چکیده
We herein report the real-time observation of G-quadruplex formation by monitoring the G-quadruplex-induced global change of two duplexes incorporated in a DNA nanoscaffold. The introduced G-rich strands formed an interstrand (3 + 1) G-quadruplex structure in the presence of K(+), and the formed four-stranded structure was disrupted by removal of K(+). These conformational changes were visualized in a nanoscaffold in real-time with fast-scanning atomic force microscopy.

Construction of a junction DNA nanostructure and modulation of the junction switching to quadruplexes
A junction DNA nanostructure has been successfully built in lithium acetate buffer solution at a near-neutral pH value through the connection of two slipped junction structures that are formed by G-rich and C-rich strands. The GC-rich duplex junctions in the nanostructure can be switched to G-quadruplexes and i-motifs in weakly acidic potassium acetate solution, which leads to the assembly of D...
متن کاملIn silico screening of G-Quadruplex Structures in Wilms tumor 1 Gene Promoter
Introduction: X-ray diffraction studies have revealed that guanines in a DNA stands may be arranged in quartet and form a structure called G-quadruplexs. Bioinformatics studies suggested the formation of G-quadruplex structure in human crucial genes, including Wilms tumor 1 (WT1). The aim of this study was to in silico analysis of the guanine-rich sequence in the promoter region of the WT1 gene...
متن کاملK(+)-Responsive off-to-on switching of hammerhead ribozyme through dual G-quadruplex formation requiring no heating and cooling treatment.
Functional RNAs that switch their activities in response to K(+) may sense the intracellular (100 mM) and extracellular (5 mM) K(+) concentrations and regulate their functions accordingly. Previously, we developed a quadruplex hammerhead ribozyme (QHR) whose conformational change, from a duplex to a G-quadruplex, triggered by K(+) results in expression of the activity. However, this QHR require...
متن کاملIon-dependent conformational switching by a DNA aptamer that induces remyelination in a mouse model of multiple sclerosis
We recently reported that a guanosine-rich 40-mer DNA aptamer (LJM-3064) mediates remyelination in the Theiler's murine encephalomyelitis virus mouse model of multiple sclerosis. Here, we characterize the G-quadruplex forms of this aptamer in vitro, and demonstrate using circular dichroism spectroscopy that LJM-3064 undergoes a monovalent ion-dependent conformational switch. In the presence of ...
متن کاملEquilibrious Strand Exchange Promoted by DNA Conformational Switching
Most of DNA strand exchange reactions in vitro are based on toehold strategy which is generally nonequilibrium, and intracellular strand exchange mediated by proteins shows little sequence specificity. Herein, a new strand exchange promoted by equilibrious DNA conformational switching is verified. Duplexes containing c-myc sequence which is potentially converted into G-quadruplex are designed i...
