Identification of Chlamydomonas Central Core Centriolar Proteins Reveals a Role for Human WDR90 in Ciliogenesis

Pierre Gönczy, Romain Hamelin, Florence Armand, Coralie Busso, Paul Guichard, Virginie Hamel, Isabelle Fluckiger

Centrioles are evolutionarily conserved macromolecular structures that are fundamental to form cilia, flagella, and centrosomes. Centrioles are 9-fold symmetrical microtubule-based cylindrical barrels comprising three regions that can be clearly distinguis ...

Pro-oxidant effects of nano-TiO2 on Chlamydomonas reinhardtii during short-term exposure

Olivier Martin, Paul Bowen, Christian Santschi, Lionel André Maurizi, Volodymyr Koman, Nadia Rachel Von Moos, Amarnath Jayaprakash

This study sheds light on the short-term dynamics of pro-oxidant processes related to the exposure of C. reinhardtii microalgae to nano-TiO2 using (a) conventional fluorescence probes for cellular pro-oxidant process and (b) a recently developed cytochrome ...

Multiscattering-enhanced optical biosensor: multiplexed, non-invasive and continuous measurements of cellular processes

Christian Santschi, Olivier Martin, Volodymyr Koman

The continuous measurement of uptake or release of biomarkers provides invaluable information for understanding and monitoring the metabolism of cells. In this work, a multiscattering-enhanced optical biosensor for the multiplexed, non-invasive, and contin ...

Linking toxicity and adaptive responses across the transcriptome, proteome, and phenotype of Chlamydomonas reinhardtii exposed to silver

Kristin Schirmer, Laura Sigg, Renata Behra

Understanding mechanistic and cellular events underlying a toxicological outcome allows the prediction of impact of environmental stressors to organisms living in different habitats. A systems-based approach aids in characterizing molecular events, and the ...

Correlative multicolor 3D SIM and STORM microscopy

Pierre Gönczy, Arne Seitz, Paul Guichard, Romain Guiet, Virginie Hamel, Isabelle Fluckiger, Mathias Fournier

Within the last decade, super-resolution methods that surpass the diffraction limit of light microscopy have provided invaluable insight into a variety of biological questions. Each of these approaches has inherent advantages and limitations, such that the ...

Caenorhabditis elegans centriolar protein SAS-6 forms a spiral that is consistent with imparting a ninefold symmetry

Pierre Gönczy, Virginie Hamel, Georgios Hatzopoulos, Paul Guichard, Isabelle Fluckiger

Centrioles are evolutionary conserved organelles that give rise to cilia and flagella as well as centrosomes. Centrioles display a characteristic ninefold symmetry imposed by the spindle assembly abnormal protein 6 (SAS-6) family. SAS-6 from Chlamydomonas ...

Sensing the dynamics of oxidative stress using enhanced absorption in protein-loaded random media

Olivier Martin, Christian Santschi, Guillaume Suarez

Reactive oxygen species play a key role in cell signalling and oxidative stress mechanisms, therefore, sensing their production by living organisms is of fundamental interest. Here we describe a novel biosensing method for extracellular detection of endoge ...

Multiple-endpoint assay provides a detailed mechanistic view of responses to herbicide exposure in Chlamydomonas reinhardtii

Kristin Schirmer, Renata Behra

The release of herbicides into the aquatic environment raises concerns about potential detrimental effects on ecologically important non-target species, such as unicellular algae, necessitating ecotoxicological risk assessment. Algal toxicity tests based o ...

Cell-wall-dependent effect of carboxyl-CdSe/ZnS quantum dots on lead and copper availability to green microalgae

Miguel Garcia

The present study examines the effect of carboxyl-CdSe/ZnS quantum dots (QDs) on Cu and PI) availability to microalgae with different cell wall characteristics: Chlorella kesslerii possessing a cellulosic cell wall and two strains of Chlamydomonas reinhard ...

Molecular analysis of the biodiversity of protists in hydrocarbon-polluted and pristine soils

Enrique Lara

Eukaryotic microorganisms are an essential component of the Earth's global diversity. It is believed that the number of protistan taxa far outnumbers the one of viruses and bacteria. The taxonomic classification of these organisms, which also represent the ...
