Principles of checkpoint override

Why biological quality-control systems fail is often mysterious. Specifically, checkpoints such as the DNA damage checkpoint or the spindle assembly checkpoint are overriden after prolonged arrests allowing cells to continue dividing despite the continued ...

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

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 ...

TRACMIT: An effective pipeline for tracking and analyzing cells on micropatterns through mitosis

Pierre Gönczy, Olivier Burri, Arne Seitz, Benita Wolf

The use of micropatterns has transformed investigations of dynamic biological processes by enabling the reproducible analysis of live cells using time-lapse fluorescence microscopy. With micropatterns, thousands of individual cells can be efficiently image ...

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 ...

Analysis of S. pombe SIN protein association to the SPB reveals two genetically separable states of the SIN

Michaël Unser, Daniel Sage, Jacques Rougemont, Viesturs Simanis, Andrea Krapp, Daniel Andreas Schmitter, Anastasia Chasapi, Ioannis Xenarios

The Schizosaccharomyces pombe septation initiation network (SIN) regulates cytokinesis, and asymmetric association of SIN proteins with the mitotic spindle pole bodies (SPBs) is important for its regulation. Here, we have used semi-automated image analysis ...

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 ...

Optimization of the analogue-sensitive Cdc2/Cdk1 mutant by in vivo selection eliminates physiological limitations to its use in cell cycle analysis

Viesturs Simanis

Analogue-sensitive (as) mutants of kinases are widely used to selectively inhibit a single kinase with few off-target effects. The analogue-sensitive mutant cdc2-as of fission yeast (Schizosaccharomyces pombe) is a powerful tool to study the cell cycle, bu ...

Characterizing the localization and role of lin-5 and era-1 mRNAs in early C. elegans embryos

Zoltán Péter Spiró

Asymmetric cell division is essential for the generation of diversity during development and the function of stem cell lineages. The Caenorhabditis elegans zygote is an attractive model to investigate the mechanisms of spindle positioning during asymmetric ...

Clathrin regulates centrosome positioning by promoting acto-myosin cortical tension in C. elegans embryos

Pierre Gönczy, Alessandro De Simone, Sylvain Träger, Kalyani Thyagarajan

Regulation of centrosome and spindle positioning is crucial for spatial cell division control. The one-cell Caenorhabditis elegans embryo has proven attractive for dissecting the mechanisms underlying centrosome and spindle positioning in a metazoan organi ...

MISP is a novel Plk1 substrate required for proper spindle orientation and mitotic progression

Pierre Gönczy, Sachin Kotak

Precise positioning of the mitotic spindle determines the correct cell division axis and is crucial for organism development. Spindle positioning is mediated through a cortical machinery by capturing astral microtubules, thereby generating pushing/pulling ...
