Previously, we had used cytokine antibody array test on radioresistant NPC cell line HONE-IR and its original cell line HONE1, as mentioned in our previous study (Guo et al., 2020), and found ANG to be significantly elevated in HONE1-IR cells, and significantly increased further by radiation (Figure 1A). The gene discussed is ANG; the disease is nasopharyngeal carcinoma.
