Nuclear Pore Mechanotransduction in Oncology: A Structural Axis of Vulnerability for Targeted Intervention

Advanced Materials, EarlyView.
Cancer‐associated NPC remodeling creates a high‐flux, low‐stringency nuclear state that supports malignant adaptation but increases mechanical fragility. Targeting the FG‐barrier or NPC scaffold may drive mechanostat failure, envelope rupture, DNA damage, and loss of nuclear integrity.

Redefining the Minimal Editable Unit of Supramolecular Synthons: A 1→2 Lattice-Editing Strategy in Ternary Multicomponent Crystals. [PDF]

Adv Sci (Weinh)
Inspired by skeletal editing, we propose a lattice‐editing strategy that extends the minimal editable unit in supramolecular crystals from individual components to local supramolecular structural units, enabling non‐stoichiometric one‐to‐many substitution while preserving the parent lattice architecture.
