
Using conformational specific trFRET biosensors of the Gi protein (depicted at the bottom), the authors show that receptor activation can not only release GDP from the inactive G protein, but can also release GTP from the activated G protein, leading to the reformation of the RG ternary complex.

An ATP7A‐Mediated Endogenous Regulation Bio‐Clay Enzyme Enables Self‐Amplified Copper Accumulation for Immunogenic Pyrop

Advanced Science, EarlyView.
A self‐amplifying bio‐clay nanozyme (Bio‐Clayzyme) disrupts tumor metabolic homeostasis through endogenous copper transporter ATPase (ATP7A) downregulation, enhancing cascade catalysis and triggering immunogenic pyroptosis for effective tumor immunotherapy.

Single‐Cell Transcriptomic Profiling Identifies B Cell‐Intrinsic Dysregulation of Sphingolipid Biosynthesis and Could Be Improved by Inhibiting UGCG in Primary Immune Thrombocytopenia

Advanced Science, EarlyView.
This study generates the single‐cell atlas of pathogenic B‐cell subset Bc‐5 in ITP. It identifies RUNX3 as a key survival regulator and uncovers sphingolipid‐driven metabolic reprogramming, validating UGCG inhibition as a therapeutic candidate and building a valuable resource for ITP mechanistic and therapeutic exploration.

Magnetoreceptor Promotes Hepatocellular Carcinoma Development and Blunts Sorafenib‐Induced Ferroptosis by Regulating Iron Homeostasis

Advanced Science, EarlyView.
Magnetoreceptor (MagR) regulates iron homeostasis and mitochondrial function in hepatocellular carcinoma (HCC) cells. Specifically, MagR deficiency suppresses tumor cell proliferation, migration, and invasion and enhances sorafenib‐induced ferroptosis through iron accumulation.

A Spatiotemporal Single‐Cell Atlas Uncovers Dysregulated ECM Dynamics and Septal Remodeling Arrest in Human Ventricular Septal Defects

Advanced Science, EarlyView.
Integrating single‐cell and spatial transcriptomics reveals human ventricular septal defect (VSD) as a disease of microenvironmental insufficiency and structural remodeling arrest. Attenuated endothelial‐fibroblast crosstalk, alongside downregulated THBS1/TGF‐β1 and MMP2 signaling networks, impairs the endothelial‐to‐mesenchymal transition (EndoMT) and

Adenosine A1 receptor-mediated antiadrenergic effects are modulated by A2a receptor activation in rat heart

, 2008
Presently, the physiological significance of myocardial adenosine A2a receptor stimulation is unclear. In this study, the influence of adenosine A2a receptor activation on A1 receptor-mediated antiadrenergic actions was studied using constant-flow ...
