Controlling the nucleosome by phosphorylation for DNA repair

Histone post-translational modifications control several fundamental processes on DNA, but very few phosphorylations are known. Here, Fisher, Krasinska and colleagues describe a new phosphorylation of Serine-57 of histone H3, on the globular core. They demonstrate its conservation from yeast to mammals, identify the DNA damage response kinase CHK1 as the major writer in human cells, and show that it loosens … Continue reading Controlling the nucleosome by phosphorylation for DNA repair

SUMOylation controls the rapid transcriptional reprogramming induced by chemotherapies in leukemias

Guillaume Bossis’ team showed in this manuscript published in Nucleic Acids Research that daunorubicin, the main chemotherapeutic drug used for Acute Myeloid Leukemias, a severe blood cancer…

Roche Continents 2023

Zoé Denis, a Ph.D. student in Karim Majzoub’s team at theIGMM, had the opportunity to be part of the Roche-Continents 2023 …

Transcription that (almost) never ends

The team of JC Andrau team has characterized at the genomic scale that a CTD-depleted RNA Polymerase II can still transcribe but cannot terminate transcription anymore. This results in a massive read-through phenotype, over hundreds of kb, at both ends of transcriptional units. Further on, without CTD, Pol II loses its interaction with both Mediator and Integrator complexes that most … Continue reading Transcription that (almost) never ends

G4access reveals that G-quadruplexes are critical for chromatin opening and antagonist to DNA methylation

Dans ce travail, l’équipe de JC Andrau propose une nouvelle approche permettant d’identifier des structures secondaires de l’ADN…..

TAKING CHARGE OF THE METAglut1 BLOOD TEST FOR THE DIAGNOSIS OF DE VIVO DISEASE

The collaboration between several teams from AP-HP, l’IGMM Institut de Génétique Moléculaire de Montpellier (CNRS/Université de Montpellier) and Metafora-Biosystems is a success: for the first time, a diagnostic test, METAglut1, has received a positive decision from Haute Autorité de Santé permitting the reimbursement of its costs by health insurance companies. METAglut1, a fast, reliable blood test, provides an early diagnosis … Continue reading TAKING CHARGE OF THE METAglut1 BLOOD TEST FOR THE DIAGNOSIS OF DE VIVO DISEASE

Live FRET imaging reveals low nanocompaction of heterochromatin in embryonic stem cells

In this study published in EMBO Journal and supervised by David Llères and Robert Feil, using a ….

Four CNRS Scientists from Montpellier receive the prestigious ERC grant

Nadine Laguette, winner of the Consolidator 2022 grant for her research project “Charting Cell Type-Specific Nucleic Acid Immunity (SENTINEL)” which aims to study the communication between innate immunity and essential fatty acid metabolism pathways, using adipose tissue as a model. This project will also allow the study of new pathways involved in the regulation of inflammatory responses in … Continue reading Four CNRS Scientists from Montpellier receive the prestigious ERC grant
