Differential Effects of Post-translational Modifications on the Membrane Interaction of Huntingtin Protein

Hilal Lashuel, Matteo Dal Peraro, Luciano Andres Abriata, Charlotte Julie Caroline Gehin, Zhidian Zhang

Huntington's disease is a neurodegenerative disorder caused by an expanded polyglutamine stretch near the N-terminus of the huntingtin (HTT) protein, rendering the protein more prone to aggregate. The first 17 residues in HTT (Nt17) interact with lipid mem ...

Androgen Receptor Signaling in in vivo models of Estrogen Receptor-positive Breast Cancer and Normal Breast Epithelium

Andrea Agnoletto

Steroid hormone receptors (HRs) are ligand-activated transcription factors that play a pivotal role in breast development and carcinogenesis. It is well established that estrogen receptor (ER) signaling is a major proliferative driver in estrogen receptor ...

Competing Effects of Hydration and Cation Complexation in Single-Chain Alginate

Zezhong Li

Alginic acid, a naturally occurring anionic polyelectrolyte, forms strong physically cross-linked hydrogels in the presence of metal cations. The latter engage in electrostatic interactions that compete with intra- and intermolecular hydrogen bonds, determ ...

Detection of TERRA R-Loops at Human Telomeres

Joachim Lingner, Marianna Feretzaki, Galina Glousker, Rita Valador Fernandes

R-loops are three-stranded nucleic acid structures composed of a DNA–RNA hybrid and a displaced DNA strand. The long noncoding RNA TERRA forms R-loops at telomeres influencing the telomeric chromatin composition and impacting on telomere maintenance mechan ...

Modeling non-covalent interactions in condensed phase

Veronika Juraskova

The modeling of non-covalent interactions, solvation effects, and chemical reactions in complex molecular environment is a challenging task. Current state-of-the-art approaches often rely on static computations using implicit solvent models and harmonic ap ...

The Nt17 Domain and its Helical Conformation Regulate the Aggregation, Cellular Properties and Neurotoxicity of Mutant Huntingtin Exon 1

Giovanni Dietler, Hilal Lashuel, Anass Chiki, Francesco Simone Ruggeri, Anne-Laure Mahul Mellier, Urszula Beata Cendrowska, Sophie Vieweg, Nathan Alain Denis Riguet, Sean Michael Deguire

Converging evidence points to the N-terminal domain comprising the first 17 amino acids of the Huntingtin protein (Nt17) as a key regulator of its aggregation, cellular properties and toxicity. In this study, we further investigated the interplay between N ...

Development of Photocatalysts towards the Visible-Light driven C-Terminal Bioconjugation of Peptides and Proteins

Marion Marie-Agnès Garreau

If small molecules have led to tremendous progress in curing diseases, new therapeutic agents such as peptides or antibody-drugs conjugates have emerged as a highly promising next generation of pharmaceuticals. As for small molecules, their derivatization ...

Skeletal muscle enhancer interactions identify genes controlling whole-body metabolism

Johan Auwerx, Martin Rainer Wohlwend

Obesity and type 2 diabetes (T2D) are metabolic disorders influenced by lifestyle and genetic factors that are characterized by insulin resistance in skeletal muscle, a prominent site of glucose disposal. Numerous genetic variants have been associated with ...

Genetically Encoded Activators of Small Molecules for Imaging and Drug Delivery

Zacharias Thiel, Pablo Rivera Fuentes, Jade Noémie Nam Nguyen

Chemical biologists have developed many tools based on genetically encoded macromolecules and small, synthetic compounds. The two different approaches are extremely useful, but they have inherent limitations. In this Minireview, we highlight examples of st ...
