Pulling hairpinned polynucleotide chains: Does base-pair stacking interaction matter?

, 2001
Force-induced structural transitions both in relatively random and in designed single-stranded DNA (ssDNA) chains are studied theoretically. At high salt conditions, ssDNA forms compacted hairpin patterns stabilized by base-pairing and base-pair stacking

Base Orientation of Second DNA in RecA·DNA Filaments. Analysis by combination of linear dichroism and small angle neutron scattering in flow-oriented solution [PDF]

, 1998
To gain insight into the mechanism of pairing two complementary DNA strands by the RecA protein, we have determined the nucleobase orientation of the first and the second bound DNA strands in the RecA·DNA filament by combined measurements of linear ...

Ablation of keratan sulfate accelerates early phase pathogenesis of ALS. [PDF]

PLoS ONE, 2013
Biopolymers consist of three major classes, i.e., polynucleotides (DNA, RNA), polypeptides (proteins) and polysaccharides (sugar chains). It is widely accepted that polynucleotides and polypeptides play fundamental roles in the pathogenesis of ...

Translocation of structured polynucleotides through nanopores

, 2004
We investigate theoretically the translocation of structured RNA/DNA molecules through narrow pores which allow single but not double strands to pass. The unzipping of basepaired regions within the molecules presents significant kinetic barriers for the ...

CRISPRa Lipid Nanocomplex‐Mediated Mt3 Targeting Enhances Astrocytic Endocytosis of Amyloid‐β in an Alzheimer's Disease Mouse Model

Advanced Science, EarlyView.
GeTe exhibits intrinsically high carrier concentrations that limit its thermoelectric performance. Herein, CuAgSe alloying synergistically tunes the band structure, induces band flattening and valence‐band convergence, promotes Cu‐ion delocalization, and generates multiscale hierarchical structures to suppress phonon transport.

Sequence specific binding of beta carboline alkaloid harmalol with deoxyribonucleotides: binding heterogeneity, conformational, thermodynamic and cytotoxic aspects. [PDF]

PLoS ONE, 2014
Base dependent binding of the cytotoxic alkaloid harmalol to four synthetic polynucleotides, poly(dA).poly(dT), poly(dA-dT).poly(dA-dT), poly(dG).poly(dC) and poly(dG-dC).poly(dG-dC) was examined by various photophysical and calorimetric studies, and ...
