Dual-Mechanism Aptamer–Drug Complex Overcomes Paclitaxel Resistance in Ovarian Cancer via Structural Constraint and Telomerase Inhibition

open access: yesResearch
Paclitaxel resistance and poor tumor selectivity remain significant challenges in epithelial ovarian cancer therapy. To overcome these challenges, we engineered PSaA360, a structurally constrained aptamer–drug conjugate with a dual-functional molecular ...

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.

Introduction of a Double‐Headed Nucleotide Into G‐Quadruplex DNA: Position‐Dependent Stabilization and Structural Insights

open access: yesChemistry – A European Journal, EarlyView.
A double‐headed bis‐guanine (G) nucleotide (GG) was evaluated as a noncanonical building block in G‐quadruplexes (G4s). Biophysical and computational analyses reveal that GG can directly participate in G‐tetrads and strongly stabilize G4s in a position‐ and topology‐dependent manner. These findings establish design rules for using GG to engineer highly

Nanomedicine applications in lymphoma: Advancing precision diagnostics, targeted therapeutics, and prospective developments

open access: yesVIEW, EarlyView.
Lymphoma is a group of blood cancers that can appear in lymph nodes, blood, bone marrow, spleen, liver, or the central nervous system, which makes drug delivery and disease monitoring difficult. This review summarizes how nanomedicine technologies may improve targeted treatment and imaging, while carefully separating approved or guideline‐supported ...

Plasma Membrane Nucleolin Is a Receptor for the Anticancer Aptamer AS1411 in MV4-11 Leukemia Cells [PDF]

open access: yesMolecular Pharmacology, 2009
AS1411 is a DNA aptamer that is in phase II clinical trials for relapsed or refractory acute myeloid leukemia and for renal cell carcinoma. AS1411 binds to nucleolin, a protein that is overexpressed in the cytoplasm and on the plasma membrane of some tumor cells compared with normal cells.
