Resolving bacterial cell biology: from replisome dynamics to cell wall synthesis

Bacteria are ubiquitous single cellular organisms. Compared to eukaryotic cells, bacteria have two unique characteristics: the membrane-less nucleoid and the cell wall built of peptidoglycan (PG). In most bacteria, a single circular chromosome is compacted ...

Sequential and directional insulation by conserved CTCF sites underlies the Hox timer in stembryos

Denis Duboule, Alexandre Gauthier Aurèle Mayran, Hocine Rekaik, Célia Corinne Renée Bochaton, Lucille Delisle, Aurélie Hintermann

Temporal activation of Hox genes in mouse pseudo-embryos in vitro initiates at the anterior part of the cluster and is accompanied by asymmetric loading of cohesin. Posterior CTCF sites then successively act as transient insulators, regulating the timed tr ...

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 ...

Torsin ATPases influence chromatin interaction of the Torsin regulator LAP1

Rudolf Hovius, Beat Fierz

The inner nuclear membrane is functionalized by diverse transmembrane proteins that associate with nuclear lamins and/or chromatin. When cells enter mitosis, membrane-chromatin contacts must be broken to allow for proper chromosome segregation; yet how thi ...

Dynamic regulation of chromatin accessibility by pluripotency transcription factors across the cell cycle

Bart Deplancke, David Michael Suter, Cédric Deluz, Vincent Roland Julien Gardeux, Antonio Carlos Alves Meireles Filho, Torgil Elias Friman, Subashika Govindan

The pioneer activity of transcription factors allows for opening of inaccessible regulatory elements and has been extensively studied in the context of cellular differentiation and reprogramming. In contrast, the function of pioneer activity in self-renewi ...

Transcription facilitated genome-wide recruitment of topoisomerase I and DNA gyrase

Stewart Cole, Claudia Sala, Wareed Ahmed

Movement of the transcription machinery along a template alters DNA topology resulting in the accumulation of supercoils in DNA. The positive supercoils generated ahead of transcribing RNA polymerase (RNAP) and the negative supercoils accumulating behind i ...

Automated long-term single cell analysis of Schizosaccharomyces pombe on a microfluidic microchemostat array

Jean-Bernard Nobs

How cells grow and divide is a question that was raised more than 100 years ago. Despite years of research and in-depth knowledge of several molecular mechanisms, the complete system that regulates and coordinates both of those activities within Schizosacc ...

Isolation and Characterisation of Regulators of the Septation Initiation Network Regulators in Fission Yeast

Anupama Goyal

The septation initiation network (SIN) in Schizosaccharomyces pombe regulates cytokinesis. Cdc7p encodes the first kinase in the core SIN pathway. In this study, I performed a genetic screen to identify novel regulators of the SIN pathway by isolating spon ...

Proteins Binding to and Regulating Human Telomeric Transcripts

Katarzyna Sikora

Telomere are the protective terminal structures of linear chromosomes. The repetitive TTAGGG sequences are bound by the dedicated shelterin complex, as well as by histones carrying modifications characteristic of silent chromatin. Like the centromeric hete ...

An essential Aurora-related kinase transiently associates with spindle pole bodies during Plasmodium falciparum erythrocytic schizogony

Aurora kinases compose a family of conserved Ser/Thr protein kinases playing essential roles in eukaryotic cell division. To date, Aurora homologues remain uncharacterized in the protozoan phylum Apicomplexa. In malaria parasites, the characterization of A ...

PP2A Phosphatase Acts upon SAS-5 to Ensure Centriole Formation in C. elegans Embryos

Pierre Gönczy, Debora Keller

Centrosome duplication occurs once per cell cycle and ensures that the two resulting centrosomes assemble a bipolar mitotic spindle. Centriole formation is fundamental for centrosome duplication. In Caenorhabditis elegans, the evolutionarily conserved prot ...

Supercoiling Induces Denaturation Bubbles in Circular DNA

Giovanni Dietler

We present a theoretical framework for the thermodynamic properties of supercoiling-induced denaturation bubbles in circular double-stranded DNA molecules. We explore how DNA supercoiling, ambient salt concentration, and sequence heterogeneity impact on th ...

Lte1, Cdc14 and MEN-controlled Cdk inactivation in yeast coordinate rDNA decompaction with late telophase progression

Thierry Laroche

The mechanism of chromatin compaction in mitosis has been well studied, while little is known about what controls chromatin decompaction in early G1 phase. We have localized the Condensin subunit Brn1 to a compact spiral of rDNA in mitotic budding yeast ce ...
