Human telomeric DNA is typically 5–10 kb long duplex DNA consisting of tandem repeats of the motif d[TTAGGG] with a single-stranded 3’ overhang of 30–600 bases [].These G-rich single-stranded overhangs were already shown to form discrete G4 arrangements, being … WebDec 24, 2024 · The exosomes were captured by the HER2 aptamer region of MAB immobilized on the chip surface, which enabled the exposure of the G-quadruplex DNA (G4 DNA) that could form peroxidase-like G4-hemin. In turn, the formed G4-hemin catalyzed the deposition of plentiful tyramine-coated gold nanoparticles (AuNPs-Ty) on the exosome …
WebJul 9, 2024 · Abstract. G-quadruplexes (G4) are alternative nucleic acid structures involved in transcription, translation and replication. Aberrant G4 formation and stabilisation is linked to genome instability and cancer. G4 ligand treatment disrupts key biological processes leading to cell death.
