Chiral N-Heterocyclic Carbene Ligands for Asymmetric Catalysis

N-Heterocyclic carbenes (NHCs) are the ligands of choice in a large variety of transformations entailing different transition metals. However, the number of chiral NHCs suitable as stereocontrolling ligands in asymmetric catalysis remains limited. In parti ...

Lossy compression of quality scores in differential gene expression: A first assessment and impact analysis

Ana Angelica Hernandez Lopez

High-throughput sequencing of RNA molecules has enabled the quantitative analysis of gene expression at the expense of storage space and processing power. To alleviate these prob- lems, lossy compression methods of the quality scores associated to RNA sequ ...

The Structure of the Protonated Serine Octamer

Ursula Röthlisberger, Thomas Rizzo, Stephan Warnke, Marta Andreia Da Silva Perez, Valeriu Scutelnic, Aurelien Stephen Arnaud Gregor, Carsten Baldauf

The amino acid serine has long been known to form a protonated “magic-number” cluster containing eight monomer units that shows an unusually high abundance in mass spectra and has a remarkable homochiral preference. Despite many experimental and theoretica ...

Aptamer–field-effect transistors overcome Debye length limitations for small-molecule sensing

Nako Nakatsuka, Yang Yang, Bowen Zhu

Detection of analytes by means of field-effect transistors bearing ligand-specific receptors is fundamentally limited by the shielding created by the electrical double layer (the “Debye length” limitation). We detected small molecules under physiological h ...

Development of Site-Specific Mg2+-RNA Force Field Parameters: A Dream or Reality? Guidelines from Combined Molecular Dynamics and Quantum Mechanics Simulations

Ursula Röthlisberger, Giulia Palermo, Lorenzo Casalino

The vital contribution of Mg2+ ions to RNA biology is challenging to dissect at the experimental level. This calls for the integrative support of atomistic simulations, which at the classical level are plagued by limited accuracy. Indeed, force fields intr ...

Differential Gene Expression with Lossy Compression of Quality Scores in RNA-Seq Data

Marco Mattavelli, Claudio Paolo Alberti, Ana Angelica Hernandez Lopez

High-Throughput sequencing of RNA molecules has enabled the quantitative analysis of the expression of genes at the expense of storage space and processing power. To help alleviate these problems, lossy compression methods of the quality scores associated ...

A practical qPCR approach to detect TERRA, the elusive telomeric repeat-containing RNA

Joachim Lingner, Marianna Feretzaki

Telomeres, the heterochromatic structures that protect the ends of the chromosomes, are transcribed into a class of long non-coding RNAs, telomeric repeat-containing RNAs (TERRA), whose transcriptional regulation and functions are not well understood. The ...

Placeholder factors in ribosome biogenesis: please, pave my way

The synthesis of cytoplasmic eukaryotic ribosomes is an extraordinarily energy-demanding cellular activity that occurs progressively from the nucleolus to the cytoplasm. In the nucleolus, precursor rRNAs associate with a myriad of trans-acting factors and ...

The effects of mitochondrial- and histone stress on the C. elegans transcriptome

Johan Auwerx, Maroun Bou Sleiman

The aim of this study was to explore whether mitochondrial- and histone stress cause any common changes in global gene expression. For this experiment, we performed RNA sequencing from control RNAi, cco-1 RNAi (mitochondrial stress) and his-3 RNAi (histone ...
