RESEARCH

Frederic Bantignies is a CNRS Research Associate of the « Institut de Génétique Humaine » in Montpellier, France. Using Drosophila as a model organism, his research focuses on nuclear organization and gene regulation by Polycomb-group and trithorax-group proteins, which are chromatin factors involved in many cellular processes and cancers. Recently, many higher order structures along the chromatin fiber have been identified, partitioning the genomes into well-demarcated physical domains, also called “Topologically associating domains” (TADs). Specific connections among these TADs, including Polycomb domains, may participate in the functional folding of genomes into the nucleus. Since September 2012, granted by the CNRS and The Fulbright Association, he joined the lab of Ting Wu for a sabbatical year, with the aim of using the Oligopaint technology and high-throughput FISH analysis to identify the molecular networks that lay behind this specific chromosome organization.
