The cystine transporter (system xC−) is an antiporter of cystine and glutamate. It has relatively low basal expression in most tissues and becomes upregulated in cells under oxidative stress (OS) as one of the genes expressed in response to the antioxidant response element promoter. We have developed 18F-5-fluoroaminosuberic acid (FASu), a PET tracer that targets system xC−. The goal of this study was to evaluate 18F-FASu as a specific gauge for system xC− activity in vivo and its potential for…
