MMP-9 activation in palate tissue is a dose-related effect. The representative zymogram shows bands corresponding to MMP-9 activity in tissue samples treated with MB 10-1, 10-2 and 10-4 M. The MMP-2 bands have been removed from this gel as no differences were seen. Densitometry of the MMP-9 bands showed that MB 10-1 M showed less activity than MB 10-2 M, whereas MB 10-4 M showed significantly less activation than either of the higher doses. The bar graph shows the average results in tissue from three separate experiments.
