Antiadhesive effects of GRN163L--an oligonucleotide N3'->P5' thio-phosphoramidate targeting telomerase.
We determined previously that a novel human telomerase RNA (hTR) antagonist, GRN163L, inhibited the tumorigenic potential of A549-luciferase (A549-luc) lung cancer cells in vitro and in vivo. Further studies revealed that A549-luc cells were also morphologically altered by GRN163L. A549-luc cells treated before cell attachment with a single dose of GRN163L only weakly attached to the substrate ...
متن کاملSynthesis of N3′-P5′-linked Phosphoramidate DNA by Nonenzymatic Template-Directed Primer Extension
A fast and accurate pathway for nonenzymatic RNA replication would simplify models for the emergence of the RNA world from the prebiotic chemistry of the early earth. However, numerous difficulties stand in the way of an experimental demonstration of effective nonenzymatic RNA replication. To gain insight into the necessary properties of potentially self-replicating informational polymers, we h...
متن کاملIdentification of a Novel CLCNKB Mutation in an Iranian Family with Bartter Syndrome Type 3.
Bartter syndrome (BS) is a group of uncommon genetic disorders of reabsorption of salt in the cortical thick ascending limb (TAL) of the Henle's loop, typically distinguished by metabolic alkalosis, salt loss, hypokalemia, hyperreninemic hyperaldosteronism and normal blood pressure. Bartter syndrome type 3, recognized as a classic BS (CBS), occurs because of mutations in CLCNKB gene. We enroll...
متن کاملAn improved synthesis and preliminary biodistribution study of a Technetium-99m-labeled 2-amino-2-deoxy(thioacetyl)-D-glucose complex ([99mTc]-TA-DG) as a tumor imaging agent
Introduction: This report describes the synthesis of 2-Amino-2-deoxy(S-benzoylthioacetyl)-D-glucose (S-Bz-TA-DG), radiolabeled with [99mTc(CO)3(OH2)3]+ complex with a procedure including deprotection of the benzoyl group, characterization by HPLC using a C18 reverse phase column and preliminary biodistribution study in normal ...
متن کاملAn Electrochemical Study of the S-Derivatives of 2-Amino Cyclopentene-1-Dithiocharboxylic Acid in Aqueous Ethanolic Media
A systematic study on the electrochemical behavior of the S-derivatives of 2-amino cyclopentene-1-dithiocarboxylic acid (ACDA) has been carried out in aqueous ethanolic solutions by means of polarography, coulometry and voltammetry. All the compounds studied exhibited a well defined anodic wave corresponding to a diffusion controlled process. Controlled potential coulometry gave n=1 per mol...
