Finally, the C10orf55, C3orf35, C5orf38, CASC2, MEG3, MYCNOS, SFTA1P, SNHG3, and TMEM105 lncRNAs, were validated using HNSCC cell line models, which were irradiated using 2, 4, and 8 Gy of doses and compared to the non-irradiated controls (0 Gy). The gene discussed is MYCNOS; the disease is head and neck squamous cell carcinoma.
