Idiosyncrasies of thermofluorimetric aptamer binding assays
BioTechniques, 2019 To explore thermofluorimetric analysis (TFA) in detail, we compared two related aptamers. The first, LINN2, is a DNA aptamer previously selected against EGFR recombinant protein. In this work we selected a second aptamer, KM4, against EGFR-overexpressing

Targeted Molecular Imaging Using Aptamers in Cancer
Pharmaceuticals, 2018 Imaging is not only seeing, but also believing. For targeted imaging modalities, nucleic acid aptamers have features such as superior recognition of structural epitopes and quick uptake in target cells. This explains the emergence of an evolved new class

cDC1 Subtype‐Specific In Vivo Targeting of Liposomes
Advanced Science, EarlyView.Dendritic cells, particularly the cDC1 subtype, offer a promising target for drug delivery via liposomes due to their pivotal role in immune regulation, allowing for amplified therapeutic responses. Herein, we show an integration of physicochemical characterization and cell experiments to achieve effective in vivo cDC1 targeting through anti‐CLEC9A ...

Advanced Science, EarlyView.The spatiotemporal dynamics of protein kinase diffusion govern cellular signaling and functions. Although vital for active receptors, the role of pseudokinase dynamics is unclear. Here, we use single‐molecule tracking to link faster diffusion of pseudokinase PTK7 to increased tumor cell invasion and migration.

Advanced Science, EarlyView.A Stringent dUPlex‐activated Error Robust (SUPER) DNAzyme system enables real‐time imaging of alternative mRNA splicing (e.g., Bcl‐xL/Bcl‐xS) in living cells via target‐triggered split‐DNAzyme reassembly and dual‐color fluorescence. It also achieves mRNA‐selective knockdown through DNAzyme‐based gene regulation, serving as a versatile tool for splicing

Dynamic Decoration of DNA Scaffolds for High‐Resolution Cancer Cell Subtyping
Advanced Science, EarlyView.This study presents a dual‐mode imaging platform that utilizes self‐assembly and disassembly of DNA scaffolds for high‐resolution cancer cell detection. The structural rigidity of DNA scaffolds effectively prevents cellular internalization for over 300 min.

Advanced Science, EarlyView.Telomerase reverse transcriptase (TERT) mRNA induces DNA self‐assembly in cancer cells, boosting the nanoplatform's magnetothermal properties. This magnetothermia then activates the Hsp70 promoter, initiating siRNA synthesis to silence the TERT gene, enhancing cancer treatment.
