Anti-nucleolin aptamer mediated specific detection of cancer cells by Localized Surface Plasmon Resonance-based U-bent optical fiber

open access: yesBiosensors and Bioelectronics: X, 2023
The detection of Circulating Tumor Cells (CTCs) is of profound importance for cancer diagnosis and monitoring in diseased patients. In the presented work, an aptasensor for CTC detection was developed using AS1411 aptamer specific for nucleolin on cancer

A Modular DNAzyme for Precise Visualization and Intervention of Alternative Splicing Isoforms in Live Cells. [PDF]

open access: yesAdv Sci (Weinh)
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

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.
