The present study demonstrates for the first time the effects of high hydrostatic pressure (HHP) on matrix metalloproteinase-9 (MMP-9), a major enzyme for bone tissue metabolism. Important are the relevance of MMP-9 for osteolytic processes and a strong increase of MMP-9 activity in bone tumors. The results are showing significant changes of MMP-9 activity after HHP treatment. Isolatetd and recombinant MMP-9 in part behave differently against HHP. Furthermore the sensitivity of isolated and recombinant MMP-9 against HHP is different. The present results can not yet lead to a sufficient consequence for medical application of HHP. Further studies with MMP-9 and other for bone tissue metabolism relevant proteases are necessary. In summary HHP in orthopedic surgery may represent a novel, promising methodical approach for bone tumor inactivation.
