Figure 1. MiR-346 is up-regulated in primary human lung cancer and NSCLC cell lines, and predicts a worse prognosis. (A) miR-346 is significantly increased in primary human lung cancer tissues in comparison to adjacent-normal lung cancer tissues. n=114 for each group. (B) The expression level of miR-346 in seven NSCLC cell lines and normal 16HBE cells. Assays were performed in triplicate. (C) Kaplan-Meier survival analysis revealed that up-regulated miR-346 is associated with poor prognosis in patients with non-small cell lung cancer. *P < 0.001, Means ± SEM was shown. Statistical analysis was conducted using student t-test.
