Sabine Costagliola  


Name: Costagliola

First name: Sabine

Date of birth: May 14, 1961

Nationality: French


Education: PhD Immunology 1991: PhD Medical Biology 2000


Professional positions: Qualified Research Scientist FNRS.


Research interest: The group is working on the identification of TSH receptor residues implicated in the binding of the ligand and autoantibodies from patients with Graves disease, but also in the mechanism of activation of this receptor. We developed an animal model of Graves disease from which monoclonal antibodies against TSHR were derived. They allowed the identification of sulfated Tyrosine residues, required in ligand but not autoantibodies binding. We are pursuing an extensive program of directed mutagenesis on the ectodomain of the TSHR, but also LH/CGR and FSHR, to propose a model of interaction of the hormone with its receptor.

Xavier De Deken 

First name: Xavier
Date of birth: October 03, 1975
Nationality: Belgian
- Ms Biomedical Sciences (ULB-1997)
- PhD thesis in Biomedical Sciences (ULB-2002)
Professional positions: Assistant Professor ULB - Personal investigator of the DUOX Lab (IRIBHM-ULB)
Research interest: Study of the H2O2 generator DUOX involved in oxidative stress and cancer development.
Hydrogen peroxide (H2O2) is a highly reactive chemical molecule originally considered as an antibacterial agent. In excess, H2O2 induces an oxidative stress responsible for different pathologies like cardiovascular disease, neurodegeneration, tumorigenesis or ageing. The thyroid tissue generates massive amounts of H2O2 required for the biosynthesis of thyroid hormones. In 2000, we discovered and characterized the molecular nature of the molecules responsible for this H2O2-generating system: the DUOX1 and DUOX2 enzymes. The DUOX are also present at the mucosal surface of the digestive and respiratory epithelia. Our multidisciplinary projects aim to better characterize the function of these new oxidases and to study their physiological roles in humans and using transgenic mouse models.

Nationality: French
Ph.D., Biochemistry, spec. Microbiology 1996
University Denis Diderot Paris VII (Paris, France)
Professional positions:
Senior researcher, “Stem cells of the digestive tract:  role in development, homeostasis and regeneration” group
Research interest:
The goal of our research group is to better understand the molecular and cellular mechanisms that contribute to tissue development, homeostasis and regeneration in epithelia of the digestive tract. The system used for our studies is the mouse model. We combine two kind of approaches: i) an in vivo approach, via phenotypical analysis of transgenic knock-in, knockout and Cre recombinase lines and ii) an ex vivo approach, through studies on primary cultures of mouse stem cells which can grow as organoids and keep self-renewing and differentiating for indefinite periods in a Petri dish.

B.Sc in Chemistry (1985)

PhD in Biochemistry (1991)


Professional positions:

"Chercheur Qualifié" of the Belgian Fonds National de la Recherche Scientifique


Research interest: We are interested in DNA microarrays, which are a technology that allows simultaneous monitoring of the expression levels of numerous genes. A collection of 11000 cDNAs clones normalized by substractive hybridization and partially identified from resting and activated leucocytes has been established. The examination of the transcriptional changes induced by the envelope of the virus HIV-1 in freshly isolated peripheral blood mononuclear cells is our current objective. The study of the expression profile induced by Kiss-1, a peptide ligand that suppresses metastases of human melanomas and breast carcinomas, is also under investigation. The analysis of the large amount of data generated by microarray experiments will lead to a better understanding of the intracellular cascade activated in these target cells.

Our group is involved in the study of thyroid cell proliferation and differentiation, which are stimulated by thyrotropin through the adenylyl cyclase/cAMP dependent pathway. This pathway is involved in goitrogenesis, tumor promotion and generation of hyperfunctional adenomas. Ongoing studies include the identification by molecular biology techniques (PCR-derived methods, microarrays…) of new genes regulated by cAMP, as well as the analysis of gene expression profiles in thyroid tumors by the microarray technology. The identification of differentially expressed genes between normal and tumor thyroid cells might help to identify new molecular markers for cancer diagnosis as well as new pharmacological targets.

The H2O2 generating system is the limiting step of thyroid hormone synthesis which is catalyzed by the thyroperoxydase (TPO) at the apical surface of the thyrocytes. Based on the functional homology with the leukocyte H2O2 generating system, we have cloned two thyroid specific cDNAs encoding two proteins, ThOX1 and ThOX2, members of the NADPH oxidase family. ThOX proteins are co-localized with TPO at the apical membrane of the thyrocyte and must interact with other proteins to generate H2O2. We are studying the characteristics of these proteins and their implications in thyroid diseases.

Research interest:
I have pioneered the study of thyroid cell proliferation and differentiation by defining model systems of primary cultures in serum-free medium, and have obtained the first in vitro demonstrations of the distinct cascades of mitogenic signal transduction by TSH/cAMP and growth factors/ras/MAPK. The cAMP pathway promotes both proliferation and differentiation in thyrocytes and is causatively involved in goitrogenesis, tumor promotion and generation of hyperfunctional adenomas. The positive regulation of thyroid cell cycle by cAMP is unique as it targets the assembly and activation of complexes of pre-existing cyclin D and CDK4 without involving most intermediaries of known mitogenic signaling cascades. Using two-dimensional electrophoresis to separate the phosphorylated forms of these proteins within their various complexes, we identified the activating phosphorylation of CDK4 as a direct crucial target for cell cycle regulation in various cell systems. Using various molecular, cellular, proteomic and bioinformatic approaches, we are currently (i) exploring the mechanisms of this critical CDK4 regulation that determines the inactivation of the central oncosuppressor protein pRb and the cell cycle decision in normal and cancerous cells; (ii) developing novel tools to predict whether cancer patients will benefit or not of treatments with the new CDK4 inhibitory drugs that are now approved for treatment of advanced ER+ breast cancers.

Research interests :

G-protein coupled receptors (GPCRs) constitute one of the largest family of cell surface proteins in vertebrates and invertebrates. They play a wide range of physiological functions like sensory perception, immune defense mechanisms, cell migration, hormonal control or neurotransmission. Our research aim at studying mechanisms of GPCRs activation as well as functional consequences of GPCRs homo- and hetero-oligomerization by using chemokine receptors as a model. This family contains about 20 receptors expressed on a variety of cells including immune cells, endothelial cells and neurons. GPCRs oligomerization is thought to play a important role in cells function by influencing receptor pharmacological properties, their coupling to G-proteins and their trafficking to and from the cell surface.
