Novel Transgenic Lines to Analyze Renal Glutathione Redox Potential .

Reactive oxygen species (ROS) are important regulators of intracellular signaling pathways in health and disease. It is implicated that ROS may play critical roles in pathogenesis of a number of kidney diseases including diabetic nephropathy. However, due to the lack of tools for detection of redox status, our knowledge of redox dynamics is still fragmentary. In this study, we present novel zebrafish UAS transgenic lines expressing mitochondrial and cytoplasmic targeted redox fluorescent biosensors, Grx1-roGFP2 and mitoGrx1-roGFP2. As the zebrafish is an ideal animal model for intravital imaging, these transgenic zebrafish provide useful tools to analyze renal redox dynamics .
