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 ...

Native Architecture of the Centriole Proximal Region Reveals Features Underlying Its 9-Fold Radial Symmetry

Pierre Gönczy, Davide Demurtas, Paul Guichard, Isabelle Fluckiger, Aitana Neves da Silva, Norbert Majubu

Centrioles are cylindrical microtubule-based structures whose assembly is critical for the formation of cilia, flagella, and centrosomes. The centriole proximal region harbors a cartwheel that dictates the 9-fold symmetry of centrioles. Although the cartwh ...

Jagged1 is the major regulator of notch-dependent cell fate in proximal airways

Freddy Radtke

Background: The Notch signaling pathway plays complex roles in developing lungs, including regulation of proximodistal fates, airway cell specification and differentiation. However, the specific Notch-mediated signals involved in lung development remain un ...

Measurement of autophagy flux in the nervous system in vivo

Bernard Schneider

Accurate methods to measure autophagic activity in vivo in neurons are not available, and most of the studies are based on correlative and static measurements of autophagy markers, leading to conflicting interpretations. Autophagy is an essential homeostat ...

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 ...

The Ciliogenic Transcription Factor RFX3 Regulates Early Midline Distribution of Guidepost Neurons Required for Corpus Callosum Development

The corpus callosum (CC) is the major commissure that bridges the cerebral hemispheres. Agenesis of the CC is associated with human ciliopathies, but the origin of this default is unclear. Regulatory Factor X3 (RFX3) is a transcription factor involved in t ...

A Notch-dependent molecular circuitry initiates pancreatic endocrine and ductal cell differentiation

Anne Grapin-Botton

In the pancreas, Notch signaling is thought to prevent cell differentiation, thereby maintaining progenitors in an undifferentiated state. Here, we show that Notch renders progenitors competent to differentiate into ductal and endocrine cells by inducing a ...

Drug development: longer-lived proteins

Stephane Kontos, Jeffrey Alan Hubbell

Protein therapeutics represent a powerful class of clinically approved drugs for the prevention and treatment of various diseases. Once administered, the biological fate of protein therapeutics is governed by the body's various complex biochemical and biop ...

Notch-dependent VEGFR3 upregulation allows angiogenesis without VEGF-VEGFR2 signalling

Freddy Radtke

Developing tissues and growing tumours produce vascular endothelial growth factors (VEGFs), leading to the activation of the corresponding receptors in endothelial cells. The resultant angiogenic expansion of the local vasculature can promote physiological ...
