L’iGReD à l’assaut du Géant

L’iGReD à l’assaut du Géant

Dignes successeurs de Florin Périer et de son expérience du Puy de Dôme  sur la pression atmosphérique ,  Christophe, Adrien, Franck et Claude, membres de la « Team UCA-CNRS »,  illustrent que la recherche c’est la tête et les jambes.

Même le soleil était (un peu trop) au rendez-vous de cette 46iéme édition de La Montée du Puy de Dôme FSCT,  jumelée cette année avec les 150 ans de l’Observatoire de Physique du Globe (UCA-CNRS).

Félicitations à tous les « finishers »

Accessing the inaccessible

Accessing the inaccessible

The heterochromatic regions of eukaryotic genomes are enriched in repeated sequences and poorly accessible due to a high level of compaction. Nevertheless, heterochromatin has to retain a certain degree of accessibility to allow important DNA-related biological processes to occur, including DNA replication, DNA damage repair, maintenance of DNA methylation and transcription for small RNA production. In a new study published in Nature Communications (Bourguet et al., ), the SILENT team now shows that the histone variant H2A.W cooperates with linker histone H1 to maintain optimal accessibility of heterochromatin in Arabidopsis.

 Diversity matters

Diversity matters

Blood cell progenitors play an essential role in the cellular immune response to infection but the importance of their heterogeneity remains elusive. In collaboration with the team of Pr M. Inamdar (JNCASR- Bangalore), the team “Epigenetic regulation and hematopoiesis” revealed that Drosophila larval blood cell progenitors exhibit an unforeseen degree of diversity, which underlies a proper immune response. This study has beeen published  (Rodriguez et al., 2021) in elife.

 This study has been higlighted on the  INSB CNRS website

When LXR plays firefighters….

When LXR plays firefighters….

Chronic inflammation is a precursor mechanism supporting cancer development. Regarding the prostate, although hormone deprivation therapy significantly slows down cancer development, it triggers deep alterations in the tumor microenvironment. In its last studi, published in Genome Biology ( Bousset et al.) the NuReP team shows that the absence of nuclear receptors LXR leads to reprogramming of the tumor microenvironment, in particular the immune landscape.

 Replicate to repress

Replicate to repress

Heterochromatin, which states for highly condensed genomics regions, is mainly constituted of transcriptionally repressed repeated elements.  In its last study, published in  Genome Biology (Bourguet et al., 2020),  the SILENT team  shows that DNA polymerase epsilon, which is involved in DNA replication, plays a crucial role in maintaining both the structure and the function of heterochromatin.
