Sperm-contributed centrioles segregate stochastically into blastomeres of 4-cell stage Caenorhabditis elegans embryos

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 ...

Extensive programmed centriole elimination unveiled in C. elegans embryos

Pierre Gönczy, Nils Kalbfuss

Centrioles are critical for fundamental cellular processes, including signaling, motility, and division. The extent to which centrioles are present after cell cycle exit in a developing organism is not known. The stereotypical lineage of Caenorhabditis ele ...

TRIM37 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 ...

Centriole 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 ...

Trait-specific dispersal of bacteria in heterogeneous porous environments: from pore to porous medium scale

Tom Ian Battin, Hannes Markus Peter, Filippo Miele, David Scheidweiler

The dispersal of organisms controls the structure and dynamics of populations and communities, and can regulate ecosystem functioning. Predicting dispersal patterns across scales is important to understand microbial life in heterogeneous porous environment ...

A 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 ...

Centriole assembly at a glance

Pierre Gönczy, Georgios Hatzopoulos

The centriole organelle consists of microtubules (MTs) that exhibit a striking 9-fold radial symmetry. Centrioles play fundamental roles across eukaryotes, notably in cell signaling, motility and division. In this Cell Science at a Glance article and accom ...

Multicolor single-particle reconstruction of protein complexes

Pierre Gönczy, Suliana Manley, Kyle Michael Douglass, Christian Sieben, Niccolo Banterle

Single-particle reconstruction (SPR) from electron microscopy (EM) images is widely used in structural biology, but it lacks direct information on protein identity. To address this limitation, we developed a computational and analytical framework that reco ...
