YPEL3 mRNA and protein expression levels in NPC cell lines and tissues. a-b Quantitative RT-PCR (a) and western blotting analysis (b) of YPEL3 expression levels in NPC cell lines. c Quantitative RT-PCR analysis of YPEL3 mRNA expression levels in NPC (n = 12) and normal nasopharyngeal epithelial tissues (n = 12); d western blotting analysis of YPEL3 protein levels in NPC (T, n = 4) and normal nasopharyngeal epithelial tissues (N, n = 4). All of the experiments were performed at least three times. Data presented are the mean ± SD; the P-value was calculated using the Student t-test
