Here, we treated SGC-7901 and AGS GC cell lines with different concentrations of H2O2 (0 μM, 25 μM, and 50 μM), and the result showed that ROS could enhance the activities of ABL1 and could upregulate p-NF-κB1, p-STAT3, IL-6, IL-1β, and COX2 (Figure 2(a)). The gene discussed is ABL1; the disease is gastric cancer.
