Chromatin and cell biology.

(Department Genome Dynamics)

 

Leader: Giacomo CAVALLI

 

In eukaryotes, chromatin is essential for heredity. Chromatin architectures are sometimes epistatic over the DNA and impart different heritable functions to the same DNA sequence or the same function to unrelated DNA sequences. In higher eukaryotes, memory of cell fates can be maintained by regulatory proteins classified in the Polycomb Group (PcG) and the trithorax Group (trxG). PcG proteins are maintain silent states of gene expression, while trxG members maintain active chromatin states. These proteins are able to recognize regulatory states of their target genes and to maintain these states even after disappearance of the primary transcriptional regulators that have induced them in the first place. Remarkably, these states can also be transmitted to a fraction of the progeny over multiple generations. In our lab, we aim at understanding the molecular mechanisms by which PcG and trxG proteins regulate their target genes, convey inheritance of chromatin states and orchestrate development. To reach this goal, we employ a variety of complementary approaches and techniques in the areas of molecular, cellular and developmental biology, genomics and bioinformatics.

News A new epigenetic mechanism mediating tumor suppression by Polycomb proteins

The Cavalli lab shows that a complex of Polycomb group proteins has a tumor suppressor activity that depends on its specific binding to hundreds of genes involved in the control of proliferation, cell signaling and polarity. This activity was discovered in Drosophila, but the same chromosomal binding pattern is observed in differentiated human cells, suggesting that this phenomenon might be conserved in some human tumors. This study, published in the journal Nature Genetics, opens new perspectives in the field of carcinogenesis.

News Poste Ingénieur de Recherche - Campagne FSEP mobilité interne automne 2015

Un poste d'Ingénieur de recherche est disponible au sein de notre équipe.

La fonction FSEP n° B53005  d’Ingénieur en biologie, au sein de notre équipe a été affichée sur le site web national prévu à cet effet ( pour plus de détails, voir : http://web-rh.dsi.cnrs.fr/afip/owa/consult.accueil. Chercher DR13, BAP A, corps IR).  
 
IMPORTANT- Cette fonction ne peut être pourvue que par un agent CNRS (fonctionnaire titulaire et CDI)

Rappel de la Mission :
Conception, développement et expérimentation de nouvelles technologies dans le cadre des recherches de l'équipe Cavalli. En particulier, l'agent étudiera la régulation épigénétique du génome, de sa structure et de sa fonction, et du rôle des protéines Polycomb dans cette régulation avec des techniques à haut débit ainsi que des techniques moléculaires et de biologie cellulaire. Se rajoutera à cette activité, celle de lab manager concernant le 30% du temps total.

Date butoir de réception des candidatures : 13/1/2016 - Date butoir pour effectuer les entretiens : 14/1/2016
