PCN causes oxidative stress in NCI-H292 cells. (A) PCN is redox active, and induces the formation of ROS and RNS. (B) NCI-H292 cells were exposed to PCN at indicated concentrations in the presence or absence of GSH for 24 hr. For antioxidant treatment, NCI-H292 cells were prexposed to GSH for 60 min before PCN was added. The experiments were performed in triplicates for three times with similar results. The mean ± standard deviation (SD) from one typical experiment is shown. *p < 0.05 when comparing PCN-exposed cells against control cells exposed to 12.5 μl sterile water per milliliter of culture medium.
