Deciphering the molecular events leading to the global restoration of the chromatin landscape during mitotic exit

Two fundamental properties of embryonic stem cells (ESCs) are their ability to self-renew and differentiate into all somatic cell types. Maintenance of their identity faces major challenges when transitioning through mitosis, as most DNA-binding proteins a ...

Pulchelloid A, a sesquiterpene lactone from the Canadian prairie plant Gaillardia aristata inhibits mitosis in human cells

Pierre Gönczy, Georgios Hatzopoulos, Tatiana Favez

Background The Canadian prairie ecosystem presents a rich source of natural products from plants that are subjected to herbivory by grazing mammals. This type of ecological competition may contribute to the production of natural products of interest in cel ...

Computer simulations reveal mechanisms that organize nuclear dynein forces to separate centrosomes

Pierre Gönczy, Alessandro De Simone

Centrosome separation along the surface of the nucleus at the onset of mitosis is critical for bipolar spindle assembly. Dynein anchored on the nuclear envelope is known to be important for centrosome separation, but it is unclear how nuclear dynein forces ...

Combination of ruthenium(II)-arene complex [Ru(eta(6)-p-cymene)Cl-2(pta)] (RAPTA-C) and the epidermal growth factor receptor inhibitor erlotinib results in efficient angiostatic and antitumor activity

Paul Joseph Dyson, Patrycja Nowak-Sliwinska, Ume-Gulsoom Abdul, Patrick Meraldi

Ruthenium-based compounds show strong potential as anti-cancer drugs and are being investigated as alternatives to other well-established metal-based chemotherapeutics. The organometallic compound [Ru(eta(6)-p-cymene) Cl-2(pta)], where pta = 1,3,5-triaza-7 ...

Discovery of a Selective Aurora A Kinase Inhibitor by Virtual Screening

Pierre Gönczy, Sachin Kotak, Maria Josefina Marcaida Lopez, Jean-Louis Reymond

Here we report the discovery of a selective inhibitor of Aurora A, a key regulator of cell division and potential anticancer target. We used the atom category extended ligand overlap score (xLOS), a 3D ligand-based virtual screening method recently develop ...

Mechanisms of centrosome separation in C. elegans

Alessandro De Simone

Centrosomes are the major microtubule organizing centers of animal cells. The two centrosomes present at the onset of mitosis must separate in a timely fashion along the nuclear envelope to ensure proper bipolar spindle assembly and thus genome stability. ...

Dynein Transmits Polarized Actomyosin Cortical Flows to Promote Centrosome Separation

Pierre Gönczy, Alessandro De Simone

The two centrosomes present at the onset of mitosis must separate in a timely and accurate fashion to ensure proper bipolar spindle assembly. The minus-end-directed motor dynein plays a pivotal role in centrosome separation, but the underlying mechanisms r ...

Cortical neurons gradually attain a post-mitotic state

Johannes Gräff

Once generated, neurons are thought to permanently exit the cell cycle and become irreversibly differentiated. However, neither the precise point at which this post-mitotic state is attained nor the extent of its irreversibility is clearly defined. Here we ...

Distinct mechanisms eliminate mother and daughter centrioles in meiosis of starfish oocytes

Pierre Gönczy

Centriole elimination is an essential process that occurs in female meiosis of metazoa to reset centriole number in the zygote at fertilization. How centrioles are eliminated remains poorly understood. Here we visualize the entire elimination process live ...

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 ...

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 ...

Dma1-dependent degradation of SIN proteins during meiosis in Schizosaccharomyces pombe

Viesturs Simanis, Andrea Krapp

The Schizosaccharomyces pombe septation initiation network (SIN) is required for cytokinesis during vegetative growth and for spore formation during meiosis. Regulation of the SIN during mitosis has been studied extensively, but less is known about its mei ...

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 ...

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

Pierre Gönczy, Graham Knott, 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 ...

Mechanisms of differential centriole inheritance in C. elegans

Lukas von Tobel

Centrosomes are the principal microtubule organizing center (MTOC) of animal cells and comprise a pair of centrioles surrounded by pericentriolar material (PCM). Centriole number must be carefully regulated to ensure bipolar spindle formation and thus fait ...

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 ...

The S-pombe cytokinesis NDR kinase Sid2 activates Fin1 NIMA kinase to control mitotic commitment through Pom1/Wee1

Viesturs Simanis

Mitotic exit integrates the reversal of the phosphorylation events initiated by mitotic kinases with a controlled cytokinesis event that cleaves the cell in two. The mitotic exit network (MEN) of budding yeast regulates both processes, whereas the fission ...
