For my PhD, I was interested in promoting osteogenic potential and studying the effect of some combinations of different cytokines and hormones on the proliferation and osteoblastic differentiation capacities of human mesenchymal stromal cells, derived from adult bone marrow stroma.
Then, as a research fellow in the Tumors Center of the University of Brussels, I oriented my research towards the interactions between normal osteoblastic cells and metastatic mammary cancer cells. Indeed, bone tissue is the main target site for breast cancer metastases where it causes osteolysis without compensating osteoformation reaction. I also highlighted for the first time the anti-tumor effects of bisphosphonates on breast cancer cells.
I then joined the Inserm Unit 526 in Nice to investigate in details the interactions between epithelial tumor cells and their normal microenvironment. Taking advantage of the establishment of the genomic platform of Sophia-Antipolis, I performed comparative transcriptomic analyses in a model of co-culture of normal fibroblasts and lung cancer cells recently developped in the lab'. I thus identified some news genes potentially involved in the early phase of tumorigenesis. One of them (encoding stromelysin 3/MMP11) was better characterized (paracrine activity, promoter regulation...).
I next joined the team "Biology and Pathology of Osteoblasts" in Inserm Unit 606 in Paris, to develop two main goals : (1) identify new target genes/gene products in order to promote bone regeneration using cellular engineering of mesenchymal stromal precursor cells and (2) identify new target genes/gene products in order to reduce tumorigenesis especially in the primary bone tumors (osteosarcoma).
I finaly joined the team "Identification of molecular predictors and new targets for cancer treatment" in Inserm Unit 981, located in the Institut Gustave Roussy in Villejuif (France), to deepen the role of some molecular targets in osteosarcoma. It will allow the identification of therapeutic tools against metastatic part of these tumors and thus establishment of preclinical and translational researches.
