Corrigendum to “miR-375 Inhibits the Proliferation and Invasion of Nasopharyngeal Carcinoma Cells by Suppressing PDK1”

In the article titled “miR-375 Inhibits the Proliferation and Invasion of Nasopharyngeal Carcinoma Cells by Suppressing PDK1” [1], the Y-axes labelling of Figures 1(a) and 1(b) were inverted by mistake. The corrected figure is shown below and is listed as Figure 1.

Expression levels of miR-375 and PDK1 in NPC tissues and cell lines were assessed. (a, b) qRT-PCR was performed to measure expression levels of miRNAs and PDK1 in 23 normal samples and in 38 NPC samples. miR-375 is downregulated in NPC tissue, compared with normal tissue, while PDK1 is upregulated in NPC tissue, compared with normal tissue (Student's t-test, ^∗∗P < 0.01). (c, d) qRT-PCR was performed to evaluate miR-375 expression in the N69 epithelial normal nasopharynx cell line and NPC cell lines (CNE-1,CNE-2, C666-1, and HONE1). Conversely, levels of PDK1 were markedly increased in NPC cell lines, compared to NP69 (CNE-1, CNE-2, C666-1, and HONE1) (Student's t-test, ^∗P < 0.05, ^∗∗P < 0.01, and ^∗∗∗P < 0.001). Cell lines CNE-2 and CNE-1 showed the greatest difference in miR-375 expression levels when compared to NP69 cells and were used for subsequent analyses. Each assay was conducted in duplicate, three times. Values are presented ±s.e.m.
