Oxymatrine Ameliorates Memory Impairment in Diabetic Rats by Regulating Oxidative Stress and Apoptosis: Involvement of NOX2/NOX4

<div>Knockdown of NOX2 and NOX4 reduced oxidative stress and apoptosis in SH-SY5Y cells treated with high glucose. (a, b) NOX2 and NOX4 siRNA transfection effectively reduced NOX2 and NOX4 expression levels. (c, d) NOX2 and NOX4 siRNA transfection effectively downregulated NOX2 and NOX4 expression levels in SH-SY5Y cells treated with high glucose and OMT. (e, f) NOX2 and NOX4 siRNA transfection effectively decreased ROS levels in SH-SY5Y cells treated with high glucose and OMT.
