Hydrogen Peroxide 0-17 vascular cell adhesion molecule 1 Homo sapiens 26-32 19005408-4 2008 The role of Ca2+ in H2O2-induced VCAM-1 expression was investigated in beta-cell lines using an extracellular Ca2+ chelator and Ca2+-depleted media. Hydrogen Peroxide 20-24 vascular cell adhesion molecule 1 Homo sapiens 33-39 19005408-5 2008 Furthermore, H2O2-induced VCAM-1 expression was measured in beta-cells, pretreated with inhibitors of protein kinase C, phospholipase D, and phosphatidylinositol-3 kinase/Akt. Hydrogen Peroxide 13-17 vascular cell adhesion molecule 1 Homo sapiens 26-32 19005408-6 2008 Finally, H2O2-induced VCAM-1 expression was evaluated in porcine islets and rodent beta-cell lines infected with an adenovirus encoding catalase, a H2O2-removing enzyme. Hydrogen Peroxide 9-13 vascular cell adhesion molecule 1 Homo sapiens 22-28 19005408-6 2008 Finally, H2O2-induced VCAM-1 expression was evaluated in porcine islets and rodent beta-cell lines infected with an adenovirus encoding catalase, a H2O2-removing enzyme. Hydrogen Peroxide 148-152 vascular cell adhesion molecule 1 Homo sapiens 22-28 19005408-7 2008 RESULTS: H2O2 was most potent inflammatory stimulator of VCAM-1 expression in porcine islets and had the greatest effect on VCAM-1 expression by beta-cells. Hydrogen Peroxide 9-13 vascular cell adhesion molecule 1 Homo sapiens 57-63 19005408-7 2008 RESULTS: H2O2 was most potent inflammatory stimulator of VCAM-1 expression in porcine islets and had the greatest effect on VCAM-1 expression by beta-cells. Hydrogen Peroxide 9-13 vascular cell adhesion molecule 1 Homo sapiens 124-130 19005408-8 2008 Signaling pathway analysis demonstrated that extracellular Ca2+ influx was critical to H2O2-mediated VCAM-1 expression; however, protein kinase C, phospholipase D, and phosphatidylinositol-3 kinase/Akt activation were not required for VCAM-1 expression. Hydrogen Peroxide 87-91 vascular cell adhesion molecule 1 Homo sapiens 101-107 19005408-8 2008 Signaling pathway analysis demonstrated that extracellular Ca2+ influx was critical to H2O2-mediated VCAM-1 expression; however, protein kinase C, phospholipase D, and phosphatidylinositol-3 kinase/Akt activation were not required for VCAM-1 expression. Hydrogen Peroxide 87-91 vascular cell adhesion molecule 1 Homo sapiens 235-241 19005408-9 2008 Finally, catalase overexpression inhibited H2O2-induced VCAM-1 expression by islets and beta-cell lines. Hydrogen Peroxide 43-47 vascular cell adhesion molecule 1 Homo sapiens 56-62 19005408-10 2008 CONCLUSION: An extracellular calcium-dependent H2O2 pathway is the critical mediator of VCAM-1 expression by pancreatic islets and beta-cells.
