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 ...

Phage selection of peptide macrocycles against b-catenin to interfere with Wnt signaling

Christian Heinis, Pierre Vincent Dessen, Davide Bertoldo, Maola Khan Mohammad Golam

Upregulation of b-catenin, the primary mediator of the Wnt signaling pathway, plays an important role in the tumorigenesis of several types of human cancer. Targeting b-catenin to interfere with its ability to serve as a translational co-activator is consi ...

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 ...

Two Nucleus-Localized CDK-Like Kinases With Crucial Roles for Malaria Parasite Erythrocytic Replication Are Involved in Phosphorylation of Splicing Factor

The kinome of the human malaria parasite Plasmodium falciparum comprises representatives of most eukaryotic protein kinase groups, including kinases which regulate proliferation and differentiation processes. Despite extensive research on most plasmodial e ...

PARP-1 Inhibition Increases Mitochondrial Metabolism through SIRT1 Activation

Johan Auwerx, Kristina Schoonjans, Carlos Canto Alvarez, Richardus Houtkooper, Hiroyasu Yamamoto

SIRT1 regulates energy homeostasis by controlling the acetylation status and activity of a number of enzymes and transcriptional regulators. The fact that NAD(+) levels control SIRT1 activity confers a hypothetical basis for the design of new strategies to ...

Selection of molecular structure and delivery of RNA oligonucleotides to activate TLR7 versus TLR8 and to induce high amounts of IL-12p70 in primary human monocytes

Andrea Ablasser

Detection of non-self RNA by TLRs within endosomes and by retinoic acid-inducible gene I (RIG-I)-like helicases in the cytosol is central to mammalian antiviral immunity. In this study, we used pathway-specific agonists and targeted delivery to address RNA ...
