Armelle LENGRONNE "chercheure d'avenir"

Le prix "Chercheur d'avenir 2011" décerné par la région Languedoc-Roussillon a été attribué à 38 lauréats, dont Armelle Lengronne (équipe Pasero) pour son projet "Organisation des chromosomes et stabilité du patrimoine génétique".
Ils recevront une aide financière de la région Languedoc-Roussillon entre 20 000 et 100 000 euros sur trois ans pour mener à bien leur projet de recherche.

High-resolution mapping of the 3D organization of chromosomes

[Interview of Giacomo Cavalli by TVSud (in french)]

In collaboration with researchers from the Weizmann Institute in Israel, a team from the Institut de Génétique Humaine (CNRS) has, for the first time, revealed the detailed three-dimensional architecture of chromosomes: Giacomo Cavalli and his colleagues have achieved high-resolution mapping of the different contacts that exist within and between chromosomes. They performed this feat using a new very high-throughput technique improved by the Montpellier team. This major research work should shed new light on the impact of 3D chromosome organization on genome expression and on the onset of diseases such as cancer. It is published in the journal Cell of 3 February 2012... Read more.

The cover of this issue was designed by Cyril Sarrauste de Menthière




Seminar series on Genome Dynamics

The seminars take place on Fridays, in the IGH 1st floor room, at 11:30 from Decmeber 2011 to March 2012 (7 seminars).
The programme is available on the poster.
