Influence of Amino Acid Substitutions in Capsid Proteins of Coxsackievirus B5 on Free Chlorine and Thermal Inactivation

Tamar Kohn, Shotaro Torii, Aleksandar Antanasijevic

The sensitivity of enteroviruses to disinfectants varies among genetically similar variants and coincides with amino acid changes in capsid proteins, although the effect of individual substitutions remains unknown. Here, we employed reverse genetics to inv ...

Metabolic, cellular and defense responses to single and co-exposure to carbamazepine and methylmercury in Dreissena polymorpha

Florian Frédéric Vincent Breider, Dominique Grandjean

Carbamazepine (CBZ) and Hg are widespread and persistent micropollutants in aquatic environments. Both pollutants are known to trigger similar toxicity mechanisms, e.g. reactive oxygen species (ROS) production. Here, their effects were assessed in the zebr ...

Epigenetic remodelling of enhancers in response to estrogen deprivation and re-stimulation

Ludovica Vanzan

Estrogen hormones are implicated in a majority of breast cancers and estrogen receptor alpha (ER), the main nuclear factor mediating estrogen signaling, orchestrates a complex molecular circuitry that is not yet fully elucidated. Here, we investigated geno ...

Microfluidic system for Caenorhabditis elegans culture and oxygen consumption rate measurements

Martinus Adela Maria Gijs, Thomas Lehnert, Matteo Cornaglia, Roger Philippe Krenger

Mitochondrial respiration is a key signature for the assessment of mitochondrial functioning and mitochondrial dysfunction is related to many diseases including metabolic syndrome and aging-associated conditions. Here, we present a microfluidic Caenorhabdi ...

MRS studies of neuroenergetics and glutamate/glutamine exchange in rats: Extensions to hyperammonemic models

Cristina Ramona Cudalbu Moldovan, Bernard Lanz, Veronika Rackayová

In vivo Magnetic Resonance Spectroscopy is a useful tool to characterize brain biochemistry as well as its alteration in a large number of major central nervous system diseases. The present review will focus on the study of the glutamate-glutamine cycle, a ...

LRH-1-dependent programming of mitochondrial glutamine processing drives liver cancer

Johan Auwerx, Arnaud Comment, Kristina Schoonjans, Dongryeol Ryu, Norman Lionel Moullan, Emine Can, Xu Wang, Maaike Hélène Oosterveer, Pan Xu, Hadrien Charles Edouard Demagny

Various tumors develop addiction to glutamine to support uncontrolled cell proliferation. Here we identify the nuclear receptor liver receptor homolog 1 (LRH-1) as a key regulator in the process of hepatic tumorigenesis through the coordination of a noncan ...

Chemical Equilibria in Formic Acid/Amine-CO2 Cycles under Isochoric Conditions using a Ruthenium(II) 1,2-Bis(diphenylphosphino)ethane Catalyst

Gabor Laurenczy, Katerina Stefania Sordakis

The equilibrium position in formic acid/amine–CO2 systems has been examined as a function of pressure and tem- perature under isochoric conditions. The homogeneous ruthe- nium(II)-1,2-bis(diphenylphosphino)ethane catalyst was active in both reactions, that ...

Extended Bottom-Up Proteomics with Secreted Aspartic Protease Sap9

Yury Tsybin, Kristina Srzentic, Unige Anna Laskay

We investigate the benefits and experimental feasibility of approaches enabling the shift from short (1.7 kDa on average) peptides in bottom-up proteomics to about twice longer (similar to 3.2 kDa on average) peptides in the so-called extended bottom-up pr ...

High-resolution spatial mapping of changes in the neurochemical profile after focal ischemia in mice

Rolf Gruetter, Hongxia Lei, Malte Alf

After ischemic stroke, the ischemic damage to brain tissue evolves over time and with an uneven spatial distribution. Early irreversible changes occur in the ischemic core, whereas, in the penumbra, which receives more collateral blood flow, the damage is ...

Structural Role of RKS Motifs in Chromatin Interactions: A Molecular Dynamics Study of HP1 Bound to a Variably Modified Histone Tail

Efthimios Kaxiras

The current understanding of epigenetic signaling assigns a central role to post-translational modifications that occur in the histone tails. In this context, it has been proposed that methylation of K9 and phosphorylation of S10 in the tail of histone H3 ...

Preparation of 5-Membered Rings via Radical Addition-Translocation-Cyclization (RATC) Processes Mediated by Diethyl Thiophosphites

Philippe Renaud, Kurt Schenk

A practical method for the formation of thiophosphonates bearing functionalized monocyclic, fused bicyclic and spirocyclic residues is presented. The procedure requires the easily available terminal alkynes as starting materials as well as commercially and ...

Histone methyl transferases and demethylases; can they link metabolism and transcription?

Johan Auwerx, Kristina Schoonjans

Heritable changes to the transcriptome that are independent to changes in the genome are defined as epigenetics. DNA methylation and posttranslational modifications of histones, such as acetylation/deacetylation and methylation/demethylation of lysine resi ...
