Achyranthes bidentata polypeptides promotes migration of Schwann cells via NOX4/DUOX2-dependent ROS production in rats

In this study, we aimed to investigate the possible mechanism underlying the ABPP-induced migration of primary cultured rat SCs. Transwell migration assays indicated that ABPP promoted SCs migration in a concentration-dependent manner by inducing production of NADPH-oxidase (NOX)-derived reactive oxygen species (ROS). Inhibition of ROS production by NOXs inhibitor apocynin (APO) or diphenyleneiodonium (DPI) partially blocked ABPP-mediated SCs migration. Furthermore, by using real-time polymerase chain reaction analysis and siRNA interference technique, we verified the participation of NOX subunit 4 (NOX4) and dual oxidase 2 (DUOX2) in ABPP-induced ROS production and consequential SCs migration. Taken together, these results demonstrated that ABPP promoted SCs migration via NOX4/DUOX2-activated ROS in SCs.
