DUX-family transcription factors regulate zygotic genome activation in placental mammals

Didier Trono, Evaristo Jose Planet Letschert, Julien Léonard Duc, Sonia Verp, Andrea Coluccio, Alberto De Iaco

In animal embryos, transcription is mostly silent for several cell divisions, until the release of the first major wave of embryonic transcripts through so-called zygotic genome activation (ZGA). Maternally provided ZGA-triggering factors have been identif ...

Genetic and epigenetic inactivation of SESTRIN1 controls mTORC1 and response to EZH2 inhibition in follicular lymphoma

Elisa Oricchio, Natalya Katanayeva, Elena Battistello, Stephanie Jocelyne Sungalee, Maria Christine Donaldson, Giovanni Ciriello

Follicular lymphoma (FL) is an incurable form of B cell lymphoma. Genomic studies have cataloged common genetic lesions in FL such as translocation t(14;18), frequent losses of chromosome 6q, and mutations in epigenetic regulators such as EZH2 Using a focu ...

Solar disinfection of drinking water in PET bottles (SODIS) is a simple point-of-use technique efficient for the inactivation of many bacterial pathogens. In contrast, the efficiency of SODIS toward viruses is not well known. In this work, we studied the i ...

Dicer1 imparts essential survival cues in Notch-driven T-ALL via miR-21-mediated tumor suppressor Pdcd4 repression

Freddy Radtke, Ute Koch, Fabian Junker, Antoine Matthieu Chabloz

The modulatory function of individual microRNAs (miRNAs) in Notch-driven T-cell acute lymphoblastic leukemias (T-ALLs) has recently been established. Although protumorigenic and tumor-suppressive miRNAs are implicated in disease onset in murine models of N ...

Spatial separation of Xist RNA and polycomb proteins revealed by superresolution microscopy

Marion Leleu

In female mammals, one of the two X chromosomes is transcriptionally silenced to equalize X-linked gene dosage relative to XY males, a process termed X chromosome inactivation. Mechanistically, this is thought to occur via directed recruitment of chromatin ...

Rapid remodeling of the actin cytoskeleton in the pre- and/or post-synaptic compartments is responsible for the regulation of neuronal plasticity, which is an important process for learning and memory. Cofilin1 plays an essential role in these processes an ...

Mechanisms of Human Adenovirus Inactivation by Sunlight and UVC Light as Examined by Quantitative PCR and Quantitative Proteomics

Tamar Kohn, Romain Hamelin, Florence Armand, Franziska Sara Bosshard

Human adenoviruses (HAdV) are important pathogens in both industrialized and developing nations. HAdV has been shown to be relatively resistant to monochromatic UVC. Polychromatic UVC, in contrast, is a more effective means of disinfection, presumably due ...

RF-plasma pretreatment of surfaces leading to TiO2 coatings with improved optical absorption and OH-radical production

César Pulgarin, Juan Kiwi, Christophe Roussel, Sami Rtimi, Oualid Baghriche

Evidence is presented for the RF pretreatment of polyester enhances the TiO2 coating generation of oxidative species/radicals under a low level actinic light irradiation. After 30 min RF-plasma pretreatment of the polyester samples, the fastest bacterial i ...

This study is based on the hypothesis that viral aggregation slows the inactivation by chemical disinfectants. This slow-down depends on the aggregate size, the concentration and the reactivity of the disinfectant. In this work we test this hypothesis by e ...
