Multiscale light-sheet organoid imaging framework

Live imaging of organoid growth remains a challenge: it requires long-term imaging of several samples simultaneously and dedicated analysis pipelines. Here the authors report an experimental and image processing framework to turn long-term light-sheet imag ...

Discovering Regulators of Centriole Biogenesis through siRNA-Based Functional Genomics in Human Cells

Pierre Gönczy, Petr Strnad, Fernando Romero Balestra, Isabelle Fluckiger

Centrioles are essential for forming cilia, flagella, and centrosomes and are thus critical for a range of fundamental cellular processes. Despite their importance, the mechanisms governing centriole biogenesis remain incompletely understood. We performed ...

Analysis of centriole elimination during C. elegans oogenesis

Pierre Gönczy, Graham Knott, Petr Strnad, Lukas von Tobel, Tamara Mikeladze-Dvali

Centrosomes are the principal microtubule organizing centers (MTOCs) of animal cells and comprise a pair of centrioles surrounded by pericentriolar material (PCM). Centriole number must be carefully regulated, notably to ensure bipolar spindle formation an ...

Spindle positioning in human cells relies on proper centriole formation and on the microcephaly proteins CPAP and STIL

Pierre Gönczy, Petr Strnad, Debora Keller, Fernando Romero Balestra, Gregor Kohlmaier

Patients with MCPH (autosomal recessive primary microcephaly) exhibit impaired brain development, presumably due to the compromised function of neuronal progenitors. Seven MCPH loci have been identified, including one that encodes centrosome protein 4.1 as ...

Mechanisms of procentriole formation

Pierre Gönczy, Petr Strnad

The centrosome comprises a pair of centrioles and associated pericentriolar material, and it is the principal microtubule-organizing centre of most animal cells. Like the genetic material, the centrosome is duplicated once and only once during the cell cyc ...

Regulated HsSAS-6 levels ensure formation of a single procentriole per centriole during the centrosome duplication cycle

Pierre Gönczy, Petr Strnad

Centrosome duplication involves the formation of a single procentriole next to each centriole, once per cell cycle. The mechanisms governing procentriole formation and those restricting its occurrence to one event per centriole are poorly understood. Here, ...

Chattez avec Graph Search

Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.

AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
