Diphosphonates 52-66 matrix metallopeptidase 14 Homo sapiens 83-90 12842447-7 2003 CONCLUSION: We conclude that (1) the extracellular/cell-associated mechanism of bisphosphonate involves inhibition of MT1-MMP catalytic activity eventually by chelation, and that (2) intracellular mechanism involves downregulation of induced MT1-MMP mRNA and protein expression.
