Sperm-contributed centrioles segregate stochastically into blastomeres of 4-cell stage Caenorhabditis elegans embryos
Pierre Gönczy, Fernando Romero Balestra
Whereas both sperm and egg contribute nuclear genetic material to the zygote in metazoan organisms, the inheritance of other cellular constituents is unequal between the 2 gametes. Thus, 2 copies of the centriole are contributed solely by the sperm to the ...
GENETICS SOCIETY AMERICA2023Dissecting centriole fate in C. elegans development
The presence of centrioles is critical for fundamental cell and developmental processes, including polarity, migration and division. Although centrioles are present in most proliferating cells, they are thought to vanish after cell cycle exit in some diffe ...
EPFL2022Structures of SAS-6 coiled coil hold implications for the polarity of the centriolar cartwheel
Pierre Gönczy, Georgios Hatzopoulos
Centrioles are eukaryotic organelles that template the formation of cilia and flagella, as well as organize the microtubule network and the mitotic spindle in animal cells. Centrioles have proximal-distal polarity and a 9 fold radial symmetry imparted by a ...
CELL PRESS2022TRIM37 prevents formation of centriolar protein assemblies by regulating Centrobin
Pierre Gönczy, Coralie Busso, Benita Wolf, Fernando Romero Balestra, Tessa Vivianne Averink, Alizée Buff
TRIM37 is an E3 ubiquitin ligase mutated in Mulibrey nanism, a disease with impaired organ growth and increased tumor formation. TRIM37 depletion from tissue culture cells results in supernumerary foci bearing the centriolar protein Centrin. Here, we chara ...
ELIFE SCIENCES PUBLICATIONS LTD2021A helical inner scaffold provides a structural basis for centriole cohesion
Henning Paul-Julius Stahlberg, Davide Gambarotto, Paul Guichard, Virginie Hamel
The ninefold radial arrangement of microtubule triplets (MTTs) is the hallmark of the centriole, a conserved organelle crucial for the formation of centrosomes and cilia. Although strong cohesion between MTTs is critical to resist forces applied by ciliary ...
2020Novel features of centriole polarity and cartwheel stacking revealed by cryo-tomography
Davide Demurtas, Georgios Hatzopoulos, Sergey Nazarov, Alexandra Bezler, Paul Guichard, Veronika Nemcíková Villímová
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. ...
2020Centriole foci persist in starfish oocytes despite Polo-like kinase 1 inactivation or loss of microtubule nucleation activity
Pierre Gönczy, Nils Kalbfuss, Marie Juliette Ségolène Pierron
Centrioles must be eliminated or inactivated from the oocyte to ensure that only the two functional centrioles contributed by the sperm are present in the zygote. Such removal can occur during oogenesis, as in Drosophila, where departure of Polo kinase fro ...
