Metabolism and Gene Regulation

“We intend to characterise the molecular mechanisms driving metabolic homeostasis in health and in metabolic pathologies such as diabetes and obesity.”

The rising prevalence of metabolic pathologies such as obesity, type 2 diabetes (T2D) or non-alcoholic fatty liver disease (NAFLD) constitutes a major health problem.

We use both computational and experimental approaches to identify and characterize new metabolic regulators relevant for human metabolic pathologies to uncover novel targets for the design of improved diagnostic and therapeutic strategies.

Our short-term goal is to characterize the molecular mechanisms driving obesity-associated liver disease at different stages (insulin resistance, NAFLD, nonalcoholic steatohepatitis, fibrosis or hepatocellular carcinoma) with an emphasis on the role of pre-RNA splicing and alternative splicing in this process.
