title: Inhibitory activity on matrix metalloproteinases and cell-proliferating activity of tissue inhibitor of metalloproteinases-1 (TIMP-1)-contrastive difference between human and bovine TIMP-1s on mouse cell proliferation.
abstract: Either human or bovine TIMP-1 inhibited matrix metalloproteinase (MMP) activities, such as collagenolytic, gelatinolytic and caseinolytic, expressed by mouse cells as well as those expressed by human cells. Bovine TIMP-1 stimulated the proliferation of both human and mouse cells, but human TIMP-1 only proliferate human cells and not mouse cells indicating that the cell-proliferating activity has more strict species specificity than MMP inhibitory activity. All the results from [(3)H]thymidine incorporation, the phosphorylation of tyrosine-containing cellular proteins and extracellular-signal-regulated protein kinases supported the cell-proliferating properties of both human and bovine TIMP-1s. Human TIMP-1 seems not to bind to TIMP-1 receptors on mouse cells.
