Fluorescent Polymer-AS1411-Aptamer Probe for dSTORM Super-Resolution Imaging of Endogenous Nucleolin

open access: yesBiomacromolecules, 2022
Nucleolin is a multifunctional protein involved in essential biological processes. To precisely localize it and unravel its different roles in cells, fluorescence imaging is a powerful tool, especially super-resolution techniques. Here, we developed polymer-aptamer probes, both small and bright, adapted to direct stochastic optical reconstruction ...

Nucleolin-Targeting AS1411 Aptamer-Conjugated Nanospheres for Targeted Treatment of Glioblastoma

open access: yesPharmaceutics
Post-operative chemotherapy is still required for the treatment of glioblastoma (GBM), for which nanocarrier-based drug delivery has been identified as one of the most effective methods. However, the blood-brain barrier (BBB) and non-specific delivery to non-tumor tissues can significantly limit drug accumulation in tumor tissues and cause damage to ...

Investigation of Interaction of Bismarck Brown Y- Palladium Complex with AS1411 G-quadruplex Aptamer

open access: yesTurkish Journal of Analytical Chemistry, 2022
Artan metabolik aktivite ve metastaz, kanser hücrelerinin ana ve en bilinen özellikleridir. Hücrelerin artan aktivitesi, G-dörtlü yapıların oluşumunda artışa neden olur. G-quadruplex'in çeşitli ligandlarla stabilizasyonu veya destabilizasyonu, hücre proliferasyonunda bozulmalara neden olabilir.
