Pathophysiology, Diagnosis & Treatments of Bone Diseases

Philippe CLEZARDIN
Director

Osteoporosis and bone metastasis induce structural alterations of the skeleton that lead to bone destruction and occurrence of pathological fractures. Despite of recent progress made to treat bone loss, there is clearly a need to better diagnose bone diseases and improve treatments of skeletal complications associated with bone diseases.

 

Our project aims at developing a translational research from basic scientific discoveries into clinical improvements in diagnosis and treatments of bone diseases.

Our scientific strategy hinges on 3 teams.

Team 1’s major objectives are to improve the prediction of fracture risk in men and women with osteoporosis. The relations between bone and certain chronic diseases will be also studied. It has become obvious (albeit little understood) that bone quality is influenced by chronic diseases and, conversely, that bone remodeling participates in the genesis of chronic diseases.

Team 2’s main objectives are to identify the underlying molecular mechanisms governing the nesting of tumour cells in the bone marrow and those that favour the formation of medullary micrometastases, the prelude required for bone metastasis formation. Additionally, new biological markers of early relapse of cancer in bone will be developed and novel therapeutics are being tested in animal models of malignant bone diseases.

Team 3’s main objectives are to study the roles of autotaxin and lysophosphatidic acid in bone physiology and benign (osteoporosis, rheumatoid arthritis) and cancerous (bone metastasis) bone pathologies.
