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.

Les polyphénols, l’alternative « gagnant/gagnant » aux pesticides pour protéger à la fois les plantes et les abeilles.

Dans les cinquante dernières années, la protection des espèces végétales a consisté à utiliser massivement les produits phytopharmaceutiques ou pesticides. Cependant, ces composés de synthèse sont devenus délétères pour l’ensemble des organismes vivants dont les abeilles.

Une étude impliquant quatre unités clermontoises, LMGE-PIAF-SIGMA et le GReD, fait précisément émerger un nouveau concept technologique consistant à extraire les polyphénols des plantes et les réintroduire dans l’environnement pour protéger les plantes et les abeilles. Ce procédé phytosanitaire a fait l’objet d’un dépôt de brevet.

How does a begnin tumor become cancerous?

While the evolution of cancer towards its most aggressive phases is largely studied, the mechanisms by which a benign tumour can become malignant remain poorly understood. Based on this observation, the "Nuclear Receptors and Prostate Diseases" team has developed a new model to study these early phases in Drosophila. Their work highlights the crucial role of growth factors in the transformation of the tumour. These results are published in Nature Communications (Rambur et al., 2020).
