Electronic signature of DNA nucleotides via transverse transport
, 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 ...

Force-induced misfolding in RNA [PDF]
, 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

Insights Into Cockayne Syndrome Type B: What Underlies Its Pathogenesis?
Aging Cell, EarlyView.Cockayne Syndrome complementation group B (CS‐B) is a highly debilitating progeroid syndrome that often culminates in the death of patients before adulthood. This review explores the pathogenesis of CS‐B and proposes that a combination of DNA damage accumulation, transcriptional dysregulation, and mitochondrial dysfunction is its underlying cause ...

Derivatization of unprotected polynucleotides
Nucleic Acids Research, 1983 A simple and efficient method for attaching amines to the terminal 5'-phosphate of unprotected oligonucleotides or nucleic acids in aqueous solution is described. The method is applicable to low molecular-weight amines, polypeptides, or proteins. The terminal 5'-phosphate of an oligonucleotide or nucleic acid reacts with a water-soluble carbodiimide in

Polynucleotide phosphorylase has an impact on cell biology of Campylobacter jejuni
Frontiers in Cellular and Infection Microbiology, 2012 Polynucleotide phosphorylase, encoded by the pnp gene, is known to degrade mRNA, mediating post-transcriptional regulation and may affect cellular functions. The role of PNPase is pleiotropic.

Role of polynucleotide kinase/phosphatase in mitochondrial DNA repair
Nucleic Acids Research, 2011 Mutations in mitochondrial DNA (mtDNA) are implicated in a broad range of human diseases and in aging. Compared to nuclear DNA, mtDNA is more highly exposed to oxidative damage due to its proximity to the respiratory chain and the lack of protection ...

Adenovirus-mediated hPNPase(old-35) gene transfer as a therapeutic strategy for neuroblastoma [PDF]
, 2009 Current treatment options for neuroblastoma fail to eradicate the disease in the majority of high-risk patients, clearly mandating development of innovative therapeutic strategies. Gene therapy represents a promising approach for reversing the neoplastic

The FEBS Journal, EarlyView.When overexpressed in Staphylococcus aureus, the type I toxins SprA1 and SprA2 form membrane pores, with SprA1 creating stable pores and SprA2 forming transient ones. Both induce concomitant membrane depolarization, ATP release, and growth arrest, while only SprA1 causes membrane permeabilization due to its stable pore formation.

Synthesis and polymerization of 1-(2-diallylaminoethyl)pyrimidines
Designed Monomers and Polymers, 2018 We report the preparation and characterization of three pyrimidine-based monomers, specifically: 1-(2-diallylaminoethyl)uracil, 1-(2-diallylaminoethyl)thymine and 1-(2-diallylaminoethyl)cytosine.
