A Cascaded DNA Nanocircuit for Multi‐Signal‐Responsive Precision siRNA Delivery in Cancer Therapy

open access: yesAdvanced Science, EarlyView.
A cascaded dual‐AND logic DNA nanocircuit is engineered to respond to three tumor‐specific signals in a sequential manner: extracellular acidic pH, membrane‐overexpressed nucleolin (NCL), and intracellular glutathione (GSH). This programmable system selectively releases siPARP1 in glioblastoma (GBM), effectively silencing PARP1 and reversing TMZ ...

Phosphorylated lipid-conjugated oligonucleotide selectively anchors on cell membranes with high alkaline phosphatase expression

open access: yesNature Communications, 2019
Membrane-anchored DNA probes have been used to study molecular interactions and control cell assembly, but are not selective for different cell membranes. Here the authors develop a lipid-conjugated oligonucleotide for alkaline phosphatase-dependent cell

Aptamer-Based K+ Sensor: Process of Aptamer Transforming into G‑Quadruplex

open access: yes, 2016
G-rich aptamers have been widely applied to develop various sensors for detecting proteins, small molecules, and cations, which is based on the target-induced conformational transfer from single strand to G-quadruplex.

Multi‐Technique Integration Identifies O‐GlcNAc Transferase in Fibroblast‐Like Synoviocytes as a Therapeutic Target for Rheumatoid Arthritis

open access: yesAdvanced Science, EarlyView.
AI‑guided single‑cell transcriptomics identifies OGT as a key regulator enriched in rheumatoid arthritis fibroblast‑like synoviocytes (RA‐FLSs). Inflammatory stimuli activate the OGT–SAP130 axis, which modulates the H3K27ac/H3K27me3 balance and epigenetically silences BTG2, promoting aggressive transformation of RA‑FLSs.

DNA origami-enhanced binding of aptamers to Staphylococcus aureus cells

open access: yesBiosensors and Bioelectronics: X
The combination of DNA origami nanostructures and aptamers provides a powerful technology for diagnostic assays. Here, we functionalized a DNA origami nanostructure with a Protein-A binding aptamer to target Staphylococcus aureus bacterial cells.

A State‐Gated Metallo‐DNAzyme Framework Programs Tumor Stress Vulnerability Through Metabolic Licensing

open access: yesAdvanced Science, EarlyView.
A tumor‐state‐gated metallo‐DNAzyme framework integrates miR‐21/APE1‐responsive GLUT1 silencing with Ca/Cu‐partitioned metal–nucleic acid assembly and cystine loading. The framework first weakens glucose‐dependent metabolic buffering and then amplifies copper‐ and disulfide‐associated stress, converting tumor metabolic adaptation into programmable ...

Expanding the DNA Nanotechnology Toolbox: Hierarchical Assembly and Self‐Sorting of DNA Tiles With Precisely Controlled Hydrophobic Behavior

open access: yesAngewandte Chemie, EarlyView.
DNA tile amphiphiles encode dual chemical information, directing nanostructure formation through base‐pairing and hydrophobic effects. Thermal annealing programs hierarchical assembly, with first‐formed interactions biasing the final morphology: short hydrophobic chain strands form DX‐tiles and then into stars, while long‐chain strands form SNAs and ...
