Hydrogen Peroxide 87-104 xanthine dehydrogenase Bos taurus 20-43 8185323-1 1994 The contribution of xanthine oxidoreductase (XDH + XO) to the extracellular release of hydrogen peroxide (H2O2) and intracellular H2O2 concentration in cultured bovine aortic endothelial cells (BAEC) was determined. Hydrogen Peroxide 87-104 xanthine dehydrogenase Bos taurus 45-48 8185323-1 1994 The contribution of xanthine oxidoreductase (XDH + XO) to the extracellular release of hydrogen peroxide (H2O2) and intracellular H2O2 concentration in cultured bovine aortic endothelial cells (BAEC) was determined. Hydrogen Peroxide 106-110 xanthine dehydrogenase Bos taurus 20-43 8185323-1 1994 The contribution of xanthine oxidoreductase (XDH + XO) to the extracellular release of hydrogen peroxide (H2O2) and intracellular H2O2 concentration in cultured bovine aortic endothelial cells (BAEC) was determined. Hydrogen Peroxide 106-110 xanthine dehydrogenase Bos taurus 45-48 8185323-1 1994 The contribution of xanthine oxidoreductase (XDH + XO) to the extracellular release of hydrogen peroxide (H2O2) and intracellular H2O2 concentration in cultured bovine aortic endothelial cells (BAEC) was determined. Hydrogen Peroxide 130-134 xanthine dehydrogenase Bos taurus 45-48 15905466-2 2005 We postulated that H2O2 may modulate the irreversible conversion of xanthine dehydrogenase (XDH) to XO and sought to examine mechanisms involved. Hydrogen Peroxide 19-23 xanthine dehydrogenase Bos taurus 68-90 15905466-2 2005 We postulated that H2O2 may modulate the irreversible conversion of xanthine dehydrogenase (XDH) to XO and sought to examine mechanisms involved. Hydrogen Peroxide 19-23 xanthine dehydrogenase Bos taurus 92-95 15905466-3 2005 METHODS AND RESULTS: H2O2 (100 micromol/L) decreased bovine aortic endothelial cell (BAEC) XDH protein expression, and metabolic labeling studies indicated that H2O2 stimulated conversion of XDH to XO. Hydrogen Peroxide 21-25 xanthine dehydrogenase Bos taurus 91-94 15905466-3 2005 METHODS AND RESULTS: H2O2 (100 micromol/L) decreased bovine aortic endothelial cell (BAEC) XDH protein expression, and metabolic labeling studies indicated that H2O2 stimulated conversion of XDH to XO. Hydrogen Peroxide 21-25 xanthine dehydrogenase Bos taurus 191-194 15905466-3 2005 METHODS AND RESULTS: H2O2 (100 micromol/L) decreased bovine aortic endothelial cell (BAEC) XDH protein expression, and metabolic labeling studies indicated that H2O2 stimulated conversion of XDH to XO. Hydrogen Peroxide 161-165 xanthine dehydrogenase Bos taurus 91-94 15905466-3 2005 METHODS AND RESULTS: H2O2 (100 micromol/L) decreased bovine aortic endothelial cell (BAEC) XDH protein expression, and metabolic labeling studies indicated that H2O2 stimulated conversion of XDH to XO. Hydrogen Peroxide 161-165 xanthine dehydrogenase Bos taurus 191-194 15905466-5 2005 BAPTA-AM prevented the decline in XDH by H2O2, indicating that it was calcium-dependent. Hydrogen Peroxide 41-45 xanthine dehydrogenase Bos taurus 34-37 15905466-6 2005 In keeping with calcium acting downstream of H2O2, the calcium ionophore A23187 (1 micromol/L) caused XDH-to-XO conversion, and this was not prevented by the antioxidants. Hydrogen Peroxide 45-49 xanthine dehydrogenase Bos taurus 102-105 15905466-8 2005 CONCLUSIONS: Endothelial XO and XDH expression are strongly dependent on H2O2 and calcium. Hydrogen Peroxide 73-77 xanthine dehydrogenase Bos taurus 32-35 15905466-9 2005 Stimulation of XDH conversion to XO may represent a feed-forward mechanism whereby H2O2 can stimulate further production of ROS.
