Extracellular Vesicle‐Mediated Nucleolin Transfer in Glioblastoma: A Targetable Axis Driving Blood‐Tumour Barrier Formation [PDF]
Journal of Extracellular VesiclesGlioblastoma (GBM) remains a significant therapeutic challenge. While GBM‐derived extracellular vesicles (EVs) are known to remodel the normal blood‐brain barrier (BBB) into a blood‐tumour barrier (BTB), the underlying mechanism is largely not understood.

Exploring the G-Quadruplex Formation of AS1411 Derivatives [PDF]
MoleculesAS1411 is a G-quadruplex (G4) aptamer that binds tightly to nucleolin (NCL) on the cell surface and has shown strong anticancer effects. However, this aptamer is highly polymorphic, presenting different types of G4s, which may hinder its preclinical ...

Locking up the AS1411 Aptamer with a Flanking Duplex: Towards an Improved Nucleolin-Targeting
Pharmaceuticals, 2021 We have designed AS1411-N6, a derivative of the nucleolin (NCL)-binding aptamer AS1411, by adding six nucleotides to the 5′-end that are complementary to nucleotides at the 3′-end forcing it into a stem-loop structure. We evaluated by several biophysical

Anti-nucleolin aptamer AS1411: an advancing therapeutic
Frontiers in Molecular Biosciences, 2023 Targeted therapy is highly desirable, as it allows for selective cytotoxicity on diseased cells without off-target side effects. Nucleolin is a remarkable target for cancer therapy given its high abundance, selective presence on the plasma membrane, and ...
