Cellular systems produce reactive oxygen species during the process of metabolism. Oxidative stress results in the activation or repression of many genes in important signaling pathways. DNA microarrays allow for a high throughput evaluation of the changes in gene expression levels in any biological system. In this study, we describe a method to employ gene expression microarrays to study the transcriptional changes in redox-engineered cell lines that will overexpress MnSOD and/or catalase in the mitochondria.
