Aptamer fluorescence anisotropy sensors for adenosine triphosphate by comprehensive screening tetramethylrhodamine labeled nucleotides [PDF]

open access: yesBiosensors and Bioelectronics, 2015
We previously reported a fluorescence anisotropy (FA) approach for small molecules using tetramethylrhodamine (TMR) labeled aptamer. It relies on target-binding induced change of intramolecular interaction between TMR and guanine (G) base. TMR-labeling sites are crucial for this approach. Only terminal ends and thymine (T) bases could be tested for TMR

Predicting aptamer sequences that interact with target proteins using an aptamer-protein interaction classifier and a Monte Carlo tree search approach.

open access: yesPLoS ONE, 2021
Oligonucleotide-based aptamers, which have a three-dimensional structure with a single-stranded fragment, feature various characteristics with respect to size, toxicity, and permeability.

Design and clinical developments of aptamer-drug conjugates for targeted cancer therapy

open access: yesBiomaterials Research, 2021
Background Aptamer has been called “chemical antibody” which displays the specific affinity to target molecules compared to that of antibodies and possesses several therapeutic advantages over antibodies in terms of size, accessibility to synthesis, and ...

Aptamer-Assisted Delivery of Nucleotides with Tumor-Suppressing Properties for Targeted Cancer Therapies

open access: yesTrends in Medical Sciences, 2021
: Targeted cancer therapy is developing rapidly according to the fact that it has been demonstrated that this type of therapy can reduce various side effects and adverse events of the commonly available cancer treatment approaches such as chemotherapy and radiotherapy.

HIV-1 reverse transcriptase mutations that confer decreased in vitro susceptibility to anti-RT DNA aptamer RT1t49 confer cross resistance to other anti-RT aptamers but not to standard RT inhibitors [PDF]

open access: yes, 2005
RNA and DNA aptamers specific for HIV-1 reverse transcriptase (RT) can inhibit reverse transcription in vitro. RNA aptamers have been shown to potently block HIV-1 replication in culture.

Towards the selection of phosphorothioate aptamers [PDF]

open access: yesEuropean Journal of Biochemistry, 2000
The high affinity of a given nucleic acid for a protein ligand can be used to isolate specific inhibitors of enzymes involved in pathological situations. The latter property is the basis of the SELEX (systematic evolution of ligands by exponential enrichment) technique.

Kinetic analysis of an efficient DNA-dependent TNA polymerase. [PDF]

open access: yes, 2005
alpha-l-Threofuranosyl nucleoside triphosphates (tNTPs) are tetrafuranose nucleoside derivatives and potential progenitors of present-day beta-d-2'-deoxyribofuranosyl nucleoside triphosphates (dNTPs).
