We are interested in the development of the thyroid in the vertebrate embryo. The thyroid is an endocrine gland present in vertebrates from fish to human, secreting one hormone, thyroxin. Thyroxin is required during development (neuronal specification, metamorphosis etc.), and as a major regulator of metabolism in the adult organism.

We use zebrafish as a model organism in order to identify genes involved in thyroid development. We are currently rescreening available mutants for thyroid defects. Preliminary data reveal new factors involved in induction and differentiation processes of the thyroid tissue.
