Abstract
MMPs are zinc-dependent endopeptidases that, collectivelly, degrade all components of the ECM. They are able to remodelate the ECM during normal developmental processes such as embryogenesis and organogenesis, as well as in pathological processes such as tumoral invasion. The biological mineralization research looking for discovering the genes involved in the molecular mechanisms that control the endochondral ossification process. MMPs and their inhibitors (TIMPs and RECK) are responsable for bone matrix remodeling and, probably, determinate the level of its turnover. Our research group study the temporal-spatial expression of MMPs, TIMPs, and RECK protein in several biological mineralization processes, such as odontogenesis and amelogenesis, alveolar bone repair, palatogenesis, endochondral and intramembranous ossification by imunohistochemistry, gel zymography, in situ hybridization and Real Time PCR techniques. Thus, our goal is evaluating the temporal-spatial expression of MMP-15 (MT2-MMP), MMP-16 (MT3-MMP), MMP-17 (MT4-MMP), MMP-24 (MT5-MMP), and MMP-25 (MT6-MMP)in mice embryos and newborns during endochondral ossification by Real Time PCR, immunohistochemistry, western blot, and gel zymography.
