  • Title: The effects of chemically modified tetracyclines (CMTs) on human keratinocyte proliferation and migration.

    Journal: Adv Dent Res; 1998 Nov; 12(2):131-5. PubMed ID: 9972137.
    Abstract:
    Chemically modified non-antimicrobial tetracycline derivatives and other low-molecular-weight synthetic matrix metalloproteinase (MMP) inhibitors inhibited keratinocyte migration. Since 72-kDa gelatinase-A (MMP-2) was the major gelatinase in our culture conditions, the results suggest that this MMP may be important in the regulation of keratinocyte mobility. On the other hand, we measured only gelatinase activities (MMP-2 and -9) present in culture medium, and therefore the results do not reveal how the inhibitors affect other MMPs as well as MMP levels close to the cell membranes. Overall, CMTs were found to be efficient in the inhibition of keratinocyte migration.
