Sequence-dependent structural properties of B-DNA: what have we learned in 40 years?

John Maddocks, Daiva Petkeviciute, Rahul Sharma, Marco Pasi, Paolo Carloni

The structure of B-DNA, the physiological form of the DNA molecule, has been a central topic in biology, chemistry and physics. Far from uniform and rigid, the double helix was revealed as a flexible and structurally polymorphic molecule. Conformational ch ...

Dynamic Chromatin Invasion and Remodeling by the Transcription Factor Rap1

Maxime Nicolas Mivelaz

Pioneer transcription factors (PTF) are a subset of transcription factors with nucleosome-binding properties allowing them to bind specific sequences in condensed chromatin. Although the biological functions of PTFs including target genes and epigenetic ch ...

Site-Specific Protein Conjugation onto Fluorescent Single-Walled Carbon Nanotubes

Ardemis Anoush Boghossian, Shang-Jung Wu, Vitalijs Zubkovs, Nils Schürgers

Semiconducting single-walled carbon nanotubes (SWCNTs) are among the few photostable optical emitters that are ideal for sensing, imaging, drug delivery, and monitoring of protein activity. These applications often require strategies for immobilizing prote ...

Requirements for DNA bubble structure for efficient cleavage by helix-two-turn-helix DNA glycosylases

Kristina Makasheva

Oxidative DNA lesions, constantly generated by both endogenous and environmentally induced reactive oxygen species, are removed via the base excision repair pathway. In bacteria, Fpg and Nei DNA glycosylases, belonging to the helix-two-turn-helix (H2TH) st ...

The memristive effect as a novelty in drug monitoring

Giovanni De Micheli, Sandro Carrara, Ioulia Tzouvadaki, Nima Aliakbarinodehi

Nanoscale devices exhibiting memristive properties show great potential in a plethora of applications. In this work, memristive nanowires are presented for the first time as ideal candidates for absolutely novel, ultrasensitive, highly specific and selecti ...

Label-Free Ultrasensitive Memristive Aptasensor

Giovanni De Micheli, Sandro Carrara, Ioulia Tzouvadaki

We present the very first worldwide ever-reported electrochemical biosensor based on a memristive effect and DNA aptamers. This novel device is developed to propose a completely new approach in cancer diagnostics. In this study, an affinity-based technique ...

More DNA–Aptamers for Small Drugs: A Capture–SELEX Coupled with Surface Plasmon Resonance and High-Throughput Sequencing

Carlotta Guiducci, Fabio Mario Spiga

To address limitations in the production of DNA aptamers against small molecules, we introduce a DNA-based capture-SELEX (systematic evolution of ligands by exponential enrichment) protocol with long and continuous randomized library for more flexibility, ...

Label-free Analytics by Transmission Localized-SPR and its Application to Small Molecules Monitoring in Serum

Giulia Cappi

In the frame of therapeutic drug monitoring and personalized medicine, point-of-care systems (POCs) that can help overcome long waiting times for results and costly procedures of clinical tests are highly desirable. At present, the detection of low-molecul ...

Microfluidic assays for DNA manipulation based on a block copolymer immobilization strategy

Demetri Psaltis, Andreas Vasdekis

Methods to manipulate and visualize isolated DNA and oligonucleotide strands are important for investigation of their biophysics as well as their interactions with proteins. Herein, we report such a method by combining a block copolymer surface functionali ...

Metabolization of [Ru(η6-C6H5CF3)(pta)Cl2]: a cytotoxic RAPTA-type complex with a strongly electron withdrawing arene ligand

Paul Joseph Dyson, Anna Katherine Renfrew, Christian Hartinger

The anticancer ruthenium-arene compd. [Ru(η6-C6H5CF3)(pta)Cl2] (pta = 1,3,5-triaza-7-phosphatricyclo[3.3.1.1]decane), termed RAPTA-CF3, with the electron-withdrawing α,α,α-trifluorotoluene ligand, is one of the most cytotoxic RAPTA compds. known. To ration ...

Proteins as Possible Targets for Cytotoxic trans-Platinum(II) Complexes with Aliphatic Amine Ligands: Further Exceptions to the DNA Paradigm

Paul Joseph Dyson, Angela Casini, Michael Groessl

The reactivity of three cytotoxic trans-PtII complexes bearing aliph. amine ligands, with transferrin and single-stranded oligonucleotides as DNA models, was investigated by ESI-MS and the results obtained are discussed in comparison with cisplatin. Tandem ...

Comprehensive analysis of Arabidopsis expression polymorphisms with simple inheritance

Darlene Goldstein

In Arabidopsis thaliana, gene expression level polymorphisms (ELPs) between natural accessions that exhibit simple, single locus inheritance are promising quantitative trait locus (QTL) candidates to explain phenotypic variability. It is assumed that such ...

Kinetics of RNA Refolding in Dynamic Equilibrium by 1H-Detected 15N Exchange NMR Spectroscopy

Geoffrey Bodenhausen, Philipp Wenter

By implementing new NMR methods that were designed to map very slow exchange processes we have investigated and characterized the refolding kinetics of a thermodynamically stable 34mer RNA sequence in dynamic equilibrium. The RNA sequence was designed to u ...

Synthesis and evaluation of 2'-O-substituted oligoribonucleotide analogues with new properties

Luc Reymond

During a previous, exploratory project in our group, it was observed that duplexes formed by oligonucleotides modified with polar 2'-O-substituents were more tolerant towards the addition of 1,2-dimethoxyethane (DME) than RNA and DNA duplexes [1]. Inspired ...
