We report the effect of nickel chloride on fibroblast-mediated collagen gel contraction, fibroblast migration and pattern of matrix metalloproteinase (MMP) activities expressed by human embrzonary lung fibroblasts (HELFs). After the treatment with nickel chloride, gelatin zymography, casein zymography and also western blot assay revealed a significant decrease of MMP-2 and MMP-1 active forms. M...

conclusions our results suggest that tetracyclines dose-dependently inhibit mmp-9 activity, and among the common clinical tetracyclines, minocycline provides the most potent inhibition of excess mmp-9 activity and its consequences. materials and methods an mmp-9-rich culture medium of u-937 cells was used as the source of the enzyme. serial dilutions of 5, 20, 100, 200, and 500 µm of each drug ...

PURPOSE To conduct zymographic analysis to study the matrix metalloproteinases (MMPs) and tissue inhibitor of metalloproteinases (TIMPs) in vitreous samples of patients undergoing pars plana vitrectomy as part of the treatment of vitreoretinal disease. METHODS Forty-two vitreous samples were collected at the time of pars plana vitrectomy. Diagnoses included severe (exudative) age-related macu...
