Cysu expression in a high ROS environment. a Gene array profiles of a Sod2 null mutation [10], which is known to produce high amounts of mitochondrial ROS [24]. While Cysu is highly upregulated in this mutant, but not all peroxidases are and some are significantly down regulated in the same environment. b An RT-PCR analysis confirmed that Cysu transcripts are upregulated approximately five fold in this highly prooxidative environment in the SOD2 mutant
