MUC15 Ectodomain Architecture Regulates Integrin Clustering to Control Cancer Metastasis

open access: yesAdvanced Science, EarlyView.
This study uncovers a size‐dependent adhesion paradigm, demonstrating that the glycocalyx protein MUC15 suppresses pancreatic cancer progression by attenuating integrin activation, focal adhesion assembly, and YAP mechanotransduction. Integrating computational modeling and experimental validation, the work reveals a mechanical mechanism by which MUC15 ...

Transverse‐Electric Cherenkov Radiation for TeV‐Scale Particle Detection

open access: yesAdvanced Science, EarlyView.
Finite refractive indices of naturally existing materials place a fundamental ceiling on the momentum of detectable particles in traditional Cherenkov detectors. This work demonstrates transverse‐electric graphene plasmon Cherenkov radiation, breaking the momentum barrier for particle detection beyond the TeV scale with exceptional robustness and ...
