Surfaceome Reprogramming of Stemsomes Promotes Lung Cancer Targeting via Potentiated Receptor–Ligand Interactions

Advanced Science, EarlyView.
This study presents a surfaceome‐reprogramming strategy for mutation‐independent lung cancer therapy by repurposing dexamethasone to prime mesenchymal stem cell‐derived nanovesicles. The engineered vesicles leverage multi‐valent interactions mediated by upregulated adhesion proteins, EPHA2, and NOTCH3.

Bioluminescence resonance energy transfer to detect protein-protein interactions in live cells. [PDF]

Methods Mol Biol, 2015
Bioluminescence resonance energy transfer (BRET) is a valuable tool to detect protein-protein interactions. BRET utilizes bioluminescent and fluorescent protein tags with compatible emission and excitation properties, making it possible to examine resonance energy transfer when the tags are in close proximity (

Single‐Cell Profiling Identifies SLC2A5‐Mediated Fructose Metabolism as a Vulnerability in Primary CNS Lymphoma

Advanced Science, EarlyView.
Glucose deprivation in the primary CNS lymphoma (PCNSL) tumor microenvironment drives SLC2A5 (encoding GLUT5)‐dependent fructose metabolism in tumor cells, while hypoxia induces HIF‐mediated SLC2A5 expression in tumor‐supportive macrophages, revealing SLC2A5‐driven fructose utilization as a shared and targetable metabolic vulnerability across malignant

Engineering Synergistic Intra‐/Intermolecular Conformational Locking via Side‐Chain Branching: A β‐Sheet‐Inspired Strategy for Planar NIR‐II Phototheranostic Aggregates

Advanced Science, EarlyView.
A bio‐inspired side‐chain branching strategy is developed to orchestrate a dual noncovalent conformational locking (NoCL) network, enabling the construction of perfectly planar NIR‐II phototheranostic aggregates. Such structural precision maximizes light‐harvesting efficiency and optimizes exciton dynamics, ensuring synchronized enhancements in NIR‐II ...

Protocol for measuring BRAF autoinhibition in live cells using a proximity-based NanoBRET assay

STAR Protocols, 2023
Summary: BRAF is frequently activated via mutation in human cancer and the RASopathy syndromes; however, for BRAF activation to occur, autoinhibitory interactions between the regulatory and catalytic domains must be relieved. Here, we present a proximity-
