A transcriptional regulator linking quorum sensing and chitin induction to render Vibrio cholerae naturally transformable

The human pathogen Vibrio cholerae is an aquatic bacterium associated with zooplankton and their chitinous exoskeletons. On chitinous surfaces, V. cholerae initiates a developmental programme, known as natural competence, to mediate transformation, which i ...

Bioinspired, releasable quorum sensing modulators

Adrien Keith Lawrence, Karl Gademann

We demonstrate the synthesis and immobilization of natural product hybrids featuring an acyl-homoserine lactone and a nitrodopamine onto biocompatible TiO2 surfaces through an operationally simple dip-and-rinse procedure. The resulting immobilized hybrids ...

In vivo imaging reveals selective PPAR activity in the skin of peroxisome proliferator-activated receptor responsive element-luciferase reporter mice

Johan Auwerx

Peroxisome proliferator-activated receptors (PPARs) have been revealed as key regulators of several skin disorders. This has led to a growing interest in the development of drugs targeting PPARs as therapeutics for skin diseases. To evaluate skin PPAR acti ...

Bioluminescent sensor proteins for point-of-care therapeutic drug monitoring

Rudolf Griss

To ensure efficacy but avoid toxicity, many drugs require monitoring of their concentrations in the patient’s blood during therapy. Currently, therapeutic drug monitoring (TDM) is done in diagnostic laboratories that need trained personnel and expensive in ...

The Janthinobacterium sp. HH01 Genome Encodes a Homologue of the V. cholerae CqsA and L. pneumophila LqsA Autoinducer Synthases

Melanie Blokesch

Janthinobacteria commonly form biofilms on eukaryotic hosts and are known to synthesize antibacterial and antifungal compounds. Janthinobacterium sp. HH01 was recently isolated from an aquatic environment and its genome sequence was established. The genome ...

A quorum sensing-mediated switch contributes to natural transformation of Vibrio cholerae

Melanie Blokesch

There is a fundamental gap in our understanding of how horizontal gene transfer contributes to the enormous range of genetic variations that are observed among bacteria. The objective of our study was to better understand how the acquisition of genetic mat ...

Very High Throughput Electrical Cell Lysis and Extraction of Intracellular Compounds Using 3D Carbon Electrodes in Lab-on-a-Chip Devices

Philippe Renaud, Freddy Radtke, Rajwinder Lehal, Rodrigo Martinez Duarte

Here we present an electrical lysis throughput of 600 microliters per minute at high cell density (108 yeast cells per ml) with 90% efficiency, thus improving the current common throughput of one microliter per minute. We also demonstrate the extraction of ...

Quorum Sensing Contributes to Natural Transformation of Vibrio cholerae in a Species-Specific Manner

Melanie Blokesch, Patrick Martin Seitz, Gaia Francesca Marianne Suckow

Although it is a human pathogen, Vibrio cholerae is a regular member of aquatic habitats, such as coastal regions and estuaries. Within these environments, V. cholerae often takes advantage of the abundance of zooplankton and their chitinous molts as a nut ...

Refined quorum systems

Rachid Guerraoui, Marko Vukolic

It is considered good distributed computing practice to devise object implementations that tolerate contention, periods of asynchrony and a large number of failures, but perform fast if few failures occur, the system is synchronous and there is no contenti ...

Synthetic Studies on Daphmanidin C and Maytenone Based on Biosynthetic Considerations and Natural Product Hybrids as Tools for Quorum Sensing

Adrien Keith Lawrence

The isolation and characterisation of natural products remains a challenge in chemistry owing to nature's magnificent diversity. Natural products or natural product derivatives have always been used in traditional medicine to treat a variety of diseases. T ...
