Our research

ES cells and zebrafish to study thyroid development and thyroid disease

The main research focus of our team is the molecular dissection of the signaling mechanisms and gene networks involved in thyroid organogenesis and thyroid diseases (congenital hupothyroidism and thyroid cancer). To date, the signaling mechanisms that control the specification of endoderm-derived organs such as the thyroid, lung, liver or pancreas remain poorly understood. To tackle the question “how different cell types are specified from the gut endoderm?”,  we use the thyroid as experimental model. Thyroid organogenesis can be grossly divided into 3 phases comprising (a) thyroid precursor cell specification, (b) budding and migration of the thyroid primordium, and (c) functional differentiation of thyroid follicular cells. While some factors critical for migration, differentiation and growth of the thyroid primordium have been identified in mouse knock-out models, little is known about the molecular events involved in thyroid precursors cell specification.

Our working strategy aims to merge data obtained with two different experimental models – Thyroid cells differentiated in vitro from genetically modified ES cells and zebrafish – to elucidate the genetic basis of thyroid development, the molecular basis of thyroid cell differentiation and thyroid cancer initiation and progression.

Based on data obtained from global expression analysis of normal thyroid development In vitro or in zebrafish as well as from models of thyroid dysgenesis and thyroid cancer, a reverse genetic approach is applied by using CRISPR/Cas for creating knockout alleles of candidate genes in ES cells and zebrafish.

This will help:
-to offer new diagnostic targets (=new candidates genes) to patients with thyroid dysgenesis.
-to identify (i) the developmental thyroid tempo orchestrated by some signaling pathways controlled by the cardio vascular system which (ii) would help to build in vitro models where thyroid differentiation could be trigger by chemically defined culture conditions and in absence of any genetic manipulation. This last achievement would pave the way for a human model of in vitro thyroid differentiation and could offer unprecedented therapeutic options to patients with thyroid dysgenesis or medical thyroid ablation.
-to Identify the early events that contribute to thyroid cancer initiation and/or progression

Zebrafish models of centronuclear myopathies

Centronuclear myopathies (CNM) are the third most common type of congenital myopathies. They are characterized histologically by an increased number of centrally localized nuclei in atrophic muscle fibers. CNM can be caused by mutations in several genes: autosomal dominant mutations in the DNM2 gene coding for dynamin 2, autosomal recessive mutations in the BIN1 gene coding for amphiphysin 2 and X-linked recessive mutations in the MTM1 gene coding for myotubularin causing X-linked centronuclear myopathy.

The project aims at understanding the molecular interactions between myotubularin, amphiphysin and dynamin that are implicated in the physiopathology of centronuclear myopathies and myotonic dystrophies. These proteins are implicated in membrane trafficking and T-tubule biogenesis. Dynamin 2 levels are increased in patients with myotubular myopathy and downregulation of dynamin 2 in MTM1 KO mouse alleviates the phenotype.

Zebrafish larvae is a highly efficient tool to model muscle diseases. With the availability of large clutches size, the model allows efficient chemical screens by simply adding drugs to the water. Zebrafish could therefore be an excellent model to test the efficacy of different concentrations of dynamin 2 inhibitors.

Our second aim is to Identify the genetic causes of congenital myopathies in patients without mutations in known candidate genes. Through collaborations with several neuromuscular reference centers in Belgium, we are using an integrated approach combining a comprehensive phenotypic analysis, exome sequencing and zebrafish knock-outs to characterize in vivo new genetic variants with zebrafish lines created “à la carte”.
