In addition, we detected the expression level of LINC00839 in 20 freshly frozen NPC and 10 normal nasopharyngeal epithelial tissues using RT–quantitative PCR (qPCR) and found that LINC00839 was significantly overexpressed in NPC tissues (Fig. 1B, p = 0.0037). Here, LINC00839 is linked to nasopharyngeal carcinoma.
