Personal Statement

Robert Barouki is a biochemist and molecular biologist whose main research focus during the last fifteen years has been understanding the mechanisms of toxicity of environmental pollutants such as dioxin. In particular, he has studied the biological consequences following the activation of the dioxin receptor AhR. He studied the different effects triggered by different ligands of the AhR using in particular “-omics” technologies, suggesting that part of the toxicity may be related to the disruption of endogenous functions.

In addition, as head of the clinical metabolic biochemistry department, he has initiated and organized a shared mass spectrometry facility at the Necker hospital. His focus is on developing multiplex targeted proteomic and metabolonomic assays, notably in te field of metabolic diseases and in pharmacodynamics.

Selection of Research Supports

Ongoing Research Support

Constitutive Grant from Inserm and Université Paris Descartes for unit 747
As a head of an Inserm-Université Paris Descartes unit (unit 747), I receive significant yearly support from these institutions. The grant is based on the general proposal of the unit. The unit includes 5 teams (80 people), my own being the largest one and receives approximately one fourth of the unit support. The grant partially funds all our projects including those dealing with effects of dioxin in several models studied by omics technology, the interaction between pollutants, the structure of pollutant receptors as well as studies on the toxicity of alcohol and drugs. This grant represents approximately 40% of our budget.
Role: Principal Investigator`

Heals: FP7 EU grant (2013-2018)
The aim of the project is to provide molecular and cellular mechanisms of contaminant action in the context of a consortium working on human exposome.
Co-investigator

PHRC grant calcilung : (2014-2017)
pharmacodynamics of immunosuppressive drugs in lung transplantation
co-investigator

PlasticAhR (2011-2014)
ANR (National Research Agency)
The aim of this project is to obtain a crystal structure of the dioxin receptor AhR. The structure of this receptor has not been determined yet. It would allow a better assessment of the mechanisms of ligand binding. Modeling should allow prediction of binding to this receptor, an important issue for predictive toxicology. The principle investigator, Dr P Nioche, is a member the Inserm unit 747 that I chair.
Role: co-Investigator

Other grants: oncometabotox (persistent organic pollutants and metabolism), Metapop (pollutants in adipose tissue and cancer), Hepatodiox (combined effects of pollutants and nutrients on liver toxicity), Allofattox (role of adipose tissue in POP toxicokinetics), ToxAhrBrain (role of the Ah Receptor in brain functions), calcilung (VLM: calcineurin in lung transplantation)

ANR (National Research Agency)
This project allowed us to identify the effect of dioxin and persistant organic pollutants on adipose tissue differentiation and inflammation. It also allowed to study the consequences of drastic weight loss on the distribution of these pollutants, on their effects on gene expression and on the possible correlation with disease markers.
Role: Principal Investigator
