Team presentation

The scientific project of the Research Unit is fully centered on a post-genomic approach of the interactions between cells and extracellular matrix, applied to the decryption of the mechanisms that contribute to (i) modulation of tumor progression and (ii) aging of the extracellular matrix, a "niche" for the development of degenerative diseases, especially in the arterial wall.

In the development of these studies, we focus on cross-cutting approaches at the Biophysics-Biology-Bioinformatics interface by combining biological methods (biochemistry, molecular biology, cell biology, ...), biophotonics (confocal microscopy, 3D and 4D imaging, spectroscopies...) and molecular modeling (homology modeling, molecular dynamics, molecular docking and molecular interactions studies). The support of several high level technological platforms (Romeo supercomputer, multiscale molecular modeling, small animals imaging, cell and tissue imaging), that where initiated in our group, proves a valuable asset to the approaches we develop. We identify new drug targets and new molecules with high potential for therapeutic applications (anti-tumor matrikines, anti-aging molecules) for a pharmacology targeted to the extracellular matrix, and develop new tools for the diagnosis and prognosis.
