Exploring the role of transcriptional and post-transcriptional processes in mRNA co-expression

Benjamin Joao Clément Antonin Hadrien Martin

Co-expression of two or more genes at the single-cell level is usually associated with functional co-regulation. While mRNA co-expression-measured as the correlation in mRNA levels-can be influenced by both transcriptional and post-transcriptional events, ...

Computational identification and experimental characterization of preferred downstream positions in human core promoters

Philipp Bucher, René Dreos

Author summary Transcription of genes by the RNA polymerase II enzyme initiates at a genomic region termed the core promoter. The core promoter is a regulatory region that may contain diverse short DNA sequence motifs/elements that confer specific properti ...

Magnetically separable TiO2/FeOx/POM accelerating the photocatalytic removal of the emerging endocrine disruptor: 2,4-dichlorophenol

Sami Rtimi, Jiajie Yu

This study presents the magnetically separable TiO2/FeOx microstructure decorated with poly-oxo-tungstate (POM) leading to the endocrine disruptor 2,4-dichlorophenol (2,4-DCP) under low intensity solar light. The fastest 2,4-DCP degradation kinetics was ob ...

Screening of structurally diverse bicyclic peptide libraries by phage display

Davide Bertoldo

Bicyclic peptides are an attractive molecule format for the development of therapeutics and research tools. Our laboratory is specialized on the development of bicyclic peptide ligands by phage display. In brief, libraries of randompeptides each containing ...

RNA-Protein interactions at AU-rich elements

Ramona Pauchard-Batschulat

The expression of many proto-oncogenes, nuclear transcription factors and cytokines is regulated post-transcriptionally by specific interactions between distinct cis-elements within the mRNA and trans-acting factors that bind to these elements and thereby ...

Genome-Wide RNA Polymerase II Profiles and RNA Accumulation Reveal Kinetics of Transcription and Associated Epigenetic Changes During Diurnal Cycles

Olivier Martin, Bart Deplancke, Felix Naef, Jacques Rougemont, Nicolas Jean Philippe Guex, Winship Herr, Mauro Delorenzi, Nouria Hernandez, Laura Symul

Interactions of cell-autonomous circadian oscillators with diurnal cycles govern the temporal compartmentalization of cell physiology in mammals. To understand the transcriptional and epigenetic basis of diurnal rhythms in mouse liver genome-wide, we gener ...

The crystal structure of the Escherichia coli RNase E apoprotein and a mechanism for RNA degradation

RNase E is an essential bacterial endoribonuclease involved in the turnover of messenger RNA and the maturation of structured RNA precursors in Escherichia coli. Here, we present the crystal structure of the E. coli RNase E catalytic domain in the apo-stat ...

Toward the design of highly efficient, readily accessible peptide N-caps for the induction of helical conformations

Richard Alan Mimna

A series of novel peptide N-caps was designed with an emphasis on ease of synthesis and an abundance of hydrogen bond acceptors. Different scaffolds based on sugars, cyclic hydrocarbons, and amino acids are developed with a variety of hydrogen bond accepto ...

The putative iron-responsive element in the human erythroid 5-aminolevulinate synthase mRNA mediates translational control

Lukas Kühn

The 52-nucleotide 5'-untranslated region of the human erythroid 5-aminolevulinate synthase mRNA contains a 28-nucleotide iron-responsive element-like stem-loop motif. We fused the 5'-untranslated region upstream to the coding sequence of the human growth h ...

A stem-loop in the 3' untranslated region mediates iron-dependent regulation of transferrin receptor mRNA stability in the cytoplasm

Lukas Kühn

Expression of the human transferrin receptor (hTR) and its mRNA is strongly induced by iron deprivation. By measuring transcription elongation rates, levels of hTR-specific nuclear RNA, and mRNA half-lives, we found this regulation to occur posttranscripti ...
