Decreasing NOX4 expression attenuates AP-ICAM induction of increased GSH and GCL activity. (A) The decrease in NOX4 mRNA expression after NOX4 siRNA administration is shown. (B) The effect of targeted NOX4 knockdown on GSH production in response to vehicle, AP, or AP-ICAM peptide treatment (normalized to vehicle). (C) The effect of targeted NOX4 knockdown on GCL activity in response to vehicle, AP, or AP-ICAM peptide treatment (normalized to vehicle). n=5; #p<0.001, *p<0.01; experiments performed in quadruplicate.
