Relative lncRNA C22orf32-1 expression in NPC tissues and NPC cell lines assessed by quantitative reverse transcription polymerase chain reaction. (A) lncRNA C22orf32-1 was upregulated in 24 NPC tissues compared with 24 normal nasopharyngeal epithelial samples. (B) lncRNA C22orf32-1 presented higher expression in the NPC 6–10B cell line compared with normal nasopharyngeal epithelial NP460 cell line. The data were analyzed using 2^−ΔΔCq method and presented as the mean ± standard deviation. *P<0.05, **P<0.01, with comparisons indicated by lines. lncRNA, long non-coding RNA; NPC, nasopharyngeal carcinoma.
