Human bone disorders: pathological role and diagnostic potential of matrix metalloproteinases.
Bone undergoes continuous remodeling under physiological and pathological conditions. Failure of the regulation of this process leads to several disorders involving bone erosion. This series of events is mainly based on the action of proteinases, particularly matrix metalloproteinases (MMPs). MMPs have been recently suggested as potential bone resorption markers which could be added to the commonly used ones, in order to predict outcome of disease processes and healing, and to monitor disease response to treatment. As for classical biochemical bone markers, MMPs are far from being applied in primary clinical diagnosis, but they could be promising in some cases for disease prognosis. MMPs as bone remodeling biomarkers could provide information that boosts our understanding of the prognosis, disease activity and pathogenesis of bone disorders. Clarifying the MMPs' role in bone remodeling and healing could potentially help predict disease progression and the effects of direct specific therapy.
