Polymer Translocation through Nanometer Pores

In this paper the loaded polymer transport and its escape via a nanometer size aperture, virtually by nanomembrane, the polymer being moved by an exterior electrostatic field, has been studied. Assuming a linear dependency of the friction coefficient on th ...

Heat stress destabilizes symbiotic nutrient cycling in corals

Anders Meibom, Nils Rädecker, Claudia Isabella Pogoreutz

Recurrent mass bleaching events are pushing coral reefs worldwide to the brink of ecological collapse. While the symptoms and consequences of this breakdown of the coral–algal symbiosis have been extensively characterized, our understanding of the underlyi ...

Astrocytic release of ATP through type 2 inositol 1,4,5‐trisphosphate receptor calcium signaling and social dominance behavior in mice

Maria del Carmen Sandi Perez, Jocelin Grosse, Marie-Isabelle Guillot de Suduiraut, Fiona Hollis, Eva Ramos Fernandez

Brain mitochondrial function is critical for numerous neuronal processes. We recently identified a link between brain energy and social dominance, where higher levels of mitochondrial function resulted in increased social competitive ability. The underlyin ...

Disruption of the SucT acyltransferase in Mycobacterium smegmatis abrogates succinylation of cell envelope polysaccharides

Haig Alexander Eskandarian

Similar to other prokaryotes, mycobacteria decorate their major cell envelope glycans with minor covalent substituents whose biological significance remains largely unknown. We report on the discovery of a mycobacterial enzyme, named here SucT, that adds s ...

Computational Investigation of Intracellular Signalling Cascades

Siri Camee van Keulen

In order to adjust to changes in the environment, cells can communicate via signalling cascades. A common pathway for intercellular communication is the G-protein-coupled- receptor (GPCR) signal transduction cascade which is triggered by a (chemical or phy ...

Loss of the RNA polymerase III repressor MAF1 confers obesity resistance

Johan Auwerx, Norman Lionel Moullan, Nouria Hernandez, Gilles Willemin, Rajat Singh

MAF1 is a global repressor of RNA polymerase III transcription that regulates the expression of highly abundant noncoding RNAs in response to nutrient availability and cellular stress. Thus, MAF1 function is thought to be important for metabolic economy. H ...

An atomistic view of microtubule stabilization by GTP

Paul Guichard

A microtubule is a dynamic system formed of αβ-tubulins. The presence of nonhydrolyzable guanosine-5'-triphosphate (GTP)/guanosine diphosphate (GDP) on the β-tubulins provokes microtubule polymerization/depolymerization. Despite the large number of experim ...

Comparison of Three Methods of Biocompatible Multi-Walled Carbon Nanotubes Confinement for the Development of Implantable Amperometric Adenosine-5′-Triphosphate Biosensors

Giovanni De Micheli, Sandro Carrara, Andrea Cavallini

An amperometric biosensor for adenosine 5 -triphosphate (ATP) was developed applying a competitive assay of two glucose converting enzymes: glucose oxidase (GOD) and hexokinase (HEX). Competition between GOD and HEX for glucose in presence of ATP, lead to ...

Procentriole assembly revealed by cryo-electron tomography

Paul Guichard

Centrosomes are cellular organelles that have a major role in the spatial organisation of the microtubule network. The centrosome is comprised of two centrioles that duplicate only once during the cell cycle, generating a procentriole from each mature cent ...

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 ...
