Functional analysis of RIP toxins from the Drosophila endosymbiont Spiroplasma poulsonii

Bruno Lemaitre, Florent François Masson, Juan Camilo Paredes Escobar, Mario Gonzalo Garcia Arraez

BackgroundInsects frequently live in close relationship with symbiotic bacteria that carry out beneficial functions for their host, like protection against parasites and viruses. However, in some cases, the mutualistic nature of such associations is put in ...

Aurora A depletion reveals centrosome-independent polarization mechanism in Caenorhabditis elegans

Pierre Gönczy, Coralie Busso, Christian Gentili, Kerstin Klinkert Fabbri, Lukas von Tobel, Marie Juliette Ségolène Pierron, Sarah Herrman

How living systems break symmetry in an organized manner is a fundamental question in biology. In wild-type Caenorhabditis elegans zygotes, symmetry breaking during anterior-posterior axis specification is guided by centrosomes, resulting in anterior-direc ...

A Dissection of Oligomerization by the TRIM28 Tripartite Motif and the Interaction with Members of the Krab-ZFP Family

Didier Trono, Priscilla Turelli, Charlène Mireille Raymonde Raclot

TRIM28 (also known as KAP1 or TIF1β) is the universal co-repressor of the Krüppel-associated box-containing zinc finger proteins (Krab-ZFPs), the largest family of transcription factors in mammals. During early embryogenesis, TRIM28 mediates the transcript ...

Hominoid-Specific Transposable Elements and KZFPs Facilitate Human Embryonic Genome Activation and Control Transcription in Naive Human ESCs

Didier Trono, Priscilla Turelli, Evaristo Jose Planet Letschert, Julien Léonard Duc, Sandra Eloise Kjeldsen, Alexandre Coudray, Julien Paul André Pontis, Julien Duc

Expansion of transposable elements (TEs) coincides with evolutionary shifts in gene expression. TEs frequently harbor binding sites for transcriptional regulators, thus enabling coordinated genome-wide activation of species- and context-specific gene expre ...

A Drosophila Model of Essential Tremor

Essential Tremor (ET) is one of the most common neurological diseases, with an estimated 7 million affected individuals in the US; the pathophysiology of the disorder is poorly understood. Recently, we identified a mutation (KCNS2 (Kv9.2), c.1137 T > A, p. ...

Role of Cnot6l in maternal mRNA turnover

Radek Jankele

Removal of poly(A) tail is an important mechanism controlling eukaryotic mRNA turnover. The major eukaryotic deadenylase complex CCR4-NOT contains two deadenylase components, CCR4 and CAF1, for which mammalian CCR4 is encoded by Cnot6 or Cnot6l paralogs. W ...

Tissue-specific enhancer repression through molecular integration of cell signaling inputs

Bart Deplancke

Drosophila leg morphogenesis occurs under the control of a relatively well-known genetic cascade, which mobilizes both cell signaling pathways and tissue-specific transcription factors. However, their cross-regulatory interactions, deployed to refine leg p ...

Remodeling of peripheral nerve ensheathment during the larval-to-adult transition in Drosophila

Soumya Banerjee, Kumar Vishal

Over the course of a 4-day period of metamorphosis, the Drosophila larval nervous system is remodeled to prepare for adult-specific behaviors. One example is the reorganization of peripheral nerves in the abdomen, where five pairs of abdominal nerves (A4-A ...

C. Elegans Immobilization Using Deformable Microfluidics For In Vivo Studies Of Early Embryogenesis And Intestinal Microbiota

Martinus Gijs, Thomas Lehnert, Matteo Cornaglia, Li Dong, Xiaopeng Huang, Jingwei Zhang

The genome of the nematode Caenorhabditis elegans shows far-reaching similarities to that of humans. C. elegans is therefore considered as a powerful model organism in biological research related to humans, for instance for the study of human diseases. Suc ...

An Integrated Microfluidic Device For C-Elegans Early Embryogenesis Studies And Drug Assays

Martinus Gijs, Pierre Gönczy, Thomas Lehnert, Matteo Cornaglia, Li Dong, Radek Jankele, Jingwei Zhang

The Caenorhabditis elegans embryo is a widely used model for the functional analysis of dynamic cellular processes, such as chromosome segregation, cytokinesis or lineage analysis. However, the conventional embryo preparation method that relies on manually ...
