Major Research Areas (basic and human research)

• Role of environmental chemicals in transcriptional responses, particularly nuclear receptor mediated signaling 

• Molecular signaling signature of environmental chemicals in adipose tissue and their impact on body weight loss

 

Major Research Contribution

Our long-term goal is to discover novel biological mechanisms involved in the pathogenesis of type 2 diabetes and metabolic diseases through the use of xenobiotics (i.e. foreign substances present in living organisms) and to translate this knowledge for developing new therapeutics.

To achieve this goal, we have mainly focused on the metabolic dysregulations induced by persistent organic pollutants (POPs). Using both in vitro and in vivo models, we provided the first experimental evidence that POPs could contribute to Insulin Resistance Syndrome (1). Extending this pioneer work, we demonstrated that the presence of POPs could regulate the beneficial effects of fatty fish intake (2). Translating our experimental findings to humans, we recently showed that obese individuals with normal insulin sensitivity have substantially lower circulating levels of POPs than obese individuals with insulin resistance and cardiometabolic complications (3).
