Mechanisms of axoneme and centriole elimination in Naegleria gruberi

Graham Knott, Pierre Gönczy, Mary-Claude Croisier-Coeytaux, Coralie Busso, Gabriela Garcia Rodriguez, Alexander Woglar

The early branching eukaryote Naegleria gruberi can transform transiently from an amoeboid life form lacking centrioles and flagella to a flagellate life form where these elements are present, followed by reversion to the amoeboid state. The mechanisms imp ...

Centriole elimination during Caenorhabditis elegans oogenesis initiates with loss of the central tube protein SAS-1

Pierre Gönczy, Mary-Claude Croisier-Coeytaux, Coralie Busso, Tamara Mikeladze-Dvali, Marie Juliette Ségolène Pierron, Keshav Jha, Alexander Woglar

In most metazoans, centrioles are lost during oogenesis, ensuring that the zygote is endowed with the correct number of two centrioles, which are paternally contributed. How centriole architecture is dismantled during oogenesis is not understood. Here, we ...

Molecular architecture of the C. elegans centriole

Pierre Gönczy, Coralie Busso, Marie Juliette Ségolène Pierron, Fabian Zacharias Schneider, Keshav Jha, Alexander Woglar

Uncovering organizing principles of organelle assembly is a fundamental pursuit in the life sciences. Caenorhabditis elegans was key in identifying evolutionary conserved components governing assembly of the centriole organelle. However, localizing these c ...

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 ...

TRIM37 prevents formation of centriolar protein assemblies by regulating Centrobin

Pierre Gönczy, Coralie Busso, Fernando Romero Balestra, Benita Wolf, 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 ...

Live imaging screen reveals that TYRO3 and GAK ensure accurate spindle positioning in human cells

Pierre Gönczy, Coralie Busso, Benita Wolf

Proper spindle positioning is crucial for spatial cell division control. Spindle positioning in human cells relies on a ternary complex comprising G alpha i1-3, LGN and NuMA, which anchors dynein at the cell cortex, thus enabling pulling forces to be exert ...

Aurora A depletion reveals centrosome-independent polarization mechanism in Caenorhabditis elegans

Pierre Gönczy, Coralie Busso, Lukas von Tobel, Christian Gentili, Marie Juliette Ségolène Pierron, Kerstin Klinkert Fabbri, Sarah Herrman

How living systems break symmetry in an organized manner is a fundamental question in biology. In wild-type Caenorhabditis elegans zygotes, symmetry breaking during anterior-posterior axis specification is guided by centrosomes, resulting in anterior-direc ...

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

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

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 ...

Zika virus causes supernumerary foci with centriolar proteins and impaired spindle positioning

Pierre Gönczy, Coralie Busso, Benita Wolf

Zika virus (ZIKV) causes congenital microcephaly. Although ZIKV can impair cell cycle progression and provoke apoptosis, which probably contributes to disease aetiology through depletion of neural progenitor cells, additional cellular mechanisms may be imp ...

Aurora A kinase regulates proper spindle positioning in C-elegans and in human cells

Pierre Gönczy, Coralie Busso, Sachin Kotak

Accurate spindle positioning is essential for error-free cell division. The one-cell Caenorhabditis elegans embryo has proven instrumental for dissecting mechanisms governing spindle positioning. Despite important progress, how the cortical forces that act ...

Cellular hallmarks reveal restricted aerobic metabolism at thermal limits

Aitana Neves da Silva, Pierre Gönczy, Coralie Busso

All organisms live within a given thermal range, but little is known about the mechanisms setting the limits of this range. We uncovered cellular features exhibiting signature changes at thermal limits in Caenorhabditis elegans embryos. These included chan ...

Quantitative Analysis and Modeling Probe Polarity Establishment in C. elegans Embryos

Felix Naef, Simon Blanchoud, Pierre Gönczy, Coralie Busso

Cell polarity underlies many aspects of metazoan development and homeostasis, and relies notably on a set of PAR proteins located at the cell cortex. How these proteins interact in space and time remains incompletely understood. We performed a quantitative ...

NuMA interacts with phosphoinositides and links the mitotic spindle with the plasma membrane

Pierre Gönczy, Coralie Busso, Sachin Kotak

The positioning and the elongation of the mitotic spindle must be carefully regulated. In human cells, the evolutionary conserved proteins LGN/Gai1-3 anchor the coiled-coil protein NuMA and dynein to the cell cortex during metaphase, thus ensuring proper s ...

NuMA phosphorylation by CDK1 couples mitotic progression with cortical dynein function

Pierre Gönczy, Coralie Busso, Sachin Kotak

Spindle positioning and spindle elongation are critical for proper cell division. In human cells, an evolutionary conserved ternary complex (NuMA/LGN/Gαi) anchors dynein at the cortex during metaphase, thus ensuring correct spindle positioning. Whether thi ...
