Bactericidal effect of tetracycline in E. coli strain ED1a may be associated with ribosome dysfunction

Camille Véronique Bernadette Goemans, Christian Eugen Zimmerli, Martin Beck

Ribosomes translate the genetic code into proteins. Recent technical advances have facilitated in situ structural analyses of ribosome functional states inside eukaryotic cells and the minimal bacterium Mycoplasma. However, such analyses of Gram-negative b ...

Bacterial matrix metalloproteases and serine proteases contribute to the extra-host inactivation of enteroviruses in lake water

Tamar Kohn, Virginie Bachmann

Enteroviruses are ubiquitous contaminants of surface waters, yet their fate in presence of microbial congeners is poorly understood. In this work, we investigated the inactivation of Echovirus-11 (E11) and Coxsackievirus-A9 (CVA9) by bacteria isolated from ...

Boosted Pro-Inflammatory Activity in Human PBMCs by Lipopolysaccharide and SARS-CoV-2 Spike Protein Is Regulated by alpha-1 Antitrypsin

Florian Maria Wurm, Divor Kiseljak

For the treatment of severe COVID-19, supplementation with human plasma-purified alpha-1 antitrypsin (AAT) to patients is currently considered. AAT inhibits host proteases that facilitate viral entry and possesses broad anti-inflammatory and immunomodulato ...

Long-term imaging, automated high-content phenotyping and sorting of C. elegans larvae and embryos using microfluidic platforms

Hüseyin Baris Atakan

C. elegans is frequently studied to address fundamental biological questions motivated by its short life cycle, small size, hermaphrodite behavior and well-annotated genome. In this work, we present novel microfluidic platforms that support long-term cultu ...

A design of experiment approach for efficient multi-parametric drug testing using a Caenorhabditis elegans model

Martinus Gijs, Matteo Cornaglia, Raphaël Etienne Jean Trouillon, Maria Cristina Letizia, Giuseppe Tranchida

When studying the drug effectiveness towards a target model, one should distinguish the effects of the drug itself and of all the other factors that could influence the screening outcome. This comprehensive knowledge is crucial, especially when model organ ...

Microfluidic high-content phenotypic screening on a Caenorhabditis elegans model

Maria Cristina Letizia

Caenorhabditis elegans is a performant model system for studying human biological processes and diseases and for pre-clinical phenotyping screenings of compounds. Microfluidics has been instrumental in enabling C. elegans-based drug assays, facilitating th ...

Mitochondrial stress signalling and its impacts on physiology

Adrienne Joëlle Laurence Mottis

Mitochondria are responsible for respiration and energy harvesting across the eukaryotic kingdom. They also take part in other cellular processes like intermediary metabolism. As a result, mitochondrial function directly impacts organismal features such as ...

Tetracyclines Disturb Mitochondrial Function across Eukaryotic Models: A Call for Caution in Biomedical Research

Johan Auwerx, Bart Deplancke, Richardus Houtkooper, Laurent Mouchiroud, Dongryeol Ryu, Xu Wang, Evan Graehl Williams, Adrienne Joëlle Laurence Mottis, Virginija Jovaisaite, Norman Lionel Moullan

In recent years, tetracyclines, such as doxycycline, have become broadly used to control gene expression by virtue of the Tet-on/Tet-off systems. However, the wide range of direct effects of tetracycline use has not been fully appreciated. We show here tha ...

Tetracycline Antibiotics Impair Mitochondrial Function and Its Experimental Use Confounds Research

Johan Auwerx, Laurent Mouchiroud, Richardus Houtkooper

Tetracyclines, a class of antibiotics that target bacterial translation, are commonly used in research for inducible gene expression using Tet-ON/Tet-OFF systems. However, such tetracycline-inducible systems carry a risk. Given that mitochondria have a "ba ...

C-linked disaccharide analogue of the Thomsen-Friedenreich (T)-epitope alpha-O-conjugated to L-serine

Pierre Vogel, Loay Awad

Condensation of a silylated beta-D-galactopyranosylaldehyde (3) with isolevoglucosenone (4) in the presence of Et(2)AII provided bicyclic enone 5. Subsequent addition of BnNHOMe gave adduct 6, which was converted into 4-O-acetyl-1,6-anhydro-3-C-[ R)1.3,4,5 ...
