Characterisation of conditional alleles of the Schizosaccharomyces pombe cytokinesis regulator byr4

Regulation of cytokinesis is essential for the cell during its division cycle. Failure to do so can lead to aneuploidy, which can be fatal and lead to senescence or cancer. A useful model organism for studying cytokinesis in eukaryotes is Schizosaccharomyc ...

Macromolecular Crowding Is Surprisingly Unable to Deform the Structure of a Model Biomolecular Condensate

Julian Charles Shillcock

Simple Summary The cytoplasm of a living cell is a crowded place, containing hundreds of types of protein and other macromolecules. Cells reliably and continually perform thousands of biochemical reactions to maintain their health. Biomolecular condensates ...

Centromere structure and function: lessons from Drosophila

Eftychia Kyriacou

The fruit fly Drosophila melanogaster serves as a powerful model organism for advancing our understanding of biological processes, not just by studying its similarities with other organisms including ourselves but also by investigating its differences to u ...

Extensive programmed centriole elimination unveiled in C. elegans embryos

Pierre Gönczy, Nils Kalbfuss

Centrioles are critical for fundamental cellular processes, including signaling, motility, and division. The extent to which centrioles are present after cell cycle exit in a developing organism is not known. The stereotypical lineage of Caenorhabditis ele ...

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. ...

Computational design of novel protein–protein interactions – An overview on methodological approaches and applications

Bruno Emanuel Ferreira De Sousa Correia, Anthony Marchand, Alexandra Krina Van Hall-Beauvais

Protein–protein interactions (PPIs) govern numerous cellular functions in terms of signaling, transport, defense and many others. Designing novel PPIs poses a fundamental challenge to our understanding of molecular interactions. The capability to robustly ...

Principles of checkpoint override

Ahmad Sadeghi

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 ...

Phase separation in viral infections

Christina Ernst, Haohua Li

Viruses rely on the reprogramming of cellular processes to enable efficient viral replication; this often requires subcompartmentalization within the host cell. Liquid-liquid phase separation (LLPS) has emerged as a fundamental principle to organize and su ...

Intact Drosophila central nervous system cellular quantitation reveals sexual dimorphism

Kathryn Hess Bellwald, Evelyne Ruchti, Ying Shi, Brian Donal McCabe, Wei Jiao, Soumya Banerjee, Gard Spreemann, Samuel William Vernon

Establishing with precision the quantity and identity of the cell types of the brain is a prerequisite for a detailed compendium of gene and protein expression in the central nervous system (CNS). Currently, however, strict quantitation of cell numbers has ...

ER-phagy responses in yeast, plants, and mammalian cells and their crosstalk with UPR and ERAD

Maurizio Molinari

ER-phagy, literally endoplasmic reticulum (ER)-eating, defines the constitutive or regulated clearance of ER portions within metazoan endolysosomes or yeast and plant vacuoles. The advent of electron microscopy led to the first observations of ER-phagy ove ...

Variations of intracellular density during the cell cycle arise from tip-growth regulation in fission yeast

Emrah Bostan, Pascal Damian Odermatt

Intracellular density impacts the physical nature of the cytoplasm and can globally affect cellular processes, yet density regulation remains poorly understood. Here, using a new quantitative phase imaging method, we determined that dry-mass density in fis ...

Bacterial cell cycle dynamics: size regulation during exponential growth and role of polyphosphate during starvation response

Aster Louis K Vanhecke

Bacteria are the most diverse and abundant kingdom of life and have adapted to survive and thrive in habitats around the globe. When provided with ample nutrients they grow and divide at staggering rates, increasing their population exponentially. Upon nut ...

Analysis of the S. pombe Meiotic Proteome Reveals a Switch from Anabolic to Catabolic Processes and Extensive Post-transcriptional Regulation

Viesturs Simanis, Marc Moniatte, Romain Hamelin, Florence Armand, Andrea Krapp, Lucien Fabrice Krapp, Diego Chiappe

Meiotic progression in S. pombe is regulated by stage-specific gene expression and translation, changes in RNA stability, expression of anti-sense transcripts, and targeted proteolysis of regulatory proteins. We have used SILAC labeling to examine the rela ...

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 ...

DUX is a non-essential synchronizer of zygotic genome activation

Didier Trono, Sandra Eloise Kjeldsen, Delphine Yvette L Grun, Sonia Verp, Alberto De Iaco

Some of the earliest transcripts produced in fertilized human and mouse oocytes code for DUX, a double homeodomain protein that promotes embryonic genome activation (EGA). Deleting Dux by genome editing at the 1- to 2-cell stage in the mouse impairs EGA an ...

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 ...
