Ammonia Detoxification Inhibits Liver Metastasis by Reshaping Hepatic Microenvironment

open access: yesAdvanced Science, EarlyView.
Liver metastasis diverts aspartate into hyperactive pyrimidine synthesis, disrupting urea cycling and causing pathogenic ammonia accumulation. Ammonia dually reprograms the microenvironment by: (1) activating hepatic stellate cells (HSCs) into pro‐fibrotic metastasis‐associated fibroblasts (MAFs), and (2) suppressing anti‐tumor monocytes/macrophages ...

Carboranyl‐Curcuminoids for the Neutron Capture‐Based Treatment of Amyloid Aggregates in Alzheimer's Disease

open access: yesAdvanced Science, EarlyView.
The 10B‐enriched monocarbonyl analog of curcumin (BMAC) 10B‐9 enables site‐specific Boron Neutron Capture Therapy (BNCT) on amyloid‐β (Aβ) fibrils. Neutron irradiation induces histidine oxidation and fibril destabilization, as revealed by 1H‐NMR and FESEM analyses.

Kinesin‐Induced Buckling Reveals the Limits of Microtubule Self‐Repair

open access: yesAdvanced Science, EarlyView.
This study shows that kinesin‐driven buckling induces extensive microtubule lattice damage that often exceeds intrinsic self‐repair and leads to filament failure. While curvature, motor motility, and force individually cause limited damage, their combination overwhelms repair.

Artesunate Ameliorates APAP‐induced Liver Injury by Promoting NEDD4L‐Mediated Ubiquitination and Degradation of TXNIP

open access: yesAdvanced Science, EarlyView.
ABSTRACT Liver injury can lead to severe acute liver failure and even death in patients. Artesunate (ART), which is a derivative of artemisinin that has been approved by the FDA for the treatment of malaria, has significant regulatory effects on cell death and inflammation.

Beyond Extracellular Vesicle (EV) Hype: Practical Solutions and Remaining Hurdles in EV Research, Manufacturing, and Clinical Translation

open access: yesAdvanced Science, EarlyView.
ABSTRACT Extracellular vesicles (EVs) are nanoscale mediators of intercellular communication with diverse molecular cargoes that reflect their cell of origin. Advances in isolation, detection, and single‐particle analytics have revealed increasing molecular and functional heterogeneity, while exposing limitations in how EV identity and activity are ...
