Figure 1.
Both miR-33a-5p and miR-128-3p were down-regulated in lung cancer tissues and lung cancer cell lines. MiR-33a-5p (A) and miR-128-3p (B) showed a statistically down-regulated expression in each lung cancer tissues and the matched adjacent normal tissues (n = 65, P < 0.001). The relative expression of miR-33a-5p (C) and miR-128-3p (D) in 65 paired lung cancer tissues and matched adjacent normal tissues. Results were presented as the fold-change in tumor tissues compared to adjacent normal tissues. (E) Pearson correlation coefficient showed that the relative expressions of miR-33a-5p and miR-128-3p were significantly positively correlated in lung cancer tissues (P = 0.0008). Compared with normal lung epithelial cell (BEAS-2B), the relative expressions of miR-33a-5p (F) and miR-128-3p (G) were significantly lower in four lung cancer cell lines (NCI-H1299, A549, SPC-A-1, and LTEP-a-2, P < 0.05). *P < 0.05, **P < 0.01, ***P < 0.001.
