Primary data for EPFL thesis "Metabolic regulation of cytokinesis in Schizosaccharomyces pombe"

Özge Uysal Özdemir

All cells need to be able to sense their environment, and adapt their metabolism, growth and cell division appropriately. In this study, I examined the response of Schizosaccharomyces pombe to a change in the carbon source and how that affects cytokinesis. ...

Exploring the mechanisms governing nuclear cGAS localization and activity

Marilena Wischnewski

Recognition of pathogen-derived molecules through germline-encoded receptors is a fundamental principle of innate immunity. Pattern recognition receptors detect specific intracellular danger signals to trigger potent immune responses. The DNA sensor cyclic ...

Identification and characterization of proteins that protect human telomeres from fragility

Anna Christina Näger

Difficulties to replicate telomeres - the ends of our chromosomes - can cause telomere shortening and genome instability. These difficulties are due to the repetitive DNA sequence and distinct structures at telomeres that challenge the semi-conservative DN ...

Robust designation of meiotic crossover sites by CDK-2 through phosphorylation of the MutS gamma complex

Alexander Woglar

Crossover formation is essential for proper segregation of homologous chromosomes during meiosis. Here, we show that Caenorhabditis elegans cyclin-dependent kinase 2 (CDK-2) partners with cyclin-like protein COSA-1 to promote crossover formation by promoti ...

Structures of SAS-6 coiled coil hold implications for the polarity of the centriolar cartwheel

Pierre Gönczy, Georgios Hatzopoulos

Centrioles are eukaryotic organelles that template the formation of cilia and flagella, as well as organize the microtubule network and the mitotic spindle in animal cells. Centrioles have proximal-distal polarity and a 9 fold radial symmetry imparted by a ...

Regulation of sedimentation rate shapes the evolution of multicellularity in a close unicellular relative of animals

Omaya Pierre Dudin

Significant increases in sedimentation rate accompany the evolution of multicellularity. These increases should lead to rapid changes in ecological distribution, thereby affecting the costs and benefits of multicellularity and its likelihood to evolve. How ...

Live-seq enables temporal transcriptomic recording of single cells

Bart Deplancke, Pernille Yde Rainer, Riccardo Dainese, Wanze Chen, Magda Zachara, Vincent Roland Julien Gardeux, Wouter Saelens, Orane Josiane Guillaume-Gentil

Single-cell transcriptomics (scRNA-seq) has greatly advanced our ability to characterize cellular heterogeneity(1). However, scRNA-seq requires lysing cells, which impedes further molecular or functional analyses on the same cells. Here, we established Liv ...

High-throughput Microfluidic Platforms for S. cerevisiae Single Cell Studies

Hon Ming Andrew Yip

Cells consume extra-cellular nutrients and resources to maintain cellular fitness. Extra-cellular conditions vary over time. Cellular programs encoded in genes adjust to adapt to the environments. Gene regulatory networks (GRNs) have evolved to be responsi ...

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

Tatiana Favez, Pierre Gönczy, Georgios Hatzopoulos

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 ...

Coordination between cell growth, division and chromosome replication cycles in mycobacteria

Gaëlle Madeleine Vuaridel

Propagation of microorganisms is based on three fundamental processes: cell growth, DNA replication, and cell division. Although important for antibacterial drug development, these processes are poorly understood in Actinobacteria, a medically important ph ...

Centromeres are dismantled by foundational meiotic proteins Spo11 and Rec8

Eftychia Kyriacou

Meiotic processes are potentially dangerous to genome stability and could be disastrous if activated in proliferative cells. Here we show that two key meiosis-defining proteins, the topoisomerase Spo11 (which forms double-strand breaks) and the meiotic coh ...
