Solvation Effects on Hole Mobility in the Poly G/Poly C Duplex

open access: yes, 2012
Theoretical calculations of solvation contribution to hole energy in a polynucleotide chain give very low hole mobility values at zero temperature, \mu < 10^{-3} cm^2/(V s).

Force-induced misfolding in RNA [PDF]

open access: yes, 2009
RNA folding is a kinetic process governed by the competition of a large number of structures stabilized by the transient formation of base pairs that may induce complex folding pathways and the formation of misfolded structures. Despite of its importance

Targeting DAP5 Disrupts Alternate Mode of Translational Initiation in Tregs and Potentiates Antitumor Immunity

open access: yesAdvanced Science, EarlyView.
Regulatory T cells (Tregs) suppress antitumor immunity. This study identifies that the translation scaffold DAP5/eIF4G2 is upregulated in tumor‐infiltrating Tregs (ti‐Tregs). DAP5 mediates an alternate translation mode to sustain CD25 and MCL‐1 expression, which is critical for ti‐Treg stability and survival in the tumor microenvironment.

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

open access: yes, 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

5‐Methylcytosine Analysis of miRNAs in Minimal Change Disease

open access: yesBiotechnology and Applied Biochemistry, EarlyView.
ABSTRACT Minimal change disease (MCD) is a glomerular disorder, which is the most common cause of nephrotic syndrome in children. Additionally, the prevalence of MCD in adults has been increasing in recent years. During protein synthesis, noncoding RNAs can be regulated through a variety of modifications, which helps preserve biological diversity and ...

Polynucleotide Phosphorylase Mediates a New Mechanism of Persister Formation in Escherichia coli

open access: yesMicrobiology Spectrum, 2023
Despite the identification of many genes and pathways involved in the persistence phenomenon in bacteria, the mechanisms of persistence are not well understood.

Electronic signature of DNA nucleotides via transverse transport

open access: yes, 2004
We report theoretical studies of charge transport in single-stranded DNA in the direction perpendicular to the backbone axis. We find that, if the electrodes which sandwich the DNA have the appropriate spatial width, each nucleotide carries a unique ...

A Raman spectroscopic study of the interaction between nucleotides and the DNA binding protein gp32 of bacteriophage T4 [PDF]

open access: yes, 1987
Raman spectra of the bacteriophage T4 denaturing protein gp32, its complex with the polynucleotides poly(rA), poly(dA), poly(dT), poly(rU), and poly(rC), and with the oligonucleotides (dA)8 and (dA)2, were recorded and interpreted.

Biologically‐oriented alveolar ridge preservation to correct bone dehiscence at immediate implant placement

open access: yesClinical Advances in Periodontics, EarlyView.
Abstract Background The purpose of the present case study is to describe the application of a modification of the Biologically‐oriented Alveolar Ridge Preservation (BARP) principles in cases of peri‐implant bone dehiscence (PIBD) due to a compromised alveolus at immediate implant placement (IIP).

Evolved DNAzymes and Stable Activation Chemistry Enable High‐Efficiency DNA Ligation

open access: yesChemistry – A European Journal, EarlyView.
In vitro selection of pre‐structured DNA libraries and chemical screening of alternative activation groups yielded trans‐acting DNAzymes with faster ligation rates and enhanced DNA substrate stability. The combination of C3S1 DNAzymes and phosphobenzimidazole‐activated DNA substrates provides improved DNA ligation performance, offering promise for ...
