This study, leads by G.Junion ( team Diversification of muscle and heart cells in normal and pathological conditions ), published in the journal Molecular Cell (Akhtar et al.) shows a new mechanism for regulating gene expression through modification of RNA. Using a combination of molecular biology and bioinformatics, they demonstrate that the enzymatic complex called m6A methyltransferase (MTC) enables RNA polymerase II to escape pausing and perform transcription, and thus precisely control the expression of genes responsible for the development of organisms.
James WILMOUTH , doctorant dans l’équipe Pathophysiologie moléculaire des tissus surrénaux et endocriniens, a reçu le prix Cancéropole CLARA de la meilleure communication orale dans le domaine du Cancer.
Ce prix, attribué par un jury de chercheurs du public et du privé, lui permettra d'exercer ses talents d’orateur dans un congrès International. Félicitations à lui.
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.

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

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.
