A Multi‐Targeting Chimeric Antigen Receptor‐T Cell Platform to Overcome Antigen Heterogeneity in the Treatment of Non‐Small Cell Lung Cancer

Advanced Science, EarlyView.
A dual‐transmembrane Bicephali CAR‐T platform simultaneously targets CD276 and NKG2D ligands to address antigen heterogeneity in non‐small cell lung cancer. By improving immune synapse formation, mitochondrial fitness, antioxidant capacity, and stem‐like persistence, this design enhances durable tumor control and provides a versatile strategy to ...

POE Immunoassay: Plate-based oligonucleotide electro-chemiluminescent immunoassay for the quantification of nucleic acids in biological matrices

Scientific Reports, 2020
Oligonucleotide therapeutics use short interfering RNA (siRNA) or antisense oligonucleotide (ASO) molecules to exploit endogenous systems—neutralizing target RNA to prevent subsequent protein translation. While the potential clinical application is vast,

Metabolic Signatures for Liver Cancer Diagnosis and Mechanistic Insights: A Large‐Scale, Multicenter Study

Advanced Science, EarlyView.
A large‐scale multicenter serum metabolomics study (13 centers, n = 2,149) identified a 9‐metabolite + AFP diagnostic signature for liver cancer (AUC = 0.93). Among the signature, nicotinamide (NAM) was validated as an oncometabolite: NAM enhances NAD+ synthesis, activating SIRT1 to deacetylate and stabilize HIF1α, thereby driving glycolysis, MAPK ...

An Engineered Supramolecular Pathway for Enhanced Electrochemiluminescence

Advanced Science, EarlyView.
A supramolecular electrochemiluminescent (ECL) system is presented in which cucurbit[7]uril (CB7) is covalently linked to [Ru(bpy)3]2+, forming a recognition‐responsive emitter. Host‒guest preorganization of tri‐n‐propylamine enables intramolecular ECL, boosting intensity by 162% compared to the standard system.
