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

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 ...

Epigenetic control of hox genes collinear activation during vertebrate development

Denis Duboule

Hox genes encode transcription factors essential for patterning the anterior to posterior animal body axis. In vertebrates, these genes are arranged in clusters. During development, Hox genes are activated in a time sequence that follows their physical ord ...

A G2-phase microtubule-damage response in fission yeast

Fernando Romero Balestra

Microtubules assume a variety of structures throughout the different stages of the cell cycle. Ensuring the correct assembly of such structures is essential to guarantee cell division. During mitosis, it is well established that the spindle assembly checkp ...

Transcription and chromatin organization of a housekeeping gene cluster containing an integrated beta-globin locus control region

Daniël Noordermeer

The activity of locus control regions (LCR) has been correlated with chromatin decondensation, spreading of active chromatin marks, locus repositioning away from its chromosome territory (CT), increased association with transcription factories, and long-ra ...

Centrosomes promote timely mitotic entry in C. elegans embryos

Pierre Gönczy

Several mitotic regulators, including Cyclin B1/Cdk1, are present at centrosomes prior to mitosis onset, but it is unclear whether centrosomes promote mitotic entry in vivo. Here we developed a sensitive assay in C. elegans embryos for the temporal analysi ...

Tailoring of the practical adhesion between polyethylene and galvanised steel

Véronique Michaud, Gabrielle Pax

Abstract—The practical adhesion of maleic anhydride grafted polyethylene (MAH-PE) to galvanised steel was studied using 3-point flexure tests, before and after hydrothermal ageing. Before bonding, the electro-galvanised steel was treated with γ -aminopropy ...

Formation of aminosilane-oxide interphases

Véronique Michaud, Yves Leterrier, Gabrielle Pax

The aim of this work is to understand the interactions and interphase formation mechanisms between a liquid aminosilane oligomer (γ -APS) and glass, steel or gold surfaces as a function of the pH of the liquid aminosilane. When basic liquid γ -APS (pH 11.4 ...

Regulation of protein phosphatase type 1 and cell cycle progression by PfLRR1, a novel leucine-rich repeat protein of the human malaria parasite Plasmodium falciparum

The protein called 'suppressor of the dis2 mutant (sds22+)' is an essential regulator of cell division in fission and budding yeasts, where its deletion causes mitotic arrest. Its role in cell cycle control appears to be mediated through the activation of ...

How adeno-associated virus Rep78 protein arrests cells completely in S phase

Peter Martin Beard

Adeno-associated virus Rep78 protein has antiproliferative effects on cells. It inhibits cell cycle progression, and, in particular, Rep78 induces a complete arrest within S phase, a response rarely seen after cell DNA damage. We examined how Rep78 achieve ...

lis-1 is required for dynein-dependent cell division processes in C. elegans embryos

Pierre Gönczy

We investigated the role of the evolutionarily conserved protein Lis1 in cell division processes of Caenorhabditis elegans embryos. We identified apparent null alleles of lis-1, which result in defects identical to those observed after inactivation of the ...
