Chemical Genetic Screen Identifies Natural Products that Modulate Centriole Number

Pierre Gönczy, Kai Johnsson, Michele Graciotti, Zhou Fang

Centrioles are microtubule-based organelles found in most eukaryotic cells and that are critical for the formation of cilia and flagella, as well as of centrosomes in animal cells. The number of centrioles must be strictly regulated in proliferating cells ...

Ultrastructural analysis of adult mouse neocortex comparing aldehyde perfusion with cryo fixation

Graham Knott, Carl Petersen, Natalya Korogod

Analysis of brain ultrastructure using electron microscopy typically relies on chemical fixation. However, this is known to cause significant tissue distortion including a reduction in the extracellular space. Cryo fixation is thought to give a truer repre ...

Purification of centrosomes from mammalian cell lines

Paul Guichard

Centrosomes act as the main microtubule-organizing centre of animal cells and play critical roles in the cell, such as mitotic spindle organization, cell polarity, and motility. They are composed of two barrel-shaped structures, the centrioles, surrounded ...

The Caenorhabditis elegans protein SAS-5 forms large oligomeric assemblies critical for centriole formation

Pierre Gönczy, Georgios Hatzopoulos

Centrioles are microtubule-based organelles crucial for cell division, sensing and motility. In Caenorhabditis elegans, the onset of centriole formation requires notably the proteins SAS-5 and SAS-6, which have functional equivalents across eukaryotic evol ...

SAS-1 Is a C2 Domain Protein Critical for Centriole Integrity in C. elegans

Graham Knott, Pierre Gönczy, Simon Blanchoud, Lukas von Tobel, Tamara Mikeladze-Dvali

Centrioles are microtubule-based organelles important for the formation of cilia, flagella and centrosomes. Despite progress in understanding the underlying assembly mechanisms, how centriole integrity is ensured is incompletely understood, including in sp ...

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

Pierre Gönczy, Paul Guichard, Georgios Hatzopoulos, Virginie Hamel

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 ...

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 ...

Cortical dynein is critical for proper spindle positioning in human cells

Pierre Gönczy, Coralie Busso, Sachin Kotak

Correct spindle positioning is fundamental for proper cell division during development and in stem cell lineages. Dynein and an evolutionarily conserved ternary complex (nuclear mitotic apparatus protein [NuMA]–LGN–Gα in human cells and LIN-5–GPR-1/2–Gα in ...
