Theses and Dissertations (ETD)
Methamphetamine (METH) abuse is associated with "METH mouth" characterized by rampant caries and periodontitis. Matrix metalloproteinases (MMPs) produced by gingival fibroblasts degrade the extracellular matrix (ECM) and play an important role in periodontitis and oral cancer metastasis. There is no information on effects of METH on fibroblast MMP production, or its role in periodontitis or tumor metastasis.
Objective: Determine effect of METH on gingival fibroblast MMP production and activity.
Methods: A human gingival fibroblast cell line was used. METH cytotoxicity was determined by measuring its effects on activity of a mitochondrial enzyme. Cells were cultured ± METH (1x10-6- …
