Suppressive Activity of Vitamin D3 on Matrix Metalloproteinase Production From Cholesteatoma Keratinocytes In Vitro
There is much evidence that degradation of the extracellular matrix is essential for the development of cholesteatomas and that this is induced by activation of matrix metalloproteinases (MMPs). Vitamin D3 (VD3) has several well-recognised biological activities, including suppression of MMP production. The present study, therefore, was undertaken to examine whether VD3 could suppress MMP produc...
متن کاملExtracellular matrix of cultured bovine aortic endothelial cells contains functionally active type 1 plasminogen activator inhibitor.
The extracellular matrix (ECM) of cultured bovine aortic endothelial cells (BAEs) was analyzed by immunoblotting and reverse fibrin autography and shown to contain type 1 plasminogen activator inhibitor (PAI-1). Most PAI-1 in the ECM formed complexes with exogenously added tissue-type plasminogen activator (tPA), demonstrating that this PAI-1 was functionally active. The resulting tPA/PAI-1 com...
متن کاملEffect of vitamin D3 derivatives on cholesterol synthesis and HMG-CoA reductase activity in cultured cells.
Treatment of logarithmically growing rat intestinal epithelial cells (IEC-6) in culture with vitamin D3 (cholecalciferol), 25-hydroxy vitamin D3 (25-hydroxy cholecalciferol), 1,25-dihydroxy vitamin D3 (1,25-dihydroxycholecalciferol), and 24,25 dihydroxy vitamin D3 (24(R),25-dihydroxycholecalciferol), caused an inhibition of the cholesterol biosynthetic pathway at two separate sites. At concentr...
متن کاملPlasminogen activator and collagenase production by cultured capillary endothelial cells
Cultured bovine capillary endothelial (BCE) cells produce low levels of collagenolytic activity and significant amounts of the serine protease plasminogen activator (PA). When grown in the presence of nanomolar quantities of the tumor promoter 12-O-tetradecanoyl phorbol-13-acetate (TPA), BCE cells produced 5-15 times more collagenolytic activity and 2-10 times more PA than untreated cells. The ...
