A, qRT-PCR for evaluating the lncRNA-LUADT1 expression in nasopharyngeal carcinoma cancer tissues and adjacent tissues; **P < 0.01 vs. normal group; B, qRT-PCR for measuring lncRNA-LUADT1 expression in nasopharyngeal carcinoma cell lines (HONE-1, HNE) −1, CNE1, CNE2) and normal nasopharyngeal epithelial cells (NP69); **P < 0.01 vs. NP69 group; C, lncRNA-LUADT1 expressed in the nucleus and cytoplasm of HNE-1 and HONE-1 cells; **P < 0.01 vs. HONE-1 nucleus group. The gene discussed is LUADT1; the disease is nasopharyngeal carcinoma.
