1 Furthermore, H(2)O(2) treatment not only induced GST expression but also increased intracellular maspin/GST interaction, which was inversely correlated with the level of ROS generation. Reactive Oxygen Species glutathione S-transferase kappa 1 Homo sapiens
2 Furthermore, the maspin effect on ROS generation was completely abolished by a GST inhibitor, indicating an essential role of GST in maspin-mediated cellular response to oxidative stress. Reactive Oxygen Species glutathione S-transferase kappa 1 Homo sapiens
3 Furthermore, the maspin effect on ROS generation was completely abolished by a GST inhibitor, indicating an essential role of GST in maspin-mediated cellular response to oxidative stress. Reactive Oxygen Species glutathione S-transferase kappa 1 Homo sapiens
4 Together, our data suggest a new mechanism by which maspin, through its direct interaction with GST, may inhibit oxidative stress-induced ROS generation and vascular endothelial growth factor A induction, thus preventing further adverse effects on tumor genetics and stromal reactivity. Reactive Oxygen Species glutathione S-transferase kappa 1 Homo sapiens
