Atypical and distinct microtubule radial symmetries in the centriole and the axoneme of Lecudina tuzetae

Pierre Gönczy, Alexandra Bezler, Coralie Busso, Fabian Zacharias Schneider, Alexander Woglar

The centriole is a minute cylindrical organelle present in a wide range of eukaryotic species. Most centrioles have a signature ninefold radial symmetry of microtubules that is imparted to the axonemes of the cilia and flagella they template, with nine cen ...

Novel features of centriole polarity and cartwheel stacking revealed by cryo-tomography

Pierre Gönczy, Davide Demurtas, Alexandra Bezler, Sergey Nazarov, Paul Guichard, Veronika Nemcíková Villímová, Georgios Hatzopoulos

Centrioles are polarized microtubule-based organelles that seed the formation of cilia, and which assemble from a cartwheel containing stacked ring oligomers ofSAS-6 proteins. A cryo-tomography map of centrioles from the termite flagellateTrichonymphaspp. ...

Tissue- and sex-specific small RNAomes reveal sex differences in response to the environment

Laurent Keller, Pierre Gönczy, Frédéric Schütz, Alexandra Bezler, Raffaella Conconi

RNA interference (RNAi) related pathways are essential for germline development and fertility in metazoa and can contribute to inter- and trans-generational inheritance. In the nematode Caenorhabditis elegans, environmental double-stranded RNA provided by ...

Mutual Inhibition Between the Anaphase-promoting Complex and the Spindle Assembly Checkpoint in C. Elegans Embryos

Alexandra Bezler

The cell cycle orchestrates timely duplication and distribution of cellular components to daughter cells. Checkpoints operate to survey the faithful completion of specific steps during the cell cycle, thus ensuring the equal segregation of genetic material ...

Temperature gradient stimulation for cell division in C. Elegans Embryos on chip

Philippe Renaud, Pierre Gönczy, Christian Adamczyk, Alexandra Bezler, Sophie Baranek Delasoie

This paper reports on a new microfluidic device for temperature stimulation of cell in in-vitro culture. Micro- electrodes in a meander shape are embedded into the microfluidic channels to generate either a temperature gradient through the culture chamber ...

Mutual Antagonism Between the Anaphase Promoting Complex and the Spindle Assembly Checkpoint Contributes to Mitotic Timing in Caenorhabditis elegans

Pierre Gönczy, Alexandra Bezler

The anaphase promoting complex/cyclosome (APC/C) triggers the separation of sister chromatids and exit from mitosis across eukaryotic evolution. The APC/C is inhibited by the spindle assembly checkpoint (SAC) until all chromosomes have achieved bipolar att ...
