Carter AB, Tephly LA, Venkataraman S, Oberley LW, Zhang Y, Buettner GR, Spitz DR, Hunninghake GW: High levels of catalase and glutathione peroxidase activity dampen H2O2 signaling in human alveolar macrophages. Am J Respir Cell Mol Biol. 2004 Jul;31(1):43-53. Epub 2004 Feb 12.
Results are presented which support the hypothesis that adequate steady-state levels of hydrogen peroxide (H2O2) are required to overcome the effects of high catalase and glutathione peroxidase (GPx) expression for p38 mitogen-activated protein (MAP) kinase activation and tumor necrosis factor (TNF)-alpha gene expression in human alveolar macrophages stimulated with asbestos. |
