The data are shown in Figure 1A,B indicate that as we reported before in two human stomach cancer cell lines [18], three consecutive days of LDFRT (0.15 Gy) or a combination of a modified regimen of docetaxel, cisplatin, and 5-fluorouracil (mDCF) and LDFRT resulted in DUOX2 protein upregulation in the NCI-N87 stomach cancer cells. This evidence concerns the gene DUOX2 and gastric cancer.
