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

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. ...

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 ...

Carbon nanotube uptake in cyanobacteria for near-infrared imaging and enhanced bioelectricity generation in living photovoltaics

Vitalijs Zubkovs, Ardemis Anoush Boghossian, Alessandra Antonucci, Charlotte Elisabeth Marie Roullier, Nils Schürgers, Benjamin Paul Johanès Gabriel Lambert, Alice Judith Gillen, Melania Reggente, Mohammed Mouhib

Single-walled carbon nanotubes (SWCNTs) have unique optoelectronic properties that make them suitable for applications ranging from phototherapy to imaging and sensing, but their uptake has mainly been explored in eukaryotic cells. Here the authors explore ...

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 ...

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 ...

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 ...

Challenging endings: How telomeres prevent fragility

Joachim Lingner, Galina Glousker

It has become apparent that difficulties to replicate telomeres concern not only the very ends of eukaryotic chromosomes. The challenges already start when the replication fork enters the telomeric repeats. The obstacles encountered consist mainly of nonca ...

Physically asymmetric division of the C. elegans zygote ensures invariably successful embryogenesis

Pierre Gönczy, Radek Jankele

Asymmetric divisions that yield daughter cells of different sizes are frequent during early embryogenesis, but the importance of such a physical difference for successful development remains poorly understood. Here, we investigated this question using the ...

The makings of TERRA R-loops at chromosome ends

Joachim Lingner, Marianna Feretzaki, Rita Valador Fernandes

Telomeres protect chromosome ends from nucleolytic degradation, uncontrolled recombination by DNA repair enzymes and checkpoint signaling, and they provide mechanisms for their maintenance by semiconservative DNA replication, telomerase and homologous reco ...

A high-content RNAi screen reveals multiple roles for long noncoding RNAs in cell division

Christina Ernst

Genome stability relies on proper coordination of mitosis and cytokinesis, where dynamic microtubules capture and faithfully segregate chromosomes into daughter cells. With a high-content RNAi imaging screen targeting more than 2,000 human lncRNAs, we iden ...

Wnt-controlled sphingolipids modulate Anthrax Toxin Receptor palmitoylation to regulate oriented mitosis in zebrafish

Françoise Gisou van der Goot Grunberg, Laurence Gouzi Abrami

Oriented cell division is a fundamental mechanism to control asymmetric stem cell division, neural tube elongation and body axis extension, among other processes. During zebrafish gastrulation, when the body axis extends, dorsal epiblast cells display divi ...
