hearing loss, but the source of ROS in the inner ear remains largely unknown. Herein, we
demonstrate that NADPH oxidase (NOX) 3, a member of the NOX/dual domain oxidase
family of NADPH oxidases, is highly expressed in specific portions of the inner ear. As
assessed by real-time PCR, NOX3 mRNA expression in the inner ear is at least 50-fold
higher than in any other tissues where its expression has been observed (eg fetal kidney …
