Theoretical analysis of divalent cation effects on aptamer recognition of neurotransmitter targets

Nako Nakatsuka, Dmitry Momotenko, Annina Stuber

Aptamer-based sensing of small molecules such as dopamine and serotonin in the brain, requires characterization of the specific aptamer sequences in solutions mimicking the in vivo environment with physiological ionic concentrations. In particular, divalen ...

RNA-based nanomedicines and their clinical applications

Yi Wang

RNA-based nanomedicines encompass a range of therapeutic approaches that utilize RNA molecules or molecules that target RNAs for the treatment or prevention of diseases. These include antisense oligonucleotides (ASOs), small interfering RNAs (siRNAs), endo ...

Polymeric integration of structure-switching aptamers on transistors for histamine sensing

Nako Nakatsuka, Mattia Petrelli

Aptamers that undergo large conformational rearrangements at the surface of electrolyte-gated field-effect transistor (EG-FETs)-based biosensors can overcome the Debye length limitation in physiological high ionic strength environments. For the sensitive d ...

Divalent Cation Dependence Enhances Dopamine Aptamer Biosensing

Nako Nakatsuka

Oligonucleotide receptors (aptamers), which change conformation upon target recognition, enable electronic biosensing under high ionic-strength conditions when coupled to field-effect transistors (FETs). Because highly negatively charged aptamer backbones ...

A fully joint Bayesian quantitative trait locus mapping of human protein abundance in plasma

Anthony Christopher Davison, Jörg Hager, Hélène Ruffieux, Radu Popescu

Molecular quantitative trait locus (QTL) analyses are increasingly popular to explore the genetic architecture of complex traits, but existing studies do not leverage shared regulatory patterns and suffer from a large multiplicity burden, which hampers the ...

Ecological implications of gene regulation by TfoX and TfoY among diverse Vibrio species

Melanie Blokesch, Candice Stoudmann, Noémie Matthey, Lisa Christina Metzger, Esther Jeanne Collas

Bacteria of the genus Vibrio are common members of aquatic environments where they compete with other prokaryotes and defend themselves against grazing predators. A macromolecular protein complex called the type VI secretion system (T6SS) is used for both ...

Phenylalanine Monitoring via Aptamer-Field-Effect Transistor Sensors

Nako Nakatsuka

Determination of the amino acid phenylalanine is important for lifelong disease management in patients with phenylketonuria, a genetic disorder in which phenylalanine accumulates and persists at levels that alter brain development and cause permanent neuro ...

Regulation of the Corrinoid Metabolism in Desulfitobacteria

Christof Holliger, Julien Maillard, Emmanuelle Rohrbach, Aurélie Duret

The corrinoid cofactor is essential to organohalide respiration (OHR) as key element in virtually all reductive dehalogenases. Desulfitobacteria, and more particularly D. hafniense, represent a group of versatile OHR bacteria able to produce corrinoids de ...

Corrinoid auxotrophy in the obligate organohalide-respiring Dehalobacter restrictus strain PER-K23

Christof Holliger, Julien Maillard, Yue Lu, Aamani Rupakula Boyanapalli, Hauke Smidt

Background Corrinoids are an essential cofactor of reductive dehalogenases, the key enzymes of organohalide respiration (OHR). Dehalobacter restrictus is an obligate OHR bacterium (OHRB) able to conserve energy with tetrachloroethene, but is unable to de n ...
